Title: Oil-free screw compressor
Inventor: AOKI MASAKAZU
IPC: F04C18/08
Filed: 1994-09-28
Abstract: PURPOSE: To prevent seizure and scuffing phenomena, even if the surface of a rotor contacts with each other in gas of high temperature, by providing films having different performances from the suction side to the discharge side of the rotor of an oil-free screw compressor. CONSTITUTION: A film unnecessary of high lubrication performance and abrasion resistance is adopted for a suction side where atmospheric temperature is comparatively low compared with a surface film of a rotor so as to have less thermal expansion rate between rotors and less scuffing. On the other hand, a film in the discharge side of the rotor which directly contacts with high discharge air, has highest possibility of contacting with each other and considerably deteriorate its performances in the case of abrasion and damage so that the film of this part is made to have high adhesion property to a material metal, lubrication performance, and abrasion resistance. Sometimes adhesion property, lubrication performance, and abrasion resistance does not reach sufficient values in the suction side where atmospheric temperature does not rise, so that the rotor treated by a film on its surface is heated to a temperature equivalent to the intermediate degree before incorporated in a compressor.
