The underground mining axial flow fan bearing temperature is a critical indicator of the fan’s health and operation. A high underground mining axial flow fan bearing temperature can signal mechanical problems and safety risks that must be addressed immediately to avoid equipment failure.

One common reason for high bearing temperature is insufficient lubrication oil. When the oil level is too low, friction increases, causing the bearing to overheat. It’s essential to check the oil station regularly and ensure the oil quantity meets the required level.

Another possible issue is high lubricant oil temperature. If the cooling water system or cooler malfunctions, the oil can’t dissipate heat effectively, leading to a rise in bearing temperature. Inspect the cooling system to confirm it’s operating properly.

Poor lubricant quality is also a contributing factor. Overused or degraded oil and grease lose their protective qualities. Regularly replace oil and grease and conduct periodic oil analysis to maintain optimal lubrication.

Bearing failure is another major cause. Worn or damaged bearings increase resistance and generate excess heat. If this is the case, the only solution is to replace the bearing.

Sometimes, the problem lies not in the bearing itself but in the temperature sensor. A faulty or inaccurate sensor can display false high readings. Calibrate the sensor and replace any defective units to ensure accurate monitoring.

Finally, incorrect bearing clearance can cause the bearing to overheat. If the clearance is too tight or too loose, friction increases. In this case, adjust the clearance or install a new bearing that meets the design specifications.

In conclusion, if the underground mining axial flow fan bearing temperature is too high, it is essential to check lubrication levels, coolant systems, lubricant quality, and bearing conditions. Also, verify the temperature sensor and bearing clearance. Regular maintenance and proper inspection will help reduce downtime and extend the service life of underground ventilation equipment.
