高炉助燃风机电机滚动轴承故障的分析与诊断

介绍了高炉助燃风机设备基本情况，针对助燃风机电机滚动轴承外圈故障的现象，根据振动分析的普通理论，应用RH802双通道数据采集器，对其信号进行时域、幅域、频谱、包络谱等进行分析和诊断。实践证明，故障诊断技术对现场设备滚动轴承故障诊断可以准确地确定故障部位，为设备维修提供科学依据。

Analysis and Diagnosis on Failure of Rolling Bearing of BF Combustion Blower Motor

BF combustion blower is roughly described in the paper.Aiming at the failure at the outer ring of rolling bearing for combustion blower motor,the author conducts analysis and diagnosis on signal time domain,amplitude domain,frequency spectrum and envelope spectrum by RH802 duel channel data collector on the common principle of vibration analysis.Practice indicates that failure diagnosis technique can accurately define the fault position of rolling bearing on site and provide scientific basis for equipment m...
