Refrigeration compressor multi-stage supercharged twin-screw core

Abstract

The multi-stage supercharged twin-screw core of the refrigeration compressor includes a core shell. The core shell has a medium-pressure chamber and a high-pressure chamber inside. The rotor and the driven rotor, one end of the medium pressure chamber is sealed and fixed to the high pressure chamber; the middle part of the high pressure chamber penetrates axially, rotates circumferentially and is sealed and fitted with multiple supercharged rotors, and one end of the high pressure chamber is fixed with a The supercharged motor whose rotor provides rotational power; one end of the supercharged rotor axially extends into the interior of the driving rotor and the driven rotor, and is connected with the circumferential inner wall of the driving rotor and the driven rotor in rotation, and the inner shaft of the supercharged rotor A vent chamber communicating with the medium-pressure chamber and the high-pressure chamber is made. The refrigeration core has the function of multi-stage pressurization and high and low pressure synchronous pressure supply, which can simultaneously output gases of different pressures, and can also reduce the load of a single motor. The core is highly integrated, and is especially suitable for use in equipment with a small internal space.

Description

Technical field [0001] The present invention relates to the technical field of refrigeration equipment, specifically a refrigeration compressor multistage pressurized twin screw movement. Background [0002] Compressor, is the low pressure gas to high pressure gas followed fluid machinery, is the heart of the refrigeration system, it sucks in low temperature and low pressure refrigerant gas from the suction pipe, through the motor operation to drive the piston to compress it, to the exhaust pipe to discharge high temperature and high pressure refrigerant gas, to provide power for the refrigeration cycle, so as to achieve compression → condensation (exothermic) → expansion → evaporation (heat absorption) of the refrigeration cycle, the compressor is divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc., The entry introduces the working principle of the compressor, classification, accessories, specifications, operating requirements, c...

AI Technical Summary

Problems solved by technology

[0008] After analysis, the twin-screw of the compressor in the above-mentioned published patent is different in structure and function compared with the present application, especially there is a big difference in multi-stage supercharging, so it does not affect the novelty of the present application.
