| Abstract: | It introduced the principle and feature of constant pressure water supply system using variable-frequency governing system based on PLC,and discussed the switching value of the flow and frequency for the main pumps witching to the stabilize-pressure pump combine with a projeet.It proposed the method of adding a fluid meter for the main pumps not switching into the stabilize-pressure pump in some case.It proved that this system had worked stable and saving energy. |
