Abstract

This invention relates to a gear-type contractor. The compressing part comprises main bearing, compressed cylinder, outer gear, inner gear and compressing plate; wherein the main bearing is fixed below the driving part, and the ring form compressed cylinder is set below the base bearing and connected together; the outer gear is set inside the cylinder with rotary form, and the inner gear is set inside the outer gear, which will receive dynamic from motor and engage with outer gear to rotary, compressing coolant; the compressing plate is set below the compressed cylinder and connected with it; the auxiliary induction pipe which will send the coolant to inner space of the outer gear, and the output pipe which will send the compressed coolant to chiller can be set in two of the base bearing, the compressed cylinder or the compressing plate. Said invention can increase the coefficient of performance of refrigerating system, and can use carbon dioxide to replace traditional coolant, which is benefit for environmental protection.

Description

technical field [0001] The invention relates to the field of gear type compressors. Background technique [0002] Generally, a compressor is a machine that uses the power of an electric 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, compressors can be divided into positive displacement compressors and turbo compressors. [0004] Among them, the positive displacement compressor is widely used in the production field. The compression working method of the positive displacement compressor is to increase the pressure by reducing the volume. Positive displacement compressors can be divided into reciprocating compressors and rotary compressors. [0005] Reciprocating compressors use the reciprocating mot...
