Below, use description of drawings embodiments of the invention 1.
At first, use Fig. 1, Fig. 2, Fig. 3 that the water level control of plumbing pumping system is described.Label 4 is dual grooved Storage water tanks and is made of the first tank 4-1 and the second tank 4-2, and 2-1,2-2 are respectively that first and second that be used for tap water is put into the first tank 4-1 and the second tank 4-2 flows into valve, generally use self-acting valve.1-1 and 1-2 are for keeping in repair the gate valve of these first and second self-acting valves, and 1-3 is used to utilize connecting tube 1-8 to be communicated with the gate valve of above-mentioned first tank and second tank.And, have the 3-1 of water level detecting mechanism, the 3-2 of the water level that detects these first tanks and second tank.
Though will be described in detail later to this; but according to the water level that is detected count needs for example full water level, low water level, pump startup water level (referring to the tank water level), pump stopping water level (referring to the tank water level) if be lower than this water level with next the dally water level of protection of pump that stops immediately if at the water level of this pump that then can turn round more than water level, flow into valve and open water level, flow into the occasion that valve cuts out five kinds of water levels such as water level, then in the first water level detecting mechanism that for example constitutes, use electrode E11, E12, E13, E14, E15 by electrode bar.In the second water level detecting mechanism, use electrode E21, E22, E23, E24, E25.

Label 7-1 is first pump that is driven by the first motor 8-1, and 1-4,1-6 are located at the front and back of this pump and the gate valve that is used to keep in repair, and 6-1 is the suction pipe of this pump, and 9-1 sends the flow switch that stop signal is used in the water consumption that makes of this pump after a little while.Equally, 7-2 is second pump that is driven by the second motor 8-2, and 1-5,1-7 are located at the front and back of this pump and the gate valve that is used to keep in repair, and 6-2 is the suction pipe of this pump, and 9-2 sends the flow switch that stop signal is used in the water consumption that makes of this pump after a little while.Have again, the 11st, supply pipe, the 12, the 13rd, be arranged at pressurized tank and pressure transducer on this supply pipe.This pressure transducer detects the pressure of above-mentioned supply pipe and sends and the corresponding electrical signal of this pressure.Feedwater is in first system, and the running by first pump is fed water to the needs end by supply pipe from first tank of Storage water tank 4.In second system, the running by second pump is fed water to the needs end by supply pipe from second tank of Storage water tank 4.Now, first tank is being swept when maintenance, closing gate valve 1-4 and stop first pumping system carries out the running of second pumping system and feeds water from second tank.When second tank is overhauled, because just clear by above-mentioned explanation, thus its explanation omitted.
Among Fig. 2, R, S, T are power supplys, and ELB is a RCCB, and 52P1,52P2 start, stop the electromagnetic contactor that above-mentioned first and second motor is used.Have, INV1, INV2 are respectively the inverters that is used for first and second motor of variable speed drive again.Among Fig. 3, R, S are the control power supplys, F is a fus, TR is a transformer, SW1 is the throw over switch that manual, disconnection, automatic operation mode are changed, SW2 is the turn round selector switch of first pump or second pump that turns round of the selection when selecting manual mode by automatic operation mode throw over switch SW1, and TS is a selector switch of selecting first tank or second tank.RX is used for they are flowed into the relay that valve is changed to first tank, the first inflow valve or second tank, second, utilizes its contact RXa to change to first side, utilizes contact RXb to change to second side, and SV1, SV2 are respectively first and second self-acting valves.E11～E15 and E21～E25 are the electrode bars of above-mentioned water level detecting mechanism.
CU is a control panel, and it comprises with lower member: as their stabilized power supply Z, microprocessor CPU, the storage M (storing program and various data described later that the work of this control panel is used) of control power supply; Be used to read from the setting data of number switch DSW1 (setting for example breakout pressure), DSW2 (setting for example lower limit goal pressure of the control constant when pump carried out pressure control), DSW3 (setting for example upper limit goal pressure of the control constant when pump carried out pressure control) etc. and store the input/output port terminal I/O-1 of storage M into; Be used for respectively speed command signal N1, N2 being outputed to the input/output port terminal I/O-2 of above-mentioned first and second inverter; Be used to output to the input/output port terminal I/O-3 of above-mentioned first and second electromagnetic contactor 52P1,52P2; Be used to read from the signal of above-mentioned first and second flow switch 9-1,9-2 and store the input/output port terminal I/O-4 of storage M into; Be used to output to the input/output port terminal of above-mentioned first and second self-acting valve SV1, SV2 and be used to read that (water level signal of electrode bar E11～E15 and E21～E25) also stores the input/output port terminal I/O-7 of storage M into from above-mentioned water level detecting mechanism; Be used to export full water level, low water level, inflow valve and open, flow into the input/output port terminal I/O-6 of the various states that valve cuts out; And display unit L1～L4 (for example full water level demonstration, low water level, No. 1 machine flow into that valve is opened, No. 2 machines flow into valves and open).For example, switch condition of the startup of these each water levels and first and second pump, stop condition, first and second inflow valve is as follows.
Water level sends the full water level alarm when E11 or E21 are above, when not reaching E11 or E21, removes water level sending of full water level alarm, sending low water alarm when water level does not reach E14 or E24, is that E13 or E23 remove sending of low water alarm etc. when above at water level.Pump can not turn round when water level reaches E14 or E24 (stopping), then stops immediately if turning round, and carries out the use of water, and starting condition can not turn round before setting up.Water level is removed pump when E13 or E23 are above can not operating condition, and flowing into valve is that E13 or E23 open when following at water level, is that E12 or E22 close when above at water level.
Yet, in the water level control system of above-described plumbing pumping system, have following problem.
(1) at Storage water tank is the occasion of dual grooved, want the water flowing current separation to select switch and select water level detecting mechanism to utilize which of NO.1, NO.2 tank, select to flow into valve which utilizes, and the relay that need be used to select, thereby make circuit become complicated, cost up.
(2) if the tank selector switch is transformed into the NO.1 side, then level detector constitutes the NO.1 side, and flowing into valve also becomes the NO.1 side; If the tank selector switch is transformed into the NO.2 side, then level detector constitutes the NO.2 side, and flowing into valve also becomes the NO.2 side; For example, can not carry out following conversion: water level detecting mechanism is the NO.1 side, and flowing into valve is the NO.2 side, or water level detecting mechanism is the NO.1 side, and flowing into valve is the NO.1 side; The inflow valve is moved simultaneously.For example,, open this demand that flows in the tank that valve is stored into water the opposing party though have in the water of the tank that uses a side, can not corresponding this demand.
