Internal Friction Treatment and Protection Method for Axial Flow Fan

Release Time：2021-07-20

No matter how good the axial flow fan, there will be some problems after a long time. Here, let's talk about how to deal with the internal friction of the axial flow fan. To solve this problem, we must first understand what causes the internal friction of axial flow fans.
Due to the internal friction caused by the skew of the thrust bushing or wear, the skew of the axial flow fan impeller collides with the fan casing, or the friction caused by the casing not having good rigidity and shaking back and forth, and the friction caused by the skew of the fan impeller collides with the air inlet ring.
The principle of axial flow fan is that the rotor is transformed by the migration of electromechanical capability. At the same time, the volume of the closed cavity composed of rotor, stator, large and small end cover and sliding vane changes from small to large and from large to small due to the number of sliding vane sliding out. The atmosphere is sucked in when the volume cavity becomes larger and contracted when it becomes smaller, followed by the continuous torsion of the rotor, in order to achieve the atmosphere of continuous inhalation and austerity process, with other austerity situation analogy: the only realization of low speed pure reversal of the movement of the tightening process.
Axial flow fan The axial flow fan adopts the traditional and verified skills of the axial flow fan, and directly ends the drive at an abnormally low rate (1450rpm), which has incomparable reliability. The rotor is the only component that runs continuously. There are several grooves below that are inclined to cut along the length, and a sliding vane that can slide on the oil film is inserted in the axial flow fan.
The fixed position of the axial flow fan is to use the movement of the atmosphere, so how should we protect it.
1. When the axial flow fan is working, it is necessary to ensure that some equipment of the axial flow fan is operated in an abnormal environment, and to ensure that the axial flow fan is equipped in an abnormal use environment.
2, axial flow fan on the blades of axial flow fan dust, dirt should be eliminated on schedule, to ensure the stop of abnormal work.
3. It is necessary to reflect on whether the fan blades can be loose, and whether the gap between the blades and the wind simplicity is abnormal.
4. In the connection environment between mechanical and electrical equipment and chassis, there is also a reflection on whether the connection between the vibration damping seat and the foundation is complete or not.
5. At the end of the day is the result of changing grease for electromechanical bearings. The ordinary time is once every three months. You can also change grease according to the actual environment and the use of the environment.
