摘要
Abstract
For the Qingcaosha water-supply pumping station in Shanghai city, the hydraulic design of elbow inlet passage and siphon outlet conduit were completed, and the detailed model tests of pump set were selected for hydraulic model. The test system and test rules were illuminated and the detailed test results of the four hydraulic models have been obtained. The test results show that the all conditioning mixed-flow pump model is most appropriate for the pumping station. At the blade angle of -2°,the efficiency of the model pump set is more than 79.5 ％ at the net lift of 5.8 m, with a very wide operational areas of high efficiency. And the flow of the prototype pump set is 34.6 m3/s. At the net lift of 0 m that is the most adverse operating conditions, the critical NPSH is less than 10 m. So all the performance of the mixed-flow pump can meet the design requirements of the pumping station, and it can operate safely and reliably with high efficiency.关键词
