摘要
三峡水电站于2009年全部完工,许多设备已经运行多年,进入维修周期。每年维修期间会更换大量的密封件,一些液压设备在设计时密封件的沟槽采用了非标结构,且后期维修更换密封件时许多设备不能完全拆解,导致原结构的密封件无法安装。针对其特殊的沟槽形式、工况条件以及安装要求,研制出多种结构的剖分式密封产品。经三峡水电站多套设备的使用结果表明,该类产品完全满足使用要求。
Three Gorges Hydropower Station has fully completed in 2009,many devices have been running for many years,into the maintenance cycle.A large number of seals will be replaced during the maintenance period each year,some seal groove used non-standard structure when hydraulic equipment was designed,and many devices can＇t be completely disassembled when post-maintenance and replacing seals,leading to the original structure of the seal can＇t be installed.Consider of their particular form of grooves,working conditions and installation requirements,we developed split seals with a variety of structures.The using results of much equipment in Three Gorges Hydropower Station show that these products fully meet the requirements.
