Centrifugal fans will experience roller wear during application, so how to avoid them? Centrifugal fan manufacturers detailed their anti-wear countermeasures:
This type of method is more popular. It is easy to use and low in price, but the coating wears quickly, and the surface wear-resistant coating must be applied again around 3-5 months. While using a mini centrifugal fan, it is very important to protect the surface.
Carburizing, plasma surfacing, spray-painting of cemented carbide, bonding ceramic sheets, etc. can be carried out on the surface of the leaves. This kind of method can increase the hardness of the leaf surface layer in the corresponding layer, and then improve the wear resistance of the leaf, but it is difficult to operate in various processes or the high price factors reduce the feasibility analysis of the disposal of the DC centrifugal fan leaf.
It can be reduced by the wear of the blade, such as the change of the structure of the blade processed into a serrated surface, the hollow leaf becomes a solid leaf, and the leaf is welded with a wear gauge block or the like.
After installing the anti-wear cascade at the most vulnerable part of the DC centrifugal fan, the particles can be prevented from flowing to the rear wheel and blade roots, and the concentrated abrasion of the particles can be converted into uniform abrasion, improving the wear resistance of the impeller and prolong the service life of the centrifugal fan. As a reliable cooling fan supplier, WHEE pays much attention to offer good quality centrifugal fans with long service life.
The dust in the operating environment of the centrifugal fan will also increase the wear of the fan. It is recommended to use a dust removal device to clean the working site of the centrifugal fan to reduce the wear of the centrifugal fan.
