摘　　要：检修排水系统排水能力以及排水方式的选择直接影响检修整体进度,介绍金沙江某大型电站检修排水系统的排水方式、结构特点,根据设计参数,重新对检修排水系统排水量、排水泵排水量校核,检修排水廊道、蜗壳及尾水盘型阀排水能力核算。为检修排水泵选型、排水盘型阀选型、排水方式的选择等提供理论支撑。The drainage capacity of overhaul drainage system and the selection of drainage mode directly affect the overall overhaul progress. This paper describes the drainage mode and structural features of overhaul and drainage system of a large power plant in Jinshajiang River. According to the design parameters, this paper rechecks the drainage of overhaul drainage system and drainage pump, and checks the drainage capacity of overhaul drainage gallery, spiral case and tailwater disc valve. It provides theoretical support for selection of overhaul drainage pump, drainage disc valve and drainage mode.
