Hi everyone,
At our site we have a GE9FA gas turbine and V94.2 Siemens gas turbine. I observed that when the temperature of the Lube oil increases the level in the Lube Oil tank decreases. Which according to me just does not fit in.
I took the example of oil inside a 200ml container. At 15 degC it will be approx. 150ml but if you heat the same container it comes back to 200ml. This is what it should happen with the lube oil tank.
But in my case, For 9FA machine the lube oil tank level (with one seal oil pump running) at 30 degC the level is 410mm of water.
As the temperature raised to 44 degC (with the same pump running) the level dropped to 389mm of water.
I checked for leakages at all the places but there were no leakages.
Kindly, give me vivid reply
