摘要
对某电厂3号燃气轮机压气机叶片的故障原因进行分析,调查了故障发生经过、运行记录、控制系统记录、机组分解现场、零部件损坏情况,对叶片材质和断口进行了理化检验分析,得出故障原因,对机组的修复和今后的安全运行具有重要的意义。故障与运行操作无直接关系。故障原因分析的结论成为电厂向制造商索赔的技术依据。
An analysis on the compressor blade failure of No. 3 gas turbine in a certain plant was analyzed. The failure occurring, operating record, control system record, unit decomposition site and components damage status were investigated. The physical and chemical inspection analysis for blade material and blade fracture were done to obtain the failure causes, which has a great significance to the rehabilitation of unit and later safe operation. The failure had no direct relation to operation. The conclusion of failure analysis could be considered as technical material used for the plant, who claimed for damages from manufacturer.
