淮安三站水泵是根据灯泡贯流式水轮发电机组的理论而设计的,在引用过程中有些理论不是很成熟,特别是效率理论和气蚀理论,因而在实际运行中出现严重气蚀问题。通过对水流冲角、泵站下游水位变化、进水流道水流方向、效率曲线、水质等方面的分析,找出淮安三站叶片气蚀的原因所在,并提出相应的解决办法,为今后类似的泵站设计、制造、管理运用提供参考。 Huai’an three pumps are based on bulb turbine turbine theory and design, some of the theory in the reference process is not very mature, especially the efficiency theory and cavitation theory, so in the actual operation of serious cavitation problems. By analyzing the angle of flow, the change of water level in downstream of pumping station, the flow direction of water inlet, the efficiency curve and the water quality, the reason of the cavitation erosion in the three stations of Huai’an is found out and the corresponding solutions are proposed. Pumping station design, manufacture, management and use of reference.
