摘要
对某600 MW超临界汽轮机再热主汽阀阀杆漏汽的原因进行了详细分析,并在不拆卸阀杆的情况下成功消除了漏汽现象,为处理此类问题积累了经验。
An analysis has been carried out on causes leading to steam leakage from the reheating main steam valve＇ s stem of a 600MW supercritical turbine unit, based on which the leakage problem was successfully solved without dismantling the valve stem, thus accumulating some experience for treating similar problems.
