泵站水泵汽蚀损坏原因及措施

Causes and Measures of Pump Cavitation Damage in Pumping Station

随着水利工程投资和建设水平的不断提高,水泵在水利工程中的应用越来越广泛。然而,在实践中泵站水泵汽蚀仍然是一种常见现象,这不仅对泵的使用寿命和生产率有很大影响,而且还增加了运行成本。在水泵安装和使用时,必须了解设备的性能,正确操作和维护,以使水泵正常运行,延长设备的使用寿命。景电工程为高水头多级引水工程,分多级泵站直接从黄河取水。供水过程中的所有泥沙都经过各级泵站。机组能耗增加,甚至报废,大大缩短水泵的使用寿命。针对这一问题,探讨了水泵汽蚀磨损的原因及消除方法。

with the continuous improvement of hydraulic engineering investment and construction level,pumps are more and more widely used in water hydraulic engineering.However,in practice pump cavitation is still a common phenomenon,which not only has a great impact on the pump life and productivity,but also increased operating costs.In the installation and use of pumps,it is necessary to understand the performance of equipment,correct operation and maintenance,in order to make the normal operation of pumps,extend the service life of equipment.Jingdian project is a multi-stage water diversion project with high water head.The multi-stage pumping station takes water directly from the Yellow River.All the sediment in the water supply passes through the various pumping stations.The unit energy consumption increases,even scrap,greatly shortening the service life of the pump.In view of this problem,the causes and elimination methods of cavitation wear of water pump are discussed.
