摘要

某台300 MW汽轮发电机组因异常振动而导致无法正常起动

根据测试情况对出现异常振动原因进行了分析

认为国产300 MW汽轮发电机起动过程中的异常振动是由密封瓦与转子径向碰磨引起

并提出了控制措施。采取适当的运行措施

可将振动控制在允许范围。

Abstract

One 300 MW turbo-generator set can’t be normally started up owing to its abnormal vibration.Through field test

the mechanism of appeared abnormal vibration trouble has been analysed

and some measures for controlling the abnormal vibration being put forward.Result of analysis shows that the abnormal vibration of home made 300 MW turbo-generator set in the start-up process to be resulted from radial impact-rubbing of the sealed bearing shoe with the rotor.The said vibration can be controlled to an allowable range by adpoting suitable operation measures.
