Screw Compressors

Abstract

The invention discloses a screw-type air compressor including a machine body. A pedestal is arranged on the bottom of the machine body. A hood is arranged inside the machine body. A male rotor is installed inside the hood and is engaged with a female rotor. One end of the male rotor is connected to the hood through a bearing. A driving gear is installed on the other end of the male rotor and is engaged with a driven gear. By means of a filter core and a second air guiding pipe, air is filtered to remove dust, so that a problem of dents on the surfaces of the male and female rotors when the male and female rotors are directly contacted with dust or tiny sand can be avoided; meanwhile, by means of cooling fins on a side wall of the hood, heat dissipating efficiency of the hood is increased;by embedding a copper core in the cooling fins, heat conduction speed of the cooling fins is increased; by means of a cooling box, air entering the hood can be cooled, so that the air, when entering the hood, can directly cool the male and female rotors, thereby improving cooling effect.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to screw air compressors. Background technique [0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane or rotary screw. Centrifugal compressors are very large applications. Among them, the screw air compressor adopts pre-set configuration. The screw air compressor only needs a single power connection and compressed air connection, and has a built-in cooling system, which greatly simplifies the installation work. Screw air compressors consistently provide high-quality compressed air for all walks of life with its advantages of high efficiency, high efficiency, maintenance-free, and high reliability. Screw air compressors come in pre-packaged configurations requiring a single power connection and compressed air connection, with a built-in cooling syst...

Problems solved by technology

[0003] At present, when the screw air compressor is in use, the female rotor and the male rotor inside the screw air compressor will continuously squeeze the air, which will cause the female rotor and the male rotor to generate high temperature after long-term operation, and if it is not corrected in time The female rotor and the male rotor dissipate heat. After the female rotor and the male rotor accumulate a large amount of heat, they will be deformed or cracked, which will cause damage to the female rotor and the male rotor. However, the existing cooling system cannot cool the female rotor and the male rotor. The cooling effect of the cooling system is greatly reduced. At the same time, the existing screw air compressor lacks a filter device, so that a large amount of dust or tiny gravel in the air enters the screw air compressor, and the female rotor and Due to the dust or tiny gravel in the air, the surface of the male rotor and the male rotor has pits or is corroded by dust
