An average rotary screw atmosphere compressor has two interlocking helical rotors Screw Air Compressor china contained in a housing. Air 
will come in through a valve, typically called the inlet valve and is taken in to the space between the rotors. As the screws switch, they reduce the level of the air, therefore 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 component 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 compressor.
A Rotary Screw Atmosphere Compressor is a compressor that uses a rotary-type positive displacement system, called a rotary screw, air-end. … Rotary Screw Compressors also use two inter-twined helical formed screws, referred to as rotors, to compress the air flow.
