摘　　要：本文以三峡地下29号、30号机组水轮机接力器安装为例,介绍了接力操作导叶的工作过程及接力器的结构,详细描述了改进的水轮机接力器压紧行程调整以及复核过程。使用改进的工艺后,两接力器在28Bar油压下,两活塞几乎同时贴紧接力器缸盖,两接力器在导叶全关压紧过程中非常同步,受力均匀,增强了接力器的运行稳定性。This paper introduces turbine servomotors operating wickets and their structure, and use Three gorges underground plant Unit 29, 30 as example, especially describes the servomotor pre- stressing test and checking program. After pre-stressing test and checking test, two servomotors operate completely synchronous and with same load, which improve the servomotors＇ stability.
