Principle of axial fan and jet fan
The working principle of axial fan is that when the impeller rotates, the gas enters the impeller from the air inlet and is pushed by the vanes on the impeller to increase the energy of the gas and then flow into the guide vanes. The guide vane converts the deflection gas into an axial flow, and at the same time, the gas is introduced into the expansion tube, and the kinetic energy of the gas is further converted into the pressure energy, and finally the working pipeline is introduced. Axial fan blades can generally rotate angle, most of the axial flow fan is equipped with a set of blades hydraulic adjustment device. When the fan is running, the installation angle of the blade can be adjusted by the vane hydraulic regulating device, and the angle of the blade is kept at a certain angle, so that the fan still has high efficiency when the working condition is changed.