(3) in the occasion of Fig. 1 (Fig. 3), it is simultaneous stopping and being in the water level of cutting off the water supply at the low water level of E14 (or E24) Storage water tank and pump, Prevention Processing such as can not before cutting off the water supply, overhaul, in addition, also there is the valve of inflow to open and the simultaneous possibility of pump startup at E13 (or E23), also will considers influence power supply.
(4) tank water level detecting (NO.1, NO.2), show and give the alarm (low water level, full water level), various function (flow into threshold switch, pump running, stop) in various forms are arranged, can not standardization and become the main cause of cost up.
(5),,, thereby require to carry out H.D water level control with few radical because it is relevant with the increase of installation cost to increase radical though then can carry out the water level control of higher function if increase the detection radical of water level detecting mechanism.
So in the present embodiment, the mode by the following stated solves the problems referred to above.
Fig. 4 (a), Fig. 4 (b) are the figure that water level control and function are carried out medelling, have represented the state that can the storing state (for example full water level, low water level) of the sensed water level number (for example detection radical of electrode bar) of water level detecting mechanism and tank, state that can pump turn round and inflow valve switch.Here, these patterns are for example represented with 6 patterns from a to f.
Below, the pattern of above medelling is called water level control and functional mode.
Fig. 5 is arrangement and the water level control that compiles 6 patterns from a to f shown in Fig. 4 (a), Fig. 4 (b) and the figure of functional mode.To be described in detail it later, this pattern is set with for example number switch DSW3, and reads in and be kept at the memory section M from the input/output port terminal I/O-1 of control panel CU in advance.In Fig. 5, make numerical value 0～F of this number switch DSW3 corresponding with the water level control and the functional mode of 6 patterns from a to f.(with reference to Fig. 5) for example as follows.
Be set at 0 o'clock in value with number switch DSW3, mode (MODE) is 0, corresponding with water level control and functional mode a (being expressed as the figure a state among Fig. 4 (a)), function description is the 3P of feeler mechanism (electrode bar is 3), show full water, invalid (the sensed water level number shows full waters with two amounts in alarm, expression can't alarm), flow into the switch motion invalid (the sensed water level number has two amounts, and expression can not flow into the switch motion of valve) of valve.In addition, read in the setting data 0 of number switch DSW3,, count the state that can the regulation pump turn round with sensed water level as the processing on the program (software).Promptly; with 02H (show that with 16 system numerical tables the meaning is that 3 electrodes all do not have in the entry, common electrode and other two electrode conductions and two amounts are arranged) but expression pump operating condition; represent that with 00H pump stops (water do not enter in the tank and forbid running being the running protection water level of pump) state.Processing as software is provided with sign name TTANKF, but handles as the pump operating condition when sign is called TTANKF=02H, stops (forbidding running) state processing as pump when TTANKF=00H.For low water level demonstration, alarm too, the state processing that when TTANKF=00H, shows and give the alarm as low water level, low water level shows and alarm state is handled as removing when TTANKF=02H.
When the setting data of number switch DSW3 is 0AH (16 system number), mode (MODE) is A, water level control and functional mode are corresponding with the figure f of Fig. 4 (b), function description is the 7P of feeler mechanism (electrode bar is 7), show full water, alarm effectively, the switch motion that flows into valve is effective.Promptly; (show with TTANKF 〉=04H with 16 system numerical tables; the meaning is that 5 electrodes do not have in the entry; common electrode and other 4 electrode conductions and 4 amounts are arranged) but expression pump operating condition; represent that with TTANKF=00H pump stops (water do not enter in the tank and forbid running being the running protection water level of pump) state.(show with TTANKF 〉=03H with 16 system numerical tables, the meaning is that 4 electrodes do not have in the entry, common electrode and other 3 electrode conductions and 3 amounts are arranged) expression flows into the state that valve is opened, (show with TTANKF 〉=05H with 16 system numerical tables, the meaning is that 6 electrodes do not have in the entry, common electrode and other 5 electrode conductions and 5 amounts are arranged) expression flows into the valve closing state.(show with TTANKF≤01H with 16 system numerical tables, the meaning is that 2 electrodes do not have in the entry, common electrode and other 1 electrode conduction and 1 amount is arranged) the expression low water level state that shows and give the alarm, (show with TTANKF 〉=04H with 16 system numerical tables, the meaning is that 5 electrodes do not have in the entry, common electrode and other 4 electrode conductions and 4 amounts are arranged) represent the state that it has resetted.Have again, (show with TTANKF 〉=06H with 16 system numerical tables, the meaning is that 7 electrodes do not have in the entry, common electrode and other 6 electrode conductions and 6 amounts are arranged) the expression full water level state that shows and give the alarm, (show with TTANKF≤05H with 16 system numerical tables, the meaning is that 6 electrodes do not have in the entry, common electrode and other 5 electrode conductions and 5 amounts are arranged) represent the state that it has resetted.
The meaning of full water level is: be in closed condition though flow into valve, break down and wait water still to overflow and the water level of the maintenance that needs repairing by tank, i.e. decision for the upper water level, by control gear demonstration and the water level that gives the alarm to central monitor.
Flowing into valve closes the meaning of water level and is: fully injected water in the tank and close the water level that flows into valve.Decision is first water level under the full water level.
The meaning of pump startup water level is: fully injected water and the water level of the pump that can turn round in the tank, basically can be the last water level that pump stops (forbidding) water level, perhaps can decide, but decision is closed the next water level of water level for flowing into valve by the balance of the viewpoint that prevents fine motion and other water level.
Flowing into valve opens the meaning of water level and is: begin to inject the water level of water to tank, determine the next water level into the pump startup water level.
The meaning of low water level is: be in open mode though flow into valve, but because of the tank water level low, pump is close to the state that can't turn round and breaks down and wait and the water level of the maintenance that needs repairing, i.e. decision for the next water level of pump stopping water level, by control gear demonstration and the water level that gives the alarm to central monitor.
The meaning of pump stopping water level is: water does not enter in the tank, is used for the pump stopping water level (forbidding running) of the idle running protection of pump, determines to be the most the next water level.
In addition, though this f pattern is optimal pattern, because the restriction on the equipment reaches economically, the figure of a～f can both use.
