Main uses of axial flow fan and centrifugal fan
Axial flow fan and centrifugal fan are two different products in the fan category. Their main function is to ventilate the air in the environment.
1. Axial flow fan has a wide range of uses, that is, the air flow in the same direction as the axis of the fan blade, such as electric fan. The fan of the external unit of the air conditioner is an axial flow fan. It is called "axial flow type" because the gas flows parallel to the fan axis. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. The axial flow fan is fixed in position and moves the air. Axial flow fan is mainly composed of fan impeller and casing, with simple structure but high data requirements.
2. Centrifugal fan is a kind of driven fluid machinery, which depends on the input mechanical energy to increase the gas pressure and discharge the gas. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; Ventilation and induced draft of boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household electrical equipment; Drying and selection of grain; Wind tunnel wind source and inflation and propulsion of hovercraft.
With the continuous development of science and technology, people have higher and higher requirements for the use of centrifugal fans. In terms of the current development trend of foreign centrifugal fan technology, it will develop in the direction of increasing centrifugal fan capacity, high efficiency, high-speed miniaturization and low noise. The capacity of large centrifugal fan continues to increase. With the large scale of various industrial devices, the capacity of various centrifugal fans required is also increasing. The large centrifugal fans will increase in the market in the next few years.
