650MW机组汽轮机轴瓦烧蚀原因分析及处理

汽轮机轴瓦烧蚀会直接影响机组的安全稳定运行,介绍了华润电力（常熟）有限公司3×650 MW机组汽轮机轴瓦烧蚀情况,分析认为汽轮机油老化产生油泥沉积是导致轴瓦烧蚀的主要原因,通过对汽轮机油实施再生处理后,解决了油质老化、轴瓦烧蚀问题.汽轮机油品质直接影响机组的安全稳定运行,对汽轮机油的老化应引起高度的重视,提出汽轮机油日常运行维护的注意事项.

Cause Analysis and Treatment on Bearing Pad Fault of 650-MW Steam Turbines

Bearing ablation directly affects the safe operation of steam turbines.In this article the analysis on bearing ablation of three 650 MW steam turbines in China Resources Power （Changshu） Co.,Ltd.is conducted.It is concluded from the analysis that the main cause of bearing ablation is the sludge deposition generated from turbine oil aging.When the turbine oil is regenerated,the problems of oil aging and bearing ablation are solved.Since the turbine oil quality has direct effects on the safe and stable operation of the unit,more attention should be given to turbine oil aging and measures on regular operation maintenance of turbine oil are proposed.
