Main types of air compressors

Air compressor is a type of machine commonly used in enterprise factories. What are the commonly used types of air compressors in China? Today, the editor will take you to learn more. At present, the types of air compressors on the Chinese market can be mainly divided into screw air compressors, piston air compressors, and centrifugal air compressors. So what are the working principles of these three types of air compressors? What are their characteristics and what fields are they suitable for?

Screw type

At present, enterprises often come into contact with screw air compressors, which have gradually replaced the previous position of piston air compressors, and are popular due to their long service life and high stability. Screw air compressor is a fixed volume, rotary compressor that mainly completes the suction sealing compression exhaust cycle through the meshing and rotary motion of the screw. Its advantages are sturdy, durable, and easy to maintain, but its disadvantages are unstable output pressure and lower energy efficiency than piston air compressors under the same conditions. Screw air compressors are divided into single screw compressors and double screw compressors. Currently, Kaishan screw air compressors have a large market share, and their double screw air compressors and high-quality single screw compressors cannot be underestimated.

Piston type

The piston air compressor has been the "dominant" in the air compressor industry for over a decade. It is a priority choice for enterprises. Its price is cheap and its cost-effectiveness is high. A piston air compressor is a constant volume, reciprocating compressor that mainly completes the suction sealing compression exhaust cycle through the movement and coordination of cylinders, pistons, and valves. Its advantages are a large pressure range, good stability, and stable exhaust pressure. Its disadvantages are large and bulky volume, and relatively high operating and maintenance costs. The Kaishan piston air compressor is currently mainly used in special fields such as high pressure compression.

A centrifugal air compressor is a variable capacity, impeller type compressor that mainly generates centrifugal force through the high-speed operation of the impeller, promoting the high-speed flow of air. Through the conversion effect of the booster, it produces compressed air with a certain pressure and flow rate. The workflow is suction increase expansion discharge. The advantages of Kaishan centrifugal air compressor are large flow rate and oil-free, but the disadvantages are difficult capacity adjustment and easy to cause surging.

Other types

In addition to the several commonly used types of air compressors mentioned by the above editor, other practical air compressors include vortex type air compressors, sliding vane air compressors, axial flow air compressors, etc., which can all be attributed to constant volume, variable volume and other compression methods, which are similar to the analysis process of the aforementioned air compressors. Considering the small demand, the editor will not separately discuss them here.
