Energy Saving Application in Constant Pressure Water Supply System Based on SANCO - vm05 Frequency Converter

This paper analyzes the design of constant pressure water supply frequency control system based on SANCO - vm05 inverter with the built-in PID regulator and SWS water supply control. It’s replacing traditional way of water supply to eliminate the secondary pollution of water quality, improve the quality of the water supply, save energy by 20% - 40%, thus it’s proved as small investment and large gains.
