摘要
介绍了一种基于PLC和触摸屏控制的变频恒压供水系统的构成和工作原理。系统采用变频器调速方式自动调节水泵电机的转速,以保持供水压力的恒定;在用水低谷时,投入小泵,以降低能耗。并以水城煤电集团水厂为例,详细介绍了该系统的具体实现。
The composition and operational principle of an automatic frequency conversion constant pressure water supplying system based on PLC and touch panel .The system adopts frequency conversion speed regulating measures to adjust rotating speed of water pumps, and to keep the press constant. This system can startup the little pump at the vale of using water to saving power. It also introduced in detail the realization based on the Water Factory of YongCheng Mining（Group）Co. ,Ltd.
