摘要

珠海发电厂2号汽轮发电机组振动较为复杂

对机组轴系、轴瓦、发电机静子、厂房6.3m层楼板等处的振动进行了全面的测试

对测试结果发现的机组振动问题及其原因进行了全面分析和推理诊断

查明故障原因有发电机转子静子与台板连接水平方向刚度不足、厂房6.3m层楼板局部共振等。对此

提出了简单、可行的消振对策。

Abstract

The vibration trouble occurred on turbo-generator set no.2 in Zhuhai Power Plant is comparatively complex.The vibration on shaft system of the unit

on bearing shoe

on stator of the generator

and on floor of 6.3 m elevation in the main building has been tested in an all-round way

the causes leading to vibration of unit being comprehensively analysed and inferentially diagnosed.It has found that the causes are:insufficient stiffness in direction of joint level between the stator of generator and the bed-plate

as well as partial resonance with the floor of 6.3 m elevation.For this

simple and feasible measures for elimination the vibration have been put forward.
