摘要
介绍了典型的一用一备机组管路系统及其工作原理。分析了系统中各组件随外界供水量变化的运行逻辑关系,解决了进口负压水泵的脱水空转、进口倒灌水泵浸泡锈蚀两个问题。
A parallel connection system of pump units pipeline system and working principle are presented.The working logic relation of each section has been analyzed with the changing of outer water supply. Some questionscan be solved by this system, for example, pumps racing when the pressure of inlet is negative, pumps erodingwhen the rotating parts was stationary if the pressure of inlet is positive.
