What form does the axial fan have

　　What form does the axial fan have? What are the characteristics?

　　Axial fans are very useful in many fields such as mining, medicine, food, sanitation, etc. In order to meet the needs of various fields, there are many forms of axial fans in production. So, what are the common forms of axial fans? What are the characteristics of each of these forms?

　　1. Single-stage impeller stage

　　In this form of axial flow fan, both the pressure and frequency are particularly low, which leads to the lower safety of this form of axial flow fan, but it is more convenient to manufacture due to its simple structure.

　　2. Front deflector plus impeller stage

　　This type of axial flow fan is equipped with an adjustable deflector in front of the blades, which can increase the relative speed of the impeller, but at the same time it will reduce the operating efficiency and increase the noise.

　　The above are the two more common forms of axial flow fans, as well as the problems and directions that need to be paid attention to during the use and manufacturing of these two forms.
