摘　　要：海外某灯泡贯流式水电站在检修时,发现1号机组活塞缸盖与活塞缸结合面密封失效导致活塞缸盖下游侧平面漏油。为彻底消除该问题,决定对失效的密封条进行更换。受检修工期的约束,结合水电站现场实际,决定采用转轮整体不吊出机坑解体、在转轮室内水平拆装泄水锥及活塞缸盖的新工艺方案,并在该水电站1号机组成功实施。本新工艺属行业内首创,为灯泡贯流式机组避免转轮整体吊出机坑解体大修、拆装泄水锥及活塞缸盖提供新工艺方案参考。During the maintenance of an overseas bulb tubular type hydropower station,it is discovered that the sealing failure of the joint surface of the piston cylinder head and piston cylinder of Unit No.1 caused oil leakage on the downstream side of the piston cylinder head.In order to eliminate this problem,it is decided to replace the failed sealing strip.Constrained by the maintenance period and combined with the actual situation of the hydropower station,it is decided to adopt the new technological process which dismantles the runner without lifting the runner out of the hydrogenerator pit,and disassembles the drain cone and the piston cylinder head horizontally in the runner chamber.It is successfully implemented for Unit No.1 of the hydropower station.This new technological process is innovative in the industry and provides a reference for the maintenance of bulb tubular unit without being lifted out of the hydrogenerator pit for dismantling and overhaul,assembling and disassembling the drain cone and piston cylinder head.
