Screw compressor complete machine

Abstract

The invention relates to the field of air compressor equipment, in particular to a screw compressor complete machine which comprises a moving platform and an air compressor body. A first-stage air compression device, a second-stage air compression device and a third-stage air compression device are fixedly installed in the air compressor body, and a buffer supporting device is movably installed onthe outer side of the moving platform; a supporting rod is movably installed at the lower end in the moving platform, a driving motor is fixedly installed on the left side in the air compressor body,the driving motor is in meshed connection with the left sides of the first-stage air compression device and the second-stage air compression device through gears, and the right side of the second-stage air compression device is in meshed connection with the third-stage air compression device through a gear, so that the three sets of air compression devices can be used for compressing air, the compression ratio and the pressure difference of each stage are reduced under the medium-high pressure exhaust pressure, the axial force and the radial force, generated in the second-stage exhaust process and the third-stage exhaust process, of a rotor are reduced, the overall requirement for the rotor can be lowered, and the service life of the rotor is prolonged.

Description

technical field [0001] The invention relates to the field of air compressor equipment, in particular to a complete screw compressor. Background technique [0002] Air compressor is a kind of equipment used to compress gas. It is often used to provide air pressure output for various pneumatic power equipment, and most air compressors are reciprocating piston, rotating blade or rotating screw. The existing air compressor field , usually based on piston and screw air compressors. [0003] However, most of the existing screw air compressors are two-stage air compressors, so that while the pressure difference between each stage is large, the cooling time during air compression is also short, thereby reducing the overall service life of the air compressor, and The existing air compressor lacks a buffer device for external impact, which makes it easy to fall over when subjected to external impact, causing a potential difference in the internal precise structure, and greatly improv...
