摘要
恒压供水是自来水生产流程中的重要环节,本文采用西门子S7-200 CPU224为主控制器,组建自动恒压变频供水系统,阐述了系统控制过程的工作原理。
To keep pressure constant of water supply plays an indispensible part in the process of water manufactory. The basic working principle ot the control system has been introduced based on Siemens S7-200 CPU224, thus constructing an automatic fre- quency control system.
