学校恒压供水系统的设计与应用

The design and application of school's constant pressure water supply system

PLC和变频器的配合,能够很好地解决恒压供水问题。本文的核心是在保留学校现有水塔水位控制供水系统的基础上,采用PLC和变频器配合对学校供水系统进行恒压改造,经过调研、设计、建设、模拟运行、正式运行等阶段,改造后的学校供水系统完全可以达到自动控制、恒压供水的要求。

The coordination between PLC and transducer can solve constant pressure water supply profitably. The paper focus on maintaining present system which controlling by water tower＇s level and adapting the coordination between PLC and transducer to transform old system. After researching, designing, construction, simulation running and formal running stages, the new system can achieve the demand of automatic controlling and constant pressure water supply.