Fig. 6 is the control circuit figure of this first mode of execution, in the prior art among Shuo Ming Fig. 3 in the structure as the number switch of operating switch, append tank selector switch SSW1, flow into valve selector switch SSW2 and timer switch DSW4, mode switch DSW5, and read in their state by input/output port terminal I/O-1 or I/O-7, whole detection units (being electrode bar in the present embodiment) of first and second tank water position detecting mechanism are connected on the terminal base TB8, and I/O-8 reads this signal in the storage of CU by the input/output port terminal.
With regard to the necessary bit number (sizes of data) of input/output port terminal I/O-8, under the situation of 5P, remove common electrode 4 bits are connected to input/output port, because two tanks are arranged, be 8 bits therefore; Under the situation of 7P 12 bits.Identical with Fig. 3 in addition.
Read in and be stored in advance the storage M of control panel CU from input/output port terminal I/O-1 as switch DSW1～DSW3, the SSW1 of these operating switchs, the setting of SSW2 or the signal of operation.In addition, replace switch DSW1～DSW3, SSW1, SSW2, also can use the operating switch with key input and operator's (being logged into control panel CU) with display unit as operating switch.
Then, utilize Fig. 7 a, Fig. 7 b～Figure 13 that water level control and function are described.These figure are flow charts of the processing sequence of expression control, are kept at as program among the storage M of control panel CU.Carry out the initial setting of the disposal, storage, record etc. of the microprocessor CPU work that is used to make CU in 700 steps of Fig. 7 a, carry out the processing that permission TIMNT (regularly interrupting), AD conversion interrupt the interruption that (pressure transducer detects reading in of data) wait in 701 steps, carry out the Interrupt Process wait in 702 steps.Thus, these Interrupt Process can be carried out at any time.
Fig. 8 represents that TIMNT (regularly interrupting) handles, and Fig. 9 represents that AD changes interruption (pressure transducer detects reading in of data) and handles.Among Fig. 8, (make water consumption few if in the processing of 801～804 steps, check the switch motion and the connection (ON) of the flow switch of first pump side, the switch closing state), then data 00H is arranged among the storage FLOW1 (representing) for convenience of storage being added title, (make water consumption many if disconnect (OFF), the state of switch opens), then data 0FFH is arranged at storage FLOW1 (representing) for convenience of storage being added title.Similarly, though omit explanation because of very clear, in 805～807 steps, check second pump side flow switch switch motion and data are arranged among the storage FLOW2 (for convenience storage being added that title represents).In 808 steps, read in the setting data of number switch DSW1～DSW4, with breakout pressure data (00H～0FFH) set in advance and be kept among the title DSW1 of storage M, with goal pressure data (00H～0FFH) set in advance and be kept among title DSW2, the DSW3 of storage M, (00H～0FFH) set in advance and be kept among the title DSW4 is with the mode data (00H～0FFH) set in advance and be kept among the title DSW5 of Fig. 6 with timer data.
Similarly, read in the setting data of tank selector switch SSW1 and inflow valve selector switch SSW2 and tank is selected data (01H: first tank, 02H: second tank) set in advance and be kept among the title SSW1 of storage M, to flow into valve and select data (01H: the first inflow valve, 02H: second flows into valve, 03H: first and second two inflow valves) set in advance and be kept among the title SSW2.And then, data with water level detecting mechanism, for example the data of E11～E15 (first tank with) and E21～E25 (second tank with) (if conducting then its bit be 1, if not conducting then its bit be 0) be kept in advance among storage name TTANKF1 (first tank with) and the storage name TTANKF2 (second tank with).Then, in 811 steps, turn back to the preceding processing division of interruption, and proceed thus to handle by this Interrupt Process.Among Fig. 9, in the processing of 902 steps, the detected pressure data of pressure transducer is set in advance and is kept among the storage name PDATA.In 904 steps, turn back to the preceding processing division of interruption by this Interrupt Process, and proceed thus to handle.
Carrying out the water level of detailed process shown in Figure 10 in main 703 steps of handling handles.Among Figure 10, check in 100 steps whether the data that are kept among the storage name SSW1 are 01H.That is, check whether tank selector switch SSW1 has selected first tank.Result of determination if first tank then enters into 101 steps, is finished counting to 1 bit of establishing that is stored in the next 4 Bit datas among the TANKF1 (first tank with) and is stored among the TTANKF1 (first tank with) at this.That is, if whole electrodes of 5P do not have in the entry, then 4 bit total datas 1 are established, and its value is 4.If 4P (4) electrode of removing beyond the common electrode leaves from water, then 4 bit total datas 0 are established, and its value is 0.For each water level of centre,, thereby omit its explanation because of clear by above stated specification.Equally, in 102,103 steps, 1 bit of establishing that is stored in the next 4 Bit datas among the TANKF2 (second tank with) is finished counting and is stored among the TTANKF2 (second tank with).So, the detection data of water level detecting mechanism are quantized.
Though omitted explanation, with the corresponding occasion of 7P electrode, in handling 101,103 steps, not only to count the next 4 bits, also to count certainly upper 4 bits.Check later on that in main 704 steps of handling the data that are stored among the storage name MODE are up to 0～A (whole modes shown in Figure 5).At first, check in 704 steps whether data are 00H (a among Fig. 4, feeler mechanism are 3P).If 00H then enters 705 steps, if not 00H then enters 708 steps.Carrying out the running of first pump shown in Figure 11 in 705 steps handles.At this, describe with the example of first pump and the second pump alternate-running.Whether the sign A LTF that checks alternate-running in 704 steps is 01H.This is masked as 01H and has then selected first pump, and this is masked as 02H and has then selected second pump.The example that with the initial value is 01H (with the example of first pump as preferential machine) describes.And, for convenience diagram has been omitted in the processing of second pump side.
Judge in 111 steps whether first pump turns round.Use first pump running sign RUNP at this.During this value was in during for 00H and stops, this value was in the running during for 01H.Result of determination is not if the later processing of 112 steps is then carried out in running, if then carry out the later processing of 119 steps in the running.Check in 112 steps whether TTANKF1 is 02H.If not 02H then enters into 126 steps, carry out the processing here repeatedly up to reaching 02H.As described above, 02H represents that water level is the pump water level that can turn round.If 02H then enters into the processing of 113～117 steps.In addition, 113 steps～116 steps have been omitted the explanation to the miscellaneous function that suppresses the pump startup frequency.Check that in 117 steps the detected feed pressure of pressure transducer is whether below breakout pressure P1 (being stored in as breakout pressure among the storage name P1).If handle and enter into 124 steps with next in 118 steps, the startup at P1.If not like that then enter into 129 steps, and carry out the processing here repeatedly up to reaching below the P1.If in the running of the result of determination in 111 steps, then enter into 119 steps, check at this whether TTANKF1 is 00H.As mentioned above, 00H be used for low water level dally the protection the pump stopping water level.
