What are the types of air compressor

Air compressors (air compressors) are widely used equipment in industrial production. They can be divided into many types according to different working principles and structural characteristics. The following are the main types of air compressors:

volumetric air compressor:

piston air compressor: It is made by the principle that the piston reciprocates in the cylinder to compress and discharge the gas. This kind of air compressor has simple structure, stable work, but the noise is large.

Screw air compressor: screw air compressor is mainly composed of a pair of parallel configuration of the male and female rotor (screw), they mesh through the gear. The rotor compresses and transmits air by rotation, thereby generating pressure. This type of air compressor is very common in the current industrial production, especially in the field of large, continuous gas supply, such as electronics, machinery and food processing. Among them, the screw air compressor is divided into single screw air compressor and twin screw air compressor.

speed type air compressor:

centrifugal air compressor: The working principle is to use centrifugal force to accelerate the air, and then reduce the airflow speed through the diffusion device to increase its pressure. This kind of air compressor is compact in structure, high in efficiency, and the gas is not polluted. It is especially suitable for occasions where the gas volume is large and high pressure is required. The centrifugal air compressor has relatively high requirements for manufacturing materials and technical level.

Axial flow air compressor: It is a kind of large flow air compressor, which drives the air flow through one or more rotating shafts. The airflow usually flows parallel to the axis of rotation of the shaft and increases its pressure energy after passing through the moving blades. This type of air compressor has large gas flow and light weight, and is mainly used in power stations, ironmaking blast furnaces, pharmaceuticals and other fields.

Other types of air compressor:

oil-free water spray air compressor: The working principle of this type of air compressor is to compress air through the rotary motion of the screw compressor, and use the water spray system to cool the high temperature air and form a seal. The water spray system not only helps to reduce the air temperature, but also forms a water film during the compression process, which plays the role of lubrication and sealing, thereby improving compression efficiency and reducing leakage. Oil-free water jet air compressor is suitable for high air quality requirements, such as food, pharmaceutical and chemical industries.

When choosing the right air compressor, you need to take into account the working environment, gas demand, energy consumption and budget and other factors. Different types of air compressors have their own unique advantages and disadvantages and scope of application, so understanding their differences will help to make a more reasonable choice.
