What are the types of air compressor

Air compressors can be divided into the following main types according to their working principles and uses:

1. Piston air compressor: Piston air compressor is a device that compresses air by reciprocating the piston in the cylinder. It usually includes two types of single-stage and multi-stage, and has the advantages of simple structure, convenient operation and long service life. However, since the inertial force of the reciprocating motion of the piston is large, large vibration and noise are generated.

2. Screw air compressor: Screw air compressor is a device that compresses air through the mutual meshing of yin and yang rotors. It has the advantages of compact structure, small footprint, high efficiency and high reliability, so it has been widely used in industrial production. In addition, the screw air compressor also has a lower maintenance cost and a longer service life.

3. Centrifugal air compressor: Centrifugal air compressor is a device that compresses air by centrifugal force. It is usually composed of multi-stage impellers, and the air is gradually accelerated between the impellers and gains pressure. Centrifugal air compressor has the advantages of large flow, high pressure and high efficiency, and is suitable for large-scale industrial production and occasions requiring high-pressure air.

4. Scroll air compressor: Scroll air compressor is a device that forms multiple compression chambers through the meshing of fixed scroll and movable scroll, and compresses air through spiral blades. It has the advantages of simple structure, small footprint, low noise and long service life, so it has been applied in some specific occasions.

5. Axial flow air compressor: Axial flow air compressor is a device that compresses air through a high-speed rotating axial flow impeller. It has the advantages of large flow, high efficiency, compact structure, etc., and is suitable for occasions that require a large amount of air.

Duplex air compressor: Duplex air compressor is a combination of two or more different types of air compressors. It can be combined according to different needs to meet specific production needs.

In addition to the above several main types, there are some special purpose air compressor, such as refrigeration compressor, ventilation compressor, etc. These air compressors have a wide range of applications in specific areas.

When choosing a suitable air compressor, many factors need to be considered, such as compressed air demand, production efficiency, maintenance costs, etc. At the same time, it is also necessary to consider the energy efficiency level and environmental performance of the air compressor to ensure the sustainability and environmental protection of the production process.

The "water lubricated air compressor" of Shanghai granklin group is inherently oil-free in compressed gas. granklin group also has complete air compressor qualification and can be used in many industries.
