The Circulation-hydrogenation Compressor Model BLC-305/A is an important equipment with Hydrogenation devices, which is imported by Lanzhou Petrochemical Company Refinery. Due to high-speed rolling periodically, the spare parts of this compressor, to a varying extent, show a lot of signs of wear and tear. Especially, the axle sleeve of the rotor axle of the compressor is so worn to the greatest degree that its work efficiency decreases by a big margin. Machinery Factory of Lanzhou Petroleum Processing and Chemical Complex has undertaken this task to repair the rotor.
