The rotary screw compressor utilizes two rotors, helical screws, to compress the air. There’s a ‘male’ rotor and also a ‘female’ rotor. The blades are of different form, yet fit each various other precisely.

When the rotors start transforming, air will get trapped on one side and get ‘trapped’ between the blades. Considering that the blades are continuously transforming, the air gets pressed to the other end of the blades, and new fresh air gets trapped.

Because this is a continuous procedure, this sort of compressor does not make a lot of noise; it runs peaceful and smooth.

Compared to piston-type reciprocating compressors, the screw compressor is far pricier. It will run 24/7 and 365 days a year with no issues. The capability of screw compressors is generally a lot higher to piston-type compressors.

When you need a lot of air in your workshop or factory, this type of compressor is generally the most effective selection!

Rotary screw air compressors are likewise readily available in two primary applications 

  • Oil-free 
  • Oil injected. 

Here are breakdowns:

  • Oil-Free: Exterior equipment integrates the placement of the counter-rotating screw components, and, since the blades do not get in touch and create friction, no lubrication is required within the compression chamber. As a result, the pressed air is oil-free. Accuracy design within the housing maintains pressure leakage and drops from the stress side to the inlet at a minimum. And since the interior stress proportion is restricted by the difference in air temperature level in between the inlet as well as discharge ports, oil-free screw compressors are frequently constructed with several stages and inter-stage cooling to optimize the stress reach. The transmission driving the mechanism does consist of lubricating substances; oil-free refers to the compression chamber itself, and the delivered air is without foreign pollutants beyond those located inherently in the air that travels through the intake.
  • Oil Injected: In oil-injected rotary screw air compressors, a fluid is injected right into the compression chamber to cool down and oil the compressor aspects relocating components to cool down the air being pressed in the chamber, as well as to help lessen leakages from returns into the chamber during discharge. While oil is the most typical fluid used today because of its properties of lubricating and securing, water as well as various other polymers are sometimes used. The oil is after that separated as well as goes through a filter as well as cooler prior to it cycles back right into the process once more. The compressed air might be still hot and oftentimes is run through a cooler, relying on end usage.
