Graphite rotor for electronic vacuum pump

Product advantages

Raw material selection: Special graphite specially developed as raw material, high strength, high hardness, oxidation resistance, low porosity, abrasion resistance and scouring resistance.

Product processing: Processed in strict accordance with the customer's drawings, the parts fit closely together after installation, with high concentricity, effectively avoiding mechanical stress damage.

Special treatment

Anti-oxidation impregnation: Proprietary technology and nano-antioxidant are used to antioxidate the final product, so that the internal micropores of graphite material are filled with antioxidant and the surface is covered with antioxidant, which effectively improves the high temperature resistance, antioxidation and scouring resistance of graphite rotor and greatly extends its service life.

Anti-oxidation coating: The surface of the graphite rotor (except the threaded part) is coated with a proprietary coating material, which is not infiltrated with the aluminum melt but is firmly bonded with the graphite material and is more resistant to high temperature, oxidation, abrasion and scouring than the graphite material, thus further extending the service life of the graphite rotor after the coating treatment.

Local enhancement: according to the end-user's usage characteristics, the most consumable part of the graphite rotor is locally enhanced to obtain the longest service life at the smallest cost.
