Detailed explanation of the working principle of centrifugal fans

Centrifugal fan is a commonly used ventilation equipment in the industrial field, and its working principle is based on the action of centrifugal force. When the motor drives the blades of the fan to rotate, the blades will apply an outward force to the air, causing it to be thrown out along the direction of the blades. During this process, the air is accelerated and subjected to centrifugal force, thereby flowing outward along the curve of the fan housing.

Specifically, the workflow of a centrifugal fan is as follows:

The motor starts and drives the fan blades to rotate.

The blades apply an outward force to the air, causing it to move in the direction of the blades.

Under the action of centrifugal force, air flows outward along the curve of the fan housing.

During the flow process, the air pressure gradually increases, forming a certain pressure difference.

Finally, high-pressure air is discharged from the fan outlet to complete the ventilation or conveying task.

The advantages of centrifugal fans are their compact structure, high efficiency, low noise, and stable performance. Widely used in ventilation, dust removal, and cooling in industries such as factories, mines, tunnels, and cooling towers. In addition, according to different usage requirements, centrifugal fans can also be designed in various forms, such as forward tilting, backward tilting, straight blade, etc., to meet the ventilation needs under various working conditions.

Understanding the working principle of centrifugal fans can help us better use and maintain the equipment, ensuring its long-term stable operation.
