摘　　要：针对一种水轮机在高原恶劣水质条件下使用中出现的原设计中导轴承和密封不能满足实际工作要求的不足之处。在研究了水轮机导轴承和主轴密封的工作机理后,有针对性的在基本不改变原有水轮机结构基础上提出了新的三片式导轴承和新的主轴密封改设计方案,并应用于实际的水电站改造中,取得良好的实际应用效果。To overcome the shortcomings of guide bearing and seal installed in a hydraulic turbine main shaft in foul water on plateau area, a new improvement design is put forward in this paper almost without modifying the structure of the original hydraulic turbine on a new three-leaf style guide bearing and a new shaft＇s seal after researching the work principle of hydraulic turbine main shaft＇s guide bearing and seal. The new design is used in a real hydropower station＇s improvement project and a satisfactory result is got. in its practical application.
