摘　　要：为了有效提取出掩盖在滚动轴承振动中的加速度冲击信号,提出了运用尖峰能量技术进行振动数据分析,并通过介绍滚动轴承故障发展4个阶段下尖峰能量幅值和尖峰能量图谱的不同,从而判断轴承故障特征。结合某厂装置实际检修情况,通过选用振动烈度、加速度有效峰值、尖峰能量幅值、尖峰能量频谱图及gIE趋势图对100AYⅡ120×2型悬壁式离心泵进行了故障分析,准确地评估出轴承故障原因是滚动轴承保持架发生故障,可有效地指导人员制定相应的维修计划,降低催修成本。In order to extract the acceleration shock signal in the vibration of rolling bearing effectively,the vibration data analysis of using the technique of peak energy is proposed,and by introducing the different of the peak energy amplitude and peak energy spectrum in the four stages of fault development of rolling bearing,as to judge the characteristics of bearing fault.Combined with the actual maintenance of a plant unit,the fault analysis of 100 AY II 120 ×2centrifugal pump is carried out by using the vibration intensity,the effective peak of acceleration,the peak energy amplitude,the peak energy spectrum diagram and the gIE trend chart,so it can assess the causes of fault bearing accurately and guide the staff to formulate the corresponding maintenance plan.
