The causes of abnormally elevated bearing temperature are simple in terms of these categories: poor lubrication, insufficient cooling, etc.The centrifugal shaft is held out. If the temperature is due to the increased temperature caused by the suffering of bearing fatigue wear, the pits, and the increase in the gap, it can generally be judged by listening to the sound of the bearing and the measurement vibration.Its easier to judge.
1. Incorrect use of lubricant oil
(1) Is it appropriate to refuel?
Come on the bearing box according to the requirements of regular work.After the bearing is refueling, sometimes the temperature is high, mainly because of too much refueling.At this time, the phenomenon is continuously rising. After reaching a certain point (usually about 10 ° C to 15 ° C higher than the normal operation temperature), it will remain unchanged, and then gradually decreases.
(2) After confirming that there is no above problem, check the bearings box
Use winter oil in summer, use summer oil in winter, too much or too little oil will produce fever when the fan is running.When refueling, you must pay attention to the instructions of the bronnes or instructions for the refreshment of the fans to avoid this similar occurrence.
2. The cooling water is not invested or the flow is too small
The use of cooling water plays a particularly important role in rotating machinery operation.Before the fan runs, the first confirmation is whether the cooling water valve is turned on. After the opening, the flow of cooling water should be observed from the observation glass of the flower to ensure that this premise can start the fan.If the cooling water is not cast, the bearing will rise after a period of time running, and the bearings will be burned out in severe cases.
The above article is the reason and processing method of the abnormally increased temperature of the centrifugal aircraft bearing. If you still want to know and learn more about related knowledge, please pay more attention to us-
