摘要
某装置液环泵泵轴发生断裂,通过宏观检验、硬度测试、化学成分分析、金相检验、断口分析、能谱分析等对泵轴断裂的原因进行了分析。结果表明:腐蚀和疲劳应力共同作用下造成断裂。
Rupture was occurred in the shaft in liquid ring pump used in one plant.With the methods of macro examination,chemical composition analysis,metallurgical examination,fracture analysis and energy spectrum analysis,the cause leading to the rupture was analyzed.It was shown from the result that the rupture was induced from the actions of corrosion and fatigue together.
