What is the difference between screw type and impeller type of air compressor?
Vane type air compressor is centrifugal air compressor, its principle is: gas driven impeller rotating speed, the centrifugal force generated due to gas, gas in the impeller in the flow, so that the gas flow rate and pressure through the impeller is improved, continuous production of compressed air. The centrifugal air compressor is a speed compressor. When the air load is stable, the centrifugal air compressor works stably and reliably.
There are two kinds of Screw Compressors: twin screw and single screw. The invention of single screw air compressor is more than ten years later than double screw air compressor, and the design of double screw air compressor is more reasonable and advanced. The double screw air compressor overcomes the disadvantages of unbalanced single screw air compressor and weak bearing, and has the advantages of long service life, low noise and energy saving. After the maturity of technology in 80s, its scope of application is expanding day by day.Single screw air compressor and worm air compressor, single screw compressor meshing pair is composed of a star wheel 6 head screw and 2 tooth form 11. At the same time with the two wheel worm worm gear even force balance and displacement of double air compressor has the advantages of small size, only 9 cubic meters per minute (9m3/min) worm compressor piston weight is only 1/6.Dynamic compressor: also called speed type or vane type compressor;Rationale: the kinetic energy of the rotating blade is used to provide energy to the gas, and then the kinetic energy of the partial gas is converted to the pressure energy.
The working principle of screw type air compressor is composed of a pair of parallel rotor gear together (or screw rotation) in the cylinder, the volume change of the rotor slot between the air continuously produce periodic, screw compressor working cycle can be divided into the process of breathing (inhaling and closed process), compression and exhaust process.
