Type Of Air Compressor

There are many kinds of air compressor (air compressor).

1. According to the working principle can be divided into three categories: volume type, power type (speed type or turbine type), thermal compressor. Air compressor classification

2. According to the lubrication method, it can be divided into oil-free air compressor and oil lubricated air compressor.

3. According to performance, it can be divided into: low noise, variable frequency, explosion-proof and other air compressors.

4. According to its use, it can be divided into: refrigerator compressor, air conditioning compressor, refrigeration compressor, oil field compressor, natural gas filling station, rock drill, pneumatic tools, vehicle braking, doors and Windows opening and closing, textile machinery, tire inflating, plastic machinery compressor, mining compressor, Marine compressor, medical compressor, sand blasting and painting.

5. According to the type can be divided into: fixed, mobile, closed.

Positive Displacement compressors - compressors that increase gas pressure by directly changing the volume of gas.

Piston compressor - is a positive displacement compressor, the compression element is a piston, reciprocating in the cylinder of the piston air compressor.

Rotary compressor - is a positive displacement compressor, compression is achieved by the forced movement of rotating components.

Sliding vane compressor is a rotary varactor compressor, whose axial sliding vane is radial sliding on the eccentric rotor of the same cylinder block. The air trapped between the slides is compressed and discharged.

Liquid-piston compressor - is a rotary positive displacement compressor in which water or other liquid acts as a piston to compress gas and then expel it.

Roots twin-rotor compressor -- a rotary positive displacement compressor in which two Roots rotors engage with each other to trap gas and transfer it from the intake to the exhaust. There is no internal compression.

Screw compressor is a rotary positive displacement compressor, in which two rotors with spiral gear meshing with each other, so that the volume of the two rotors meshing from large to small, so that the gas compression and discharge. The screw compression assembly in the screw air compressor is manufactured internally with the latest CNC grinder and on-line laser technology to ensure precise manufacturing tolerances. Its reliability and performance ensure that the operation cost of the compressor remains extremely low during its lifetime. Adjusting compressors, integral compressors and desiccant series are all new products in L/LS series compressors.

Velocity compressor - is a rotary continuous flow compressor in which the high-speed rotating blade accelerates the gas passing through it, thus converting velocity into pressure. This conversion occurs partly on the rotating blade and partly on the stationary diffuser or refluster baffle.

Centrifugal compressor - A speed compressor in which one or more rotating impellers (blades usually on the side) accelerate the gas. The main flow is radial.

Axial-flow compressor - a velocity compressor in which the gas is accelerated by a bladed rotor. The main flow is axial.

Mixed flow compressor - also a speed compressor. The shape of the rotor combines some characteristics of both centrifugal and axial flow.

Jet compressors - use a high-speed gas or steam jet stream to carry away the inhaled gas and then convert the velocity of the gas mixture into pressure in a diffuser.

Permanent magnet variable frequency compressor -- Because the variable frequency screw air compressor takes advantage of the stepless speed regulation characteristics of the frequency converter, it can start gently through the controller or PID regulator inside the frequency converter; For the occasion of large fluctuations in gas consumption, it can quickly adjust the response.

Unipolar compression screw air compressor - The head is composed of a pair of Yin and Yang rotor screw air compressor. This model is widely used screw air compressor.

Bipolar compression screw air compressor -- the head is composed of two pairs of Yin and Yang rotors. After primary compression, the gas enters secondary compression. The compression ratio is high, the power is higher and the compression air compressor reduces a gear.

Bipolar permanent magnet frequency conversion air compressor -- a new energy-saving product developed since 2014, combined with permanent magnet frequency conversion and bipolar compression technology, has high energy saving efficiency.
