摘　　要：灯泡贯流式水轮机受其结构形式的影响,机组安全可靠性低,主轴工作密封容易发生事故,如何提高机组主轴工作密封的可靠性对电站的安全运行有着非常重要的意义。通过分析双岭水电站主轴工作密封的结构特点,存在的问题及改造措施,取得了较好的效果,为今后的灯泡贯流水轮发电机组的设计、制造、运行及检修工作提供了经验。The reliability of bulb turbine is low because of its structure and its working seal of main shaft is easy to happen accident. It is very important for the safe operation of the station to enhance the reliabihty of the working seal of main shaft. This paper, based on the analysis of the structure characteristics, the existed problems of working seal of main shaft of the Shuangling hydropower station, puts forward some improvement measures. The practice showed that it gained good effectiveness. These will provide some reference experience for the design, manufacturing, operation and check of the bulb hydro-generating unit in future.
