摘要
介绍了水布垭电站水轮机导叶端面密封的运行情况,针对其密封材料易空蚀磨损、检修困难等缺陷,提出了解决缺陷的方法。改进后的机组运行稳定,密封效果良好。
Current situation of the end sealing of guide vanes in hydro-turbines in Shuibuya Hydropower Station is intro-duced.It shows that the current sealing material is of certain defects such as the tendency of cavitation damage and diffi-culty of maintenance.Improvement measures are then proposed and good sealing performance is obtained.
