摘要
与阀门控制法供水系统进行对比,分析了变频调速供水系统在节能、消除水锤效应、恒压运行等方面的优点,阐述了变频器与PLC及PID控制器等自动化元件结合实现的变频自动恒压供水系统的工作原理。
Compared with valve controlled water supply system,this paper makes an analysis on advantage of FC speed adjusted water supply system on the aspects of energy saving,water-hammer effect avoiding and constant pressure operation,and demonstrate the operating principle of FC automatic pressure constant water supply which combined frequency converter with automatic components such as PLC and PTD controller.
