污水泵站进水流态的分析及其改进

Analysis and Improvements of Inflow Conditions of a Sewage Pumping Station

根据上海市污水治理二期工程SA泵站水力模型试验，分析城市污水泵站前池普遍存在的不良进水流态现象及其对水泵性能的影响，提出前池流态改善措施．试验表明，改进后的前池使流态得到明显改善，水泵机组效率明显提高，并可有数降低泥沙淤积．

Based on the hydraulic model tests for the SA pumping station of Second Stage of Shanghai Sewag Project, the bad flow conditions in the forebay generally existing in sewag pumping stations and their influences upon pump efficiency are analyzed and the improvement measures are put forward. It is shown by the tests that the flow conditions in the forebay can be improved, the pumps efficiency will be increased, and the accumulation of debris can be reduced effectively by a barrier Plate.
