A typical rotary screw air compressor has two interlocking helical rotors contained in a housing. Air comes in through a valve, typically known as the inlet valve and can be taken 
in to the space between the rotors. As the screws convert, they reduce the level of the air, hence Screw Air Compressor china increasing the pressure.
The heart of an air compressor is the screw element which can be called air-end. The air-end is definitely the most important component of any screw-type compressor. It’s that area of the machine where the actual compression takes place. It is the cardiovascular of the rotary screw air flow compressor.
A Rotary Screw Air Compressor is a compressor that uses a rotary-type positive displacement mechanism, called a rotary screw, air-end. … Rotary Screw Compressors also use two inter-twined helical shaped screws, known as rotors, to compress the surroundings.
