How to make the cooling fan extend the service life?
As the name suggests, the cooling fan is mainly used for cooling and cooling various equipments. It is mainly used in industry. The general industrial environment is relatively complicated, so it is often necessary to do some treatment on the cooling fan to avoid corrosion. This is also to extend The life of the equipment reduces costs. What is the main job?
1, cooling fan surface treatment
The surface protection of the cooling fan is usually carried out by galvanizing, chrome plating or electroless plating. These methods are effective in many environments, but for rotating parts, careful selection is required because the base material and the coating are two materials, and the coefficient of linear expansion is different, which will be different when the rotating member is elastically deformed. The amount of deformation, which causes a large number of microcracks, will accelerate the formation of corrosion. Therefore, we need to choose the right 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 defect that is most likely to accelerate corrosion is the tendency of stress concentration and the gap environment. Sometimes, although the corrosion rate is small in the metal soaking solution, the gap is formed, and the chemical and electrochemical states of the internal solution change. It will cause severe crevice corrosion and requires careful design.
3, cooling fan material
The materials used in different cooling fans are different, and the anti-corrosion effect is different. After selecting the cooling fan model, the strength component materials are determined from the basic surface according to various factors such as corrosion resistance of different materials in different environments, main application environment, work intensity and the like. From the material itself, the target material it targets is safe.
