HP7- S hydrogen tightening machine bearing wear repair of new technology

With the development of the technology, the liquid ring type tightening machine also presented some modification on the design, some liquid ring type squeeze machine is improved by the plane on the air intake design for cone type, thereby significantly improved extraction can squeeze machine, reduce the operation energy consumption. Compared with the planar type compressed air inlet structure, the cone type tightening machine also has a large change in appearance. Plane tightening machine normal use only the upper intake, upper exhaust structure; While tightening machine of the cone can be used side or the upper intake, the lower exhaust structure. 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. Sauvy industrial 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 and concentricity after repair 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.
