What matters should be paid attention to in Anti-corrosion of Industrial centrifugal Fan

Apr 16, 2019

1.Material selection of industrial centrifugal fan

Selection of industrial centrifugal fan material is important because of different materials and separation, requires the choice of different models. After the machine type and main parameters are determined, according to the corrosion resistance of different materials in different environments, comprehensive physical and chemical properties, cost-performance ratio and many other factors, the strength part materials are determined from the fundamental surface. As far as the material itself is concerned, the target material is safe.


2. Mechanism design of industrial centrifugal fan

A good design can prolong the service life of the equipment and ensure the safety of the equipment. For the structural design, the design defect which is easy to accelerate corrosion is the tendency of stress concentration and the environment of crevice. Sometimes, although the corrosion rate is small in the immersion solution of metal, the corrosion rate is very small. However, the formation of crevice will cause serious crevice corrosion due to the change of chemical and electrochemical state of internal solution.


3. Surface Protection measures of Industrial centrifuge

One of the basic ideas to control corrosion is to isolate the corrosion environment. In the design of industrial centrifugal fan, surface treatment methods, such as flanges, zinc plating, chromium plating and chemical plating, are often used. These methods are effective in many environments, but an important phenomenon must be paid attention to for rotating parts. The matrix material and the coating are two kinds of materials, the coefficient of linear expansion is different, the deformation amount will be different in the elastic deformation of the rotating parts, resulting in a large number of micro-cracks, and if the above-mentioned phenomenon exists, the corrosion will be accelerated. Therefore, the surface protection method of rotating parts should be carefully adopted.


We should consciously maintain the industrial centrifugal fan on daily work, clean the inside dust regularly, add the lubrication oil every month to avoid stuck bearing issue.www.jnblower.com
