Hello people. Hope someone can clarify some doubts I have about the operation of the oil reservoir in a parallel compressor rack.
From what I can see in this rack, the oil reservoir is located between the oil separator (high side) and crankcase oil level controls (low side). According to the rack īs manufacturer manual, return oil system is always kept at a pressure slighty higher than that in the compressors crankcases in order to keep the oil flowing from the reservoir into the compressors. But how can this be? Whenever the oil separator float valve cracks open, the pressure in the reservoir, connecting piping and oil level controls must be the same as the high side, correct? Does this high pressure ever reaches the crankcase or suction manifold? Any comments appreciated.
