Cooling fan used in industrial production, mainly to large-scale production equipment to do the work of cooling, cooling and dust removal. General industrial production environment is more complicated, cooling fan in order to extend its service life, you need to do something about it, such as the most common anti-corrosion. What is the reason for everyone today how to introduce anti-corrosion cooling fan?
Cooling fan surface treatment
Cooling fan surface protection, usually using zinc, chrome, chemical plating and other methods. These methods are effective in many environments, but care must be taken with rotating parts because both the base material and the coating are of a different material and have different coefficients of linear expansion that will produce a difference in the elastic deformation of the rotor Deformation, resulting in a large number of micro-cracks, will accelerate the formation of corrosion. Therefore, we need to select the appropriate material and process according to the actual use of the environment.
Cooling fan design
Cooling fan design is the performance of its core technology, affecting the life of the fan to ensure the safety of the fan. Cooling fan structure design, the most easy to accelerate the design of corrosion defects are stress concentration and gap environment, and sometimes despite the metal immersion solution, the corrosion rate is small; but the formation of cracks, due to internal chemical and electrochemical state of the solution has changed, Will cause serious crevice corrosion, need careful design.
Cooling fan material
Different cooling fan selection of materials are different, anti-corrosion effect is not the same. Selected fan models, according to different materials in different environments, corrosion resistance, the main application environment, work intensity and many other factors, determine the strength of parts from the fundamentals of the material. From the material itself, it targets the target material is safe.
How to prevent corrosion on the cooling fan, introduced here today. Cooling fan anti-corrosion effect, you can maintain the fan aesthetic, reduce environmental pollution, and effectively extend the life of the fan, saving equipment costs for enterprises, the purchase of cooling fans need to carefully choose.
