| 摘 要： | 对湛江发电厂1号机4号轴瓦振动大的问题进行分析,认为其主要原因为:低压缸变形大导致动静碰摩,轴承座及盘车箱下部脱空引起刚度降低,轴承座的固有频率与工频相近等。对此,采取了相应的处理措施,实施后4号轴瓦振动得到有效解决。

| Abstract: | The serious vibration existing on bearing shoe no.4 of unit no.1 in Zhanjiang Power Plant has been analysed,and it is believed that the main causes to be as follows:(1)large deformation of the lowpressure cylinder leading to collision and friction between moving and stationary parts;(2)the vacant space under bearing pedestal and turninggear box bringing on lower rigidity;(3) the natural frequency of bearing pedestal is closing to the power frequency etc..For these,corresponding treatment measures have been taken.After implementation of said measures,the problem of vibration on bearing shoe no.4 has been effectively resolved,the experience providing reference for vibration diagnosis and treatment of similar type units. |
