Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration units, in particular to an oil separation device for refrigeration units. Background Art

[0002] The oil separator allows the high-pressure gas from the compressor to flow along the spiral outer wall of the guide vanes inside the oil separator. The lubricating oil is separated from the working gas through centrifugal force and gravity, and flows down along the inner wall of the cylinder. The gas passes through the porous baffle and is led out of the oil separator through the central pipe. The separated lubricating oil is concentrated in the lower part of the oil separator and can be discharged regularly or automatically returned to the crankcase of the compressor using a float valve.

[0003] Most of the failures that occur when the air conditioner is in use are caused by the compressor. This means that when repairing the compressor, the air conditioner outdoor unit installed with the refrigeration unit must be disassembled. At the same time, the oil separator used to separate the lubricating oil also needs to be disassembled and inspected in order to confirm the oil quality of the refrigeration unit components. However, since the oil separator is installed in a relatively small position of the outdoor unit and the oil separator is connected to the outside world through fixing bolts, it is necessary to repeatedly rotate and disassemble multiple fixing bolts in a small position of the outdoor unit. This method greatly reduces the efficiency of oil separator maintenance and inspection. For this reason, we propose an oil separation device for refrigeration units. Utility Model Content
