摘要
介绍600 MW汽轮发电机组调试中,主机各轴承振动的情况,分析认为轴承振动超标的原因为动静碰磨、支撑轴承的刚度变化、热不平衡等,提出有针对性的处理措施,并对处理后的效果进行评价。
This paper introduces the vibration circs tor bearings,analyzes the main causes are dynamic stator rubbing,stiffness change of sustain bearing balance,the disposal measures arc confirmed, and after disposal is evaluated.
