Description

Sealing device for air conditioning refrigeration compressor

Technical Field

The utility model relates to the technical field of refrigeration compressors, in particular to a sealing device for an air-conditioning refrigeration compressor.

Background Art

The refrigeration compressor is the core and heart of the refrigeration system. The ability and characteristics of the refrigeration system determine the ability and characteristics of the refrigeration system. The refrigeration compressor is a driven fluid machine that lifts low-pressure gas into high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it through the piston driven by the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. There are many types of refrigeration compressors. According to different working principles, refrigeration compressors can be divided into fixed-displacement compressors and variable-displacement compressors. In addition, the compressors of industrial chillers are generally divided into centrifugal, piston, screw, scroll, vane and rolling rotor compressors, etc. In addition, according to the sealing conditions, they can be divided into open, semi-closed and fully enclosed types.

The interface pipes of the two parts of the refrigeration compressor are sealed only by sealing rings, and the diameters of the pipe openings of the interfaces of the two parts are not the same. It is difficult to seal the two pipe openings with a simple sealing ring, and the sealing effect is not good. This requires the use of glue or other materials to fix the sealing ring. Since the compressor interface requires regular inspection and maintenance, the method of fixing the sealing ring with glue is not convenient for the inspection of the internal interface. The disassembly of the sealing ring is relatively cumbersome and not very practical. While ensuring the sealing of the interface, its heat dissipation is also a problem.

Therefore, it is necessary to provide a sealing device for an air-conditioning refrigeration compressor to solve the above technical problems.
