Ordinary type Exhaust fan It can be used for ventilation and ventilation in general factories, warehouses, offices, houses and other places. It can also be used for forced ventilation of air coolers, air coolers, evaporators, condensers, etc. the fan factory introduces anticorrosive and explosion-proof axial fans with anticorrosive materials and explosion-proof measures, and matches explosion-proof motors. It can be used for explosive, volatile and corrosive gases for general purposes. Ventilation and ventilation equipment.

  

Exhaust fan, also called local fan, is a kind of fan commonly used in industrial and mining enterprises. But unlike the general fan, its motor and fan blades are in a cylinder. The shape is a cylinder, which is used for local ventilation, convenient installation, obvious effect of ventilation and air exchange, safety, and can be sent to the designated area by the wind tube.

  

The exhaust fan is mainly composed of impeller, casing, motor and other components, and the bracket is connected with the shell and ventilator. The impeller and housing of the anticorrosive axial fan are made of FRP, and other types of axial fans are usually made of steel plates.

  

When the impeller rotates, the gas enters the impeller axially from the inlet, and is pushed by the blade on the impeller to increase the energy of the gas and then flow into the guide vanes. The guide vane deflects the deflected gas flow into axial flow. At the same time, the gas is introduced into the diffuser tube, which further converts the kinetic energy of the gas into the pressure energy. Finally, the working pipeline is introduced.

  

The above is about Exhaust fan The composition and working principle of the introduction, I hope to help you after reading, if you have other questions you want to consult, you can contact us.
