WebbA typical structure of Kobe Steel's oil-free screw compressor is shown in Fig. 2, and the whole system is shown in Fig. 3 .The major parts of an oil-free screw compressor … WebbA screw compressor works according to the positive displacement mechanism. It uses two spiral rotors (male and female rotors) for the compression of air or gas. These rotors mesh in such a way that the concave cavity of the female rotor meshes with the convex blade of the male rotor. The female rotor has a more significant number of blades than ...

Why use Oil-free air compressors instead of lubricated

Webb1 feb. 2000 · Operation. A rotary screw uses two rotors to push air through the compressor, which creates pressure. Compression is accomplished by the main and secondary rotors synchronously meshing in a one-piece, dual-bore housing. The main rotor has helical lobes and the secondary rotor has helical grooves (Fig. 2). WebbIn oil-free compressor technology, a timing gear drives both rotors for harmonic running, with minimum calculated clearance between both elements The basic rotary … fimbles baby rattle
