摘要
对大型汽轮发电机组轴系标高对振动的影响进行了分析,提出了运行中判断转子对中状态的合理方法。指出标高对振动的影响需要根据故障的性质而定,标高变化对强迫振动的影响较小,对自激振动的影响较大。
Influence of bearing elevation on vibration of large turbo generator unit is analyzed in the paper. The method to decide rotor alignment condition is given. It is pointed that influence of elevation depends on the property of fauhs. Influence of elevation on the self excited vibration is larger while it is smaller on the forced vibration.
