Any metal will be corroded by external factors. Fans are no exception. Fans will be more or less corroded after being used for a long time. When we encounter fan corrosion, we need to take measures What measures to deal with? Next, I will share with you the factors that prevent fan corrosion.
1. Fan surface protection
A basic idea of corrosion control is to isolate the corrosive environment.In the design of Shandong centrifugal fans,surface treatment methods are often used,such as flanges,galvanizing,chrome plating,chemical plating,etc.These methods are effective in many environments,but for rotating parts,an important phenomenon needs to be paid attention to: The base material and the coating are two materials,and their linear expansion coefficients are different,which will produce different deformations when the rotating parts are elastically deformed, resulting in the generation of a large number of microcracks; if the aforementioned phenomenon exists,it will accelerate the formation of corrosion.Therefore, the surface protection method for rotating parts should be used with caution.
2. Choose the right fan material
Because of different materials and separation requirements,different Shandong centrifugal fan models need to be selected.After the model and main parameters are determined,according to the corrosion resistance of different materials in different environments,considering their physical and chemical properties,cost performance and many other factors,the strength part material is determined fundamentally.From the perspective of the material itself,the target material it targets is safe.
3. Mechanism design of fan
A good design can prolong the service life of the equipment and the safety of the equipment.For the structural design,the design defect that is easy to accelerate corrosion is the stress concentration tendency and the crevice environment.Sometimes although the metal is immersed in the solution,the corrosion rate is small;but the crevice is formed due to The chemical and electrochemical state of the internal solution has changed which will cause severe crevice corrosion.
