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 selection of Daxi Port drainage pump station in Wuxi Taihu New City, the design idea of urban low-lift high-flow pumping station was introduced. The structure types of common vertical axial flow unit and new vertical shaft flow unit pumping station were analyzed in detail Economic and technological comparison. As a new type of low-lift pump device, the vertical tubular pump device has the advantages of high device efficiency, convenient installation and maintenance of equipment, simple structure of civil engineering and project investment compared with the vertical type. Low-lift high-flow urban drainage pump station to promote the use.
