The motor bearing temperature is too high after oiling
Thread Content
The 6KV, 3000KW motor is lubricated according to the specified oiling schedule; as a result, its temperature rises sharply, reaching up to 94 degrees. This happens every time the oil is added, and the lubricant used is Mobil
Too many notes. . . . . . . . . .
For 6KV, 3000KW motors, there are usually specified requirements regarding the frequency of oiling and the amount of oil to be used, as well as the grade of grease to be applied. If the bearing temperature rises rapidly after applying the grease, it may be due to an excessive amount of grease being used. Check the amount of grease specified in the motor’s manufacturer’s instructions. Also, pay attention to keeping the grease applicator gun clean.
Too much oil is used; generally, two-thirds of the bearing chamber volume is sufficient.
If too much oil is applied, the high temperature can cause the oil to deteriorate; in such cases, the machine must be stopped to clean the bearings and lubricant must be added again. It is important to control the amount of oil used – generally, 1/2 of the capacity should be filled for two-pole motors, while 2/3 of the capacity should be used for motors with other numbers of poles. Regular oiling should also be done in appropriate amounts
It’s caused by too much oil being added, but the temperature can reach 94 degrees, so be sure to pay attention to that.
The initial amount of oil for a new bearing is generally 2/3； In the future, 1/2 of the bearing’s oil capacity will be sufficient.
You added too much oil, which caused compression inside. After running for some time, some of the oil was forced out; generally, bearings should be filled with half of their capacity in terms of oil
Impurities may enter during the oil filling process
One is excessive oiling, and the other could be wear of the bearing itself – that’s the problem
Too much oil has been added; please refer to the instructions, paying attention to the oil type and the amount of oil added each time.
