摘要
本文介绍了一种基于三菱FR-500系列变频器内部PID功能的PLC控制恒压供水系统,该系统较好地解决了高层建筑、工业、消防等供水需求,实行自动恒压供水,具有明显的经济效益和一定推广价值。
Based on the inner PID function of MITSUBISHI FR-500 series inverter a isobarically water supply system controlled by Programmable Logical Controller PLC is presented in this paper. With this system the water supply for multi-storied building industry fire fighting and so on can be implemented efficiently and the system features with automation and constant pressure for water supply has a distinct improvement in benefit and certain valuable to society.
