柳林县薛家坪村二级泵站设计

The design of the second stage pump station in Xue Jiaping village of Liu Lin county

为了充分发挥泵站工程在农田灌溉中的作用,根据"蓄、引、提相结合,机、电、水合理匹配,排灌、供水、发电多功能综合利用,大、中、小站合理布局"的规划原则,运用泵站工程设计原理,选定了4台SLOW250-610×2AT型双级双吸离心泵,得出了:水泵安装高程为856.0m,水泵运行工作点对应的扬程为210.00m,对应流量为340.0L·s-1,压力管路壁厚为18mm,确定了泵房和进出水池的布置型式及尺寸。

In order to exert the function of pumping station project in the irrigation,according to the planning principles,which were the combination of storage、guide and lift,the reasonable matching of engine、electricity and water,the multi-functional comprehensive utilizations of irrigation and drainage、water supply and power generation as well as the rational distribution of large stations、middle stations and little stations,by using the principle of the pumping station project design,we selected four SLOW250-610×2AT Double Double suction centrifugal pumps,and obtained the pump installation height of 856.0meters、pump working point corresponding to the head of 210.00meters、the flow rate of 340.0L·s-1 and pressure pipe wall thickness of 18 mm.The pump room and in and out of pool＇s type and size were also determined.
