无锡太湖新城大溪港排涝泵站结构型式选择

Type Selection of Daxigang Drainage Pumping Station Structure in Wuxi Taihu New City

结合无锡太湖新城大溪港排涝泵站选型,介绍了城市低扬程大流量泵站的设计思路,详细分析了常用立式轴流机组、新型竖井贯流机组泵站的结构型式,并进行了经济技术比较。竖井贯流泵装置作为一种新的低扬程水泵装置形式,与立式机组相比,具有装置效率较高、设备安装检修方便、土建结构简单、工程投资省等优点,可在低扬程及特低扬程大流量城市排涝泵站推广使用。

Combined with the type selection of the Daxigang drainage pumping station in Wuxi Taihu New City, design ideas of large flow and low lift pumping station were introduced. The structures of vertical axial flow pumping station and shaft tubular pumping station were analyzed and compared. As a new low lift pump, the shaft tubular pump has an advantage over the vertical axial flow pump in terms of efficiency, installation and maintenance, civil structure and project investment. It is worthy of populariza- tion and application in low lift pumping station.
