摘要
介绍了汽轮发电机组油膜振荡产生的机理以及振动信号的特征,并结合现场启机过程中发生油膜振荡的情况,给出了现场油膜振荡故障振动特征信号及诊断处理方法。
This paper introduces the mechanism of the oil-film oscillation and the vibration signal characteristics for a steam turbine-generator unit, combined with the actual data in the starting process, gathering up on-site the signal characteristics of the oil-film oscillation fault vibration and diagnosis methods.
