In the use of centrifugal fans, blade wear often occurs. How to improve the wear of centrifugal fans? The following are some anti-wear measures that can be used for centrifugal fans according to different forms of wear:
1. Treat the blade surface: Carburizing, plasma surfacing, spraying cemented carbide, and pasting ceramic sheets can be performed on the blade surface. All of these methods can increase the hardness of the blade surface to a certain extent, thereby improving the wear resistance of the blade, but various treatment processes have certain difficulties, difficult operation or high price factors reduce the feasibility of blade treatment.
2. Spraying wear-resistant coating on the surface: This method is recommended, it is simple to operate and the cost is not high, but the coating wears quickly, and it takes about 3-5 months to re-spray the surface wear-resistant coating .
3. Improve the blade structure: The wear can be reduced by modifying the blade structure, such as processing the blade working surface into a serrated shape, changing the hollow blade into a solid blade, and adding welding wear blocks to the blade.
4. Front anti-wear cascade: After installing the anti-wear cascade at the most easily worn place, it can prevent the particles from flowing to the rear disc and the blade root, thereby converting the concentrated wear of the particles into uniform wear and improving the wear resistance of the impeller. properties and prolong the service life of the fan.
5. Use a high-efficiency dust removal device: 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 purify the working environment of the fan to reduce the wear of the centrifugal fan.
The wear condition of the centrifugal fan directly affects the working efficiency and service life of the centrifugal fan, so it is very necessary to take anti-wear measures for it. I hope these anti-wear measures provided by Xiaobian can help you.
