摘要
变频恒压供水系统在居民楼、大型酒店、洗浴中心等场所得到了广泛的应用,并取得了良好的运行效果和节能效果。本文介绍了一种基于PLC的变频恒压供水系统,能够根据管网压力自动调整泵的运行状态,实现压力无级连续调整,同时通过软件程序控制,水泵可以自动启停、自动控制运行频率,实现用水和供水的动态平衡,从而达到供水系统稳定和节能。
Constant pressure water supply system design based on variable frequency has been widely used in residential buildings,large hotel,bath center,and so on.Favorable run effects and energy-savings have been obtained.This paper introduces one kind of frequency conversion and constant pressure water suppy system based on the PLC.The system can automatically control pumps running status according to the pipe network pressure to realize stepless pressure adjustment.Simultaneously through software control,the waterpump may automatically start and stop,and also automatically control movement frequency,to achieve a dynamic balance of water and water supply,water supply systems so as to achieve stability and energy saving.
