Axial flow fan is also called local fan. It is a kind of fan commonly used by industrial and mining enterprises. An electric fan and fan blades are different from common fans in a cylinder. The shape is a cylinder, used for local ventilation, and easy to install. The air ventilation effect is obvious and safe, and the air receiver can send the air to the designated area. Has a simple structure, stable and reliable, low noise, wide range of function selection. So how is the axial flow fan made up? What are the steps for installing an axial flow fan ? Let's get to know it soon.
[Axial fan component classification]
Axial flow fans are mainly composed of 1-hub; 2-blade; 3-shaft; 4-casing; 5-wind winder; 6-streamline body; 7-rectifier; 8-diffuser. As well as the inlet and impeller. The air intake consists of an air collector and a streamlined body. The impeller consists of a hub 1 and a blade 2. The impeller and the shaft 3 are fixed together to form the rotor of the fan, and the rotor is supported on the bearing.
As the motor drives the fan impeller, there is relative airflow through each blade.
The Changlin Dongfan has made the following classification based on the characteristics of the axial fan:
Classified by materials: steel fans, glass steel fans, plastic fans, PP fans, PVC fans, aluminum fans, stainless steel fans, etc. Classification by use: explosion-proof fans, anti-corrosion fans, explosion-proof anti-corrosion fans and other types.
Classified according to use requirements: pipeline type, wall type, post type, fixed type, rainproof and dustproof type, motor external type, etc.
[Axial Fan Installation Method]
First, the hanging installation For the installation of this type of hanging device, the shock absorber is first connected with the fan. The connection is in the form of bolt connection. We must symmetrically install the shock absorber and distribute it on both sides of the fan's corresponding center of gravity. . Then the blower can be lifted directly and inserted into the corresponding suspension bracket. For the height of the hanging bracket and other factors we need to define the user's own, it should be noted that more than 16 # fan is not recommended in this way.
Second, the lateral wall horizontal installation Side wall horizontal installation of the basic idea there is basically no difference between the installation steps and lying type, the same installation, the only difference is that when installing the bracket must be made into oblique arm support In this case, it is necessary to require that the strength and rigidity of the bracket must be sufficient, and the method is not suitable for a fan with a size of 10 or more.
Third, vertical installation:
For a vertical installation, this operation is basically similar to a floor-mounted installation. In addition, special strengthening of the corresponding foundation strength of the wind turbine is required as well as a strict requirement. The connection between the corresponding fan and the two ends of the pipe must be performed with a flexible joint. This will better protect the fan and also isolate the vibration.
Summary: The above is the collection of axial flow fans and related knowledge that Xiaobian collected for everyone. I hope to be helpful to everyone! I believe that after reading the above article, we have a certain understanding of axial flow fan installation!
