Abstract :
An automatic constant pressure closed-loop water supply and monitor system of small, secondary pressure waterworks, which composed of Siemens S7-300 PLC, WinCC and ABB frequency converter, is presented. The principle and construction as well as characteristics of the system are introduced also. The function, the stability and the reliability of the water supply system has been improved. The super-harmonic oscillation and labour intensity of workers is reduced. The purpose of saving energy and reducing consumption has been realized. The necessary support conditions have been provided for the entire production management information system.
