Description

Noise reduction type screw air compressor Technical Field The utility model relates to the technical field of air compression, in particular to a noise reduction type screw air compressor. Background Screw air compressors are a type of mechanical device that compresses gas by rotation of screw rotors, and the core component is a pair of intermeshing helical rotors that draw air in, compress and discharge high pressure gas by their rotation. Through investigation, chinese patent utility model discloses a noise reduction type screw air compressor (publication number: CN 221033129U), which comprises a machine body, wherein the bottom of the machine body is fixedly connected with a supporting plate, a sliding hole is formed in the supporting plate, a sliding column is arranged on the inner wall of the sliding hole in a fitting mode, a bottom plate is fixedly connected to the bottom of the sliding column, a strip-shaped box body is fixedly connected to the upper surface of the supporting plate, shock absorption mechanisms are fixedly connected to the front side and the rear side of the inner wall of the strip-shaped box body, a connecting column is fixedly connected to the upper surface of the sliding column, a round hole is formed in the connecting column, and the inner wall of the round hole is fixedly connected with the surface of the shock absorption mechanism.
