泵体汽蚀机理分析及处理

Analysis and Treatment of Pump Cavitation Mechanism

在城镇生活供水系统中离不开水泵,但水泵的汽蚀现象对生活饮用水安全影响甚大,对民生稳定极其不利。文章以某供水公司水泵产生汽蚀的原因进行了详细分析,并通过不同的方案进行对比,确定该供水公司避免水泵产生汽蚀的优化方案。通过方案对比,较好地解决了水泵的汽蚀问题,为该公司的泵房改造及水泵机组设计提供参考。

As water pump is an indispensable part of the urban water supply system, its cavitation will do harm to the safety of drinking water and to the people＇s livelihood. This paper studies the causes of water pump cavitation in a water supply company and determines an optimization scheme against the problem through comparison of different schemes, providing reference for pumping station renovation and pump unit design in the company.
