某引水工程拟建泵站的必要性及前池流场模拟

Necessary analysis of pumping station and Simulation of flow field in front of a pumping station

通过对渠首枢纽泵站建设的必要性进行分析,认为在适宜地点兴建泵站是十分必要的,并对泵站前池流态进行了数值模拟,在前池弯道设置了3座弧型导流墙,使得前池水流基本无回旋,流速分布均匀度较高,该设计方案是可行的。该项目实施后可以有效提高渠首枢纽工程的取水能力,有力保证城市和下游灌区的用水安全。

This paper through the analysis of the necessity of headwork pumping station construction, construction of pumping stations in the appropriate location is very necessary, and the pump station flow pattern was simulated. The different lengths of the three arc guide wall is arranged in the pool before the bend, makes the front pool water without swing, velocity distribution uniformity is high, the design scheme is feasible. After the implementation of the project, the water intake capacity of the canal head project can be effectively improved, and the water security of the urban and downstream irrigation districts can be ensured.
