if power plant is running at normal condition. at that time
accidentally turning gear motor or bearing lift oil pump
came into service menas what happen to the system?
Answer Posted / devanesan
Nothing will happen. at the time of load condition also the
turning gear will be in the ON condition. it is the logic.
at this condition if the JOP gets start also nothing will
happen. only posibility is the shaft vibration may
increase. one more thing is the JOP supply is in the bottom
of the bearing. the minimum oil film also near to that
area. it may breaks the oil film and cause for bearing
failure. it will happen in the worst case.
