Problems solved by technology

When the compressor is running for a long time or at high speed, the oil will be discharged out of the compressor together with the high-temperature and high-pressure gaseous refrigerant, resulting in insufficient lubrication of the compression parts, which will increase the compressor load and affect the cooling or heating effect. Increased wear and reduced service life

Abstract

The invention discloses a rotary compressor. The rotary compressor comprises a shell, a motor, a compressing mechanism and an oil separation device, wherein the motor is arranged in the shell and separates the interior of the shell into an upper chamber and a lower chamber; the motor comprises stators and rotors; first refrigerant channels are formed in the stators and / or on the peripheries of the stators; second refrigerant channels are formed in the rotors; third refrigerant channels are defined between the rotors and the stators; the upper end of each refrigerant channel is communicated with the upper chamber and the lower end of each refrigerant channel is communicated with the lower chamber; the total areas of the cross sections of the first, second and third refrigerant channels are respectively S1, S2 and S3; S1, S2 and S3 at least satisfy one of the following relational expressions: (S2+S3) / (S1+S2+S3) is not less than 0.45; S2 / S3 is not less than 1; the compressing mechanism is arranged in the lower chamber and below the motor and is provided with a crankshaft and exhaust outlets for exhausting; the oil separation device is arranged at the top of the crankshaft or the rotors. The rotary compressor can reduce oil discharge and ensure higher energy efficiency and long service life.

Description

technical field [0001] The present invention relates to a rotary compressor. Background technique [0002] The compressor will be sealed with special lubricating oil. The lubricating oil is mainly used for the lubrication of cylinders, valve plates, bearings, crankshafts and other components, and plays the role of sealing and assisting cooling. When the compressor is running for a long time or at high speed, the oil will be discharged out of the compressor together with the high-temperature and high-pressure gaseous refrigerant, resulting in insufficient lubrication of the compression parts, which will increase the compressor load and affect the cooling or heating effect. Increase wear and reduce service life. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. [0004] Therefore, an object of the present invention is to provide a rotary compressor, which can r...
