The axial flow is the airflow in the same direction as the axis of the fan blade, such as an electric fan, an air conditioner, an external fan, and an axial flow mode.
Also called the local fan axial flow fan is a fan used in industrial and mining enterprises, security is different from its general fan motor and fan blades are in a cylinder shape is in a cylinder shape, for local ventilation, convenient installation, ventilation effect, safety, can be connected with the air duct the wind sent to the designated area.
The main difference between centrifugal fans and axial fans is that:
1. The centrifugal fan changes the flow direction of the medium in the air duct, while the axial fan does not change the flow direction of the medium in the air duct;
2, the former installation is more complex
3, the former motor and fan are generally connected through the shaft, the latter motor generally in the fan;
4, the former is often installed in the air conditioning unit inlet and outlet, boiler drum, fan, and so on. The latter is usually installed in the middle of the air duct or the front end of the air duct.
In addition, there are diagonal fans, the wind pressure coefficient is higher than the axial fan, and the flow coefficient is larger than the centrifugal fan. Fill the gaps between the axial flow fan and centrifugal fan. Meanwhile, the utility model has the characteristics of simple and convenient installation.
