城市排水泵站侧向进水前池流态的研究

在城市排水泵站中，由于受地形、用地的限制，常采用布置紧凑的侧向进水前池．然而，侧向进水将会造成前池水流紊乱，流速分布不均，产生局部的回流、漩涡等，从而影响了水泵的效率．结合上海污水治理三期工程汶水路泵站模型试验，对侧向进水前池的流态进行研究，并提出改善不良流态的工程措施。

Research on the Hydraulic Characteristics of the Side-direction Forbay of the Urban Pumping Station

In the urban pumping stations, owing to the terrain or the limit of land use, the side-direction forbay is often adopted. But this will result in disorder of rate of fluid in forbay, uneven distribution of flow speed, partial backflow and whirlpool. Thus, the efficiency of the pump will be affected. Based on the model test on the hydraulic characteristics of the Wenshui Road Pumping Station in the Third Phase Shanghai Disposal Sewage Project, this paper has studied the flow pattern of the side-direction forbay and put forward some measures to improve the poor flow pattern.
