If the cooler is not properly selected and the cooling effect is poor, and cannot meet the requirements of use, it should be replaced in time or a new cooler should be installed in parallel. Therefore, to quickly determine the cause of the failure and take appropriate measures to solve it is the guarantee for the continuous and safe operation of the equipment.High bearing temperature is a common and harmful fault of rotating equipment, which will reduce the service life of bearings and increase maintenance costs.
The grease added to the bearing does not meet the requirements or is China roller bearings manufacturers contaminated The selection of lubricating grease is improper, it is not easy to form a uniform lubricating film, and it cannot reduce the friction and wear inside the bearing. The axial flow induced draft fan should also check the insulation and tightness of the core tube. When the fit is too loose, relative sliding of the mating surface will be called creep.
The size of the reserve depends on the characteristics and Depending on the temperature parameters during operation. 3) Not enough cooling Check whether the pipeline is blocked, whether the inlet oil temperature and return water temperature exceed the standard. This is an important basis for judging the cause of bearing damage.
The lubrication is insufficient and the bearing temperature rises. Economic benefits have a great impact.. At the same time, the clearance is too small, the oil volume will be reduced, too late to take away the heat generated by friction, which will further increase the temperature rise of the bearing .
Secondly, check the bearing for bite damage and wear; check the surface finish of the inner and outer rings, rolling elements, and cage of the bearing as well as whether there are defects such as cracks, rust, peeling, pits, overheating and discoloration, and measure whether the bearing clearance exceeds the standard; check Whether the shaft sleeve is worn, pits, peeling, if any of the above conditions should be replaced with new bearings. Common causes of excessive bearing temperature
