After the high-temperature centrifugal fan is connected to the power supply, the fan rotates. Because the impeller has a groove design, it will drive the air to flow, so the air enters the pump body through the air inlet, and the air is agitated inside. Each groove undergoes a vortex-type pressurization, A cycle of pressurization to form a strong airflow energy, which is discharged from the pump body through the air outlet for use.

Structure

1. The high temperature centrifugal fan is mainly composed of impeller, casing, air inlet, motor, connector, heat dissipation fan blade and so on.

2. The impeller adopts multi-blade single-feed centrifugal impeller, made of galvanized sheet or cold-rolled steel sheet, and the blades are designed according to the aerodynamic principle. The impeller consists of 10 backward inclined airfoil blades, a curved front disc and a flat rear disc. The material is made of steel plate with high strength and good durability, and is corrected by strict dynamic and static balance. Good air performance, high efficiency and stable operation.

3. The air inlet adopts the form of convergent streamlined vortex reduction, the airflow loss is small, and the working efficiency of the high temperature centrifugal fan is high.

4. The casing of the high-temperature centrifugal fan and the motor are installed and connected with metal castings. Heat dissipation blades are installed on the shaft head of the motor. The outer wall of the metal casting is provided with water inlet and outlet pipe interfaces to cool the metal casting and the shaft head to ensure that the motor is at high temperature. Normal operation.

5. The motor adopts special high-temperature motor, and the fluid part of the high-temperature centrifugal fan adopts temperature-resistant materials, and the cooling structure has reliable performance. Compared with other boiler induced draft fan, it has the advantages of simple structure, convenient maintenance and high cost performance.
