摘　　要：安康联营电站水轮机主轴密封水压在机组开、停机过程中,产生异常波动以及机组带负荷持续运行,关闭主轴密封供水水源,主轴密封水压依然超出运行要求,经过分析原因,研究出切实可行的解决方法,最终保证了主轴密封水压工作正常。In Ankang Joint Hydropower Station,the hydraulic pressure on the main shaft sealing of the turbine abnormally fluctuates and the unit with load operates continuously during the unit start and stop. After water supply to the main shaft sealing is closed,the hydraulic pressure of the main shaft sealing still exceeds the required one. Through the cause analysis,a feasible and practical solution is found to secure the normal hydraulic pressure of the main shaft sealing.
