| Abstract: | The oiltrapped inside the central hollow steam turbine's rotor can induce abnormal vibration.In palace,it's fairly difficult to identify this kind of fault.The No.4 unit at junliangcheng power plant has a fault of oil-trapped inside the central hollow rotor in 2005.This paper introduces the vibration characters,analytical idea and basis of diagnosis of the oil-trapped inside the central hollow steam turbine's rotor,which can become references for identical faults. |
