摘　　要：某9E燃机因长期启停频繁而缸体变形,在冷态启动过程中发生动静碰摩,引起振动持续爬升进而跳机。介绍了该故障经过,通过跳机前后轴振数据分析,判断故障为动静碰磨,经过开缸检查、打磨叶片等处理后振动恢复正常,并制定防范措施,为类似故障问题处理提供参考。The cylinder body of a 9E gas turbine was deformed due to frequent start⁃up and shutdown for a long time,which caused dynamic and static friction and continuous vibration during cold start.Fault process,cause analysis,inspection and treatment as well as preventive measures are introduced to provide reference for similar fault trouble⁃shooting.

关 键 词：缸体变形 冷态启动 故障 振动
