The percentage of bearing damage reason and repair the pump bearing wear

Bearing as important components in the equipment, the efficiency of the use of the equipment has played a vital part, but bearing damage is a common problem, cause the cause of the damage of bearing are also many, the net on the basis of understanding on the use of the bearing, bearing on the whole, the statistics from the percentage of bearing failure reason, hope everybody to help. The percentage of bearing damage reason: 1, smooth bad ( Accounts for about 38%) Smooth, bad is one of the main reason of premature bearing damage. Main reasons include: (1) failure to smooth filling agent or smooth oil; (2) the smooth agent or smooth oil not filling in place; (3) smooth agent or improper selection of smooth oil, smooth way is not correct; (4) seal damage, smooth from failure. 2, smooth 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 reasons include: (1) apply early to open the bearing before packing, formation pollution; (2) when the device working environment is not clean, formation pollution; (3) bearing working environment is not clean, working medium pollution, etc. (4) smooth thin oil oil filter damage or failure to change the oil filter. 3, improper device ( Accounts for about 18%) When: (1) device using a brute force, directly with a hammer percussion bearing to bearing damage, the largest is the main reason of forming deformation; Device (2) does not reach the designated position, is biased or not installed to the bearing, bearing clearance is too small. Inside and outside the circle is not in the same rotation center, forming different heart. (3) bearing side without axial channeling clearance, bearing accept large axial force overload damage. 4, metal fatigue ( Accounts for about 15%) Common fatigue damage reason may be: bearing long-term overload operation, failed to timely change, equipment aging, etc. 5, bearing quality problem ( 4%) , many of them are on the market now 'treasures outside its, defeat garrulous among them', many enterprises procurement often only focus on the price, do not pay attention to quality, procurement to inferior bearings are often not take long before will be damaged. 6, other (not sure elements such as 1%) The percentage damage reason, mainly is for bearing the early damage situation to analyze, bearing damage factor is various, have bearing damage in comprehensive reason may be incurred, we need according to the damage situation in detail, and then correct the anatomy of the bearing damage elements, such ability find a better treatment method. 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, the first measurement can verify the size and drawings, to ensure that the repair precision, after verification, the size and drawings differences; 2. Oil removal with oxygen acetylene appearance, then grind to repair, to ensure that the rough appearance in order to increase the cohesive force; 3. Anhydrous ethanol cleaning repair appearance; 4. In proportion to reconcile sauvy carbon nano polymer materials SD7101H, harmonic until average colorless difference; 5. The harmonic good SD710H daub on the repair, installation tooling in place; 6. Heat curing, progress data performance and speed up the curing time; 7. Remove the tooling, verify size of repair, after bearing assembly, repair, and the end of 6 hours when sharing; 8. Back to install equipment smooth start up, after the end of each parameter is normal.
