What are the methods for preventing wear inside the fan volute?
It would be best to describe the specific situation at the scene. Such faults usually do not occur.
Dust in the flue gases from steel mills and power plants, being particulate matter, can cause erosion of the volutes and blades.
To prevent wear, it is necessary to control the dimensional errors in the impeller’s manufacturing, regulate the rotor’s displacement and radial movement, maintain stability in the manufacturing process, and ensure that the inspection methods are effective.
