摘　　要：望虞河是太湖流域北排长江的重要通道,多年实测水文资料表明,在望虞河进行排水调度时,启用泵站排水的机会占比可达总排水时间的25.9%,这表明望虞河沿江泵站在流域防洪体系中发挥着重要作用。结合水泵特性曲线计算表明,望虞河沿江泵站现状设计扬程(2.5 m)较实际运行扬程偏高,其中泵站排水能力超出装机设计流量20.0%的运行时间占总排水时间的65.9%。依据泵站设计规范和相关地方标准,结合水文资料分析,建议将泵站设计扬程调整为1.78 m。优化后的设计扬程更符合泵站实际运行环境,同时可以减少电耗等泵站运行成本,延长泵站使用寿命,对于望虞河工程效益的发挥具有重要意义。The Wangyu River is an important watercourse connecting the Yangtze River and Taihu Lake.Relevant hydrological data shows that the pumping opportunity can account for 25.9%of the total drainage period from the Wangyu River to the Yangtze River,which indicates that the pumping station plays a crucial role in the drainage period of Taihu Basin.The current design lift(2.5 m)of the pumping station is higher than the actual operating lift,and the running time of the pumping station exceeding 20%of the installed designed capacity accounts for 65.9%of the total operation time.According to the design specifications of the pumping station and relevant local standards,combined with the analysis of the hydrological data,it is recommended to adjust the design lift of the pump station to 1.78 m in the subsequent upgrading of the pumping station.The optimized design lift is more compatible with the actual operating environment of the pumping station,and it also reduces the operating costs of the pumping station such as power consumption,and prolongs the service life of equipment,which is of great significance for the overall benefits of the Wangyu River Hydro-junction.
