The working principle, structural composition, use, and daily maintenance of centrifugal fans produced by Suzhou Yonghecheng Fan Industry Co., Ltd.:
1、 Working principle: The power equipment operates to drive the impeller to rotate, sucking air in from the near air inlet. During the rotation of the blades of a centrifugal fan, dynamic action is exerted on the gas to increase its pressure and speed. Under the action of centrifugal force, the gas is discharged from the exhaust port along the blade channel.
2、 Structural composition of centrifugal fan:
1. Rotation direction
Clockwise rotation: When viewing the fan from the motor end, the impeller rotates clockwise.
Counter rotation: When viewing the fan from the motor end, the impeller rotates counterclockwise.
2. Fan outlet angle and intake box angle
The included angle between the center line of the fan outlet and the horizontal direction is the fan outlet angle.
The included angle between the center line of the fan intake box and the horizontal direction is the angle of the fan intake box.
