SO, HOW CAN ROTARY SCREW COMPRESSORS COMBINE ALL OF THESE BENEFITS IN A SINGLE PACKAGE? THE SECRET TO THEIR SUCCESS LIES IN THEIR INGENIOUS TECHNOLOGY.
Let’s take a look at the working principle of a rotary screw compressor.
As the name indicates, at the heart of these machines are two screws, which are also referred to as male and female rotors. They are driven either by the male rotor or by a timing gear:
In oil-injected screw compressor technology, the male rotor drives the female rotor. In oil-free compressor technology, timing gears drive both rotors for harmonic running, with minimum calculated clearance between both elements.
In either case, the male and female rotors spin in opposite directions. As a result, air is drawn in-between them. As the cycle progresses, the decreased space between the rotors and their housing leads to air compression. That compressed air is displaced to the outlet.