120～123 steps are carried out timer and pump stops to handle and entering into 129 steps if 00H then enters into.If not 00H then enters into 124 steps, check at this whether flow switch is connected and anhydrous use arranged.If access failure then enters into 129 steps and carries out the processing here repeatedly up to connection.Though if on has then been omitted its explanation aforementioned in 125 steps, whether time is up check to suppress the timer of startup frequency of pump.Then enter into 126 steps implementation pump stops to handle as if time is up, the running sign RUNP of first pump is set to 00H in 127 steps, alternate-running sign A LTF is set to 02H (second pump) in 128 steps, and enters into 129 steps, withdraws from the processing here.If the time does not arrive, then fall back on 129 steps in the processing of 125 steps, continuation the processing here is up to time is up.
Processing enters into main 706 steps of handling, and handles in this running of carrying out second pump.In addition, handle identical detailed because of this processing with the running of first pump.Then carrying out low water level shown in Figure 12 in 707 steps shows and the processing that gives the alarm.In Figure 12, accessing tank selection memory name SSW1 and check in 130～133 steps is first tank or second tank, the data of the detection data TTANKF1 of the water level detecting mechanism of this tank (first tank with), TTANKF2 (second tank with) are joined (133 step) among the TTANKF, in 134 steps, check whether be 00H.00H is the water level number of the low water level of water level detecting mechanism when being 3P as previously mentioned.If 00H then carries out the low water level demonstration and gives the alarm and handles and withdraw from 141 steps in 135,137 steps.In addition, carry out the processing of 136,138,139,140 steps, and the implementation low water level shows and alarm is sent the releasing processing and fallen back on 141 steps.Retreat into 729 steps and the processing of continuation after this in implementation 707 steps.In addition, omitted the explanation midway of main processing and the processing of the later mode OA of 721 steps has been described.
Certainly, though carry out the processing of 722～728 steps, the front is very clear omits its explanation because of the running of first and second pump of 722,723 steps is handled.In 724 steps, carry out the switch process of the first inflow valve shown in Figure 13.In Figure 13, in 150,151 steps, access and flow into valve selection memory name SSW2, check that having selected the first inflow valve still is the second inflow valve.If selected the first inflow valve then to enter into 152 steps, if selected second to flow into " being (YES) " later processing that valve is then carried out 151 steps.At this, illustrate that first flows into the processing of valve, omit explanation because of the processing of the second inflow valve is identical with it.Whether in 152 step inspections is below the 03H.As mentioned above, the detection number of water level detecting mechanism is to flow into the condition that valve is opened below 03H.If 03H opens processing with the next inflow valve of carrying out in 153,154 steps.In addition, in 156 steps, check whether be more than the 05H.As mentioned above, the detection number of water level detecting mechanism is to flow into the condition that valve cuts out more than 05H.Close processing if then in 157,158 steps, carry out the inflow valve more than the 05H.
, carry out 160 steps withdraw from this processing, enter into main 725 steps of handling, describe in detail, carry out the switch process of the second inflow valve though omit it thereafter.Then in 726 steps, carry out low water level and show and the processing that gives the alarm, clearly omit its detailed description because of aforementioned.Subsequently, carrying out full water level shown in Figure 14 in 727 steps shows and the processing that gives the alarm.In Figure 14, check that in 170～173 steps the storage name SSW1 that tank is selected has selected first tank or selected second tank, no matter selected tank is first tank or second tank, checks in 174 steps all whether the sensed water level number of water level detecting mechanism is more than the 06H.As mentioned above, the detection number of water level detecting mechanism is the condition that full water level shows and gives the alarm more than 06H.If then in 177～179 steps, carry out the timer processing that is used to confirm as more than the 06H more than the 06H, in 180,181 steps, carry out full water level and show and the processing that gives the alarm, thereafter, in 182 steps, withdraw from.At this, carrying out timer processing is not have the retardation phenomenon fine motion in order to prevent because of full water level.
If result of determination in 174 steps then enters into 175,176 steps less than 06H, carries out at this and removes full water level and show and give the alarm and handle and enter 182 steps and withdraw from.Below, the main processing of handling and carrying out repeatedly after this that turns back to 703 steps from 729 steps.The above main processing of handling indivedual modus operandi 0～A.
The following describes the variation of present embodiment.According to the detected water position status of water level detecting mechanism, as Fig. 4 a, Fig. 4 b, shown in Figure 5 in advance with water level control and functional modeization, parametrization and with they as value storage in memory section, read these numerical value according to water position status again.Specifically, the detection data to water level detecting mechanism in 808 steps of Fig. 8 are counted (0～6), and store in advance among memory section TTANKF1, the TTANKF2.
Other variation of present embodiment is described in addition.According to the detected water position status of water level detecting mechanism, in advance with water level control and functional modeization, parametrization and with they as value storage in memory section, automatically these numerical value are arranged to parameter according to water position status again.
And then, the other variation of present embodiment is described.Medelling, parametrization water level control and function according to water position status respectively with full water level, low water level, pump startup water level, pump stopping water level, flow into that valve is opened water level, flowing into valve, to close each function of water level relevant.
Have again, if other variation is described, then as follows, the mode of selecting tank when being set, the tank selector switch that switches first and second tank is set, the mode that selection inflow valve is set when first and second flows into the valve selector switch is being set, first tank and first and second can be flowed into the valve combination, and second tank and first and second are flowed into the valve combination.This as shown in figure 15.Be described according to Figure 16.In Figure 16, on the suction pipe 6-1 of Fig. 1, gate valve 13 is set, gate valve 14 is set on suction pipe 6-2, with between by-pass pipe 15 and gate valve 14 connection gate valves 12 and the 1-5 and between gate valve 13 and the 1-4, if be provided with like this, then for example in when maintenance of sweeping of first tank, if open gate valve 13 and open gate valve 12,14,1-4,1-5, then can be from second tank to first and second water supplying pump.Because of when maintenance of sweeping of second tank also all very clearly omitted its explanation.
In Fig. 1, open gate valve 1-3 usually, with respect to the entire pump water supply system, tank and inflow valve are selected first side or second side.But,, want promptly to be full of water sometimes to the initial period of Storage water tank and feedwater pipe arrangement water-filling etc.At this moment, as long as select above-mentioned tank selector switch simultaneously and flow into the valve selector switch, just can make both sides' inflow valve while switch.
