The high bearing temperature is a common and dangerous damage to the rotating equipment, which will reduce the service life of the bearing and increase the maintenance cost. Therefore, it is the guarantee for the continuous and safe operation of the equipment to quickly determine the cause of the fault and take appropriate measures to solve it.Henan Weichuang Bearing Precision Technology Co., Ltd is always willing to be at your service.
When the bearing temperature is high, the problem should be solved from the following aspects:
1) The amount of fuel is not appropriate
The bearing housing should be refueled regularly as required by the job. After the bearing is refueled, sometimes the temperature will be high, mainly due to excessive refueling. At this time, the temperature continues to rise. After reaching a certain point (generally about 10 ° C ~ 15 ° C higher than the normal operating temperature) will remain unchanged, and then gradually decline.
2) The grease added to the bearing does not meet the requirements or is contaminated
Appropriate grease should be used. The bearing box and bearing should be cleaned during maintenance. The fueling pipeline should be checked and unblocked. Different types of grease should not be mixed. If other types of grease are replaced, the original grease should be cleaned first; Add grease, grease should be properly kept to prevent moisture and dust.
3) Insufficient cooling
Check if the pipeline is blocked, whether the inlet temperature and return water temperature exceed the standard. If the cooler is not suitable for use and the cooling effect is poor and cannot meet the requirements for use, it should be replaced in time or a new cooler installed in parallel. The axial flow induced draft fan should also check the insulation and sealing of the core barrel.
4) Confirm that there is no such problem and then check the coupling alignment and bearing
The alignment of the coupling must conform to the process standard. In the case of axial flow induced draft fans, hydraulic couplers, etc., the problem of thermal expansion of the equipment during operation should also be considered. The impeller side of the induced draft fan expands due to heat, and the bearing box rises. When the temperature of the hydraulic coupler increases, the bearing housing expands and the bearing rises. Therefore, the timing of the motor should be higher. The size of the reserve should be based on the characteristics of the equipment. Depending on the temperature parameters in operation.
