Ordinary axial fan can be used for general factories, warehouses, offices, homes and other places within the ventilation, can also be used chillers (air cooler), an evaporator, a condenser, a spray-down, etc., are mine shaft flow fan,
Corrosion, explosion-proof axial fan using corrosion-proof materials and measures, and explosion-proof motor matching can be used to transport explosive, volatile, corrosive gases,
Gas delivery requirements axial fan should be no significant dust, non-sticky and fibrous substances; motor directly coupled to a temperature not exceeding 40 ℃, the belt drive type temperature does not exceed 60 ℃. The amount of conveying gas dust shall not exceed 150mg / m3,
Axial fan is mainly composed of the impeller, chassis, motor and other component parts, and the stent using steel casing duct connection. Wherein the anti-corrosion axial fan impeller, casing are made of glass and steel, other types of axial fans generally use steel.
Folding works
Energy when the impeller rotates, the gas from the air inlet axially into the impeller by the impeller blades push leaving the gas rises, and then flows into the vanes. Vanes will deflect the air flow into axial flow, while gas is introduced into the diffuser tube, further gas kinetic energy is converted to pressure energy, and finally to introduce the work of the pipeline.
Work axial fan blades and aircraft wings similar. However, the latter is to lift up the role on the wing and supports the weight of the aircraft, while the axial fan is fixed to the position and movement of air.
Cross-sectional axial fan generally airfoil. Blade position can be fixed, to be rotated about its longitudinal axis. Or blade pitch angle of the blades and airflow can be adjustable or non-adjustable. Changing the blade angle or pitch is one of the main advantages of axial fans. Small blade pitch angles produce lower flows while increasing the pitch may result in higher traffic.
Advanced axial fan blade pitch can be changed (which is quite similar to a helicopter rotor) during fan operation, thus changing the flow accordingly. This is called variable pitch (VP) axial fans.
Folding use
Axial fans called local fans, industrial and mining enterprises is commonly used as a fan, but it is different from the general fan motor and fan blade in a cylinder, the shape is a cylindrical shape, for local ventilation, easy installation, ventilation effect is obvious, safe, hairdryer lookout can be connected to the designated area.
