5. Improve the Centrifugal Fan Structure by Xianrun Blower

5.1 Optimizing Air Inlet of Centrifugal Fan

Starting from the motion law of gas-solid two-phase flow, analyzing the dust particles movement and wear mechanism, changing the trajectories of particles from the pneumatic perspective, are a effective measures to improve centrifugal fan wear.

Selecting reasonable fan air inlet is to improve the fan inlet condition and dust air flow movement mode, so as to reducing centrifugal wear. Practice has proved that the centrifugal fan will have serious uneven wear when using common cylindrical inlet; when the air inlet is modified to horn type inlet, will improve blade wear.

4.2 Blade surface protection treatment & 4.3 Wear resisting cutting edge by Xianrun Blower

4.2 Blade surface protection treatment

Wear-resisting surfacing alloy process in centrifugal fan blade form a hard and wear resistant protective layer on the blade surface, which can improve the fan blade wear resistance. Actual welding wearing layer thickness and position are decided by blade thickness, wear condition and welding technology.

4.3 Wear resisting cutting edge in centrifugal fan impeller

In general, fan blade head has serious wear, so it is essential to improve the wear resisting performance of the blade head. The sinter cemented carbide anti-wear leading edge composed by cemented carbide is an effective measure.
In order to have a good aerodynamic performance, the appearance of the blade leading edge should be made accurately, and the wear-resistant cutting edge can use diffusion combined with electron beam welding technology.
