可编程序控制器在多泵组自来水加压站上的应用

The Application of Programmable Logic Controller in Water Supply Pumping Station of Multi pump set

利用价格低廉的单板型可编程序控制器自动控制多台泵组，按时间顺序，分高、低峰用水时段，控制多台泵组的多种流量组合，实现自动加压供水，以较低的投资成本，达到泵组加变频调速加压的高效率。

Multi pump set can be controlled automatically by the low cost PLC of SB type Various conbination of flow from the multi pump set is controlled according to time sequence and the low and high pick of water consumption so that maximun efficiency is obtained with frequncy control of pumping speed for the pump set Thus auto supply of water is achieved with low cost
