An average rotary screw air compressor has two interlocking helical rotors within a housing. Air comes in through a valve, typically known as the inlet valve and is usually taken in to the space between the rotors. As the screws change, they Screw Air Compressor china reduce the volume of the air, hence increasing the pressure.
The heart of an air compressor is the screw element which can be called air-end. The air-end is the most important part of any screw-type compressor. It’s that part of the machine where the actual compression occurs. It is the cardiovascular of the rotary screw air flow compressor.
A Rotary Screw Air flow Compressor is a compressor that runs on the rotary-type positive displacement mechanism, called a rotary screw, air-end. … Rotary Screw Compressors also make use of two inter-twined helical 
shaped screws, referred to as rotors, to compress the air.
