What should I pay attention to when choosing an axial fan?

In the axial fan selection function chart, when there are more than two types of axial fans to choose from, the one with higher compliance and smaller size should be selected first: the one with larger adjustment range should be compared. , To determine the pros and cons.

Before choosing an axial fan, you should get to know the production and product quality environment of the domestic axial fan, such as the types of axial fans produced, the special purpose of the specification products, the growth and promotion of new products, etc., and you should also fully consider environmental protection. In order to choose the best use of fans.

When selecting an axial fan, you should only suppress the use of parallel or series axial fans. When it cannot be suppressed, an axial flow fan of the same model and function should be selected for joint accidents. When the series connection is adopted, there should be a certain pipeline combination between the first-stage axial flow fan and the second-stage axial flow fan.

For ventilation systems with noise reduction requirements, the first choice should be an axial fan with high compliance and low impeller circumferential velocity, and corresponding noise reduction and vibration reduction steps should be adopted according to the noise and vibration propagation methods generated by the ventilation system. The vibration damping step of the axial flow fan and the motor can usually adopt the vibration damping foundation, such as spring damper or rubber damper.

When selecting a centrifugal axial flow fan, when the motor power is less than or equal to 75KW, it is not necessary to install a valve only for starting. When selecting a centrifugal boiler induced draft fan for discharging high temperature flue gas or atmosphere, a valve for starting should be installed to prevent overload during cold operation.

According to the different physical and chemical properties of the gas conveyed by the axial fan, choose the axial fan for different purposes. Explosion-proof axial flow fans should be selected for transporting blasting and flammable gases; dust exhaust or pulverized coal axial flow fans should be selected for dust exhaust or coal powder transportation; anticorrosive axial flow fans should be selected for transporting corrosive gases; High-temperature axial fans should be selected for accidents or high-temperature gas transportation in high-temperature situations.
