How Do Rotary Screw Air Compressors Work?

How Do Rotary Screw Air Compressors Work?

In modern industrial machinery, screw compressors are one of the most widespread technologies. Known for their reliability and flexibility, screw compressors are the driving force behind many industrial processes and applications.

There are two basic principles of compression in air compressors. You can also look for the best screw air compressors via https://compressedair.net.au/screw-air-compressors/.

One of them is the principle of repression. There are many types of compressors that use this method, with screw compressors being the most popular.

As the name suggests, screw compressors use a rotary motion to compress air. The compressor has a set of male and female rotors. They will be designed differently so that when they rotate in unison, air will enter between them. 

The male rotor has convex blades and the female rotor has a concave cavity; in this way, they can be connected without contact to achieve compression.

Step by step messing up work

  • The valve opens to draw gas into the compression chamber. The two screw rotors are located in the chamber; When the engine is running, they rotate at high speed.

  • As the impellers rotate, they trap and isolate the air in the cavities between the rotors, thereby moving the air down the chamber.

  • Space shrinks and moves away from the opening valve. Pressure increases when volume decreases.

  • The pressure increases and thus the air condenses.

  • Air pressure activates the compressor exhaust valve, where compressed air can reach a collection container or other storage tank.

  • The air is compressed and can be sent to downstream devices such as dryers and oil/water separators to dry and remove impurities.
