消防泵恒压供水控制实践

Practice on constant pressure water supply of fire-fighting pumps

介绍了某电厂消防泵的恒压供水自动控制系统 ,采用PLC与变频调速结合控制 ,运行结果表明 :节能效果显著 ,系统运行稳定 ,能满足现场要求。

This paper introduces the automatic control system of fire-fighting pump's constant pressure water supply of a certain power plant. This system combines PLC with inverter speed adjusting in control and has got results of the obvious energy saving effect and stable system operation required on site.
