a paper mill currently has a total of 10 hot fans, it is inconvenient to refuel every day because of the high temperature, as well as grease loss is large. the u.lube team found that the bearings of the heaters are skf2315 bearings with shaft diameters of 75(id)and 160(od), respectively, and a speed of 2980 rpm. using a temperature gun to measure the bearing seat temperature of 140-150 ℃, the bearing seat temperature will rise to about 170 ℃ in the case of less normal work, according to this projection, the actual temperature of the bearing under normal circumstances should be 160-170 ℃, they currently using a brand of 220 grease, basically every day need to replenish the grease, from the scene, the environment is under dust, with grease loss and other phenomena.

润滑改良建议 suggestions for lubrication improvement
in response to the above problems, u.lube team suggests using suitable lubricants to lubricate the bearings, such as u.lube high-temperature bearing lubricant, and also regularly check the sealing of the bearings to avoid aging of the seals, etc. u.lube high temperature bearing lubricant improves the anti-wear bearing capacity of the oil on the basis of meeting the high temperature continuous operation of the hot fan bearing, and the improved lubrication can reduce the wear rate of the bearing, prolong the service life of the bearing, enhance the sealing of the bearing, improve the grease loss, improve the stability of the operation of the equipment, and reduce the maintenance cost of the equipment.
for the situation that the hot fan needs to be manually refilled with grease every day, u.lube team suggests using vmaxx single-point grease filler system to improve the production efficiency. in addition, after replacing the appropriate lubricant, the operating status of the hot fan should be monitored and fault diagnosed. through various advanced testing methods such as temperature monitoring, vibration analysis and oil testing of the equipment, we can master the operating status of the equipment, determine the parts and causes of faults and predict and forecast the future status of the equipment. this prevents equipment accidents and unplanned downtime, and improves the maintenance level of equipment.
