Air compressor is a favourable turn coming back of electromotor or diesel engine instrument can be changed for atmospheric pressure can, offer dynamic to produce demand equipment a kind of mechanical equipment, common air compressor classifies a few kinds as follows:
One, air compressor classification:
1, differ by structure and working principle can divide for the following 5 kinds:
; of machine of * piston pneumatics
; of machine of pneumatics of * screw type
; of machine of pneumatics of * blade type
; of machine of pneumatics of * centrifugal type
; of machine of pneumatics of * vortex type
2, can divide by actuating pressure grade kind:
Machine of * low-pressure pneumatics (discharge baric force ≦ 1.3MPa);
Machine of pneumatics of * middling pressure (discharge baric force 1.3 ～ 4.0MPa);
Machine of pneumatics of * high pressure (discharge baric force 4 ～ 40MPa);
3, whether to in reducing a process by gas, mix with lube can divide for:
* has oil or; of machine of small oily pneumatics
* does not have oily pneumatics machine.
4, whether to move to be able to divide again by the machine for:
; of machine of * stationary pneumatics
Machine of pneumatics of * movable type (can divide again move for dynamoelectric shift and derv) ;

Air compressor classification and define
2, actor defect and applied domain introduce air compressor.
1, piston pneumatics machine (summary: Low end high cost, be washed out gradually by the market)
* advantage: Price of piston pneumatics machine is dog-cheap, installation cost is low, there is many manufacturer to be able to produce; by oneself in home
* defect:
Component of => machinery movement is very much, reach relevant component and safety wear away easily and attaint;
=> reduces aeriform efficiency low, measure with power consumption big, maintain workload big;
=> cannot produce; of machine of large capacity pneumatics
=> noise is big, it is person place cannot the; inside limits of normal susceptive decibel
This shows, piston pneumatics machine belongs to product of low end empty press, had been replaced by screw pneumatics machine at present.
2, screw pneumatics machine (summary: Efficiency yield gas is tall, noise is low)
Machine of screw type pneumatics distributes machine of pneumatics of the screw that it is sheet and machine of double screw pneumatics again.
* advantage: Equipment produces morale efficiency tall, n uses up low;
* defect: Produce tolerance to be able to decrease according to the addition of use fixed number of year.
3. blade type (summary: Production cost is low)
* advantage: The structure is simple, component is little, production cost is low, be defeated by tolerance big;
* defect: In-house and mechanical orgnaization wears away big, service life is brief.
Machine of pneumatics of 4. centrifugal type (summary: Tolerance is big, volume is large)
* advantage: Produce tolerance tremendous,
* defect: Volume is huge, need is very big hold use ground.
