What Is The Structure Principle And Function Of Axial Flow Fan?

Axial flow fan is a kind of equipment that uses mechanical energy to transport air or gas as working medium. Its structure is mainly composed of motor, rotor, guide vane and shell. The rotor is composed of several bent foot blades, which are fixed on the motor shaft. When the motor is started, the rotor starts to rotate, and the air is sucked in, and moves axially along the foot blades, and then compressed and discharged.
The impeller of axial flow fan is a group of blades arranged along the axis direction. Its working principle is to continuously compress, expand and push the gas along the axis direction through the rotation of the impeller blades, resulting in the effect of air flow and wind pressure. Axial flow fan is mainly composed of motor, impeller, air inlet and outlet, shell and accessories. It has the characteristics of small volume, light weight, simple structure, reliable operation, large air volume, low noise, etc., and is widely used in ventilation, air conditioning, dust removal, air supply, ventilation and other occasions.
Axial flow fans are mainly used in the fields of fluid (usually gas) transmission, ventilation and pressurization. Common applications include the following:
Industrial ventilation: axial flow fans can be used to control the temperature, humidity and airflow speed in the plant, prevent the impact of dust, odor and other pollutants on workers' health, and also can be used for heat dissipation of machinery and equipment.
Building ventilation: axial flow fans can be used for building exhaust and ventilation to keep indoor air fresh and comfortable, and prevent problems such as moisture and water accumulation inside the building.
Agricultural greenhouse: axial flow fan can be used for the ventilation and ventilation of greenhouse, control the temperature and humidity inside the greenhouse, and ensure the growth and development of plants.
Automobile manufacturing: axial flow fans can be used in the air circulation system of automobile production to discharge harmful gases in the workshop.
Aerospace: axial flow fans can be used for aircraft power devices, such as the air flow required during the take-off and landing of aircraft.
In short, axial flow fans have a wide range of functions and can be used in many different fields and industries to meet different needs.
