本文针对包钢1~#高炉TRT发电机组检修后起车轴瓦振动超标,通过四通道时域波形的采集,利用频谱分析及有关故障诊断理论,对发电机组振动进行了分析,在发电机振动处理过程引入现场动平衡技术,最后得出引起振动主要原因是对中及松动综合影响导致发电机油膜失稳。阐述了引起油膜涡动的原因及温度对中小型发电机对中的影响。
In this paper, Baotou 1 # Blast Furnace TRT generator overhaul bearing car vibration exceeded, through the four-channel time-domain waveform acquisition, the use of spectrum analysis and fault diagnosis theory to analyze the generator set vibration, the generator vibration processing The process introduces the field balancing technology, and concludes that the main cause of the vibration is that the combined effect of neutralization and loosening causes the oil film instability of the generator. The causes of oil film whirl and the influence of temperature on the alignment of medium and small generators are expounded.
