本文介绍一种由PLC和变频器实现的模糊恒压供水控制系统,取代了高位水塔和直接水泵加压供水方式,现场运行表明,该系统运行稳定,节能效果明显。 This paper introduces a fuzzy constant pressure water supply control system implemented by PLC and frequency converter, which replaces the high water tower and direct water pump pressurized water supply. The field operation shows that the system is stable and the energy saving effect is obvious.
