摘　　要：进水流道尺寸和形状直接影响水泵叶轮进口断面的流速分布和压力分布，对水泵装置的性能影响很大。模型试验研究表明，优化设计参数，解决了泵站侧向有压进水流道的设计问题，第１次把肘形进水流道应用于长距离有压涵管侧向进水的中型轴流泵站，为水泵叶轮提供了较均匀的流速和压力分布，消除了泵站的振动危害，取得了巨大的工程。An inlet passage is one conveying water from the intake pool to the pump propeller. Its size and shape will not only affect directly the velocity and pressure distribution in the inlet cross section of the propeller, but also the performance of pumping set. This paper, by means of model test and optimization of design parameters, successfully solved the problem of pressured inlet passage design and put it into application of side intake pumping stations with long distance pressured culvert inlet. The research results have supplied the pump propeller with relatively uniform velocity and pressure distribution, eliminated the hazard of vibration and achieved great engineering, economic and social benifits.
