How to prevent corrosion of cooling fan?
Cooling fans are used in industrial production, mainly for heat dissipation, cooling and dust removal for large-scale production equipment. The general industrial production environment is more complicated. In order to extend the service life of the cooling fan, it needs to do some treatment, such as the most common anti-corrosion. Last time, I also introduced the reason for the oil leakage and oil rejection of the cooling fan. Today I will introduce how to prevent the corrosion of the cooling fan?
1. Surface treatment of cooling fan
The surface protection treatment of the cooling fan is usually carried out by methods such as zinc plating, chrome plating, and chemical plating. These methods are effective in many environments, but for rotating parts, you need to choose carefully, because the base material and the coating are two kinds of materials, and their linear expansion coefficients are different, which will produce different shapes when the rotating parts are elastically deformed. The amount of deformation, resulting in a large number of micro-cracks, will accelerate the formation of corrosion. Therefore, we need to choose appropriate materials and processes according to the actual use environment.
2. Cooling fan design
The design of the cooling fan is the performance of its core technology, which affects the service life of the fan and ensures the safety of the fan. The structural design of the cooling fan, the design defects that are most likely to accelerate corrosion are the stress concentration tendency and the gap environment. Sometimes, although the corrosion rate is small in the metal immersion solution, the gap is formed because the chemical and electrochemical state of the internal solution has changed It will cause severe crevice corrosion and requires careful design.
3. Material of cooling fan
The materials used for different cooling fans are different, and the anti-corrosion effect is also different. After selecting the cooling fan model, according to the corrosion resistance of different materials in different environments, the main application environment, working strength and many other factors, the strength parts materials are determined from the basics. From the perspective of the material itself, the target material it targets is safe.
How to prevent the cooling fan from corrosion is introduced here today. The anti-corrosion effect of the cooling fan can maintain the aesthetic appearance of the fan, reduce environmental pollution, and effectively extend the service life of the fan. It saves equipment costs for the enterprise and requires careful selection when purchasing a cooling fan.
