响洪甸蓄能电站主轴密封改造分析

Analyse to Principal Axis’airproof Set of Xianghongdian Pumped Storage Station

响洪甸抽水蓄能电站是我国自行设计、制造的第一座中型蓄能电站,除转轮从国外进口外,其它设备都由国内厂家生产制造。电站自2000年6月试运行以来,水泵/水轮机主轴密封装置因磨损严重而多次停机检修,影响了机组的安全稳定运行,为此,响蓄电站对两台机主轴密封进行了不断的更新改造并取得了一定的成效。这里结合主轴密封运行和检修、改造的实际情况,对改造前后主轴密封装置的工作原理和损坏的原因进行了分析,并提出改进意见。

Xianghongdian pumped storage station went into operation in June 2000.Since then,the principal axis’airproof set of pump/water turbine leaked many times due to wearing.It analyzes the principles and damage reasons of the principal axis’airproof set and puts forward renovation opinions contactting the fact of run and reform.
