In a temperature environment exceeding 250°, the strength of most materials will drop significantly. However, in the face of special process requirements in cement plants, steel plants, aluminum plants, chemical plants, etc., fans need to work in high temperature environments above 300°. This requires high-temperature centrifugal fans to have good heat resistance and high temperature resistance.
The high-temperature fan uses advanced R&D software for finite element analysis and flow channel optimization design; in terms of material selection, full consideration is given to the creep strength, durable strength and durable plasticity of the material; in terms of thermal expansion design, full consideration is given to the thermal expansion of the casing and shaft seal. The thermal expansion, the clearance fit between the air inlet and the impeller, the fit tolerance between the impeller and the main shaft, and the linear expansion of the main shaft; in terms of heat dissipation, fully consider the heat dissipation of the bearings and the heat dissipation of the shaft seal; for the shutdown of large F-type high-temperature fans, consider a slow-turn device design.
High temperature fan features
1. 310S/304 material/316L material.
2. The impeller is resistant to high temperatures.
3. The impeller is made based on stainless steel 310s.
4. The fan impeller is cooled by water at the transmission connection part to prevent the motor from burning out.
5. The fan is insulated. The outer layer of the casing passes through two layers of casing, and insulation cotton is added in the middle to prevent heat loss.
6. Impeller blades, curved front disc and flat rear disc. The material is made of 310s stainless steel with high strength and durability. The blades are made of stainless steel to resist high temperatures. And it has undergone strict dynamic and static balance correction. Good air performance, high efficiency and smooth operation.
