Course Overview
The descriptions within
this Learning-Doc concentrate on the lube oil system found on units that have
(or originally had) the Mk-II EHC systems. Discussion will include the
oil tank construction / major components, the motor driven oil pumps, oil
coolers, the main shaft driven oil pump, oil control valves, operating
sequences (on turning gear, during start up, on-line, shutdowns), bearing
header piping, periodic testing, and instrumentation. For each typical
