High-engaging and low-noise screw compressor system and screw compressor

Abstract

The invention relates to a high-engaging and low-noise screw compressor system. The system comprises a sliding valve, a female rotor, and a male rotor. Upper and lower positions of the female rotor and the male rotor are engaged, the sliding valve is located on one sides of the female rotor and the male rotor, the high-engaging and low-noise screw compressor system does not replace any parts, andonly the female rotor and the male rotor are engaged in the up and down direction. The sliding valve is mounted and located on one sides of the female rotor and the male rotor, the engaging effect between the female rotor and the male rotor can be effectively improved, the whole property of a screw compressor is improved, the problem that due to the fact that the sliding valve is not stable, the compressor is frequently loaded and unloaded can be solved, the noise of the screw compressor is lowered, and the invention further provides the compressor with the high-engaging and low-noise screw compressor system.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a high meshing and low noise screw compressor system and a screw compressor. Background technique [0002] With the development of air-conditioning technology, twin-screw compressors have been widely used in the field of commercial air-conditioning due to their advantages of high reliability, strong dynamic balance, small footprint, high volumetric efficiency, and simple structure. The current twin-screw compressors all adopt the left and right structure of the male and female rotor meshing form, but the screw compressors with this structure have problems such as poor meshing effect of the male and female rotors, poor automatic loading stability and high noise. [0003] At present, the main reasons for the poor meshing effect of the male and female rotors, poor automatic loading stability and high noise in twin-screw compressors are: (1) The left and right structures are used...

AI Technical Summary

Problems solved by technology

The current twin-screw compressors all adopt the left and right structure of the male and female rotor meshing form, but the screw compressors with this structure have problems such as poor meshing effect of the male and female rotors, poor automatic loading stability and high noise.

[0003] At present, the main reasons for the poor meshing effect of the male and female rotors, poor automatic loading stability and high noise in twin-screw compressors are: (1) The left and right structures are used to mesh the male and female rotors. During the meshing process, the compressed refrigerant gas exists For the reaction force of the male and female rotors, the male and female rotors need to overcome the reaction force for meshing, so the meshing gap between the male and female rotors will become larger, the meshing effect will be worse, and the compression effect of the compressed gaseous refrigerant will be worse, thus affecting the performance of the compressor; (2 ) The gas after the meshing of the male and female rotors flows to the exhaust pipe through the bent pipe, the vortex of the air flow will reverse the slide valve, and when the air flow pressure is too high, the slide valve will move, so that the compressor cannot run stably at the setting Under constant load; (3) The gas after the meshing of the male and female rotors flows through the bent pipe to the exhaust pipe, and the air flow bends and flows, resulting in loud noise
