摘要
针对压缩机电机轴的断裂事故进行了失效分析,通过对电机断轴的材质检测和断口形貌分析,判断出电机轴的材质不满足国标要求,造成其承载能力低,在运行过程中发生了疲劳断裂,并提出了改进材质等预防措施。
A fracture accident of a compressor＇s electromotor axes was analyzed. By means of material test and fracture appearance analysis of electromotor axes, the material of electromotor axes was confirmed to be unmatched with Chinese national standard. The electromotor axes can not bear heavy load and a fatigue frature happened during its running process. Some measures such as replacing material were proposed to prevent the electromotor axes from fracture failure.
