摘要
本文针对恒速泵供水系统中依靠节流调节维持水压稳定的种种缺陷,为了从根本上解决系统用电效率低,供水压力波动大等疑难问题,以可编程控制器和变频器为控制中心,设计了一套变频调速恒压供水系统,该系统供水压力稳定,自动化程度高,节能效果显著,长期运行稳定可靠。
The automatic water-feed system with speed adjusted by PLC and VVVF was introduced in this paper. PLC was used to process the logical and PID control,and VVVF was used to adjust the feed water pumps＇ speed. The constant feed water pressure with highly automatic operation could be provided. The control system was energy-saving with steady work conditions.