As previously discussed, according to present embodiment, since according to the water level at water source, pump suction side with water level control and functional modeization, parametrization, and set up the water level control system of plumbing pumping system, thereby the effect that has improved operability and easy usability is not only arranged, can also improve following problem as the problem of prior art.
(1) at Storage water tank is the occasion of dual grooved, select water level detecting mechanism to utilize which of NO.1, NO.2 tank though want the water flowing current separation to select switch, select to flow into valve which utilizes, and the relay that need be used to select, thereby make circuit become complicated, cost up, but owing to tank selector switch and inflow valve selector switch be directly installed on solved this problem on the control panel.
(2),, Prevention Processing such as can not before cutting off the water supply, overhaul though to stop and being in the water level of cutting off the water supply with pump in the low water level of E14 (or E24) Storage water tank be identical in the occasion of Fig. 1 (Fig. 3).In addition, also there is the valve of inflow to open and the simultaneous possibility of pump startup, also will considers influence power supply at E13 (or E23); But timer is set has just solved this problem.
(3) if increase the detection radical of water level detecting mechanism, though then can carry out the water level control of higher function, but because it is relevant with the increase of installation cost to increase radical, thereby require to carry out H.D water level control with few radical, but water level for the function repetition, by the action that timer postpones a side is set, thereby solved this problem.
In addition, in other variation, because according to the detected water position status of water level detecting mechanism, in advance with water level control and functional modeization, parametrization and with they as value storage in memory section, but and when setting pump operating condition, pump stop condition, flow into the threshold switch condition, low water level shows alert consitions, full water level condition etc., read their these numerical value according to water position status, so, the effect that has improved operability and easy usability is not only arranged, can also obtain following improvement.。
(4) though tank water level detecting (NO.1, NO.2), show and give the alarm (low water level, full water level), various function (flow into threshold switch, pump running, stop) in various forms are arranged, can not standardization and become the main cause of cost up, but by various water levels controls and functional modeization, parametrization have been solved this problem.
In addition, in the variation of present embodiment, medelling, the control of parameterized water level and function are according to water position status, with full water level, low water level, pump startup water level, pump stopping water level, flow into that valve is opened water level, flowing into valve, to close each function of water level relevant, has the effect of raising operability and easy usability
(5) have again, because tank selector switch and first and second inflow valve selector switch that switches first and second tank is provided with the mode of selecting to flow into valve simultaneously, so can obtain following improvement.Though in the past, if the tank selector switch is transformed into the NO.1 side, then level detector constitutes the NO.1 side, and flowing into valve also becomes the NO.1 side; If the tank selector switch is transformed into the NO.2 side, then level detector constitutes the NO.2 side, and flowing into valve also becomes the NO.2 side; For example, can not carry out following conversion: water level detecting mechanism is the NO.1 side, and flowing into valve is the NO.2 side, or water level detecting mechanism is the NO.2 side, and flowing into valve is the NO.1 side; The inflow valve is moved simultaneously; But, because tank selector switch and inflow valve selector switch are directly installed on the control panel, and two switches are provided with manner of execution simultaneously, thus this problem solved.In addition, in order to implement this scheme, as shown in figure 16,, gate valve 12,13,14 and pipe arrangement 15 can suitably switch them by being set.
Though present embodiment then needn't be defined in Storage water tank to narrating to the water supply device that need side to supply with from the water of tank so long as detect the device of the water level of tank.For example, also go for discharging the distribution pump of the water of tank.Perhaps, can also be applicable to the pump that places high-order tank to supply water.
Embodiment 2
Below, use description of drawings embodiments of the invention 2.
With regard to Fig. 1～Fig. 3, omit its explanation owing to identical with embodiment 1.As mentioned above, the water level control system of the plumbing pumping system of present embodiment is used to address the problem.
(1) in the occasion of Fig. 1 (Fig. 3), it is identical stopping and being in the water level of cutting off the water supply with pump in the low water level (meaning that the water yield reduces) of E14 (or E24) Storage water tank, Prevention Processing such as can not overhaul before cutting off the water supply.In addition, also there is the valve of inflow to open and the simultaneous possibility of pump startup, also will considers influence power supply at E13 (or E23).
(2) at tank water level detecting (NO.1, NO.2), show and give the alarm (low water level, full water level), various function (flow into threshold switch, pump running, stop) in various forms are arranged, can not standardization and become the main cause of cost up.
(3),,, thereby require to carry out H.D water level control with few radical because it is relevant with the increase of installation cost to increase radical though then can carry out the water level control of higher function if increase the detection radical of water level detecting mechanism.
Therefore, in the present embodiment, the water level control system of following feed-water pump is provided, will with the control of the corresponding water level of the water level at water source, pump suction side and the action of function, each threshold parameterization that stops, and the detected water level number of the feeler mechanism that will detect water level quantizes, thereby has improved the problems referred to above.
Below, use the description of drawings embodiments of the invention.
Fig. 4 (a), Fig. 4 (b) have illustrated control of various water levels and function, have represented the state that can the storing state (for example full water level, low water level) of the sensed water level number (for example detection radical of electrode bar) of water level detecting mechanism and tank, state that can pump turn round and inflow valve switch.Here, their kind has from a to f 6 kinds.Showing distinctively by ball valve (for the structure of mechanical type action needn't be carried out switch control according to water level) and the inflow valve that need control according to the switch of water level and the sensed water level number of feeler mechanism among the figure to the water filling of Storage water tank.
Figure 17 is with 6 kinds of water levels control and the figure that gathers of the threshold parameterization that stops of the action of function and arrangement from a to f shown in Figure 4.In the figure, the dependency relation of having represented function a～f of controlled conditions and electrode bar number and Fig. 4.The situation of 4P (Fig. 4 b), 4P (Fig. 4 c), 5P (Fig. 4 d), 5P (Fig. 4 e) and so on for example.Though will be described in detail later, this parameter is for example set with operation unit, and confirms its setting content by display unit.The parameter of having set is read in and is kept at the memory section M from the input/output port terminal I/O-1 of control panel PCB.As other method, also can read in and store equally from dual-in-line switch DSW1 (P1ON), DSW2 (H00), DSW3 (H01), DSW4 (timer), DSW5 (mode).
Parameter P00 is: the control function name is that full water level shows, alarm output, operation condition (threshold value) is an electrode bar for for example water level detecting mechanism, during 3P 0FFH (presentation function is invalid), be that 03H (shows with 16 system numerical tables during 4P, the meaning is: 4 electrodes all do not have in the entry, common electrode and three conductings of other 3 electrodes), during 5P 04H (omitting explanation) because of knowing, though be 05H (omitting explanation) during not shown but 6P, during 7P 06H (omitting explanation) because of knowing because of clear.
