In daily production, attention should be paid to monitoring the operation of the ball mill bearings, and planned repairs before the ball mill bearings fail, which can achieve twice the result with half the effort. At the same time, following reasonable processes, using efficient repair equipment and tools, and obtaining help from professional bearing factories will help improve the economic benefits of the enterprise. Reasons for the rise in bearing temperature
The bearing cooling water is interrupted.
Deterioration of quality, the oil itself is not clean or the oil deteriorates during operation. For example, the increase in moisture in the oil will cause the acidity of the oil to increase, which will reduce the lubrication effect of the oil, cause the bearing bush to be corroded, and cause the bearing temperature to rise.
Elephant
Alarm bell rings
The water wheel mechanical failure light plate on the side panel lights up, the temperature of the instrument indicating the bearing temperature rises, and the signal relay operates.
The black needle of the dial (expansion thermometer) coincides with or exceeds the yellow needle.
A fault signal indicating that the bearing temperature has increased.
Principle
When the bearing temperature rises, first determine whether it malfunctions. If it does rise, the following treatment should be done
Check whether the cooling water pressure, water flow and piping system are normal. If the water pressure is low, it may be that the filter is clogged. If it cannot be processed in time, it can be shut down for processing. When it is confirmed that it can work, it can be put into use again.
Check the oil pressure of the governor. If the oil pressure is low, it may cause the cooling water hydraulic valve to close.
Check whether there is any abnormal noise in the bearing, and detect whether there is any abnormality in the bearing swing.
Observe the oil sample to see if there is any change in oil color, and conduct tests to see if it has deteriorated. If deterioration is confirmed, the machine should be shut down and replaced with new oil.
Check whether the oil level on the oil gauge is normal. If not, check whether the oil tank drain valve is closed tightly. If it is closed tightly, the oil should be replenished. If the sealing gasket leaks oil, the machine should be shut down for treatment.
