I believe, with all kinds of fans in the country selling, we sometimes do not know which fan has what effect, or what is the difference between two fan, a customer said to reflect the explosion-proof axial flow fan and axial flow fan confused, now Zhejiang prosperous explosion-proof fan Limited by Share Ltd to teach all the difference:

The explosion proof axial flow fan adopts the simplest structure of the fan directly connected by the motor and the impeller, which changes the complex structure of the current coal mine exhaust axial ventilation and all belt drive or long shaft transmission, which is good for operation and maintenance. The roof fan reverses and reverses, and the SF type low noise axial fan manufacturers can achieve 65% to 85% of the positive air volume, so it is not necessary to set up another anti air channel, which has the advantages of saving capital investment and fast wind speed. The axial flow fan is also called the local fan, a fan used in industrial and mining enterprises, security is different from its general fan motor and fan blades are in a cylinder shape is in a cylinder shape, for local ventilation, convenient installation, ventilation effect, SF low noise axial flow fan, safety, can be connected to the air duct lookout refers to the D area.

The above is the difference between them. We hope to help you. You still need to choose according to your needs. Our company specializes in explosion-proof axial flow fans. If there are other questions, please contact us.

Workng principle of axial flow fan

When the impeller rotates, the SF type low noise axial fan is sold, and the gas enters the impeller from the inlet of the inlet axially. It is pushed up by the upper blades of the impeller, and the energy of the gas rises, and then flows into the guide vane. The guide blade deflects the gas flow into the axial flow, and introduces the gas into the diffuser tube, and then converts the gas kinetic energy into the pressure energy, and finally the working pipe is introduced.

The mode of the blade of an axial flow fan is similar to the wing of an aircraft. However, the SF type low noise axial fan plant will lift upward force on the wing and support the weight of the aircraft, while the axial flow fan will fix the position and move the air.

The cross section of an axial flow fan is generally a wing profile. The blade can be fixed in position or revolving around its longitudinal axis. The angle of the blade and the air flow or the spacing of the blade can not be adjusted or adjustable. Changing the angle or spacing of the blade is one of the main advantages of an axial flow fan. The angle of the blade spacing produces a lower flow rate, and the increase of the spacing can produce a higher flow rate.

The advanced axial flow fan can change the blade spacing when the fan is running (this is quite similar to the helicopter rotor), thereby changing the flow accordingly. This is called a VP axial flow fan.
