Rolling rotor type refrigerating compressor structure

Abstract

The present invention relates to the field of compressor technology, in particular, it is a rolling rotor type refrigeration compressor structure. It mainly includes the following several portions: motor, cylinder body base seat, exhaust upper end cover and external shell. The motor, cylinder body base seat and exhaust upper end cover are successively placed in the external shell; on the external shell an air inlet and an air outlet are set. Besides, it also includes the components of ain intake and exhaust isolation silencing plate, air intake and exhaust isolation covering plate and exhaust buffer vibration-reducing pipe, etc. Said invention also provides their connection mode. The invented structure can be extensively used in rolling rotor type refrigeration compressor.

Description

Technical field: [0001] The invention relates to the technical field of compressors, in particular to a rolling rotor refrigeration compressor structure. Background technique: [0002] At present, compared with reciprocating compressors, rolling rotor refrigeration compressors have 30% higher refrigeration efficiency, 30% smaller volume, and 30% lighter weight; but as of 1998, domestic rolling rotor refrigeration compressors The use of household refrigerators has been stopped, and the rolling rotor refrigeration refrigerator compressors have been discontinued; the reason is that the air circuit structure of the rolling rotor refrigeration compressor is directly connected to the low-pressure pipe of the evaporator of the refrigeration system, and the compressed The high-temperature and high-pressure refrigerant is directly discharged into the compressor shell, and then connected to the high-pressure pipe of the condenser of the refrigeration system through the copper pipe on ...

AI Technical Summary

Problems solved by technology

[0005] 2. There are potential failures

[0006] Since the compressed high-temperature and high-pressure gas is directly discharged into the shell, and the heat of the compressor motor makes the internal space of the compressor shell high, the compressor motor winding is in a harsh environment of high temperature all the year round, which is easy to age and poor insulation.

[0007] In addition, since the compressed high-temperature and high-pressure gas is directly discharged into the casing, and the heat of the compressor motor makes the temperature of the inner space of the compressor casing high, the thermal stability of the refrigerated lubricating oil deteriorates, and it is easy to decompose and condense. Corrosion and clogging of refrigeration systems

[0008] 3. High loss

[0013] 4. Poor cooling effect

[0014] Since the motor winding of the compressor is in the innermost part, the current through the copper wire winding does work during operation, and the winding generates heat. The heat must pass through the stator that is also heated by the magnetic circuit to dissipate heat from the motor shell. In addition, the high temperature discharged from the compressor's work The impact of high-pressure refrigerant makes the heat dissipation effect of the shell very poor

[0015] 5. High noise
