Abstract:

Abstract: In steam turbine overhaul duration, the steam seal clearance was measured by medical rubberized fabric or lead wire,and the problems existed in the two methods were introduced. The features of the dummy shaft measuring method and the regulus lead measuring method were analyzed,and the application of these two methods was analyzed with examples.To adopt the two methods can avoid rubbing fault between rotor and steam seal and weaken bearing bush vibration during unit startup and operation after overhaul, and the unit efficiency can be improved.
