I have problem with my Sabroe compressor Model SAB 110 having high suction pressure and low oil pressure. The starting pressure goes to 6 Bar even increased the capacity it will not lower to 4 BAR and oil pressure 5 bar - normal is 8 bars as expected. When the capacity raise to 100% the oil temperature will reach to 65C discharge goes to 85C also. I checked the suction and oil filter everything is okay.

Is there any possibility that the rotor has problem or the sliding valve?

Please give me inputs about this matter.Any help is highly appreciated
