| 摘 要： | 锦州石化分公司连续重整装置的一台4M40压缩机在运行四个月后,发生了活塞杆断裂失效,为此委托中国科学院金属研究所对压缩机活塞杆的化学成分,力学性能及金相组织进行了分析,从而判断出活塞杆的失效是由于活塞内的刮油环弹簧的碎断造成活塞杆的疲劳断裂。

| Abstract: | After running 4 months, the type 4M40 compressor of the continuous catalytic reforming (CCR) unit of the Jinzhou Petrochemical Company was shut down due to fracture of the piston rod. We entrusted the Metallic Research Institute of China Science Academy with the analyses of the piston rod in terms of chemical composition, mechanical property and metal-lographic phase. Through these analyses found that the failure was caused by spring cracked of scraper ring in the piston that caused fatigue fracture to piston rod. |
