What is the anti-corrosion design of centrifugal fans? In addition, centrifugal fans may encounter corrosion problems after a period of use. Here is a detailed introduction:

Firstly, choosing the correct material for centrifugal fans is crucial, as different materials and separation require different models. After confirming the model and basic parameters, based on the corrosion resistance of different materials in different environments, combined with their physical and chemical properties, cost performance, and other factors, the strength component materials are determined from the fundamentals. From the perspective of the material itself, the target material is safe.

Secondly, the mechanism design of centrifugal fans can improve the service life of the equipment and ensure the safety of the machine

For structural design, design defects that are prone to accelerated corrosion are stress trends and gap environments. Sometimes, in metal immersion solutions, the gaps can cause severe gap corrosion due to changes in the chemical and electrochemical conditions of the internal solution.

3、 Surface protection measures for centrifuge

One basic idea of corrosion control is to avoid corrosive environments. In the design of centrifugal fans, surface treatment methods such as flanges, galvanizing, chrome plating, chemical coatings, etc. These methods are effective in many environments, but for rotating components, we must pay attention to an important condition: the substrate and coating are two materials with different coefficients of thermal expansion, which produce different deformations during the elastic deformation process of the rotating component, resulting in a large number of microcracks; If the above situation occurs, corrosion will accelerate.

The above is an introduction to centrifugal fans. The surface protection method for rotating components should be carefully selected.
