Cooling fans are used in industrial production, mainly for large-scale production equipment to do cooling and dust removal work. The general industrial production environment is more complicated. In order to prolong its service life, the cooling fan needs to do some treatment.Such as the most common anti-corrosion. For example, what is the reason for the oil leakage and oil rejection of the cooling fan? Today, I will introduce how to prevent corrosion of the cooling fan?
The surface protection treatment of the cooling fan is usually carried out by zinc plating, chrome plating, chemical plating and other methods. These methods are effective in many environments, but for rotating parts, care needs to be taken because the base material and the coating are twoThe linear expansion coefficient of the material is different, which will produce different deformation when the rotating part is deformed elastically, resulting in a large number of micro cracks, which will accelerate the formation of corrosion. Therefore, we need to choose the right material according to the actual use of the environmentQuality and process.
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 most likely to accelerate corrosion design defects are stress concentration tendency and crevice environment, sometimes although.In the metal immersion solution, the corrosion rate is small; but the formation of cracks, due to the change of the chemical and electrochemical state of the internal solution, will cause serious crevice corrosion, which needs 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, work intensity and many other factors, from the fundamentalsDetermine the strength part material. From the point of view of the material itself, the target material it targets is safe.
The above is how the cooling fan anti-corrosion knowledge sharing.
