Anti corrosion measures of centrifugal fan
1.It is important to choose the material for the fan.
In the process of making centrifugal fan, its different materials and separation requirements can be selected for different models. After determining its model and main parameters, it will be effective according to the corrosion resistance of different materials in different environments. The physical and chemical properties, cost-performance ratio and other factors are synthesised to determine the strength part materials from the fundamentals. From the point of view of the material itself, it is aimed at the target material is safe.
2. Structure Design of centrifugal Fan
In general, a good design can extend the service life of its equipment to a certain extent, so as to ensure the safety of its equipment.
3. Surface Protection measures of centrifugal Fan
One of the basic ways to control the corrosion of centrifugal fan is to isolate the corrosive environment. In the design, surface treatment methods, such as flange, galvanizing, chromium plating, chemical coating, etc., are often used. These methods are effective in many environments, but for rotating parts, it is important to pay attention to the fact that substrate and coating are two kinds of materials, and their linear expansion coefficients are different. Different amount of deformation will be produced in elastic deformation of rotating parts, resulting in a large number of micro-cracks. If the above phenomenon exists, corrosion will be accelerated. Therefore, the surface protection of rotating parts should be carefully used.http://www.jnblower.com/
