Frequency speed regulating control user 15 pressure of pipe network are constant, and dormancy is carried out in useless water.
Under small flow rate mode, as water consumption increases, auxiliary pump 11 continuously output peak load 30 seconds, first pressure are compensated
When 1 pressure value of outlet pipe that monitoring sensor 21 monitors in real time is still less than preset pressure section minimum value, control system control is mended
Repay auxiliary pump 11 to shut down, make the auxiliary pump 11 of compensation in a dormant state, motor-driven valve 13 is automatically closed under control system control, and compensation is auxiliary
11 pairs of diaphragm type steady-flow tanks 12 of pump carry out high-voltage energy storage, and energy storage pressure is higher by the specified pressure of supply water 0.1Mpa of user's pipe network 15, store up
Energy pressure reaches predetermined value, and the auxiliary pump 11 of compensation is out of service, and check-valves 14 is automatically closed, the closed energy storage of energy-storage system, in case small
Termination of pumping pressurize under flow rate mode；Simultaneity factor automatically turns on supercharging main pump 3 and is pressurized moisturizing, into common flow rate mode；According to
Second pressure monitoring sensor 22, the 3rd pressure monitoring sensor 23 pass the pressure value monitored back processing module in real time
16, analyzed and processed, according to analysis and processing result, supercharging main pump 3 starts work under control system control；First start one
Main pump 3 is pressurized, when water consumption increases, when a pump group water supply does not reach preset pressure section minimum value, control system control is opened
Second supercharging main pump 3 is moved, when more supercharging main pumps 3 work at the same time, principle and so on, until outlet pipe 1 stablizes water outlet.
The utility model overcomes shortcoming existing in the prior art, there is provided a kind of water distribution system flushing device, borrows city
The existing head potential energy of political affairs pipe network, it is effectively energy saving, small flow differential pressure compensation is being used with water low peak period, is allowing main pump to stop for a long time
