A rotary-screw compressor is a type of , such as an , that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial applications and replace more traditional where larger volumes of compressed gas are needed, e.g. for large refrigeration cycles such as , or for compressed air systems to operate air-driven tools such as and . For smaller rotor sizes th. [pdf]
Rotary-screw compressors use two very closely meshing spiral rotors to compress the gas. In a dry-running rotary-screw compressor, timing gears ensure that the male and female rotors maintain precise alignment without contact which would produce rapid wear. In an oil-flooded rotary-screw compressor, lubricating oil bridges the space between the rotors, both providing a hydraulic seal and transferring mechanical energy between the rotors, allowing one rotor to be e.
