Hydrogen tightening machine bearing wear repair

Hydrogen tightening of commonly used equipment for hydrogen tightening machine, hereinafter referred to as hydrogen compressor. The tightening machine is altered hydrogen gas volume to complete gas tight and walk process. Hydrogen compressor in the process of operation, the demand on both ends of the spindle adopts mechanical seal to avoid fluid leakage in the equipment, due to the bearing use life problems or mechanical seal static ring with elements such as, easy to form a bearing stuck in the process of operation, or loose, and rotor shaft between relative motion to form a rotor shaft wear problem. Equipment damage reason analysis: ( 1) Normal metal fatigue wear: due to the equipment in a state of high temperature and high load work for a long time, the fatigue properties of metal itself in a certain period will be shown, the bearing clearance with the axis of appearance, at this time if not found in time fit clearance will incur in the process of operation. Bearing and shaft relative motion appearance, can be formed within a short period of time axis of the serious wear and tear; （ 2) To maintain the wrist lack care: bearing under working state if smooth and cooling is not in place, easy to cause the bearing itself operation increase friction, temperature, and presents the ablation phenomenon, transmitting torque will effect to the fitting surface of bearing and shaft appearance brings wear, thus incurred fit clearance, incur shaft wear and tear. After understanding the reason, you should choose the appropriate repair technology, common use on-line maintenance technology, more like a sauvy carbon nano polymer materials. Hydrogen tightening machine bearings wearing sauvy on-site repair process of the status of the industry on the basis of enterprise equipment with the first detailed analysis and specific repair plan, first of all to ensure repair precision, including surface roughness after repair and concentricity request, at the same time, according to the equipment operation environment targeted choose carbon nano polymer material, meet the demand of the long-term work under the environment of working conditions on site. On-site repair steps are as follows: does size according to the practice of field measurement of the corresponding repair tooling manufacturing processes; Does stop appearance in addition to the disposal of oil; Does appearance coarsening disposal; Does to reconcile and daub carbon nano polymer materials, and with the repair tools to restore worn bearing size; Does cure: heating curing 2 hours, to guarantee the data complete curing; Does remove repair tooling after removal of extruding the redundant data and micrometer size detection accuracy; Does check repair surface, then daub secondary carbon nano polymer materials and hot charging bearing complete repair. Sauvy carbon nano polymer field repair hydrogen tightening machine spindle bearing wear:
