汽轮机顶轴油系统改造与预防轴瓦磨损的关系

The Relationship between Retrofit of Shaft Oil System of Steam Turbine and Prevention of Bearing Friction

针对神华国能焦作电厂有限公司660MW 新机组在开机过程中造成#1～#4 轴瓦不同程度轴瓦磨损的原因进行了分析，对机组高中压缸顶轴油系统改造。本文提出改造中如何预防轴瓦磨损，用顶轴试验证明了顶轴油系统的添加效果，为新机组今后的稳定运行排除障碍。

After analyzing reasons of No.1 to 4 bearing bush abrasion caused by 660MW new units in theprocess of starting up in Shenhua Guoneng Jiaozuo Electric Plant Co.,Ltd and transform high pressure cylin?der head shaft oil system. This paper presents how to prevent bearing wear abrasion in the process of trans?forming,prove jacking oil system's add effect by taking top shaft test,which helps remove barriers for the stable operation of new unit.
