介绍了通过水工模型试验提出的引黄入晋工程总干三级泵站侧向进水前池的优化体型及为调整水流结构而采取的整流板等工程措施 ,这些措施使泵站进水前池中水流流态平稳 ,流速分布均匀 ,避免了在各种工况下前池中产生螺旋流及水面串通漏斗漩涡 ,能保证水泵安全、正常、高效运行 This paper introduces the optimized shape of the lateral inflow forebay of the general trunk pumping station of the Yellow River diversion project and the rectifying plates and other engineering measures adopted for adjusting the water flow structure proposed by the hydraulic model test. These measures make the pumping station enter the water The water flow in the front pool is stable and the flow velocity is evenly distributed, which avoids the spiral flow and the surface columnazet spiral whirlpool in the pre-tank under various operating conditions, which ensures the safe, normal and efficient operation of the pump
