What is the difference between a jet fan and an axial fan?
The guide vanes change the deflected airflow into axial flow and introduce the gas into the diffuser tube, further converting the kinetic energy of the gas into pressure energy, and finally introducing the working line. Axial fan blades are generally adjustable angle, most of the axial fan are equipped with a set of blade hydraulic regulator.
The Based on the principle of impact transmission, the high-speed airflow transfers energy to another part of the air in the tunnel, causing it to flow backwards, pushing the air in the tunnel toward the outlet and sucking fresh air from the inlet. When the airflow velocity decays to a certain value, the next group of fans in the same way continue to drive air flow, to achieve the purpose of excluding air pollution in the tunnel.
Jet fans are usually suspended at the top of the tunnel or installed on the side walls of the tunnel, the tunnel itself as a duct, the fan work, from a given energy, resulting in a higher thrust. A part of the air in the tunnel is sucked by the fan, after the work done by the impeller, the high-speed jet from the fan outlet
When the fan is running, through the blade hydraulic adjustment device, can adjust the blade installation angle, and maintain a certain angle, so that it works in the variable conditions still have a high efficiency.
Axial fan When the impeller rotates, the gas enters the impeller from the air inlet in the axial direction, and the energy of the gas is raised by the pushing of the blades on the impeller and then flows into the guide vane
