空透机轴承故障与振源诊断

Fault and Vibration Source Inspection of Bearings in an Air Turbine

通过应用振动分析方法，对设备进行现场实时分析、振动测量趋势分析与ＦＦＴ动态诊断，准确判断出空透机推力轴承因振动频繁损坏的根本原因。

Real time analysis, vibration measurement trend analysis and FFT dy- namic inspection of an air turbine were carried out using vibration analysis method. Damage reasons of thrust bearings in the air turbine due to frequent vibration were exactly deter-mined.
