The small cyclone ultra-high-speed centrifuge adopts the direct drive structure of high-speed permanent magnet synchronous motor, and integrates the centrifugal impeller and motor drive. It achieves contact-free rotor suspension with high-precision air foil bearings.
The main function of permanent magnet synchronization is to drive the rotation of the rotating shaft. It generates a current with controllable frequency through the inverter, and inputs this current into the motor stator to generate a rotating magnetic field, driving the rotating shaft to rotate at high speed.
The main function of the fan is to realize the air blast, and the impeller that rotates at high speed with the rotating shaft drives the air to enter from the air inlet of the volute, and the air becomes the gas with a certain flow rate and pressure under the guidance and pressurization of the volute, and finally blows out from the air outlet of the volute, so as to realize the air blast of the fan.

(1) Product advantages
1. Vehicle specification level – using hydrogen fuel cell supporting ultra-high-speed air suspension host, it has passed 300,000 start-stop verification, 120,000 rpm maximum speed verification, and durability verification;
The small cyclone model adopts the main head design to represent the key technology research and development level and innovation ability of the ultra-high-speed air suspension blower in the industry, overcoming the disadvantages of double air outlet convection, the reduction of the total efficiency of the whole machine, the main engine performance of the vehicle level, the full dynamic pressure air suspension bearing, and more than 300,000 times of durable start-stop life test, which reduces the failure point to ensure the stable and safe operation of the machine.
1.2 The full range of ultra-high-speed air suspension blower products are more intelligent and stable PLC control system
The control system is purchased from the world’s leading PLC programmable logic controller, which should be scalable, anti-interference and corrosion-resistant. The point-to-point communication rate is efficient, the machine runs more stable, the speed is accurately controlled, the cheap single-chip microcomputer circuit board is eliminated, the single-chip microcomputer signal transmission rate is low, it is not easy to repair, once damaged, it must be replaced as a whole, and the blower increases the maintenance cost of the owner in the later stage of operation, and there is no scalability. Panels are susceptible to air corrosion causing serious failures. And it is easy to be affected by signal interference, resulting in wrong actions, such as internal current interference of the inverter, resulting in sudden shutdown, display data confusion, screen dead pixels, screen no data display, etc.
1.3 100% oil-free design
The use of full dynamic pressure air suspension bearings ensures the high quality of the gas: oil-free, water-free, clean and dry. It not only meets the requirements of high-quality gas consumption at the customer’s site, but also simplifies the post-treatment procedure, while also reducing procurement and maintenance costs.
