Abstract

The invention discloses a multi-screw compressor which is large in displacement and small in occupied area. The compressor comprises a shell, a motor, couplers and 1-2 sets of female-male rotors, wherein each set of female-male rotors comprises 2-4 pairs of female-male rotors; each pair of female-male rotors comprises a male rotor and a female rotor; the male and female rotors in each pair are engaged with each other; the male rotors in each set of female-male rotors are connected in serial through the coupler; air inlet and outlet channels are formed in each set of female-male rotors; an air inlet and an air outlet are formed in the shell; the air inlet channels are communicated with the air inlet; the air outlet channels are comprises with the air outlet; the output end of the motor is connected with one of the male rotors in each set of female-male rotors and drives the male rotor to rotate. The multi-screw compressor has the beneficial effect that the displacement of the compressor of the same size is increased and the operation efficiency of the compressor is improved.

Description

technical field [0001] The invention relates to the field of air-conditioning and refrigeration equipment, in particular to a multi-screw compressor. Background technique [0002] The screw compressor is a rotary compressor that uses the screw-shaped rotor to perform rotary motion in the cylinder to compress and deliver gas. Screw compressors are widely used in mining, chemical industry, power, metallurgy, construction, machinery and refrigeration and other departments. The displacement is 25~38000m 3 / h. When inhaling under atmospheric pressure, the single-stage exhaust pressure can reach 0.5 MPa; the two-stage and three-stage exhaust pressure can reach 1.2 MPa and above 3 MPa respectively. Single screw compressors are all liquid injection cooled. In industrial production, twin-shaft (twin-screw) compressors are the most common, but single-shaft (single-screw) compressors are also gradually being used. The compression of air in the screw air compressor is achieved by t...
