高扬程水泵站初扬水充水系统的设计

高扬程水泵站在初次投入运行时对出水系统需要充水。针对充水系统运行扬程变幅大，运行条件恶劣，但使用时间短，系统利用率较低的特点，从充水方案的确定，充水设备的选择及运行等方面作了分析研究。山西省万家寨引黄工程水泵站的初扬水充水系统的设计和运行情况实践，可供今后其他工程设计参考。

Design of the pre-filling water system for high lift pump stations

The water outlet system of high lift pump station has to be pre filled water before it is put into initial commissioning. This article explains in detail the research results on alternative establishing about filling water system, selection and operation about equipment, specially for large variation range of operating lift, the worst operating conditions, the short time use, and lower utility factor etc. More experience, relative to design and operation of pre filling water system in the Wanjiazhai Water Diversion Project from the Yellow River in Shanxi Province, could be available for reference to other projects in the future.
