刘刚辽宁清河发电有限责任公司,辽宁,铁岭,邮编摘要:对#9 机 600MW 汽轮发电机组调试阶段出现的多重振动问题进行了分析
介绍了该型机组轴系动平衡方案,分析了平衡中出现的一些异常现象,如瓦振过于敏感、轴振/瓦振矛盾等,讨论了发电机后轴承塑料油档摩擦以及传感器支架刚度不足引起的不稳定振动现象和原因,并对发电机前轴承出现的二倍频振动等也进行了讨论

China,Abstract: The paper researches the multiple vibrationfaults occurred in #9 turbo generator unit(600MW) during the debugging process
Shaft dynamic balance project is introduced
Abnormal vibration phenomenon during the balance process, such as excessive sensitivity of bearing vibration to unbalance force and the conflict phenomenon between shaft vibration and bearing vibration is analyzed
The paper also research
