How Do Screw Compressors Work Exactly?
Rotary screw air compressors are widely used across various industries, mainly due to their longevity, reliability and versatility. This article discusses the working principles of screw compressors so that you have a better idea of how they get things done. The oil-injected rotary screw compressor is an example of a positive displacement type compressor. A specific quantity of gas or air is first trapped in a compression chamber, and the space it has occupied is then mechanically reduced. This factor consequently causes an increase in pressure just before the discharge. Any rotary screw compressor will particularly have a pair of inter-meshing rotors in a casing to produce compression. A twin-screw compressor has each rotor comprised of a set of helical lobes attached to a shaft. One rotor is referred to as the male rotor, and the other is called the female rotor. Screw compressor manufacturers in India will decide on the number of lobes and the number of flutes in the male a
