Key points for lubrication in axial fan maintenance

Feb 10, 2025

1. Choose the right lubricant
When lubricating and maintaining the axial fan, it is necessary to choose the right lubricant to ensure that the quality of the lubricant meets the requirements. Common lubricants include engine oil, grease and bearing oil, etc., which can be selected according to the model and operating conditions of the axial fan.

2. Regularly lubricate
The axial fan runs at a high speed and generates a lot of heat from friction, so it needs to be lubricated regularly. Generally speaking, lubrication is required every 100-200 hours of operation. If the lubricant is found to be ineffective or seriously contaminated, it needs to be replaced in time.

3. Control the amount of lubrication
During the process of lubrication, the amount of lubricant needs to be controlled to avoid over-lubrication and under-lubrication. When refueling, the lubricant should be slowly injected into the bearing until the lubricant flows out of the oil outlet of the bearing.

4. Regularly replace the lubricant
During the use of the axial fan, the lubricant will continue to fail and be contaminated, so the lubricant needs to be replaced regularly to avoid affecting the normal operation of the axial fan. It is generally recommended to replace the lubricating oil once a year. In special cases, the replacement interval can be appropriately extended or shortened according to the actual situation.

5. Pay attention to the quality of the lubricating oil
The quality of the lubricating oil is directly related to the operating stability and life of the axial flow fan. Therefore, it is necessary to regularly test the quality of the lubricating oil and replace and adjust it in time if problems are found. At the same time, in the process of storing the lubricating oil, pay attention to moisture, heat and sun protection to avoid affecting the quality of the lubricating oil.

For the maintenance of the axial flow fan, it is essential to correctly select the appropriate lubricating oil, regularly refuel and lubricate, control the amount of refueling and lubrication, regularly replace the lubricating oil and pay attention to the quality of the lubricating oil. Only by properly maintaining the axial flow fan can it be ensured that it can operate stably for a long time and play a better effect.
