压缩机活塞杆断裂分析及预防

Failure Analysis and Prevention for the Compressor Piston Rods

通过某压缩机断裂活塞杆材料成分、宏观和微观断口、力学性能、金相组织等分析，确定了其断裂的模式为疲劳断裂，找到了造成断裂的主要原因和影响断裂的各种因素。

The chemical composition of the material, fractures, machanical properties, microstructure of the piston rods of the compressor have been studied The fatigue fracture mode is determinedThe main cause and effect factors of fracture on piston rods are found The prevention measures are proposed
