浅谈某水电站水轮机接力器改造可行性

Discussion on the Feasibility of Hydraulic Turbine Servomotor Transformation in Some Hydropower Station

某水电站位于重庆市石柱县,水轮机装有两套带单套管直缸接力器,机组运行一段时间后推拉杆与套管间出现漏油现象,随着运行时间延长,漏油越严重。通经分析,拟对接力器进行技术改造,采用新密封、新结构解决接力器漏油问题。

The hydropower station is located in Shizhu County,Chongqing City.The turbine is equipped with two sets of straight cylinder servomotors with single casing.After a period of operation of the unit,there is oil leakage between the push rod and the casing.With the extension of operation time,the oil leakage is more serious.After analysis,it is proposed to carry out technical transformation of the servomotor and adopt new seals and new structures to solve the oil leakage problem of the servomotor.
