What is a screw air compressor?
A screw air compressor is a type of positive displacement compressor that uses two intermeshing helical rotors, known as screws, to compress air. As the rotors rotate, the air is drawn in and trapped between them, then compressed as it moves along the length of the rotors. The compressed air is then discharged at the outlet of the compressor.
For businesses that need a constant air supply or that require consistent, reliable compressed air, there isn’t a better option than a Rotary Screw Air Compressor.
Rotary screw compressors work by using a pair of intermeshing helical rotors to compress air. Here's a brief overview of how they work:
Air intake: The process begins with atmospheric air intake through an inlet filter. The air enters the compressor’s housing and moves towards the area between the rotors.
Compression: Inside the compressor, the rotors, which are typically helical in shape, rotate in opposite directions. As the rotors turn, the air is trapped and gradually compressed as it travels along the length of the rotors. The compression occurs as the air is squeezed into smaller and smaller spaces between the rotors.
Discharge: Once the air is compressed, it is pushed toward the compressor’s outlet and discharged as high-pressure compressed air.
Cooling: During the compression process, the air heats up. Therefore, rotary screw compressors are equipped with cooling systems, such as air or water cooling, to dissipate the heat and reduce the temperature of the compressed air.
Lubrication: Some rotary screw compressors utilize oil for lubrication and sealing between the rotors. The oil also helps in dissipating the heat and sealing any gaps between the rotors and the compressor housing, ensuring efficient compression.