Parameter P01 is: the control function name is expression full water level, the output of sounding all clear, and removes the alarm output that above-mentioned full water level shows.Operation condition (threshold value) is an electrode bar for for example water level detecting mechanism, during 3P 00H (presentation function is invalid), be that 02H (shows with 16 system numerical tables during 4P, the meaning is: common electrode and two conductings of other 2 electrodes), during 5P 03H (omitting explanation) because of knowing, though be 04H (omitting explanation) during not shown but 6P, during 7P 05H (omitting explanation) because of knowing because of clear.
Parameter P06 is: the control function name is to flow into valve to open output, if reach this water level with the next function that flows into valve of opening for storage of water in tank.Operation condition (threshold value) makes electrode bar for for example water level detecting mechanism, during 3P 0 (presentation function is invalid), be that 00H (shows with 16 system numerical tables during 4P, the meaning is: common electrode and other not conducting of electrode), during 5P 02H (omitting explanation) because of knowing, though be 03H (omitting explanation) during not shown but 6P, though be 02H (omitting explanation) during not shown 7P because of knowing because of clear.Also omit explanation for parameter in addition because of knowing.
In addition, it is as follows to have omitted the meaning of the parameter that describes in detail.
P02: low water level shows, alarm output
P03: low water level shows, the output of sounding all clear
P04: the pump output of can turning round
P05: stop pump idle running protection output
P07: flow into valve and close output
For example; if P04=02H (shows with 16 system numerical tables; the meaning is that 3 electrodes all do not have in the entry; common electrode and other two electrode conductions and two amounts are arranged); represent the state that pump can turn round with this; with 00H represent pump stop (not entering water in the tank and forbid the running, be the running protection water level of pump) state.Be provided with a sign name TANKF as the processing of software, but this when TANKF=02H, handle as the pump operating condition, when TANKF=00H, stop (forbidding running) state processing as pump.Similarly for low water level show, alarm, the state processing that when TANKF=00H, shows and give the alarm as low water level, low water level shows and the state processing of alarm as removing when TANKF=02H.
Secondly; the kind of water level control and function is the occasion of f; feeler mechanism is 7P (electrode bar is 7); the pump output parameter that can turn round is P04=04H; becoming TANKF 〉=04H (shows with 16 system numerical tables; the meaning is that 5 electrodes do not have in the entry; common electrode and other 4 electrode conductions and 4 amounts are arranged) and the expression pump state that can turn round; stopping pump idle running protection output parameter is P05=00H; become TANKF=00H and represent pump stop (not entering water in the tank and forbid the running, be the running protection water level of pump) state.It is P06=02H that the inflow valve is opened output parameter, becoming TANKF 〉=02H (shows with 16 system numerical tables, the meaning is that 3 electrodes do not have in the entry, common electrode and other 2 electrode conductions and 2 amounts are arranged) expression flows into the state that valve is opened, it is P07=05H that the inflow valve cuts out output parameter, become TTANKF 〉=05H (show that with 16 system numerical tables the meaning is that 6 electrodes do not have in the entry, common electrode and other 5 electrode conductions and 5 amounts are arranged) expression and flow into the valve closing state.Low water level shows, the alarm output parameter is P02=01H, becoming TANKF≤01H (shows with 16 system numerical tables, the meaning is that 2 electrodes do not have in the entry, common electrode and other 1 electrode conduction and 1 amount is arranged) the expression low water level state that shows and give the alarm, low water level shows, the output parameter of sounding all clear is P03=04H, becoming TANKF 〉=04H (shows with 16 system numerical tables, the meaning is that 5 electrodes do not have in the entry, common electrode and other 4 electrode conductions and 4 amounts are arranged) represent the state that it has resetted.Have again, full water level shows, the alarm output parameter is P00=06H, becoming TANKF 〉=06H (shows with 16 system numerical tables, the meaning is that 7 electrodes do not have in the entry, common electrode and other 6 electrode conductions and 6 amounts are arranged) the expression full water level state that shows and give the alarm, the releasing full water level shows, the alarm output parameter is P01=05H, becoming TANKF≤05H (shows with 16 system numerical tables, the meaning is that 6 electrodes do not have in the entry, common electrode and other 5 electrode conductions and 5 amounts are arranged) represent the state that it has resetted.
The meaning of full water level is: be in closed condition although flow into valve, break down and wait water still to overflow and be the water level of maintenance of needing repairing from tank, i.e. decision for the upper water level, by control gear demonstration and the water level that gives the alarm to central monitor.
Flowing into valve closes the meaning of water level and is: fully injected water in the tank and close the water level that flows into valve.Decision is first water level under the full water level.
The meaning of pump startup water level is: fully injected water in the tank and be the water level of pump of can turning round, basically can be the last water level that pump stops (forbidding) water level, perhaps can decide, but decision is closed the next water level of water level for flowing into valve by the balance of the viewpoint that prevents fine motion and other water level.
Flowing into valve opens the meaning of water level and is: begin to inject the water level of water to tank, determine the next water level into the pump startup water level.
The meaning of low water level is: be in open mode although flow into valve, but water makes the tank water level low because of breaking down etc., become pump and be close to the state that can't turn round and the water level of the maintenance that needs repairing, i.e. decision is the water level the next water level of pump stopping water level, that shown and given the alarm to central monitor by control gear.
The meaning of pump stopping water level is: water does not enter in the tank, is used for the pump stopping water level (forbidding running) of the idle running protection of pump, determines to be the most the next water level.
In addition, though this kind f is optimal pattern,, use the pattern of a～f because the restriction on the equipment reaches economically.
Fig. 6 is the control circuit figure of first mode of execution, append number switch DSW4 (timer), DSW5 (mode), tank selector switch SSW1 in the prior art among Shuo Ming Fig. 3 and flowed into valve selector switch SSW2, by being whole detection units (being electrode bar in the present embodiment) that suffix connects the water level detecting mechanism of first and second tank with input/output port terminal I/O-8, thus this signal is read in the storage of PCB.With regard to the necessary bit number (sizes of data) of input/output port terminal I/O-8, under the situation of 5P, remove common electrode and 4 bits are connected to input/output port, thereby, be 12 bits under the situation of 7P because two tanks are arranged is 8 bits.Have again, increased display unit D, operation unit O.Identical with Fig. 3 in addition.These switches DSW4, DSW5, SSW1, SSW2 sets or the signal operated reads in and is stored in advance among the storage M of control panel CU by input/output port terminal I/O-1 (having expanded the structure of Fig. 3).In addition, replace these parts, also can carry out by operation unit O, display unit D.
