Abstract

The invention provides an oil-gas separation system for an oil injection screw vacuum pump. The problem of high equipment maintaining cost of a first-level fine separator used in an existing oil injection screw vacuum pump can be solved. The oil-gas separation system for the oil injection screw vacuum pump comprises a main machine of the oil injection screw vacuum pump and a fine separator and is characterized in that a rough separator is arranged between the main machine of the oil injection screw vacuum pump and the fine separator, and the oil injection screw vacuum pump, the rough separator and the fine separator are sequentially connected through exhausting coupling pipes.

Description

technical field [0001] The invention relates to the technical field of oil-gas separation, in particular to the technical field of oil-gas separation of oil-injected screw vacuum pumps, in particular to an oil-gas separation system for oil-injected screw vacuum pumps. Background technique [0002] Most of the existing oil-injected screw vacuum pumps use a first-stage oil-gas separator, that is, an oil-gas fine separator is directly installed at the rear end of the oil-injected screw vacuum pump host to realize oil-gas separation. The filter element and the seal are assembled. The oil-gas mixture discharged from the main engine enters the cylinder tangentially along the cylinder of the oil-gas fine separator. The oil-gas mixture hits the inner wall of the cylinder in the cylinder, and is initially separated by cyclone and sedimentation, and then the mixed oil and gas are re- After being adsorbed and separated by the oil-gas separation filter element, it is discharged from the...
