Since putting the 2×1 060 MW nuclear power units in the first-phase project of Tianwan Nuclear Power Plant into operation
comparative large low-freency vibration is existing on the front bearing of generator due to seriously insufficient stiffness and resistance of oil film in the horizontal direction.Through reducing the elevation of bearing no.10 and decreasing the top gap of bearing no.11
effective elimination of low-frequency vibration on bearing no.11 has been obtained.
