Abstract

The invention relates to a scroll compressor, in particular to a scroll compressor and an oil-gas separation device thereof. The oil-gas separation device comprises an oil-gas fine separation assembly, a rear cover plate, a secondary separation cover plate, a coarse separation cover plate, a static disc, a movable disc and a machine body; an annular outer ring and a first air guide rib are arranged on the end face of the other side of the static disc; the coarse separation cover plate is arranged on the annular outer ring, and a coarse separation cavity is formed between the annular outer ring and the coarse separation cover plate; a coarse separation gas inlet is formed in the middle of the static disc; the rear cover plate is arranged at the tail of the machine body, a secondary separation cavity is formed between the rear cover plate and the machine body, and a coarse separation exhaust hole communicates with the secondary separation cavity; a second air guide rib is arranged on the end face of the inner side of the rear cover plate, and the secondary separation cover plate is arranged on the second air guide rib; a cavity is formed between the second air guide rib and the secondary separation cover plate, and an air inlet of the cavity communicates with the secondary separation cavity; and air outlet of the cavity penetrates through the inner side and the outer side of the rear cover plate; and the oil-gas fine separation assembly is arranged on the outer side of the rear cover plate. The oil-gas separation effect is improved.

Description

technical field [0001] The invention relates to a scroll compressor, in particular to a scroll compressor and an oil-gas separation device thereof. Background technique [0002] The scroll compressor is mainly composed of a control part, a motor part and a compression part. The compression part has a pair of scroll disks. The main compression process of the scroll compressor is realized by the scroll disks. The refrigerant is compressed into a high-temperature and high-pressure gas by the scroll disks. The high-pressure gas is discharged through the exhaust hole on the fixed scroll, flows to the motor area, and then is discharged through the exhaust pipe. In order to meet the needs of lubrication, sealing and cooling during the use of the compressor, liquid oil is often used. These oils lubricate the moving pairs, thus reducing friction and wear; at the same time, due to the presence of lubricating oil, the amount of leakage through the fit clearance is greatly reduced; fin...
