Abstract

Abstract: The preparatory work before overhaul, the standardized work during overhaul and the tidying work after overhaul for largecapacity steam turbine were introduced, which can cause the technicians to understand the entire process of steam turbine overhaul clearly. This is helpful to ensure the seamless connection in the overhaul process, to enhance the overhaul quality of the steam turbine and to shorten repairing time; and it is useful for safe and stable operation of the unit in longer period.

Key words: steam turbine, overhaul, delicacy management
