Anti-corrosion Measures of Heart Fan

May 04, 2020

First, the selection of the material of the fan is important

Because of different materials and separation requirements, we need to choose different models. After the model and main parameters are determined, according to the corrosion resistance of different materials in different environments, the physical and chemical properties, cost performance and many other factors are combined to determine the strength parts materials from the fundamentals. From the material itself, it is aimed at the target material is safe.

Second, the mechanism design of fan

an excellent design can prolong the service life of the equipment and ensure the safety of the equipment. for structural design, the design defects that are easy to accelerate corrosion are stress concentration tendency and crevice environment. sometimes, although the corrosion rate is small in metal immersion solution, cracks are formed, which will cause serious crevice corrosion due to changes in chemical and electrochemical states of internal solution.

Third, surface protection measures for centrifuges

A basic idea to control corrosion is to insulate the corrosion environment. In centrifugal fan design, surface treatment methods are often used, such as flange, galvanizing, chromium plating, chemical coating and so on, these methods are effective in many environments.
