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.

The failure characteristics of large pump units are that the influence is great, the reasons are complicated, it is difficult to observe and the failure rate is hard to determine. The main failures of large pump units are as follows: burn out of thrust bearing liner of the motor, failure of stator and rotor coil insulation of the motor, wear-and-tear of guiding bearing and shaft neck of the pump, breakdown of adjusting mechanism of the pump blade, and pump cavitation. The reasons of main failures are studied in design, structures, installation and operation etc.
