Preheater fan bearing wear how online repair

Preheater fan, one of the most common equipment in cement enterprises. Thought unceasingly, the energy consumption of cement consumption enterprise is the national economy, in the consumption of cement, the motor load power consumption capital accounted for nearly 30%, and drag the fan with high voltage motor, which holds a large proportion in the motor on a cement consumption line with 25% ~ 30% of electricity is used for drag type fan on each type. Grinding materials such as preheater bag dust collecting of exhaust fan, exhaust fan, exhaust fan, electrical dust collector at kiln head pulverized coal mill fan, cement grinding cycle fan, cement mill classifier deduster main exhaust fan, etc. Preheater fan in the long run, bearing a metal fatigue, mating surface of bearing inner ring and the shaft by interference fit into a clearance fit. Long run due to found it in a timely manner to incur in the process of the relative displacement of bearing inner ring and shaft appear to cause bearing a aggravate wear appearance. Bearing running the inadequate care at the same time also cause bearing wear one of the main reason. In short form bearing damaged elements is more, once the onset of bearing problems, is bound to bearing with axial relative movement or the sintering in to damage, the shaft of the fan vibration if not found in time treatment of serious when they form or the external downtime and affect consumption. For the above situation, on the choice of restoration approach is more cautious. Sauvy carbon nano polymer technology application on the mechanical properties of the carbon nano polymer material characteristic and the corresponding repair process online repair including roller press, roller mill, blower, hoist, motor, reducer and other large axial of wear and tear. Repair process is simple: 'sauvy tooling repair process' first stop the disposal of the wear appearance, then put the carbon nanometer polymer materials applied directly to a specific part of the wear and tear, heat with repair tooling complete repair materials forming and stop after curing. Repair data size to the bearing design size, meet the elevator running in this part of the request. Sauvy industrial carbon nano polymer material similar to a cold welding technology, on-line repairing process does not produce high temperature, good maintenance equipment ontology is not damaged, and not be restricted by wear is in the process of repair. Polymer materials in the process of using carbon nanotubes will not produce metal fatigue wear and tear, in normal maintenance under the premise of care equipment, its use life and higher than that of the new parts after the restoration of life. Above all, sauvy industrial carbon nano polymer materials to repair all kinds of box body bearing chamber wear under repair with high efficiency, can be completed online repair, comprehensive repair capital is low, to the enterprise equipment maintenance maintenance provide powerful processing plan, reduce the consumption of the enterprise capital. The sauvy tooling repair process steps (1) & emsp; On the basis of axial fan drawings or measurement of shaft neck size processing corresponding tooling; ②  Application of tooling and shaft with the restoration of the journal of concentric; ③  Repair parts appearance oil removal, coarse grinding disposal; ④  Harmonic SD7101H data, and daub on repair parts; ⑤  Tooling wall brush SD7000; ⑥  Installation tooling shaft neck size; ⑦  Measurement of shaft neck size, heat load bearing.
