摘要
介绍应用ＰＬＣ与变频调速器对楼群供水系统实现恒压控制，并对各泵组的切换进行最佳匹配，实际使用表明，该系统水压恒定，操作方便，安全可靠。
Introduces a building water supply system in which the inverter and PLC is used to realize the constant pressure of the water.The system can switch between pumps to maintain optimum match.The results show that the system operates easily and reliably and the water pressure controlled is very stable.
