1. Material selection of suction filter cooling fan
There are many materials for the production of suction filtration cooling fans, but some materials are prone to chemical substances to produce tiger's dens, thereby causing corrosion. When selecting materials, it should be considered whether the corrosion resistance is strong, the plasticity is strong, the processing is easy, and the temperature resistance is stable.
2. Take maintenance and preventive measures on the surface
This is the basic way to prevent and alleviate corrosion. Generally, manufacturers often use the surface treatment of the suction filter cooling fan in the design scheme. The surface treatment methods are hot-dip galvanizing, organic chemical spraying, bosses and so on. Specifically, the surface treatment method can be selected according to the properties of the materials used. After the surface treatment, it can protect against corrosion from the natural environment.
3. Overall Design
When designing centrifugal fans, in the structural layout, the conceptual defects that can alleviate corrosion are the combination of ground stress and void standards. According to actual use cases, it is found that a reasonable structure can effectively alleviate the corrosion rate and prolong the service life.
