What are the classifications of air compressors?

There are many kinds of air compressors. 1 According to the working principle, it can be divided into three categories: positive displacement compressor, power compressor (rotating speed compressor or turbo compressor) and thermal compressor. 2. According to the lubrication mode, it can be divided into oil-free air compressor and oil-lubricated air compressor. 3. According to the performance, it can be divided into: low noise, frequency conversion, explosion-proof and other air compressors. 4. According to the use, it can be divided into: refrigerator compressor, air conditioner compressor, refrigeration compressor, oil field compressor, natural gas filling station compressor, rock drill, pneumatic tool, vehicle brake compressor, door and window opening and closing compressor, textile machine compressor, tire inflation compressor, molding machine compressor, mine compressor, marine compressor, medical compressor and sand blasting and painting compressor. 5. According to types, it can be divided into: fixed, mobile and closed. (1) positive displacement compressor-a compressor that directly depends on changing the gas volume to improve the gas pressure. (2) Piston compressor-it is a positive displacement compressor, and its compression element is a piston, which reciprocates in a cylinder. (3) Rotary compressor-it is a positive displacement compressor, and the compression is realized by the forced movement of rotating elements. (4) The vane compressor is a rotary variable displacement compressor, and its axial vane slides radially on the rotor eccentric to the cylinder block. The air trapped between the blades is compressed and discharged. (5) Liquid piston compressor-rotary positive displacement compressor, in which water or other liquid is used as piston compressed gas and then discharged. (6) Roots double-rotor compressor is a rotary positive displacement compressor. Two Roots rotors mesh with each other to intercept the gas and send it from the air inlet to the air outlet. No internal compression. (7) Screw compressor-rotary positive displacement compressor. Two rotors with spiral gears mesh with each other, so that the volume at the meshing position of the two rotors changes from large to small, thus compressing and discharging gas. The screw compression component in the screw air compressor is manufactured by the latest CNC grinder, and with the on-line laser technology, the manufacturing tolerance is extremely accurate. Its reliability and performance can ensure that the operating cost of the compressor is always extremely low during its service life. Regulating compressor, integrated compressor and dryer series are all new products in L/LS series compressors. (8) Speed compressor is a kind of rotary continuous air compressor, and the high-speed rotating blades will be accelerated by the gas in it, thus converting speed energy into pressure. This transition occurs partly on rotating blades and partly on fixed diffusers or backflow baffles. (9) A centrifugal compressor is a speed compressor, in which there are one or more rotating impellers (blades are usually on the side) to accelerate gas. The main air flow is radial. (10) Axial compressor is a speed compressor, in which gas is accelerated by a rotor with blades. The main air flow is axial. (1 1) Mixed-flow compressor-It is also a speed compressor. The shape of its rotor combines some characteristics of centrifugal flow and axial flow. (12) Jet compressor-uses high-speed gas or steam jet to take away the inhaled gas, and then converts the speed of mixed gas into pressure in the diffuser. (13) permanent magnet variable frequency compressor-because the variable frequency screw air compressor uses the stepless speed regulation characteristics of the frequency converter, it can be started gently through the controller or the PID regulator inside the frequency converter; For occasions where gas consumption fluctuates greatly, the response can be adjusted quickly. (14) Single-pole compression screw air compressor-The nose is a screw air compressor composed of a pair of male and female rotors. This model is a widely used screw air compressor. (15) bipolar compression screw air compressor-the head consists of two pairs of male and female rotors. After primary compression, the gas enters the secondary compression with high compression ratio, and the power is one step lower than that of the primary compression air compressor. . (16) bipolar permanent magnet variable frequency air compressor-a new energy-saving product developed since 2014, which combines permanent magnet variable frequency and bipolar compression technology, and has high energy-saving efficiency.
