| Abstract: | The article describes the transient transverse vibration caused by the No.1 bearings of steam(turbine) in Huaneng Shantou Power Plant,analyzes the vibration reason and concludes that the vibration is(derived) from transient transverse vibration of the support system in steam turbine and condenser and the signal enlarging from on-line vibration measured instrument due to the pressure fluctuation of the condenser cooling water.It also gives the measures to prevent the transient transverse vibration occurred in turbine bearings. |
