Abstract
When the steam turbine turning device of a power plant is put into operation
the friction phenomenon occurs between the turning gear and the large gear of the rotor
and the temperature of the turning box is as high as 130 ℃ after the barring is put into operation. The structure and principle of the type of the barring are adopted. Based on the actual situation of the on-site disintegration inspection
the causes of the rubbing failure and the high temperature of the barring box were analyzed. The problem was solved satisfactorily by modifying the starting mode of the barring and the oil system.
