Compressor seal oil setting
Compressor seal oil setting
(OP)
I have some thing I would like some one to explain to me. we have a centrifugal compressor with suction pressure 150 PSI and the discharge is 560 PSI. The setting for the seal oil PDCV is 35 PSI above the suction pressure. Why the setting for the PDCV is connected with the suction pressure ? the discharge pressure is higher then the suction pressure. Why it is not connected to the discharge pressure?!





RE: Compressor seal oil setting
Review the cross-sectional drawing of your compressor and this should be evident. The reference to the seal oil differential pressure controller should connect to the balance chamber. This may be slightly higher than suction pressure.
