AII series centrifugal blowers

 When everyone consults the air levitation blower, they also raise a question, that is, what is the difference between a magnetic levitation blower and it? We compared its performance with core technology and came to the following conclusions:

 

1. The first is the difference between the working principles of the two:

 

  The air suspension centrifugal blower is a single-stage high-speed centrifugal blower. It is a brand-new concept blower. It adopts three core high-end technologies: "ultra-high-speed direct-connected motor", "air suspension bearing" and "high-precision single-stage centrifugal impeller". A new area of blowers with high efficiency, high performance, low noise and low energy consumption. It is a new generation of high-tech civilian products developed with great concentration of aviation turbomachinery design experience.

 

  The magnetic levitation blower is a magnetic levitation high-speed permanent magnet motor that directly drives the three-dimensional flow impeller, which generates kinetic energy and pressure potential energy under the drive of the high-speed rotating impeller. Part of the kinetic energy is converted into pressure potential energy in the diffuser and volute flow path to change the flow direction. Finally, enter the pipe network through the exhaust pipe.

2. The product structure of the two is different: the air suspension blower has a simple structure and belongs to the air cooling system, and can operate below 250°C without additional cooling; the latter has a complicated structure, and the motor needs + water cooling + water pump + blower for air cooling.

 3. The difference between the two motors: the former has a simple structure, low heat generation, and long life; the latter has a complex structure, large heat generation, and high failure rate.

4. Comparison of the two bearings: the air suspension bearing (mechanical design system) has a simple structure and high efficiency, which is conducive to maintenance; the electromagnetic induction system (motor system) has a complex structure, low efficiency, and difficult maintenance.

5. Comparison of the two impellers: high material strength, strong wear resistance and corrosion resistance, low wear during long-term high-speed operation, efficiency will not decrease, and stable performance; when high-speed operation, the performance degradation is more obvious as the material wears out. The inlet air filtration requires high precision.
