Vortex blowerWhat should I do if the bearing part heats up severely?
When the vortex fan is running, it will generate a certain temperature. As mentioned before, why is the vortex fan hot air? This is a normal phenomenon. But if there is abnormal local heating, it means that there is a certain problem. There are some reasons that can cause the temperature of the high-pressure fan to rise, which can be analyzed from the following points:
1. Poor lubrication quality of bearings. The purpose of lubrication is to prevent direct contact and friction between moving and stationary components, forming solid-liquid friction. If the lubrication amount or quality is poor, it will cause direct friction and heat generation between the moving and stationary components. Otherwise, the heat cannot be removed through lubrication and the temperature of the high-pressure fan bearings will increase.
2. Poor assembly quality of rolling bearings. If the fastening force between the inner sleeve and the shaft is insufficient, the gap between the outer sleeve and the bearing seat may be too large or too small.
3. Heating caused by tight sealing or excessive sealing components.

4. The bearings of the vortex fan vibrate excessively and bear impact loads, seriously affecting the stability of the lubricating film.
5. Poor quality of vortex fan bearings. Poor scraping and grinding quality of sliding bearings, poor contact or detachment of black metal; Cracks, fractures, peeling, etc. on the rolling surface of rolling bearings can damage the stability and uniformity of the oil film, causing the bearing to heat up.
In general, when these situations occur, the simple and direct solution is to replace a bearing. There are corresponding tutorials on how to replace bearings for vortex fans. For the manufacturing of bearings, you can watch this video "How to Manufacture Bearings for Vortex Fans". There are usually two sealing methods for bearings, one is rubber sealing and the other is steel sealing. So what is the difference between the bearings of this vortex fan and which bearing is suitable for use under what working conditions.
1. Rubber sealed bearings: These types of bearings usually cannot withstand extremely high temperatures and are suitable for use under normal conditions. However, they have good sealing performance against air and are not easily damaged by dust or other factors.
2. Steel sealed bearings: These types of bearings are resistant to high temperatures and are particularly suitable for high-temperature environments. However, their sealing performance is slightly poor. Therefore, it is recommended to choose the appropriate vortex fan bearing according to different applications.
