Analysis and treatment of abnormal vibration of a steam turbine of 600MW unit

Abstract

Abstract:

During the normal operation of No.2 unit in a power plant, there is unsteady intermittent vibration of steam turbine side No.2 bearing. Through the vibration data monitoring, the cause and mechanism of the abnormal vibration of the unit are analyzed. The abnormal vibration of the unit is caused by the intermittent rubbing due to the deposition carbonization on the oil battle. After cleaning the carbon deposit on the oil baffle, the vibration of the unit returns to normal.
