Causes and Solutions of FAG Cylindrical Roller Bearings Overheating
Recently, a customer reported that the temperature of the fag bearing.com/cylindrical-roller-bearings.html' target='_blank'>cylindrical roller bearing is too high. Our technicians said that it is a common phenomenon when the bearing temperature is too high. The key is that we need to know the reason for the heating of the fag cylindrical roller bearing. phenomenon, and then find solutions and solutions. The following is a brief introduction to the causes and solutions of excessive bearing temperature. The phenomenon that the temperature of fag cylindrical roller bearing rises (1). There is an alarm bell. (2). The light plate of the mechanical fault of the water wheel on the side of the machine is on, the temperature of the instrument indicating the bearing temperature rises, and the signal relay operates. (3). The black needle of the thermometer disc (expansion thermometer) coincides with the yellow needle or exceeds the yellow needle. (4). Send out a fault signal that the bearing temperature rises. The reasons for the temperature rise of fag cylindrical roller bearings (1). The cooling water of the bearing is interrupted. (2) The oil quality is deteriorated, the oil itself is not clean or the oil is deteriorated during operation. For example, the increase of water in the oil will cause the acidity of the oil to increase, which will reduce the lubricating effect of the oil, cause the bearing bush to be corroded, and cause the bearing temperature to rise. Treatment of temperature rise of fag cylindrical roller bearing When the bearing temperature rises, first determine whether it is malfunctioning. If it does rise, the following measures should be taken: (1). Check whether the cooling water pressure, water flow and pipeline system are normal. . If the water pressure is low, it may be that the filter is blocked. If it cannot be handled in time, it can be stopped for processing. When it is confirmed that it can work, it can be put into use. (2). The oil pressure of the governor should be checked. If the oil pressure is low, the cooling water hydraulic valve may be closed. (3). Check whether there is abnormal noise in the bearing, and check whether the bearing swing is abnormal. (4) Take oil samples to observe whether the color of the oil has changed, and conduct tests to see if it has deteriorated. If it is confirmed that it is deteriorated, it should be stopped and replaced with new oil. (5) Check whether the oil level of the oil mark is normal. If it is abnormal, check whether the oil drain valve of the oil tank is closed tightly. If it has been closed tightly, it should be replenished with oil. If the sealant gasket sees oil, it should be stopped. When we are using the fag cylindrical roller bearing, if it is found that the temperature is very high, we should stop the operation of the equipment quickly, then find out the reason, and deal with it according to the solutions provided above, but it may be caused by the heating of the bearing. The reasons are different, so the solutions are also different, so it is still necessary to deal with specific situations and complete them with the help of technical personnel.
