What are the components of the structure of the air suspension centrifugal blower? Air suspension fans can be seen in many industries, and multi-stage filter air suspension fans are more common in air suspension fans.

Multi-level filter air suspension fan is widely used in a variety of smelter heating furnaces, coal preparation plants, heavy media mining, waste water treatment, chemical plant gas and other transport gas places, can also be used to transport other non-corrosive vapor body, such as iron blast furnace exhaust, waste water treatment hydrolytic acidification pool fan, flue gas, shaft furnace calcination exhaust. So, do you have a grasp of its structure?

The motor rotor of the multi-stage filter air suspension fan is composed of several centrifugal impellers, main shaft bearings, spacer sleeves and balancing disks. Among them, each level of centrifugal impeller is designed according to the new basic theory of air suspension blower. The inlet and outlet are backward, and the leaf installation Angle is selected, so that the flow channel of centrifugal impeller is long and the steady flow area is relatively long. The front disc of the centrifugal impeller has a cone-arc shape of equal compressive strength, which reduces the vortex and friction resistance generated by the air inlet.

In order to facilitate the commercialization of air suspension fans and the selection of main parameters of different models, the diameter of each level of centrifugal impeller is the same; Considering the reliability of the operation of the centrifugal fan and the harm of the radial torque to the service life of the rolling bearing, the design scheme of the high pressure end motor rotor of the centrifugal fan has a balancing plate structure, which improves the operation standard of the rolling bearing of the centrifugal fan and increases the service life of the rolling bearing.

In the bearing end cover and each level of centrifugal impeller before and after the selection of multiple, multi-level forged labyrinth seals, radial labyrinth seals and carbon ring seals in the inlet bellows and the tail of the shell, the air suspension blower has the advantages of sealing characteristics, compact structure, easy to use, fast disassembly and so on.
