ELECTRIC POWERED AIR COMPRESSOR
131-490 CFM
electric powered portable air compressors are ideal for mining and construction sites where electric power is easily available. These portable compressors offer the benefit of quiet and emission-less operation.
What is the working principle of Rotary screw air compressor?
Here we will go through the basic principle of Rotary screw air compressors.
The Screw air compressor uses a rotary-type positive-displacement mechanism. The screw element consists of two rotors that are similar to a helix each with a different shape and number of grooves/ teeth. Atmospheric air is sucked into this screw element and as the air progresses along the rotors, it gets compressed. The main characteristic is a male and a female rotor element which gets the air to trap and release when as required.
In an oil lubricated rotary screw type air compressor the male rotor is driven by the motor or engine, and the female rotor is driven by the male rotor, or actually by the thin film of oil that’s between them.
In an oil-free rotary screw type air compressor a set of gears controls the timing between the male and female rotor. There is no oil to seal the chamber.
