| Abstract: | Aiming at excessive bearing vibration in startup of 300 MW steam turbine generators,the paper analyzes data of bear vibration and pad vibration and tests the vibration difference between bedplates at turbine end.It is believed that the deficient connection rigidity is the major reason for excessive bearing and pad vibration in generators.The abnormal bearing and pad vibration is handled by improvement of connection rigidity. |
