Good Day,
Help needed to understand high lube oil tank pressure.
We use the frame 5D gas turbines that comes equip with a mist eliminator operated by a vacuum assisted blower. On some of our units we are experiencing high lube oil tank pressure.
During the last plan downtime, we took the opportunity to change out all the filters in the mist eliminators, replace all the butterfly valves, replace the motors, inspect the blowers, and clean the dead leg piping's that goes back to the lube oil tank. In addition, all gauges were calibrated.
However upon start up the the oil tank pressure for three (3) of the units didn't change. Below list the before and after readings.<pre>
BEFORE AFTER
+12mmH20 +17mmH2O
+12mmH20 +15mmH20
+15mmH20 +20mmH20</pre>
All the other units have the oil tank pressure between -51mmH20 and -10mmH20.
CAN ANYONE SHARE SOME LIGHT ON THIS TOPIC?
