送水泵站设计 （） 摘 要 泵站是为水提供势能和压能，解决无自流条件下的排灌、供水和水资源调配问题的唯一动力来源，是解决洪涝灾害、干旱缺水的重要工程措施和实现水利现代化的重要标志之一。送水泵站也称为二级泵站，其作用是净水构筑物净化后的水输送给千家万户。 本设计主要是送水泵站，根据设计资料，通过流量和扬程，反复分析比较，参考水泵型谱图，最终选择300S58型水泵五台，四台工作，一台备用。由钢管水力计算表，吸水管管径选择D=500mm，压水管管径选择D=400mm，输水干管D=600mm。根据清水池最低水位标高和水泵HS的条件，确定泵房为矩形半地下式。水泵机组采用单排横向排列形式布置泵房左端设一进出设备的大门，控制室、配电室、值班室设在泵房右侧地上一层。水泵间距2.5m，水泵与配电设备间距2.5m，水泵距大门口7.0m；水泵距吸水管侧墙2.0m； 泵房长21.0m，宽7m，高6.0m；清水池长11.0m，宽2.6m，高7.0m；将吸水井长度确定为12m，吸水井宽度最终调整为2.7m，吸水井高度为2.8m。关键词 送水泵站；参数；泵房；辅助设备；设计计算； Design of water pump station （） Abstract Pump station is to provide potential energy water and energy, under no-flow conditions of irrigation and drainage, water supply and water resource allocation problem in single power source. Pump station is to address important measures of floods, droughts and water shortages and realizing water conservancy modernization of one of the important symbols. Also known as the second-stage pumping station of water pumping station, water purification structures whose role is to purify water after being administered to millions of households. This design is mainly a water pump station, according to the design data through the flow and lift, repeated analysis and comparison, refer to the pump-spectra before choosing the type 300S58 pumps five. Hydraulic calculation of pipe form, select D=500mm suction pipe diameter, pipe diameter selection D=400mm, water pipe D=7600mm. Under the pool minimum water level elevation and water pump HS conditions to determine whether the pump room is rectangular half-underground. Pumps with single row of transverse arrangement features pumping stations left one in and out of the door, control room, switch room, call room located in the right side of the pumping station on the ground floor. Water pump 2.5m interval, water pumps and power distribution unit spacing 2.5m, pumps from the gate of 7.0m side wall of water pump from the suction pipe 2.0m. Pumping station 21.0m, width 7m, high6.0m, and clear water ponds 11.0m, width 2.6
