污水泵站水力模型试验

A HYDRAULIC MODEL TEST OF A SEWAGE PUMPING STATION

上海彭越浦泵站是世界上大型污水泵站之一,其流量40m^3/s,扬程23m。 试验采用相似原理,正态模型,模型比为10,着重研究污水泵站特点、水量均匀性和水锤、泡砂及其扩散角等水力特性。通过二年试验,取得了大量数据,优化了设计。

Shanghai Peng-Yue- Pu Pumping Station is one of the large- size sewage pumping stations in the world. its flow rate amounts to 40 m3/s and pump total head 23 meters.The test is carried out by making a proportional model of one-tenth scale based on the principle of similarity. And it emphasizes the study of such hydraulic characteristics of sewage pumping station as the evenness of flow, water hammer, sand sedimentation and the divergent angle etc...Through two years of test,a large quantity of data have obtained and also optimized the designing.
