About the treatment of INA Roller bearing temperature rise
In order to extend its service life, we need to pay attention to many small details in daily use and maintenance, and better maintenance and maintenance of INA bearings.
The following phenomenon occurs when the roller bearing heats up
There are two cases in which the temperature rise of the roller bearing is relatively obvious:
1, there is an alarm ringing
2. Issue a fault signal that the INA bearing temperature rises.
3, the machine side water wheel mechanical failure light plate is bright, indicating the temperature of the roller bearing temperature of the instrument rises, the signal relay action.
4. Thermometer disk (inflated thermometer) The black needle and the yellow needle overlap or exceed the yellow needle.
When the roller bearing temperature rises, first judge whether there is a malfunction. If it does rise, it should be done as follows:
1. First check the water pressure of the cooling water, whether the water flow and the pipeline system are normal. If the water pressure is low, the filter may be clogged and cannot be disposed of in time. It can be shut down and put into use when it is confirmed that it can work.
2. The oil pressure of the governor should be checked. If the oil pressure is low, the cooling water hydraulic valve may be closed.
3. Check that the roller bearing has no abnormal sound, and check that the roller bearing swing has no abnormality.
4, take the oil sample to observe whether the oil color changes, and carry out tests to see if it deteriorates. When the deterioration is confirmed, stop replacing the new oil.
5. Check the oil level of the oil level. If it is not correct, check if the oil drain valve is closed. If it is closed, the oil should be shut down if there is leakage of the gasket.
