Abstract

The invention discloses a silent noise reduction air compressor. The silent noise reduction air compressor comprises a bottom plate, a box body, an electrical control box, a motor, a screw air compressor, a cooling unit, a first noise reduction unit and a second noise reduction unit; a partition plate is arranged inside the box body and divides the interior of the box body into a first cavity anda second cavity, the screw air compressor is located in the first cavity, and the cooling unit is located in the second cavity. the cooling unit comprises a cooling fan and a cylindrical fan cover, and the cooling fan comprises a driving unit, an impeller, a plurality of fan blades and a cylindrical fan cover body; the fan blades are folding fan blades, three penetrating holes located on the samestraight line are formed in the leading edge vortex flow dividing area of each fan blade, and penetrating holes distributed in a rectangular array mode are formed in the trailing edge vortex flow dividing area of each fan blade; and the second noise reduction unit comprises a sound absorption composite plate and a sound absorption shell. Vortex noise is reduced, so that the vibration frequency ofinternal noise is gradually reduced, and the sound absorption effect is achieved.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a silent and noise-reducing air compressor. Background technique [0002] An air compressor is a device used to compress gas. An air compressor is similar in structure to a water pump. Most air compressors are reciprocating piston, rotary vane or rotary screw. Among them, the screw compressor is a rotary volumetric compressor, in which two rotors with helical gears mesh with each other, so that the volume of the two rotors meshes from large to small, thereby compressing and discharging the gas. In the screw air compressor The advanced screw compression components are manufactured in-house with the latest CNC grinding machines, combined with online laser technology to ensure extremely precise manufacturing tolerances; its reliability and performance can ensure that the operating costs of the compressor are always extremely low during the service life. [0003] In addition...
