What is centrifugal suction fan? Application in life and production

Like axial fans , centrifugal exhaust fans are one of the most widely used ventilation fans today. So how is this device structured? How does the principle work? TipsMake.com will help you answer these questions!

What is centrifugal suction fan? Structure and principles of operation

Centrifugal fan is a type of fan that draws air along the axis based on centrifugal force. Depending on the criteria, one can divide centrifugal fan into different types such as:

1. According to the structure: Centrifugal fan has direct motor movement and motor movement indirectly with belt set completely outside.
2. According to flow and pressure: Low pressure centrifugal fan, medium pressure centrifugal fan and high pressure centrifugal fan.

Constructing centrifugal fan

Centrifugal fans are designed with 4 main parts including fan blades, impellers, transmission system and motor.

1. Fan cover: Usually made from rust-free metal coated with electrostatic paint. The task of the fan casing is to simultaneously support the connection between the fan and the installation position. In addition, the fan shell also helps minimize the vibration and noise of the engine during operation.
2. Centrifugal impellers : Balanced dynamically by a digital control system, ensuring the fan runs smoothly and without shaking.
3. Drive system: It is tasked to connect the motor with the propeller tail in the suction door. Belts are usually made of high quality, durable rubber.
4. Motor : Is the part that creates the movement of centrifugal fan.

Principle of centrifugal fan operation

Step 1 : Centrifugal fans work on a very simple principle. Specifically:

Step 2 : When the rotor rotates, the pressure at the center of the fan is small, the air will enter the center of the fan and here they will be energized by centrifugal force.

Step 3 : Roto draws air along the fan shaft, thanks to centrifugal force surrounding the fan casing and pushes the wind towards the fan shaft.

Step 4 : Dust air is pushed into the dust collector.

Step 5 : The reel creates pressure and transfers air into the machine.

Step 6 : Fan casing converges and redirects air flow to the inside.

Step 7 : Propeller centrifugal air flow and push air containing dust, toxic gas out of the fan in the same direction.

Application of centrifugal exhaust fans in life and production

The introduction of centrifugal fan has brought us many benefits, from the fields of life to production and business activities:

1. Used to vacuum dust, heat, chemical vapors in steel boilers and boilers
2. Blowing fresh air for tunnel construction
3. Exhausting exhaust can generate small and fine dust in enamel lines of a brick factory or for grinding, cutting machines, planers
4. Ventilate the basement or where a direct ventilation fan cannot be installed
5. Suction central air conditioning, pressure regulating bridge
6. Air supply for incinerators and boilers
7. Fresh air supply and exhaust gas for restaurants, hotels, .
