摘　　要：水轮机水压式端面工作密封通常受水头、水压、机组运行负荷的影响,密封效果不尽相同,而且随着运行年限的增加,机组磨损会造成漏水加剧,甚至会出现水淹机坑、导轴承进水等事故,对水压式端面工作密封的本体结构进行分析,探究水压式工作密封失效的原因,并提出相应的改造措施。Turbine hydraulic pile end face seal is usually under the influence of water head,water pressure,unit operation load,so the sealing effect is not the same,and along with the increase of operating time,unit wear will cause leakage,even the flooding of the machine pit and the water inflow of the guide bearing.The hydraulic pressure type work seal frame structure is analyzed to probe into the reason of the hydraulic pressure type work seal failure,and corresponding improvement measures are put forward.
