Do you know how to mitigate corrosion problems of industrial centrifugal fans?

How to effectively alleviate the corrosion problem of industrial centrifugal fans? There are many kinds of corrosion damage forms of industrial centrifugal fans. The causes of metal corrosion are not the same under different environmental conditions, and the influencing factors are also very complex. In order to prevent and slow down corrosion damage, corrosion process is blocked and controlled by changing some conditions and influencing factors.

The following is an analysis of the anti-corrosion problems of industrial centrifugal fans:

1, choose the correct material of centrifugal fan: different materials and separation requirements, need to choose different models. After the model and parameters are determined, according to the corrosion resistance of different materials in different environments, comprehensive physical and chemical properties, cost performance and many other factors, so as to determine the strength, parts, materials on the basic level.

2. Complete design of centrifugal fan mechanism: a good design can prolong the service life of the equipment and ensure the safety of the equipment. For traditional structural designs, design defects that tend to accelerate corrosion are stress concentration tendencies and crevice environments, sometimes despite metal immersion solutions, where corrosion rates are low. However, the formation of cracks, due to the chemical and electrochemical state of the internal solution changes, will cause serious corrosion.

3. Isolation of corrosion environment: In the design of centrifugal fans, surface treatment methods are often used, such as flange, galvanized, chromium plated, chemical coating and so on. These methods are effective in many environments. But for rotating parts, it is necessary to consider the linear expansion coefficient of substrate material and coating.
