Air compressor classify basically has: Press its construction fundamental, can divide into machine of piston machine pneumatics, machine of screw type pneumatics, compressor of blade type air, centrifugal pneumatics machine, compressor of vortex type air.
By pressure level can divide into: Voltage of low report depress (1.3MPa) of ≤ of the actuating pressure that enrage a road, high pressure (the actuating pressure that enrage a road is 1.3~4.0MPa) , Zuo is pressed (the actuating pressure that enrage a road is reached for 4.0~40MPa over) ;
By compress aeriform form to be able to be divided into cubage type and speed type.
According to unit work whole process attends grease, can divide into machine of two kinds of pneumatics: Oil-lubricated oil and lubricate without grease.
Basis application whole process is must move: Cent becomes movable type and stationary pneumatics occasion, basis driving force gives phyletic cent to become derv engine and electric machinery.
Piston pneumatics machine: In low end is high expend, sale market is replaced slowly.
The crankshaft of engine of electric machinery driver of piston pneumatics machine is rotational, engine crankshaft drives crankshaft to make piston lever moves repeatedly, occurrence cylinder capacity transforms. Because of the change of the pressure inside air cylinder, gas is mixed according to air filter core suck valve to enter cylinder. In reducing whole process, accompany those who follow a cylinder cubage to decrease, compress air to appear. Important run component part more, basically include engine bent axle, gear, crankshaft, piston lever, suck automatic exhaust valve, scroll bearing. Every produce gas is 0.15~100m/min probably, advocate electric machinery power by 2.2kW~550kW.
Machine of piston machine pneumatics is low-cost, machine equipment investment is low. The home can produce a lot of manufacturers of Chinese by oneself make. Before a lot of companies choose engine of piston machine pneumatics, but the locomotive component of machine of piston machine pneumatics a lot of, suck automatic exhaust valve and easy attaint of the look that twist reed, appear it is good to reduce the effect decrease, effect yield gas is very poor, bad news can promote, amount of task of care and maintenance is large. Low end is high in vest in bad news commodity, be being replaced by place of machine of pneumatics of screw type compressor gradually.
Screw pneumatics machine: Produce air feed quantity to be reduced gradually
Screw pneumatics machine divides geminate screw and odd screw. Its fundamental is the extruder screw that rotational and mutual tine adds up to, carry oil and gas engulf from the mouth that take energy of life. Accompanying silk to turn and be carried of lever, tine adds up to cubage to decrease slowly, mixture burning gas pledges the other one aspect of the matter in extruder screw is compressed. After lighting gas to mix segregator of corporeal classics oil gas, eduction can be used compress air.
Machine of pneumatics of screw type compressor, it is good that machine equipment produces gas result, but as a result of time paragraph metabolic attaint promotion, occurrence ministry divulges promotion, produce air feed quantity to be reduced gradually, carry consummate increases originally.

Centrifugal: Air feed amount is large.
Centrifugal still is the important sale market of pneumatics machine, the proportion that holds total sales about is large, chemical plant, the requirement that waits for a domain also is in power project to grow continuously. In driving force industry, the sale of air compressor exceeds other goods. Companion is opposite as everybody applied environment, bad news can promote with what environmental protection sets, empty in the future atmospheric pressure shrinks the city area of machine will gradually outspread.
The discharge range that machine of especially centrifugal pneumatics covers titanium spirit arrives extensively from 20m3/min 4000m3/min, pressure arrives from 0.6bar 80bar, product structure is simple, installation is safeguarded convenient, safeguard, operation cost is low. The product applies extensively at semiconductor of empty cent, electron, spin chemical fibber, food ferments, the numerous domain such as iron and steel.
