What are the types of air compressors

Air compressors can be divided into various types according to their working principle, structural characteristics and application needs. Here are some common categories of air compressors:

1. Pistol of piston air compressors:
   • Working principle: Complete the compression process through up and down movement of the piston.
   • Features: Simple structure, stable and reliable, suitable for small and medium-sized enterprises.
   • Parameter range: The pressure range is usually between 0.7MPa and 2.5MPa, and the exhaust volume is between 0.5m³/min and 15m³/min.
2. Screw air compressor:
   • Working principle: Gas compression is achieved through the rotation of the screw.
   • Features: Stable operation, low speed and low noise, and are widely used in large enterprises and multiple industrial fields.
   • Parameter range: The pressure range is between 0.6MPa and 3.5MPa, and the exhaust volume can reach 1m³/min to 100m³/min.
3. Turbo air compressor (centrifugal air compressor):
   • Working principle: Use high-speed rotating turbine blades or centrifugal forces to achieve gas compression.
   • Features: high efficiency, energy saving, stable and reliable, suitable for use in large industrial enterprises.
   • Parameter range: Pressure range from 0.5MPa to 4.0MPa, and the exhaust volume can be up to 10m³/min to 1000m³/min.
4. Frequency converter:
   • Working principle: Intelligently adjust the speed according to air demand to achieve energy saving.
   • Features: The rotation speed can be automatically adjusted according to gas demand, which has significant energy-saving effects.
   • Parameter range: The pressure range is between 0.6MPa and 3.5MPa, and the exhaust volume is between 1m³/min and 80m³/min.
5. Rolling piston air compressor:
   • Working principle: Use a roller crank mechanism to achieve gas compression.
   • Features: Stable operation, reliable and durable, suitable for industrial production and manufacturing.
   • Parameter range: The pressure range is usually between 0.5MPa and 3.0MPa, and the exhaust volume is between 2m³/min and 40m³/min.
6. Scroll air compressor:
   • Working principle: The compression of gas is achieved through the rotation of the scroll disc.
   • Features: Light weight, low noise, small size and high stability, suitable for occasions where noise and volume requirements are required.

In addition, there are some special types of air compressors, such as micro-oil screw machines, oil-free (water lubricating) air compressors, explosion-proof air compressors, etc., which are designed according to specific application needs and environmental conditions.

When choosing an air compressor, factors such as power, exhaust volume, pressure range, maintenance cost and working environment should be comprehensively considered to select the most suitable air compressor model.
