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、经济和社会效益 The size and shape of the inflow channel directly affect the velocity distribution and pressure distribution of the inlet section of the pump impeller, which has a great influence on the performance of the pump device. The model test research shows that the design parameters are optimized to solve the design problem of the lateral pressurized water inlet of pump station. The first time, the elbow inlet is applied to the medium axial flow pump station , Providing a more uniform flow velocity and pressure distribution for the pump impeller, eliminating the vibration hazard of the pumping station and achieving tremendous engineering, economic and social benefits
