变频恒压供水技术的实际应用

Practical application of frequency constant pressure water supply technology

文章叙述了某污水处理厂利用恒压供水的方法对该厂两台水泵进行节能改造。利用S7-200、变频器、PID控制实现了此次节能改造;降低了该厂的生产成本,达到了节能降耗的目的。

This paper introduces sewage treatment plant using the method of constant pressure water supply plant two water pump to energy saving trans- formation. Using S7 - 200, inverter, PID control realized the energy saving transformation, Reduced the cost of production, achieve the energy conserva- tion purposes.
