Rotary kiln in the production process, the carrier axle tile will make some noises, this sound is not normal to find the cause of the need for timely solution. Cause this problem occurs more reasons, by the roller caused by excessive force; caused by the result of poor lubrication; bush by the result caused by poor maintenance quality. Here to talk about this as the cause of poor lubrication and treatment methods: 1. Bearing lubricant used improperly, oil viscosity is not enough, the film is too thin to form, resulting in between the shaft and the tile is still a greater friction. At this point, should be replaced immediately higher strength lubricants. (2) When the rolling ring material near the kiln discuss worn thin, it will produce local temperature radiation to the bearing, the lubricant stiffness becomes low, the film thinning, between the shaft and the tiles are not good lubrication. At this point, you should temporarily higher viscosity oil change and increased insulation measures. 3. Bearing long-term interruption of cooling water, its temperature rises, undermining the lubricant viscosity. At this point, you should immediately seek to restore cooling water. Smooth. And replace with new oil. 4 low temperature in winter, due to the replacement of the oil is not running on a seasonal varieties regime, high viscosity lubricant inside the bearing, poor mobility, and even produce clotting, so bearing in starvation state. At this point, you should promptly change winter lubricants. And remove the heat shield on the bearings, increasing kiln body radiation temperature of the bearing. 5 climbing kiln playing a long time, but the speed is low, so that the roller bearing oil to bring the oil is too small spoon, can not meet the lubrication between the axis and tile needs. In this case, the temporary artificial fuel, and timely contact with the workers to see the fire, making kiln speed control 20r / h or more. 6 tablespoons oil when the bearing failure or automatic sump plug or oil level is too low, resulting in reduced lubrication, should be promptly repaired or supplemented with new oil. Above this six o'clock to find out why that is, and also gives a solution to the problem, but also to need to think about a problem, Rotary Kiln in the lubrication needs attention to what things? 1 Select the proper lubricant is very important. (2) on the inference of the lubricant timely inspection, periodic refueling, replace with new oil. 3 for the different seasons, the replacement of different lubricants. 4 in the replacement of oil at the same time, for the kiln operation is also very important and need to work in close coordination with the kiln. 5, for the prop shaft oil Vaga place, if there is a malfunction of the device, the need for timely repair, and quality assurance.
