Comparison of operating power between centrifugal fan and axial fan
Some users friends for centrifugal fan and axial flow fan is fuzzy, do not know how to distinguish these two kinds of equipment. In fact, there is a significant difference in the operating power of the two kinds of fans. Under normal circumstances, the work of centrifugal fans increases with the increase of air volume, while the operating power of axial flow fans decreases with the increase of air volume.
In the process of using the centrifugal fan, all the air valves should be closed and then opened during the initial opening period, mainly to avoid engine burning due to excessive DC. In contrast, in the process of starting the axial fan, the damper needs to be fully opened, and then gradually opened to the required air volume.
Centrifugal fan belongs to a driven fluid equipment, is mainly used for various factory production, tunnel construction and construction of ventilation and dust, etc.. It is also often used as ventilation and ventilation equipment for boilers and light industrial furnaces. Or drying and ventilating stored grain.
In addition, there are many other differences between the two types of fans. For example, the connection between the centrifugal fan and the engine is mainly completed through the shaft connection, and the axial flow fan is installed in its internal. Comparatively speaking, the former design is more simple in structure.
After the use of centrifugal fan equipment, it can adjust the flow direction of the medium in the air duct, while the axial flow fan does not change the flow direction of the medium in the air duct. The so-called axial fan is actually a cyclone with the axial position of the wind blade, such as electric fans, air conditioners outside the mechanical and electrical fan is an axial flow fan. At present, axial flow fans are mainly used in places with higher flow requirements and lower pressure.
