One end of described master control circuit obtains signal from power supply 10, and the signal that obtains transfers to constant voltage water pump 60 inputs via switch 20, fuse 30, isolating transformer 40, control circuit; By the input end interface number decision master control circuit number of constant voltage water pump 60, every master control circuit structure is identical; Described signal is voltage or current signal.
In described master control circuit, electromagnetic relay is often made war and 81 is played signal and transmit.When signal input quantity reaches electromagnetic relay 80 and touches chalaza, normal 81 closures of making war of described electromagnetic relay, signal transfers to electrothermal relay 50; Comprise a thermal element in the described electrothermal relay 50; this thermal element is according to the thermal property of self; when the electric current of flowing through is excessive; when promptly the heat of being changed by the electric current acting has surpassed the rated value of electrothermal relay 50; trigger switch in the electrothermal relay 50 disconnects; circuit interrupts thereupon, has protected the constant voltage water pump 60 can trouble free service.
Transmit signal by isolating transformer 40 between master control circuit and control circuit; Described isolating transformer 40 will transfer to control circuit after the signal that master control circuit inserts is changed; In the present embodiment, described isolating transformer 40 is that the high voltage signal that will obtain from described master control circuit is converted to the required low voltage signal of control circuit.
Described control circuit comprises that gauge tap 11, auxiliary selenoid relay normally open point 82, the time relay often make war 91, auto-pressure switch 61, electromagnetic relay 80, the normally closed point 51 of electrothermal relay, the time relay 90 and dynamic recorder 70; After the branch road that described dynamic recorder 70 and the time relay 90 and electromagnetic relay 80 and the normally closed point 51 of electrothermal relay are connected in series was in parallel, an end was connected with auto-pressure switch 61, and the other end is connected with described isolating transformer 40; Normal 91 branch roads that are in series of making war of the described auxiliary selenoid relay normally open point 82 and the time relay are in parallel with auto-pressure switch 61; Described gauge tap 11 is a double contact switch, and the one end links to each other with isolating transformer 40, and one of them contact of the other end is connected with auto-pressure switch 61, and another contact connects the branch road that described electromagnetic relay 80 and the normally closed point 51 of electrothermal relay are connected in series.
Described auto-pressure switch 61 can transfer closure state to by off-state automatically when system pressure reduces, when system pressure raises, then transfer off-state to by closure state automatically.
Fig. 3 is a dynamic recorder structure chart of the present invention, and as shown in Figure 3, described dynamic recorder comprises that successively counter 71, auxiliary reclay 72, the auxiliary reclay of serial connection often make war 73 and device 75 for a long time; Described dynamic recorder 70 be connected in series branch road and 90 parallel connections of time relay formed of back by electromagnetic relay 80 and the normally closed point 51 of electrothermal relay, guaranteed to obtain synchronously information; Described counter (71) and device (75) for a long time by described auxiliary reclay (72) often make war with auxiliary reclay (73) be connected; The number of starts of described counter (71) record constant voltage water pump (60); Running time after the each startup of described for a long time device (75) record constant voltage water pump (60); In addition, for preventing data deviation, also need at the described auxiliary reclay capacitor 74 that an appearance value in parallel is 0.1 μ f on normal battle.
Described gauge tap 11 can be selected manual control, control or disconnection automatically; When described gauge tap 11 was selected manually control, signal directly transferred to the circuit that branch road that described dynamic recorder 70 and the time relay 90 and electromagnetic relay 80 and the normally closed point 51 of electrothermal relay be connected in series is formed in parallel; When selecting control automatically, signal transfers to the circuit that branch road that described dynamic recorder 70 and the time relay 90 and electromagnetic relay 80 and the normally closed point 51 of electrothermal relay be connected in series is formed in parallel via the pressure judgement unit.
After control circuit obtains signal via isolating transformer 40 from master control circuit, by the different control modes control constant voltage water pump of the gauge tap 11 selected.When described gauge tap 11 was selected manually control, described dynamic recorder 70, electromagnetic relay 80 and time relay 90 be picked up signal simultaneously; Subsequently, electromagnetic relay 81 closures of often making war, signal transfers to constant voltage water pump 60 via electrothermal relay 50, guarantees constant voltage water pump 60 trouble free services simultaneously and obtains the dynamic statistics data of the ruuning situation of constant voltage water pump 60.
When selecting control automatically, because of auxiliary selenoid relay normally open point 82 and the time relay all are in off-state normal battle 51, signal directly transfers to auto-pressure switch 61; Pressure condition transmission signal in the constant voltage water pump 60 that described auto-pressure switch 61 can determine according to built-in Pressure gauge.
When system pressure reduced, auto-pressure switch 61 transferred closure state to by off-state, and signal transfers to electromagnetic relay 80 and normally closed point 51 serial connection branch road, the time relay 90 and the dynamic recorders 70 of electrothermal relay thereupon; Counter 71 and for a long time device 75 startups in the dynamic recorder 70.
At this moment, electromagnetic relay often makes war 81, auxiliary selenoid relay normally open point 82 and normal 91 closures of making war of the time relay, and signal transfers to electrothermal relay 50, in electrothermal relay 50 nominal working ranges, drives constant voltage water pump 60 trouble free services; If exceed electrothermal relay 50 nominal working ranges, electrothermal relay 50 internal trigger switches disconnect, and constant voltage water pump 60 quits work.
After system pressure raise, auto-pressure switch 61 reverted to off-state by closure state, and the auxiliary selenoid relay normally open point 82 and the time relay normal battle 91 reverts to off-state by closure state.
81 meetings just revert to off-state after delaying a period of time because the existence of the time relay 90, electromagnetic relay are often made war; The normally closed point 91 of the time relay just is converted to off-state after also can delaying a period of time again; The delay function of the time relay 90 has guaranteed that the constant voltage water pump 60 sides quit work, and avoided constant voltage water pump 60 to start repeatedly, stop when signal that constant voltage water pump 60 obtains reaches a safety value near the enabling signal marginal value.After signal disconnected, constant voltage water pump 60 quit work, and dynamic recorder 70 countings once; After moving in circles, can obtain the number of run of constant voltage water pump 60 and the dynamic statistics data of each run time.
Automatically write down the number of run of the constant voltage water pump 60 that obtains and the dynamic statistics data of each run time by dynamic recorder 70, fire-fighting constant pressure water supplying system provided by the invention can in time write down and monitor the duty of constant voltage water pump 60, the situation of change of leaking the water yield for accurate analyzer tube net provides the authentic data support, solves the problem that wastes time and energy of personal monitoring in the existing system simultaneously.
Though the present invention with preferred embodiment openly as above; but it is not to be used for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
