The most common type of air compressor

Air compressors, or air compressors, are indispensable equipment in the industrial field. They are mainly used to compress and store air and provide power for various pneumatic tools, equipment and systems. In the air compressor market, there are many types of air compressors, the most common types of which mainly include the following:

1. piston air compressor:
   • working principle: Compress gas through the reciprocating movement of the piston in the cylinder.
   • Features: simple structure, relatively low price, suitable for small-scale, low-pressure occasions.
   • Disadvantages: Due to the friction and wear caused by the movement of the piston, regular maintenance is required.
2. Screw air compressor:
   • working principle: Use two intermeshing screw (female screw and male screw) to rotate in the casing, so that the gas is compressed between the screw and the casing.
   • Features: smooth operation, low noise, small vibration, and can run continuously without failure for a long time.
   • Advantages: Suitable for occasions that require continuous and stable gas supply, such as large factories, mines, etc.
3. Centrifugal air compressor:
   • working principle: The gas is compressed by a high-speed rotating impeller, and the gas is thrown to the outer edge of the impeller under the action of centrifugal force to achieve compression.
   • Features: large flow, high efficiency, suitable for large-scale, high-flow occasions.
   • Application: Commonly used in large-scale chemical industry, metallurgy and other industrial fields.
4. Scroll air compressor:
   • working principle: Use the relative rotation of the scroll (moving scroll and fixed scroll) to compress the gas.
   • Features: small size, light weight, low noise, suitable for occasions with strict requirements on noise and vibration.
   • Advantages: simple structure, convenient maintenance, and high efficiency and energy saving.
5. Sliding vane air compressor:
   • working principle: The volume of the cylinder is changed by the sliding of the sliding vane in the cylinder, so as to realize the compression of the gas.
   • Features: simple structure, small size, light weight, suitable for small and portable occasions.
   • Application: Commonly used in pneumatic tools, small machinery and other equipment.

In summary, piston, screw, centrifugal, scroll and sliding vane air compressors are the most common types of air compressors in the market. Each type has its own unique working principle, characteristics and application occasions, and users should consider it comprehensively according to actual needs when choosing.
