An average rotary screw surroundings compressor has two interlocking helical rotors contained in a housing. Air will come in through a valve, typically called the inlet valve and is definitely taken in to the space between your rotors. As the screws change, they reduce the volume of the air, thus increasing the pressure.
The center of an air compressor may be 
the screw element which can be called air-end. The air-end is definitely the most important part of any screw-type compressor. It’s that section of the machine where the actual Screw Air Compressor china compression takes place. It is the center of the rotary screw surroundings compressor.
A Rotary Screw Air Compressor is a compressor that uses a rotary-type positive displacement system, called a rotary screw, air-end. … Rotary Screw Compressors also make use of two inter-twined helical designed screws, known as rotors, to compress the air flow.
