Fan Bearing Overheat, Damage and Treatment Measures Usually the fan bearing temperature should not exceed 70 ℃, but in fact there are overheating conditions above this temperature. In order to solve this kind of problem, the following is to explain the different causes of overheating: Usually the fan bearing temperature should not exceed 70 ℃, but in fact there are overheating conditions above this temperature. In order to solve this kind of problem, the following is to explain the different causes of overheating: 1. Insufficient oil quantity, for which the following measures can be taken 1) When there are uneven levels in the oil pipeline, air should be fully extracted. 2) After the oil cooler is dirty, the cooling effect will be reduced, resulting in insufficient cooling oil. The cooler should be cleaned in time. 3) When the filter element is dirty, the element should be replaced. 4) When using oil ring bearings, use an oil level gauge to detect the oil level and observe whether the oil ring is running normally from the observation window. 5) In rolling bearings, overheating occurs due to insufficient grease or excessive filling. When adding grease, it is better to wipe off the original grease and replace it with a new one. Its dosage is suitable for nearly 2/3 of the space of the fan bearing box. 2. Poor oil quality selection When the oil quality does not meet the requirements or the quality is changed, it is also one of the reasons for overheating. The oil quality recommended by the fan manufacturer should be used. When changing the oil quality, it needs to be carefully studied before it can be used. In addition, the replacement standard of oil should be based on the degree of oxidation, viscosity, viscosity index, dirt degree, etc., and it is appropriate to formulate a rough standard.
