Screw Compressors

Rated 0 out of 5

Screw compressors are positive displacement equipment. The operating principle of these compressors is based on the decrease in the volume of air in the compression chamber where it is confined, producing an increase in internal pressure until reaching the expected design value, at which time the air is released to the system.

Screw technology is more advanced than its predecessor, the reciprocating or piston compressor. Both systems are positive displacement; The main difference between these technologies is in the way of compressing, which in the case of the screw compressor is continuous along the rotor and in the piston compressor it does so in two phases (suction and compression). This way of compressing the air in the piston generates alterations in the flow, while that of the screw produces a continuous flow of air.
