High - rise residential water supply pump frequency control principle and operation

[Asia Pump Network News] Frequency conversion water pump in the water supply plays a very important role, to the high-level households has brought a lot of convenience. Now to introduce high-rise residential water supply pump frequency control principle and operation. First, the high-rise residential water supply pump frequency control principle Variable frequency speed control to achieve constant pressure water supply, compared with the use of regulating valve to achieve constant pressure water supply, the energy saving effect is very significant (calculated according to the specific circumstances). The advantages are: 1, start the balance, the starting current can be limited to less than the rated current, thus avoiding the impact on the grid when starting; 2, due to reduced average pump speed, which can extend the service life of pumps and valves; 3 , You can eliminate the water hammer effect when starting and stopping. Second, the use of high-rise residential water pump 1, start equipment installation is complete, the power supply (AC 380 volts) access control cabinet, the cabinet circuit breakers and brakes. Through the control panel to select the control mode, the pumping station control system starts to run. 2, manual, stop, automatic state selection Users can determine the actual work according to their own pump control.
