摘要
This article designs one constant pressure water supply system based on PLC. In this system, PLC and frequency converter is the main control system. Moreover, the water-supply system with a variable frequency and constant pressure is based on PCL and combines with water supply pump, pressure gage and other equipment. Water supply system realizes the water supply of constant pressure and variable flow.
