Oil-gas separator of refrigerating system

Abstract

The invention discloses an oil-gas separator of a refrigerating system. The oil-gas separator can supply emergency oil to a compressor so as to control the oil level in the compressor in a reasonable range required by operational parameters of the compressor. The oil-gas separator consists of an upper cover (1), a barrel (2), an air outlet pipe (3), an air inlet pipe (4), a filter screen (5) and an oil return pipe; the upper cover (1) is connected with the barrel (2) to form a cavity; the oil-gas separator also comprises a partition plate (12); the partition plate (12) is connected with the barrel (2) to partition the cavity into a main oil storage cavity (6) and a secondary oil storage cavity (8); the secondary oil storage cavity (8) is communicated with the main oil storage cavity (6) through an opening (13) formed on the partition plate (12); the oil return pipe serving as a main oil return pipe (7) is communicated with the main oil storage cavity (6); the secondary oil storage cavity (8) is provided with a secondary oil return pipe (9); the secondary oil return pipe (9) is communicated with the secondary oil storage cavity (8); and the opening (13) is higher than an oil inlet of the secondary oil return pipe (9).

Description

technical field [0001] The invention relates to the technical field of oil-gas separation equipment for refrigeration systems, in particular to an oil-gas separator for refrigeration systems. Background technique [0002] At present, there is an oil-gas separator for a refrigeration system, which is composed of an upper cover, a cylinder, an air outlet pipe, an air inlet pipe, a filter screen and an oil return pipe. The cavity formed by the connection between the upper cover and the cylinder is used as a place for oil storage, which can be called For the oil storage chamber. In practical applications, when the compressor of the refrigeration system is short of oil in an emergency with the above structure, the oil-air separator cannot supply oil to the compressor in an emergency, resulting in large fluctuations in the oil level in the compressor, which cannot be within the reasonable range required by the compressor’s own operating parameters. If the oil level is within the ...

In practical applications, when the compressor of the refrigeration system is short of oil in an emergency with the above structure, the oil-gas separator cannot supply oil to the compressor in an emergency, resulting in large fluctuations in the oil level in the compressor, which cannot be at a reasonable level required by the compressor's own operating parameters. If the oil level is within the range, it will cause the compressor to burn out if it is serious
