Treatment Measures of Bearing Temperature Rise of Rotary Kiln

Rotary kiln mainly by the cylinder, transmission, support device, wheel device, kiln head, kiln tail, kiln seal and kiln hood and other components. The roller support device carries the weight of the entire kiln body, and play a role in positioning the cylinder, it is safe and smooth operation. Rotary kiln wheel rise is a common phenomenon in the work of the temperature, causing more reasons, if the treatment is not timely, it may cause serious consequences.

Common causes of bearing temperature rise and treatment measures:
1. Due to lubricating oil causes the temperature of the wheel
Do not change tire wheel lubricants or maintenance for a long time, causing the viscosity of lubricating oil, oil emulsification, oil containing dust and other impurities, can cause bearing pads fever. Only to make regular replacement of new oil, strengthen the daily maintenance of the wheel bearing pad, in order to effectively prevent the lubrication caused by the roller wheel temperature phenomenon.
2. The wheel pressure and lubricating device shedding caused by the bearing temperature rise
If the roller shaft seal is damaged, there is oil leakage phenomenon, so that the oil level is reduced, or lubricating oil spoon off will cause the bearing temperature. So be sure to do the daily inspection of the wheel seal, the timely replacement of seals, fastening lubrication spoon.

3. Water cycle system failure
If the circulating water system cannot get clean up for a long time, the pipeline will be clogged, resulting in poor circulation of circulating water or less and cause the bearing pad heat; when the internal circulation pipe rupture water leakage, the viscosity of the lubricating oil destruction, so that oil quality deterioration, bearing temperature rise. The treatment measures are: pickling the circulating water pipe, remove the internal oil impurities, replace the damaged internal water pipes.

4. Due to small openings causes the gap temperature rise
Wheel contact pad is used for a long time, the contact angle between the tile and the shaft will be more and more bigger, while the gap between the mouth and the shaft is getting smaller and smaller, to a certain extent, the oil cannot enter the bottom of the bearing lubrication, causing the bearing temperature rise. Found that the gap is small, should be promptly repaired, re-open the mouth, the general gap is 0.003Dmm tile (D for the diameter of the wheel shaft).

The temperature of the handle wheel is very sudden. To face this sudden thermal phenomenon, temporary looking for tools is very troublesome, looking for a long time, may miss the best time to deal with the temperature rise, causing serious consequences. So the operator need to ready to handle some special tools for the temperature of the roller, and to develop an effective contingency plan, the only way to solve the problem in the event of faults, the maximum guarantee of production Normal, to reduce the loss of failure.
