What should I do if the bearing part of the vortex blower is hot?
When the vortex fan is running, it will generate a certain temperature. It has been said that the vortex fan is hot air, which is a normal phenomenon. However, if the local abnormal heat is generated, there is a certain problem. There are some reasons that can cause the temperature of the high-pressure fan to rise. It can be analyzed from the following points:
1. The lubrication quality of the bearing is poor. The purpose of lubrication is to prevent the moving and static parts from directly contacting the friction to form solid-liquid friction. If the amount of lubrication or quality is poor, the moving and static parts will be directly frictionally heated, otherwise the heat cannot be removed by lubrication and the bearing temperature of the high pressure fan will rise.
2. Rolling bearing assembly quality is poor. If the fastening force between the inner sleeve and the shaft is insufficient, the gap between the outer sleeve and the bearing housing is too large or too small.
3. The seal is too tight or the seal is too hot to cause heat.

4. The vortex fan bearing vibration is too large to withstand the impact load, which seriously affects the stability of the lubricating film.
5. The quality of the vortex fan bearing is poor. Sliding bearing scraping quality is not good, Wujin contact is not good or tires; rolling bearing rolling surface cracks, chipping, peeling, etc., will destroy the stability and uniformity of the oil film, the surface will make the bearing heat.
Generally speaking, the simplest and most direct way is to replace a bearing. How to replace the bearing of the vortex fan has a corresponding tutorial. For the manufacture of the bearing, you can see this video. How is the bearing of the vortex fan manufactured? There are usually two ways to seal the bearings. One is sealed and the other is steel. So what is the difference between this vortex fan bearing, and which bearing is suitable for use under any working conditions.
1. Rubber-sealed bearings: These bearings usually can not withstand particularly high temperatures and are suitable for use under normal conditions, but they have good sealing performance for air and are not easy to enter dust and other damage.
2, steel seal bearings: This type of bearings can withstand high temperatures, especially suitable for high temperature occasions, but the same, the sealing is slightly worse, according to different uses to choose the appropriate vortex fan bearings.
