摘要
分析了变频器恒压供水系统的基本原理,介绍了由1台变频器进行软起动和变频驱动的设计思路和方法。由于具有专用SPFC控制宏,该系统可省去PLC控制器,简便易用,能自动保持水压恒定以满足供水要求。
The principle of VF and constant pressure water supply system were analyzed,and its soft-start and VF control through a single transducer were introduced.The system employs a special macro control instead of the PLC controller to keep a constant water pressure as required.
