INA bearing operation work inspection maintenance methods of fever

Imported bearings after installation, in order to check whether installed correctly, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. Dynamic operation, from the beginning of the no-load speed, slowly up to the rated operating conditions. Test run to check the items, whether there is abnormal sound, INA bearing temperature, lubricant leakage or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection. Bearing temperature, average according to the external temperature of the bearing. But using the oil hole directly measuring the temperature of the bearing outer ring more accurate. INA bearing temperature, from the beginning of the work gradually rise, usually 1 ~ 2 hours after the temperature stability. If the bearing installation, the temperature will rise sharply, abnormal high temperature. The reason such as lubricant, bearing clearance is too small, too much bad installation, excessive friction sealing device, etc. 1. Keep the bearing lubrication clean inspection on imported bearings should be clean before INA bearing surface, and then carefully check bearing oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace, and bad seal will cause damage to the bearing cloud caused by abnormal equipment downtime. 2. Pay attention to cover exposed bearing inspection bearing don't let the noise of the bearing's exposure to pollutants or moisture environment. If the job is interrupted, should with oil film, paper or similar material by machine. If don't have to remove and may perform inspection of cleaning without masking of bearing, to clean with brush with petroleum solvent coating, then dry with a lint-free cloth or with compressed air to blow dry, Be careful not to let the bearing component starting rotation) 。 With a little mirror, and the probe used in the similar to the dentist to check INA bearings of the orbit plane, retainer and beads. Do not clean the encrypted block or dust bearing; You just wipe the outer surface. If the bearing is need to replace damaged situation. During regular maintenance downtime time replacement bearings than the array bearing damage of selected into a sudden stop loss is much more economical. 3. It is important to check the bearing lubricant lubricant is not only in view of the bearings, also for all the import bearings. But please note that the bearing should not add too much grease. And then replace the bearing lubricant. Use after xie used engine oil, engine oil lubrication bearing if possible, should be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. And the use of grease lubrication bearing in replacing grease, Joe used in addition to the device should be avoided with cotton material come into contact with any part of the INA bearing. Because these residues fiber may wedged in between the scroll and damage, especially the application of bearing more need to pay attention to this problem.
