Detection and Failure Analysis of Turbine Broken Blades
In the process of steam turbine running,it is often faced with various faults and accidents,in which the problems caused by the damage of steam turbine blades occupy the main part.In particular,the tur-bine blade fracture is considered to be a very harmful and common fault,which has a serious impact on the opera-tion of the unit,a series of physical and chemical tests,including detailed analysis of chemical composition,ma-terial organization,inclusion and mechanical properties,are required to fully understand the cause of fracture.In this paper,the fault detection and failure analysis of steam turbine blade,according to the detection results can understand the fracture failure mode,so as to ensure that the steam turbine can be efficient and reliable opera-tion,at the same time to ensure the safety of personnel and equipment.
