汽轮机组的多发、常见故障之中,汽轮机出现异常振动是较为多发、复杂、难以确定的故障之一,如果不及时加以有效的排除,则会引起整个发电机组的安全、稳定性。因此,有效分析、排除汽轮机异常振动则成为我们日常对汽轮机组保养与维护的工作重点。本文结合笔者多年的工作实践,就汽轮机异常振动出现的原因进行逐一的分析,并提出几点排除方法,仅供参考。
Turbine multiple, common faults, the turbine abnormal vibration is more frequent, complex, difficult to determine one of the faults, if not effectively eliminated, it will cause the entire generator set of safety and stability. Therefore, effective analysis and elimination of abnormal vibration of the steam turbine has become our daily focus on the maintenance and repair of steam turbines. Based on the author’s years of work practice, this article analyzes the causes of abnormal vibration of steam turbine one by one and puts forward some methods of elimination for reference purposes only.
