Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] like figure 1 Or 2 shows the structure schematic diagram of the oil-gas separator of the prior art refrigeration system, it is made up of loam cake 1, cylinder body 2, outlet pipe 3, air inlet pipe 4, filter screen 5 and oil return pipe, and filter screen 5 is horizontally installed on In the cylinder 2, the cavity formed by the connection of the upper cover 1 and the cylinder 2 is divided into upper and lower cavities, the cylinder 2 is installed on the base 14, and the filter screen 5 is punched with three through holes, two of which are air supply pipes 3 through the use, the purpose is to make the curved section of the air outlet pipe 3 be located in the lower cavity, and the air inlet of the air outlet pipe 3 is located in the upper cavity, and the remaining through holes are used for the air inlet pipe 4 to pass through, so that the outlet of the air inlet pipe...

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 ...
