Screw Compressor Sales & Services

Screw compressors are a marvel of engineering, utilizing a unique mechanism to generate compressed air efficiently. The working principle of screw compressors involves two interlocking helical rotors that compress air as they rotate. As the rotors mesh together, they create pockets of trapped air, which are progressively compressed along the length of the rotors. This continuous compression process results in a steady supply of compressed air at the outlet.

 

In an oil-injected rotary screw compressor, a thin film of lubricating oil ensures frictionless rotation while also serving as a cooling medium, carrying away heat energy during compression. This oil undergoes cooling in a heat exchanger before re-entering the aired. Conversely, in an oil-free rotary screw type air compressor, special rotor coatings act as a lubricant and aid in heat dissipation, ensuring a 100% oil-free air output.

The fundamental principle of a rotary-type screw air compressor lies in the opposite rotation of male and female rotors. Powered by a prime mover, the airend’s rotor rotation creates a vacuum, drawing surrounding air through the air filter and into the aired. As the rotors revolve, air becomes trapped within the interlocking lobes, progressively compressing as the rotors advance.

Air intake begins with atmospheric suction, passing through a filtration system that sieves out suspended particles. This filtered air then journeys into the core of the rotary screw air compressor the aired. Within this critical component, air becomes ensnared between the meshing lobes of the two rotors. As these rotors whirl, they sequentially squeeze the captive air pockets, ultimately releasing compressed air at the outlet of the aired.
