How does an Air Compressor work?

An air compressor includes an electric motor that compresses the air into a tank. The compressed air can be released at the picked pressure when required. How does an air compressor work? What are the criteria for picking an appropriate gas compressor? Well there are a range of different compressor types.

Let’s continue with a summary. Normally compressors utilized in automation and workshops are the so-called plus displacement compressors. Here pressure is created when gas is drawn into a container and the volume of that space is reduced. For this short article we wish to restrict ourselves to this type of compressor. Let’s take a closer dive into the reciprocating compressor.

The crankshaft turns which moves the piston inside the round housing. An inlet valve also called an intake valve enables fresh air to enter the cylinder. This is done throughout a suction blow from the cylinder. The vacuum valve deflates or opens at high pressure throughout the pressure paddle.

When it is compressed, the air is heated. This is an issue for each compressor. The result is not just a less efficient compression cycle, but also the danger of a genuine surge if any combustible compounds, such as oil or lubricants, touch with the piston and air. The pressure of a single phase compressor is restricted to an output pressure of about 10 bar or 145 pounds To achieve greater pressures, you can utilize a multi-step compressor.

In a 2 phase compressor, the big piston builds the first stage. The air that exits the first stage can now be cooled before entering the 2nd phase. With a two-stage compressor, you can achieve pressure in excess of 20 bar or 290 psi. Multistage compressors can also be utilized with high-power water-cooled jackets to avoid getting too hot. Based upon its working concept, the reciprocating compressor offers just pulse compressed air.

So this type of compressor is utilized in conjunction with a tank. However, making use of a tank offers the benefit that the compressor can be operated with a two-point controller, resulting in less power usage and wear.

The diaphragm compressor comes from the piston compressor family. Here the suction chamber of the piston is shut by a diaphragm. The benefit of a diaphragm compressor is the compressed air in the compression chamber does not come into contact with the piston and is lubed. Therefore it can be kept devoid of oil. These are a few examples:


The main issue of a diaphragm compressor is usually its diaphragm itself due to the fact that versatility is restricted. Diaphragm compressors are utilized for instance in the food industry or for filling divers bottles.

The working concept is totally unique from the so-called rotary compressor, which is also called a vane compressor. A typical rotary compressor has a round housing. Adjustable rotors with their center point on the drive shaft are linked to the housing.

When the pivot rotates, these rotors develop a chamber of different sizes. Air is compressed into the largest chamber, then left and compressed in the tiniest chamber. An advantage here remains in pulsed free circulation in contrast to piston compressors. So an air tank may be optional. In addition, these compressors are low noise and relatively insensitive to dirt.
