How does the material of the high temperature fan choose?
According to the use of the fan and the use of different conditions, in the choice of materials should take into account the media corrosion, the temperature of the medium, the amount of gas emissions, explosion-proof and the choice of materials, such as the economic requirements.
The main performance indicators of the substitute materials should meet the main mechanical performance requirements of parts, B-level corrosion of the following materials shall not be applied to the rotating parts, nor shall the application of the rest of the parts on the outer surface
In the manufacturing process is strictly prohibited the use of mezzanine, heavy leather and other defects in the material, the material on the outer surface of the material shall not have obvious scratches, aluminum local scratch depth of not more than 0.3mm,
Under normal circumstances, the impeller, chassis, air inlet material selection of ordinary carbon steel Q235A, the spindle selection of 45 high-quality carbon steel, bearing box due to the complex shape of the commonly used cast iron material HT200, bearing box bracket can be cast iron material, The use of steel (angle steel, channel steel), steel and other welding made.
The fan mainly by the impeller, chassis, air inlet, bearing box, spindle, bearing box bracket and other components
