中文摘要: 介绍一起单轴燃气蒸汽联合循环机组停机至二阶临界转速时轴振异常案例,借助频谱分析和诊断,通过改变运行工况、设备检查修理等方式探索故障处理临时措施和根治方案,并分析总结故障产生的根本原因,为类似故障处理积累经验。
Abstract:This paper introduces an abnormal case of shaft vibration when a single-shaft gas-steam combined cycle unit shuts down to the second-order critical speed. With the help of frequency spectrum analysis and diagnosis, temporary measures and fundamental solutions for fault processing are explored by operation condition adjustment, equipment inspection and repair. In addition, analysis is also given on the root cause of the farlure, which helps to accumulate experience on similar problems.