Then, utilize Figure 18～Figure 20 and Fig. 9 that water level control and function are described.These figure are flow charts of the processing sequence of expression control, are kept at as program among the storage M of control panel CU.Carry out the initial setting of the disposal, storage, record etc. of the microprocessor CPU work that is used to make CU in 700 steps of Figure 18 a, Figure 18 b, carry out the processing that permission TIMNT (regularly interrupting), AD conversion interrupt the interruption that (pressure transducer detects reading in of data) wait in 701 steps, carry out the Interrupt Process wait in 702 steps.Thus, these Interrupt Process can be carried out at any time.Figure 19 represents that TIMNT (regularly interrupting) handles, and Fig. 9 represents that AD changes interruption (pressure transducer detects reading in of data) and handles.In Figure 19, in the processing of 801～804 steps, check the switch motion of the flow switch of first pump side, (make water consumption few if connect (ON), the switch closing state), then data 00H is arranged among the storage FLOW1 (representing) for convenience of storage being added title, if disconnect (OFF) (making water consumption many, the state of switch opens), then data 0FFH is arranged among the storage FLOW1 (representing) for convenience of storage being added title.
Similarly, though omit explanation because of very clear, in 805～807 steps, check second pump side flow switch switch motion and data are arranged among the storage FLOW2 (for convenience storage being added that title represents).In 808 steps, read in by dual-in-line switch DSW1～DSW5, the data that SSW1～SSW2 sets, ((00H～0FFH) waits preservation in advance for 00H～0FFH), goal pressure, timer data with the parameter (parameter shown in Figure 17) of the title of storage M, breakout pressure data.Also can read in the parameter of setting by operation unit O, display unit D and replace these data.Equally, read in the setting data of tank selector switch SSW1 and inflow valve selector switch SSW2 and in advance tank is selected data (00: simultaneously, 01H: first tank, 02H: second tank) be provided with and be saved among the storage M name SSW1, to flow into valve and select data (00: simultaneously, 01H: first flows into valve, 02H: second flows into valve) be provided with and be saved among the storage name SSW2.
Have again, data with water level detecting mechanism, for example the data of E11～E15 (first tank with) and E21～E25 (second tank with) (if conducting then its bit be 1, if not conducting then its bit be 0) be kept in advance among storage name TTANKF1 (first tank with) and the storage name TTANKF2 (second tank with).After carrying out these processing, in 810 steps, turn back to the preceding processing division of interruption, proceed thus to handle by this Interrupt Process.Among Fig. 9, in the processing of 902 steps, the detected pressure data of pressure transducer is set in advance and is kept among the storage name PDATA.In 904 steps, turn back to the preceding processing division of interruption by this Interrupt Process, proceed thus to handle.
Carrying out the water level of detailed process shown in Figure 20 in main 703 steps of handling handles.Among Figure 20, check in 100 steps whether the data that are kept among the storage name SSW1 are 01H.That is, check whether tank selector switch SSW1 has selected first tank.Result of determination if first tank then enters into 101 steps, is counted and is stored among the TANKF (using as first tank) 1 bit of establishing that is stored in the data among the TANKF1 (first tank is used) at this.For example, if whole electrodes of 5P do not have in the entry, then 4 bit total datas 1 are established, and its value is 4.If 4P (4) electrode except that common electrode leaves from water, then 4 bit total datas 0 are established, and its value is 0.For each water level of centre and the water level of other pattern, because of by aforementioned clear its explanation of omitting.Equally, in 102,103 steps, 1 bit of establishing that is stored in the data among the TANKF2 (second tank is used) is counted and is stored among the TANKF (using as second tank).So, the detection data of water level detecting mechanism are quantized and these data are stored among the storage TANKF.
Turn back to main 704 steps handled and carry out this step later processing thereafter.Promptly; carrying out running with 704～706 steps handles; stop to handle (idle running protection) with the implementation of 707～709 steps; carry out full water level demonstration, alarm processing with 710～712 steps; carry out the demonstration of releasing full water level, alarm processing with 713～715 steps; carry out the inflow valve with 716～718 steps and open processing, carry out the inflow valve in 719～721 steps and close processing.In addition, low water level shows, alarm is handled and remove that low water level shows, alarm handle because of by aforementioned known omit its diagram and explanation.In 704 steps, read the data of parameter P04, with the detection data TANKF comparison of water level detecting mechanism, but judge whether operating condition is set up.But under the situation that operating condition is set up, enter into next 705 steps; Then enter into 707 steps if be false.Carrying out in 704 steps to turn round handles and enters into 707 steps.But operating condition as shown in Figure 5, is example as if Fig. 4 e that is 5P with electrode bar for example, then stores 02H among the parameter P04.In the comparison of 704 steps, if the value 02H of TANKF or set up than its bigger then condition, if be false than the little then condition of 02H.For the pattern except that Fig. 4 e because of by aforementioned clear its explanation of omitting.The turned round processing of 705 steps is with the example of first and second pump alternate-running, and the example of first pump as preferential machine described.
Certainly, under this state, be in operating condition but the water level of tank is higher.When the detected feed pressure of pressure transducer becomes breakout pressure P1 (being stored in as breakout pressure among the storage P1) first pump startup when following, if along with the minimizing flow switch that makes water consumption is connected (ON) (being stored among the storage name FLOW1) and then stopped.Subsequently, if above-mentioned starting condition is set up, then be second pump startup specifically.This pump stops if stop condition is set up then.Below, carry out alternate-running like this.In 707 steps, read the data of parameter P05, the detection data TANKF of itself and water level detecting mechanism is compared, judge whether the condition that the protection that stops to dally is handled is set up.Result of determination under the situation that condition is set up, enters into 708 steps; Enter into 710 steps under the invalid situation.Judge in 708 steps whether pump turns round, if on-stream then in next 709 steps, carry out be used for pump idle running protection (water level of tank low and be in the state that can't turn round) promptly stop to handle.If in stopping, then entering into 710 steps.Stop condition if for example electrode bar is the example of Fig. 4 e of 5P, then stores 00H as shown in figure 17 in parameter P05.By the comparison in 707 steps, if the value of TANKF be 00H then condition set up, if not 00H then condition be false.In 710 steps, read the data of parameter P00, the detection data TANKF of itself and water level detecting mechanism is compared, judge that full water level shows, whether the alarm treatment conditions are set up.Then enter into 711 steps if condition is set up, judge whether exported full water level demonstration, alarm, if output does not then enter into next 712 steps at this.Handle in this output full water level demonstration, alarm.Enter into next 713 steps thereafter.Also enter into 713 steps being judged to be under the situation not of 710 and 711 steps.Full water level shows, alarm is handled and remove the full water level demonstration, alarm is handled by aforementioned clear its explanation of omitting.
