Process oil accumlation on the last stages of a centrifugal Comp.

We have 8 stages mitsubishi centrifugal compressor. The oil level rises with the increase in the stage. The impellers are in the same direction they are not back to back. The section and the discharge are from the top of the compressor. Our question is , why the oil appears mostly in the last stages?

The last stage works in very high temp, so it depends of which brand of oil you are using,because mineral oil evaporate in high temp

The oil pressure is low at idle and rises with higher engine revs. Oil levels are ok, new oil approx 2000kms ago. Was a slight noise at one stage in the engine but went away after engine's revs in


It sounds as if the clearance that the bearings normally run in have been surpassed and need to be replaced. Higher engine revs will supply extra oil which will overcome any small discrepencies but constant running at this stage will result in faster degradation of all engine components concerned resulting in a more expensive repair. Shes basically worn out.

A/c compressor lock up and leaking oil from the rear of the a/c comp. not cooling well unless driving at 1500-200 rpms.


If compressor is leaking,so is the refrigerant. A new , used,or rebuilt would be your oly option at this stage. Sorry.

Compressor not cycling and building pressure after servicing


Hi

I suspect you may have either overfilled the sump or used the wrong viscosity oil, may have splashed up onto valves and patially jammed one open.
