磁懸浮渦輪鼓風機 Introduction:

Maglev Turbo blower is a new type of centrifugal blower based on magnetic levitation bearing technology. They achieve contactless suspension operation of the rotor through electromagnetic force, completely eliminating mechanical friction. They offer advantages such as high efficiency, 節能, 低噪音, and long service life. Compared with traditional positive displacement Roots blowers, their efficiency can be increased by 30%. They have been widely used in various industries, including backwashing, ash silo gasification, sewage aeration, municipal wastewater treatment, aquaculture oxygenation, desulfurization oxidation, petrochemicals, steel, cement, metallurgy, power generation, and food fermentation, gradually replacing traditional Roots blowers and ordinary centrifugal blowers.

Working Principle of Magnetic Levitation Turbo Blowers:

They primarily rely on magnetic levitation bearing technology and high-speed motor drive. This type of blower is directly driven by a high-speed motor, and the speed is controlled by a frequency converter. The key components include an active magnetic levitation bearing system and controllable electromagnetic force, which work together to achieve contactless, wear-free suspension support of the internal rotating magnetic levitation bearing. The magnetic levitation bearing is directly connected to the impeller, resulting in zero transmission loss, thus achieving successful gas delivery with no internal wear, 低噪音, and no lubrication required.

Shandong Mingtian Group 磁懸浮渦輪鼓風機 Core Technology:

① High-Efficiency Centrifugal Impeller

Designed using three-dimensional flow theory, maximizing impeller efficiency and providing a wide operating range. The centrifugal impeller is made of high-strength forged aluminum, with strong deformation resistance, and is precisely machined by a five-axis CNC machining center. The impeller surface is treated with hafnium oxide anodizing to enhance its corrosion resistance, resulting in less wear during long-term high-speed operation.

② Five-Degree-of-Freedom Magnetic Levitation Bearing

The company holds a patent for 12-level radial magnetic bearing technology. The magnetic levitation bearing uses controllable electromagnetic attraction to stably suspend the rotating shaft. During rotation, the shaft has no mechanical contact or friction, thus achieving high efficiency. There are no speed-increasing gears or oil-lubricated bearings, and no lubricating oil is required, resulting in oil-free air output.

③ Dedicated Control System

Equipped with a high-power variable frequency speed control system with complete independent intellectual property rights, the inverter boasts a measured efficiency (output power/input power) of up to 98%. It regulates motor speed by changing the output current frequency of the inverter, thereby adjusting the flow rate. It offers a wide operating range and automatically adjusts the motor speed according to the pipeline network conditions, enabling precise aeration. 電動機控制系統, magnetic levitation control system, and overall machine control system are integrated into a single unit.

④ High-Power High-Speed ​​Permanent Magnet Synchronous Motor

Utilizing a high-speed, high-power permanent magnet synchronous motor, made of samarium-cobalt magnet steel with a 42CrMoA shaft and H-class insulation, the motor is compact, lightweight, and features high power density and high rotational speed, reaching up to 60,000 RPM. It allows for stepless speed control. The motor rotor and impeller are directly coupled, resulting in low operating failure rate and high transmission efficiency.

⑤ Self-Generating System or UPS Power Supply

In the event of an unexpected power outage, the motor switches to “generation” mode. The rotor continues to rotate at high speed due to inertia, cutting the motor stator windings and converting kinetic energy into electrical energy. Simultaneously, the inverter switches to “rectification mode,” supplying the generated electricity to the “DC bus.” After conversion by the DC-DC converter, it continues to power the control system and magnetic levitation bearing controller until the rotor completely stops rotating and ceases generating electricity, preventing damage to the equipment caused by sudden power failure.
