High temperature centrifugal fan is a circular pipeline centrifugal fan. Its straight in and straight out design greatly facilitates the workload of installing and connecting pipes. The impeller of the fan is designed with an aluminum wing shaped blade, which provides high air volume and high static pressure performance while ensuring low noise levels. The flange of the air inlet and outlet is a standard configuration, and the design of this fan makes it suitable for lifting or floor installation. Its impeller width can be designed to achieve the required air volume and pressure under direct connected constant speed conditions. Avoiding the need for a frequency converter to adjust the speed to achieve the desired parameters in the responsible system, thereby reducing initial investment.

　　

　　High temperature centrifugal fantype

　　

(1) High temperature centrifugal fans can be made into two types: right-handed and left-handed. When viewed from one end of the motor and the impeller rotates clockwise, it is called a right-handed rotating fan, represented by "right"; Rotate counterclockwise and call it a left rotating fan, represented by "left".

　　

(2) The outlet position of the fan is represented by the angle of the air outlet of the casing, and both "left" and "right" can be made into six angles: 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, and 225 degrees.

　　

3. Structural characteristics of high-temperature centrifugal fan

　　

(1) Impeller: There are 12 forward curved blades on the impeller. After the impeller is formed, it undergoes dynamic, static balance, and overspeed tests to ensure smooth, safe, and reliable operation.

　　

(2) Shell: Made of low-alloy steel plate into a snail shaped body.

　　

(3) Air inlet: a convergent streamlined overall structure, bolted to the front cover assembly.

　　

(4) Transmission group: composed of a main shaft, water-cooled bearing box, coupling, etc. The main shaft is made of alloy steel, and the bearing box is an integral water-cooled structure.
