燃气轮机的运维的主要作用是对当前的燃气轮机的工作状况进行监视，及时发现各种故障情况，内窥镜可通过检查孔进行快速检测，在电厂、整机厂有着广泛的应用。
The main function of gas turbine operation and maintenance is to monitor the working condition of the current gas turbine and find out various faults in time. The endoscope can quickly detect through the inspection hole, which is widely used in power plants and whole machine plants.
工业内窥镜可用于对燃气轮机的压气机、燃烧室、透平（涡轮）等部件进行非破坏性的目视检测。造成燃气轮机叶片和热通道损坏主要有腐蚀、疲劳、异物撞击等几个方面的原因，因此工业内窥镜检查的内容主要有以下几个方面：
Industrial endoscope can be used for non-destructive visual inspection of gas turbine compressor, combustion chamber, turbine (turbine) and other components. The damage of gas turbine blade and hot channel is mainly caused by corrosion, fatigue, foreign body impact and so on
压气机：叶片断裂、积灰、腐蚀 、顶部间隙变化、叶片尾缘和静叶根部锈蚀，以及异物造成的损坏。
Compressor: blade fracture, ash deposition, corrosion, top clearance change, blade trailing edge and static blade root corrosion, and damage caused by foreign matters.
燃烧室：燃烧室与过渡段的烧穿、烧裂、掉块、积碳、裂纹、金属缺损、热腐蚀、装配连接状况。
Combustion chamber: burn through, crack, block falling, carbon deposition, crack, metal defect, hot corrosion, assembly and connection condition of combustion chamber and transition section.
涡轮：腐蚀、堵塞 、裂纹、弯曲变形、凹坑、掉块、烧蚀、金属缺损、锈蚀、局部变形、异物撞击、结垢和表面涂层状况。
Turbine: corrosion, blockage, crack, bending deformation, pit, block falling, ablation, metal defect, corrosion, local deformation, foreign body impact, scaling and surface coating condition.
三维测量工业内窥镜还可以用于缺陷的精 确测量。
Three dimensional measurement industrial endoscope can also be used for accurate measurement of defects.
