| Abstract: | During the trial operation of No.1 500 MW supercritical turbine power generators produced by former Soviet Union at Yimin Power Plant, No.4 bush of the driving turbine in No.1 steam operated water pump vibrated severely, and it was confirmed through the analysis of data gathered through several tests that oil film oscillation occurred in No.1 driving turbine, and an appropriate action was therefore taken to ensure the normal operation of the driving turbine. |
