The high temperature resistant axial flow fan is based on the principle of converting kinetic energy into potential energy. It uses a high-speed rotating impeller to accelerate the gas, then slows down and changes the flow direction to convert kinetic energy into potential energy. In a single-stage centrifugal fan, the gas enters the impeller from the axial direction. When the gas flows through the impeller, it changes to a radial direction, and then enters the diffuser. The gas changes the direction of movement and increases the cross-sectional area of the pipe to decelerate the airflow. This deceleration effect will kinetic energy. Converted into pressure energy. The increase in pressure occurs first in the impeller, and secondly in the expansion process. In a multi-stage centrifugal fan, a refluxer is used to make the air flow into the next impeller, which produces a higher pressure effect.
When using a high-temperature axial fan, you should first consider the temperature and time characteristics, that is, the national standard rule of 280°C/0.5h; secondly, at ordinary working temperature, it can ensure the effective control of the smoke prevention and exhaust system.
At the same time, it is requested that the high-temperature-resistant axial flow fan can periodically stop the experiment, find out the lack of this aspect, and improve it; pipes with various air circulation requirements are available for installation and use. The characteristics of axial flow fans are high temperature resistance, high efficiency, less space and higher temperature than centrifugal fans.
The high temperature resistant axial flow fan can continuously operate 300℃ high temperature specification for more than one hour, continuous operation 100℃ high temperature specification for more than 20 hours without damage. It has a wide range of applications. Variable speed or multi-speed control can be used according to different requirements of the building.
High temperature resistant axial fans are generally used in construction sites such as public buildings, public garages, and tunnel projects. It can be installed directly with the wall, and the installation is convenient and fast. It can be vertical, translational or lifting, which saves space to a large extent.
