1. High temperature fans are mainly composed of impellers, casings, air inlets, motors, connectors, cooling blades, and other parts.
2. The impeller adopts a multi blade single inlet centrifugal impeller, made of high-quality galvanized or cold-rolled steel plate, and the blades are designed based on aerodynamic principles. The impeller consists of 10 aft tilting airfoil blades, a curved front plate, and a flat rear plate. The material is made of high-quality steel plates with high strength and durability, and undergoes strict dynamic and static balance correction. Good air performance, high efficiency, and smooth operation.
3. The air inlet adopts a convergent streamlined vortex reduction form, which reduces airflow loss and improves the working efficiency of the high-temperature fan.
4. The casing of the high-temperature fan is connected to the motor through a metal casting installation. The motor shaft head is equipped with a cooling fan blade, and the outer wall of the metal casting is provided with inlet and outlet pipe interfaces to cool the metal casting and shaft head, ensuring the normal operation of the motor at high temperatures.
5. The motor adopts a special high-temperature motor, and the fluid part of the high-temperature fan is made of heat-resistant materials, with reliable cooling structure performance. Compared to other boiler induced draft fans, it has the advantages of simple structure, easy maintenance, and high cost-effectiveness.
