摘　　要：排海泵站和防潮闸是城市河道入海口的重要防洪基础设施。现以天津市某排海泵站工程设计为例,详细介绍泵站功能和运行模式。该泵站设计流量25 m3/s,合理设置6台大泵和2台小泵,对水泵实行合理控制,以降低能耗。同时,充分结合排入港池为不规则半日潮型,每天有两个低潮位,该泵站单独设置了自流通道,有效利用城市河道水位和外排港池高低潮位的水位差,实现河道自排或者水泵强排,达到节能运行的效果。此工程实例可为类似泵站提供一定的借鉴。Drainage pumping station and tidal sluice are the important flood control infrastructures of urban river entrance.Taking the engineering design of a drainage pumping station in Tianjin as an example,the function and operation mode of the pumping station are introduced in detail.The design flow of this pumping station is 25 m3/s,and six large pumps and two small pumps are reasonably set.The pumps are reasonably controlled to reduce the energy consumption.At the same time,fully combined with the drainage-into tank as irregular semidiurnal tide type,there are two low tide levels every day,the pumping station is installed of separate self-flow channels to effectively use the water level difference between the urban river level and the high and low tide levels of the external discharge tanks in order to realize the river self-discharge or pump strong discharge and to achieve the effect of energy-saving operation.This engineering example can provide some references for similar pumping stations.
