The axial flow fan, also called a local ventilator, is a type of fan commonly used in industrial and mining enterprises. It is different from ordinary fans in that the motor and blades are in a cylinder. The shape is a cylinder and is used for local ventilation. , easy to install, obvious ventilation effect, safe, and can be connected to a hairdryer to send the wind to the designated area. It has the characteristics of simple structure, stability and reliability, low noise and wide range of function selection. So how is the axial flow fan composed? What are the steps to install an axial flow fan? Let’s find out right away.
Classification of axial flow fan components
The axial flow fan mainly consists of 1-hub; 2-blade; 3-shaft; 4-casing; 5-air collector; 6-Streamline body; 7-Rectifier; 8-Diffuser. And consists of air inlet and impeller. The air inlet is composed of an air collector and a streamline body, and the impeller is composed of a hub 1 and a blade 2. The impeller and shaft 3 are fixed together to form the rotor of the ventilator, and the rotor is supported on bearings.
When the motor drives the fan impeller to rotate, there is relative airflow passing through each blade.
Changlin Dongfan makes the following classifications based on the characteristics of axial flow fans:
Classified by material: steel fans, fiberglass fans, plastic fans, PP fans, PVC fans, Aluminum fans, stainless steel fans, etc.
Classified by use: explosion-proof fans, anti-corrosion fans, explosion-proof and anti-corrosion fans, etc.
Classified according to usage requirements: pipeline type, wall type, post type, fixed type, rainproof and dustproof type, external motor type, etc.
Axial flow fan installation method
1. Suspended installation
For the installation of suspended equipment, first connect the shock absorber to the fan , the connection form is bolted connection, we need to install the shock absorbers symmetrically, and distribute them on both sides of the corresponding center of gravity of the fan. The fan can then be lifted directly and inserted into the corresponding suspension bracket. The corresponding height of the suspension bracket and other factors need to be defined by our users themselves. What needs to be paid attention to is 16# 2. Side wall horizontal installation
The basic idea of side wall horizontal installation also includes installation steps and lying on the ground There is basically no difference between the two styles. The installation method is the same. The only difference is that when installing the bracket, it must be made into a support type with an inclined arm. In this case, the strength and rigidity of the bracket must be sufficient. Relatively speaking, Yu 10# 3. Vertical installation:
The operation process of vertical installation is basically the same as that of horizontal installation. In addition, it is necessary to specially strengthen the corresponding foundation strength and stiffness of the wind turbine, and maintain strict requirements. The corresponding connection between the fan and the pipes at both ends must be carried out by using flexible joints. This can better protect the fan and also isolate vibration.
