引黄工程总干三级泵站侧向进水前池水工模型试验研究

本文介绍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。

Hydraulic Model Test on Lateral Receiving Forebay For the Third-stage Pumping Station in the General Main Line of the YRDP

Based on the hydraulic model on lateral receiving forebay of the third-stage pumping station in the General Main Line of the YRDP,some proposals such as optimization of the structural form of the receiving forebay,adding of a rectification plate and so on in the receiving forebay have been offered for improving of the design.The hydraulic model test shows that after these proposals have been taken,in the receicing forebay,the flow pattern approaches to be stable,thedistribution of flow velocity comes into uniform,and there are no helicoidal flow and funnel-shaped eddy under every kinds of operating conditions.All of these proposals will be beneficial for guarantee of the safe,normal and high-efficiency operation of the pumps.
