Good Evening to all experts,
Dear CSA, as you know lift oil pump just running in startup of gas turbine and if power plant continuously running in production mode , we cant able to test run 88QB lift oil pump.
previously we just did trial run after any mechanical outage like( CI AND HGPI ).
we face problem in one unit thrice that after shutdown when turbine reach turning gear speed lift oil pump again and again changeover .
you know turning gear is very very important after shutdown and some time we haven't any maintenance team in night shift.
so what you advice what we can do to not face this trouble and this key equipment for turning gear.
is this normal when turbine running on base load and we can run 88QB for trial run. is this have any effects on vibration?
