A typical rotary screw surroundings compressor has two interlocking helical rotors within a housing. Air will come in through a valve, typically called the inlet valve and is taken into the space between your rotors. As the screws convert, they reduce the volume of the air, thus increasing the pressure.
The heart of an air compressor may be the screw element which can be called air-end. The air-end is Screw Air Compressor china usually the most important component of any screw-type compressor. It’s that part of the machine where in fact the actual compression occurs. It is the center of the rotary screw atmosphere compressor.
A Rotary Screw Atmosphere Compressor is a compressor that runs on the rotary-type positive displacement system, called a rotary screw, air-end. … Rotary Screw Compressors 
also use two inter-twined helical shaped screws, known as rotors, to compress the surroundings.
