万家寨引黄工程南干二级泵站正向进水矩形前池布置方案

Yellow River Project SM2 Pump Station openly into waterallocation schema

万家寨引黄入晋工程南干线二级泵站为高扬程、大流量、多机组泵站 ,且水泵吸程较大 ,因此泵站前进水系统的布置就显得极为重要 ,由于地形、来流条件、不淤流速等所限 ,形成了该站正向进流的布置方式。在经设计及水工模型试验验证的前提下 ,先后对进水系统进行了多种形式的研究论证 ,力求使进水具有良好的水流流态 ,前池内不形成漩涡 ,满足进水管淹没及所需秒换水系数要求 。

Wnajiazhai Yellow River Diversion Project SM2 Pump Station is the station of high raised order,large flow,many pumps,and has more large absorb.So that the into system of pump station will be more important.Station openly into water is owing to langform,the into water condition and the limit nor deposit speed.Early or later carry out many form research and prove to the into pool under precondition of design and hydraulic model experiment.Striving to into water has good flow condition and the into pipe has not vortex.Satisfy the require to into pipe flood and into pool second exchange water coefficient.Finally station will be assured safety running.
