Abstract

A gear compressor comprises a shell and an inner motor installed inside the shell, a gear compressing section drove by the motor to compress the cold media from the evaporator, a gear inflation section to expand the cold media flowing from the condenser. The ratio of the outlet area of the compressing board in the compressing section to the inlet area of the main shaft is 1:1.3 ~ 1:3. The ratio of the inlet area to the outlet area of the sub shaft in the inflation section is 1:1.3 ~ 1:3.

Description

technical field [0001] The present invention relates to compressors, in particular to gear-type compressors. Background technique [0002] Generally, a compressor is a machine that uses the power of a motor or a steam turbine to pressurize working fluids such as air and refrigerant to increase the pressure of the working fluid. This kind of compressor is widely used in the fields of home appliances such as air conditioners and refrigerators, as well as in production fields. [0003] According to the type of compression, the compressor can be divided into positive displacement compressor and turbo compressor. Among them, the volumetric compressor is widely used in the production field, and the volumetric compressor is a working method that increases pressure by reducing volume. Volumetric compressors can be classified into reciprocating compressors and rotary compressors. [0004] The above-mentioned reciprocating compressor uses the reciprocating motion of the piston insi...
