The compressor is equipped with an oil-gas separator to reduce the oil content in the exhaust gas. I would like to ask where the oil and gas in the exhaust gas come from The main issue is that I don’t understand how this oil-gas separator connects and operates with the compressor Please recommend! I hope someone who understands can explain it, thank you
It depends on what type of compressor it is; for example, in a screw compressor, the oil and gas come from the lubricating oil used in the screws. In this type of compressor, air and lubricating oil are compressed together. The lubricating oil serves to seal, lubricate, and cool the components. After compression, the lubricating oil and air are not completely separated, which results in oil being present in the gas； The oil and gas in piston compressors come from the lubricating oil inside the cylinders; when the cylinders compress gas, this oil mixes with the gas, resulting in the gas containing oil and gas.
An oil-gas separator is simply a section of pipe connected to the machine head.
I’m currently learning about this screw compressor; I haven’t had much experience with it, so I’m a bit confused. Thank you
Looking at this PID diagram, nitrogen is used for sealing; after passing through the oil-gas separator, it returns to the compressor. But where exactly does it return to within the compressor? Also, does both the primary intake and the primary exhaust go into the compressor? (At first I thought that the air entered at the primary level and was then expelled from there, but after looking at the diagram, it seems that both go into the compressor.)
Without a PID diagram, it’s not possible to assist with the analysis; if oil has separated, it generally returns to the compressor’s oil reservoir
It must be an inlet and an outlet; with two-stage compression, there is also a second inlet and a second outlet.
Now I understand; it turns out that primary and secondary intake are defined based on the number of stages of this compressor. Thank you, teacher!
