Common type axial fan can be used for ventilation in factories, warehouses, offices, houses and other places. It can also be used for forced ventilation of air cooler, evaporator, etc.. Anti-corrosion, explosion-proof axial flow fan adopts anti-corrosion materials and explosion-proof measures, and matches with explosion-proof motor, can be used as ventilation equipment, used in places with explosive, volatile and corrosive gases. The gas transported by the axial flow fan shall be free from obvious dust, viscosity and fibrous materials; The temperature of motor directly connected type shall not exceed 40°C, and the temperature of belt driven type shall not exceed 60°C.
Axial flow fan is mainly composed of impeller, casing, motor and other components, bracket and casing tuyere are connected by section steel.. Among them, anti-corrosion axial flow fan impeller and casing are made of fiberglass, other types of axial flow fans are generally made of steel plate.
The working principle of axial flow fan: when the impeller turns, the gas enters the impeller from the inlet axial direction, and then increases the energy of the gas through the blade to the impeller, and then flows into the guide vane. The guide vane changes the deflected airflow into axial flow, and at the same time introduces the gas into the pressure tube, further converts the kinetic energy of the gas into pressure energy, and finally introduces the working line. The axial fan blade works like the wing of an airplane. However, the latter ACTS on the lift on the wings and supports the weight of the aircraft, while the axial fan is fixed and moves the air. The transverse belt surface of axial flow fan is generally the outline of airfoil. The blade can be fixed or rotated around its vertical axis.. The Angle between the blade and the airflow or the blade spacing should not be adjustable or adjustable. Changing blade Angle or spacing is one of the main advantages of axial flow fans..
The small blade spacing Angle produces a lower flow rate, while increasing the spacing produces a higher flow rate. Advanced axial fans can change the blade spacing (similar to that of a helicopter rotor) as the fan runs, thereby changing the flow rate accordingly. This is the so-called movable vane adjustable (VP) axial flow fan.. Axial flow fan, also known as local fan, is a commonly used fan in industrial and mining enterprises, but different from the general fan, its motor and blade are in a cylinder, its shape is cylindrical, used for local ventilation, easy to install, ventilation effect is obvious, safe, and can be connected with the air cylinder to send the wind to the designated area
