1. Material selection of suction filter cooling fan
There are many materials for the production of suction and cooling fans, but some materials are prone to chemical substances that cause pitting and cause erosion. When selecting materials, one should consider whether the centrifugal fan has strong corrosion resistance, plasticity, easy processing, and stable temperature resistance.
2. Take precautions for maintenance on the surface
This is the basic way to prevent and alleviate the erosion of centrifugal fans. Generally, manufacturers often use the surface treatment of the suction and cooling fan in the design plan. The surface treatment methods are hot-dip galvanizing, organic chemical spraying, bosses, etc. . Specifically, the surface treatment method can be selected according to the nature of the material used. After the surface treatment, the natural environment can be protected from erosion.
3. Overall design
When designing a centrifugal fan, in the structural layout, the conceptual defect that can alleviate corrosion is the combination of ground stress and the gap standard. According to actual use cases, it is found that a reasonable structure can effectively alleviate the erosion rate and prolong the service life.