In 716 steps, read the data of parameter P06, the detection data TANKF of itself and water level detecting mechanism is compared, judge that flowing into valve opens output condition and whether set up.In next 717 steps that enter into of situation of condition establishment, judge at this whether flow into valve has been in open mode, then do not enter into 718 steps and open processing if be in open mode at this implementation inflow valve.Result of determination in 716,717 steps enters into next 719 steps for situation not is next.The condition that the inflow valve is opened if for example the electrode bar of water level detecting mechanism is the situation of Fig. 4 e of 5P, then stores 02H as shown in figure 17 in parameter P06.By the comparison in 716 steps, if TANKF is 02H or sets up than its littler then condition, as if being false than the big then condition of 02H.For the pattern except that Fig. 4 e because of by aforementioned clear its explanation of omitting.In addition, for flow into valve close processing also because of by aforementioned known omit its explanation., return 703 steps, carry out the later processing of this step repeatedly thereafter.
As mentioned above, because setting control function shown in Figure 17 according to radical, the kind of water level control function, the pattern of water level detecting mechanism is parameter P00～P0B, even thereby changes of function also can shared control gear, even the function change also can come the corresponding convenience that improve by variation of parameter.
As mentioned above in the present embodiment, as Figure 17, shown in Figure 19, the threshold parameterization that the work of the control of each water level and each function is stopped, and with setting device it is set and is stored in the storage.
And, as Figure 17, shown in Figure 19, control of a plurality of water levels and function be full water level, low water level, pump startup water level, pump stopping water level, flow into valve opens water level, flows into valve and close water level, for the work of these water levels, stop to set with they work, stop corresponding parameter, utilize setting device to set these parameters and be stored in the storage.
Have again; water level detecting mechanism is an electrode bar; this electrode is the occasion of 4P; (1) flow into valve and close water level and full water level, (2) flow into valve and open water level and the pump water level that can turn round, and it is identical water level with low water level that stopping water level is protected in the idle running of (3) pump; output inflow valve cuts out when becoming the water level of above-mentioned (1) work; make timer 1 work, time is up when this timer 1, and send the full water level alarm when satisfying the working water level condition.That is, in Figure 21, the processing of the timer 1 of steps performed 711a, 711b, 711c before the full water level output of 712 steps postpones full water level demonstration, alarm processing.Since flow into valve close that treatment conditions show with full water level, alarm handle identical, thereby the preferential inflow valve of carrying out cuts out processing.712a, 711d are that the replacement of timer 1 is handled.In addition, Figure 21 is the figure that has increased this processing in Figure 18 a, Figure 18 b.The setting value of timer 1 is similarly set with above-mentioned each parameter shown in the parameter of Figure 17 in advance.When making this timer 1 invalid as long as its value is set at 0.Flow into valve in the water level time output that becomes above-mentioned (3) work and open, make timer 2 work, time is up when this timer 2, and the rear pump water level that can turn round when satisfying the working water level condition.That is, in Figure 22, the pump of 706 steps can turn round handle before the processing of timer 2 of steps performed 705a, 705b, 705c, postpone pump and can turn round and handle output.Since flow into valve to open treatment conditions and the pump treatment conditions that can turn round identical, thereby the preferential inflow valve of carrying out is opened processing.
706a, 705d are that the replacement of timer 2 is handled.In addition, Figure 22 is the figure that has increased this processing in Figure 18 a, Figure 18 b.The setting value of timer 2 is similarly set with above-mentioned each parameter shown in the parameter of Figure 17 in advance.When making this timer 2 invalid, need only its value is set at 0.Rear pump idle running protection water level when becoming the water level of above-mentioned (2) work makes timer 3 work, and time is up when this timer 3, and carries out low water alarm when satisfying the working water level condition.That is, in Figure 23, the processing of the timer 3 of steps performed 731,732,736 before low water level demonstration, the alarm of 733 steps are handled postpones this low water level demonstration, alarm processing.Because the condition that pump idle running protection stops to handle shows with this low water level, the alarm processing is identical, stop to handle thereby preferentially carry out pump idle running protection.734, the 735th, the replacement of timer 3 is handled.In addition, though Figure 23 has omitted diagram, in Figure 18 a, Figure 18 b, increased the figure of this processing.The setting value of timer 3 is similarly set with above-mentioned each parameter shown in the parameter of Figure 17 in advance.When making this timer 3 invalid as long as its value is set at 0.
Have again; water level detecting mechanism is an electrode bar; this electrode is the occasion of 5P; (1) flows into valve and open water level and the pump water level that can turn round; and (2) pump idle running protection stopping water level is identical water level with low water level, and output inflow valve is opened when becoming the water level of above-mentioned (1) work, makes timer 2 work; time is up when this timer 2, and the rear pump water level that can turn round when satisfying the working water level condition.Rear pump idle running protection stopping water level when becoming the water level of above-mentioned (2) work makes timer 3 work, and time is up when this timer 3, and sends low water alarm when satisfying the working water level condition.Timer 2,3 processing omit its explanation because of the mode that illustrated with the front is identical.
As mentioned above, in the present embodiment, according to the water level at water source, pump suction side and with water level control and the work of function, the threshold parameterization that stops, the water level control system of having constructed the feed water pump device, thereby have the effect that improves operability and easy usability.And control gear can be shared.In addition, also has following effect.
(1) in the occasion of Fig. 1 (Fig. 3), it is identical stopping and being in the water level of cutting off the water supply with pump in the low water level of E14 (or E24) Storage water tank, Prevention Processing such as can not overhaul before cutting off the water supply.In addition, also there is the valve of inflow to open and the simultaneous possibility of pump startup, also will considers influence, but eliminate this problem by timer is set to power supply at E13 (or E23).
(2),,, thereby require to carry out H.D water level control with few radical because it is relevant with the increase of installation cost to increase radical though can carry out the water level control of higher function if increase the detection radical of water level detecting mechanism; But the water level that repeats for function by the action that timer postpones a side is set, thereby has solved this problem.
