溪洛渡水电站800MW级水轮机技术研究与实践

Study and practice on technology of 800 MW hydro-turbine for Xiluodu Hydropower Station

本文介绍了溪洛渡水电站800 MW级水轮机主要参数(水头、出力、稳定性指标、效率和流量、空化性能等)和主要部件结构(转轮、蜗壳和座环、导水机构、圆筒阀、主轴和主轴密封、水导轴承、补气系统和尾水管等)的设计成果。研究成果可供水电站设计和施工参考。

The design resuhs of the main parameters （water head, output, stablity index, efficiency, flow rate, cavitation per- formance, etc. ） and the main component structures （ runner, spiral case, stay ring, water distributer, cylindrical valve, main shaft and its seal, water pilot bearing, air admission system, draft tube, etc. ） of the 800 MW hydro-turbine for Xiluodu Hy- dropower Station are introduced herein, so as to provide some references both the design and the construction of the hydropower station.
