摘要

国电太原第一热电厂13号机组运行中频繁发生振动大幅波动现象

通过对振动试验数据以及机组升速过程振动记录等的全面分析

确定机组振动为摩擦振动

振动为中压转子弯曲、高压侧联轴器瓢偏过大以及轴系标高偏差过大引起动静碰磨所致。经调整运行参数和消除联轴器对轮瓢偏

振动有所改善。

Abstract

A large margin fluctuation phenomenon of vibration has frequently occurred in operation of unit no.3 at Guodian Taiyuan Thermal Power Plant.Through all-round analysis of vibration test data

as well as vibration record in the speed up process

etc.

it is determined that the vibration trouble of said unit to be rubbing vibration which was caused by bending of the IP rotor

and dipper-shaped deformation of the coupling at HP side was overlarge.as well as the deviation of shaft elevation was over-big.Through adjustment of operation parameters and elimination of the dipper-shaped deformation for disc-pair of the coupling

said vibration has been improved to some extent.
