[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the database that the utility model is represented intake pressure and flow of inlet water relation.
Fig. 3 is the structural representation of another embodiment of the utility model.
[specific embodiment]
Seeing also shown in Figure 1ly, is the structural representation of an embodiment of the utility model.It comprises water inlet pipe 1 and outlet pipe 2, and water inlet pipe 1 is provided with inlet pressure sensor 3, is used to detect the intake pressure value of water inlet pipe 1; Outlet pipe 2 is provided with outlet pressure sensor 4, is used to detect the discharge pressure value of water pipe 2.Water pipe between inlet pressure sensor 3 and the outlet pressure sensor 4 is provided with a water pump 5, the output of described inlet pressure sensor 3 and outlet pressure sensor 4 is electrically connected with a microprocessor 6 inputs respectively, the output of described microprocessor 6 is connected with the control input end of a frequency converter 7, and the output of frequency converter 7 then is electrically connected with described water pump 5.
The water inlet end of water pump 5 is provided with first valve 8 along water supply direction, and the water side is provided with first one way valve 9 and second valve 10 along water supply direction respectively, and described first valve 8, water pump 5, first one way valve 9 and second valve 10 are composed in series a water pump assembly.And water pump 5 is with in parallel with second one way valve 11 again after first and second valve 8 and 10 and first one way valve 9 are connected.The setting of its one way valve can prevent that current from swinging to.The water pump 5 and second one way valve 11 are connected in parallel and form input union end A and output union end B, are provided with a strainer 12 and an antifouling isolating valve, 13 along water supply direction between input union end A and the inlet pressure sensor 3; Be provided with a pressurize surge tank 14 between output union end B and the described outlet pressure sensor 4.
The utility model course of work is summarized as follows:
When digitlization pond pipe network Pressure-superposed water supply equipment brings into operation; this moment, discharge pressure value was less or be zero; at first detect intake pressure Pn by inlet pressure sensor 3; if intake pressure Pn is between last; under shut down between the force value; microprocessor 6 compares the setting value in intake pressure Pn and the database 15; judge; after the computing; output control signals to the control input end of frequency converter 7; again by the operation of frequency converter 7 control of pump 5; this moment if water flow less than flow of inlet water Qn; water pump 5 will speed up operation, just stops when discharge pressure reaches shutdown pressure.
As user not when water or a small amount of water, the discharge that is outlet pipe is less, water pump 5 does not just move, only depend on pressurize surge tank 14 to stablize discharge pressure and supply water on a small quantity, described pressurize surge tank 14 is a kind of barrier diaphragm-type pressurized water tanks, does not contact with outside air for closed, eliminated the secondary pollution that brings thus, owing to the direct water supply of pressurize surge tank 14, reduce the running frequency of water pump 5 simultaneously, can play energy-conservation effect.
When user's water yield increases, when the discharge pressure that outlet pressure sensor 4 detects gained is lower than certain pressure, the intake pressure Pn situation that microprocessor 6 detects according to inlet pressure sensor 3 is come control of pump 5 operations: when intake pressure Pn is higher than setup pressure value, microprocessor 6 can start by frequency converter 7 automatically controlled water pumps 5, the difference in the running between the discharge pressure of only additional intake pressure Pn of water pump 5 and setting; When intake pressure Pn is lower than setup pressure value, microprocessor 6 according to the force value of the intake pressure Pn value of the detection gained of inlet pressure sensor 3 and database 1 compare with computing after, the output control signal is given frequency converter 7, again by the operation of frequency converter 7 control of pump 5, carry out ftercompction under the negative pressure condition guaranteeing that webmaster does not produce; When intake pressure Pn equaled to shut down pressure or 0 down, water pump 5 did not move.
As the intake pressure Pn of water inlet pipe during greater than last shutdown pressure, microprocessor 6 control of pump 5 quit work and directly supply water to the user by one way valve 11 this moment; When the intake pressure Pn of water inlet pipe diminishes, and during less than certain pressure, microprocessor 6 can be by 5 operations of frequency converter 7 automatically controlled water pumps.
Again as shown in Figure 3, be the structural representation of another embodiment of the utility model.The difference of itself and the foregoing description only is to set up a water pump assembly again, and its purpose has been that two water pump assemblies are used alternatingly convenient maintenance.
In sum, the operation of water pump 5 is made concrete reaction by microprocessor 6 according to the inflow situation fully, controls by frequency converter 7 again, and its process has embodied automation and intellectuality; Because the utility model has been cancelled the anti-negative pressure device of surge tank, eliminated the secondary pollution that brings thus again; Simultaneously, the utility model member is few, and is simple in structure, volume is little, floor space is few, can be widely used in the central water supply system of highrise building, resident living sub-district, megastore etc.
