Important measures for corrosion Prevention of centrifugal Fan

Oct 25, 2018

In industrial use, the problem of centrifugal fan corrosion has always been a headache. In order to prevent or slow down the corrosion of centrifugal fan, the first choice of material is very important, because of different materials and separation requirements. Different models are needed. According to the corrosion resistance of different materials in different environments, the mechanical and chemical properties and the ratio of performance to price are synthesised to determine the strength part materials from the basic plane after the model and main parameters are determined.


From the point of view of the material itself, it is aimed at the target material is safe. At present, the main anticorrosive centrifugal fan materials are stainless steel, FRP and so on. Secondly, a suitable design for centrifugal fan can prolong the service life of the equipment and ensure the safety of the equipment, and the most basic requirement is that the seal of the anticorrosive centrifugal fan must be handled well.


In addition, the centrifugal fan has to be treated with surface protection, often by means of flange, galvanizing, chrome plating, chemical coating, etc. These methods are effective in many environments, but for rotating parts, It is necessary to pay attention to an important phenomenon that substrate and coating are two kinds of materials, and their linear expansion coefficient is different. Therefore, the method of surface protection for rotating parts should be used carefully.http://www.jnblower.com/
