| Abstract: | The treatment process of the five times oil-whip malfunction of an import 330 MW steam turbine generator since 1997 is introduced.The mechanism of the generator to produce 16Hz low frequency vibration is analyzed.It is considered that the main caus- es of the oil-whip of this unit is the overproof gap between the bearing shells and the light load of them. |
