The air flow into the impeller through the air intake,. The impeller be pushed by air pressure, to cause the air pressure increase and be transfer into guide blade. The guide blade will change the deflection flow to axial flow. And then push the air-flow into the diffuser, furthermore, the air-flow energy can be converted to pressure energy, at last, this energy can be transfer to blast pipe of requirement.
The running method of impeller of axial-flow fan is same as the wing of plane. But there is different of them. For the wing of plane, the rose force of rotated impeller will bearing the weight of plane and lift up them. But the impeller of axial-flow fan is fixed and it can move the air to flow.
The axial-flow fan is always used in the industrial and mining enterprise. But it is different from others, its rotator and blade is installed inside barrel. It is used to ventilate air and easy to install. It is convenience to use. The effective of air changing is obvious and can directly send the air flow to the place of requirement.
