Are you referring to the differential pressure in the dry gas seal balance line?
Is it the pressure difference between the seal gas and the flare gas of the reciprocating compressor?
Is it the oil-gas pressure difference and gas-pressure difference of the floating ring seal? The oil and gas pressure difference is the static pressure difference resulting from the height difference of the sealing oil in the sealing oil high-level tank. The pressure difference is the pressure difference between the sealing gas and the balance tube.
Everyone is right; it’s just that the original poster didn’t explain things clearly
I’m referring to the sealing pressure difference of reciprocating compressors. I’m currently calculating the amount of oil that needs to be injected, and there’s an empirical formula for the sealing pressure difference; I’m not sure what that refers to Is it the pressure difference before and after the packing in the reciprocating compressor? Which one do you mean? ? ?
From the compressor’s perspective, it refers to the sealing pressure difference of the piston rings, that is, the degree of harsh operating conditions!
