Bearing the percentage of the damaged reasons and repair the pump bearing wear case - bearing knowledge

Bearing as important components in the equipment, the use of equipment efficiency has played a crucial parts, bearing damage is a common problem, however, also has a lot of cause of bearing damage, the bearing network according to the understanding of the bearing use, overall, the percentage of the statistics result in bearing damage reason, hope everybody helps. Bearing the percentage of the damaged reasons: 1, poor lubrication, Accounts for about 38%) , poor lubrication is one of the leading causes of premature failure of the bearing. Main causes include: (1) failure to refill lubricant or lubricating oil; (2) the lubricant or lubricating oil filling in place; (3) lubricant or improper selection of lubricating oil, lubrication method is not correct; (4) seal damage, causing the lubrication failure. 2, lubrication, pollution, Accounts for about 24%) , pollution can also cause premature bearing damage, pollution refers to such as dust, scrap metal, or other material into the inside of the bearing. Main causes include: (1) early to open the bearing packing before use, cause pollution; (2) the installation work environment is not clean, cause pollution; (3) bearing working environment is not clean, working medium pollution, etc. (4) thin oil lubricating oil filter damage or failure to replace the oil filter. 3, improper installation, Accounts for about 18%) Use brute force: (1) when installation, directly with a hammer percussion bearing to bearing damage, the largest is the main cause of deformation; (2) the installation does not reach the designated position, install a deviation or failure to the bearing, bearing clearance is too small. Inside and outside the circle is not in the same center of rotation, resulting in different heart. (3) bearing free side without axial moving clearance, bearing large axial force overload damage. 4, metal fatigue ( Accounts for about 15%) Common fatigue failure reasons might be: bearing overload operation for a long time, did not change in time, equipment aging, etc. 5, bearing quality problem ( 4%) , many of them are on the market now 'treasures outside its, defeat garrulous among them', many companies tend to focus on the price when purchasing, do not take the quality, procurement to inferior bearings are often not take long before will be damaged. 6 and other uncertain factors, 1%) The percentage damage reason, mainly is for bearing the early damage to analyze the condition of the bearing damage factors are various, sometimes bearing damage may be integrated and cause, we need according to the concrete damage, then the correct analysis of the bearing damage factors, so as to find a better solution. China bearing network also share the pump bearing wear after repair case, hoped everybody can have a preliminary understanding of the process. 1. Into the scene, first measurement size to verify whether consistent with the drawings, to ensure that the repair precision, after verification, size is consistent with the drawings; 2. With oxygen acetylene surface oil removal, then grinding to repair, ensure the rough surface in order to increase the cohesive force; 3. Anhydrous ethanol cleaning repair surface; 4. In proportion to reconcile sauvy SD7101H carbon nano polymer materials, harmonic until evenly colorless difference; 5. The harmonic good SD710H daub on the repair, installation tools in place; 6. Heat curing, and improve the material performance and speed up the material curing time; 7. Remove the tooling, check fix size, bearing assembly, when confirmed after repair, 6 hours when sharing; 8. Back to install equipment smoothly after boot, various parameters to normal.
