Magnetic levitation blower: The future star of high efficiency and energy conservation Introduction to Magnetic Levitation Blower

The magnetic levitation blower, this high-tech green energy-saving equipment, is based on core technologies such as magnetic levitation bearings, ternary flow impellers, and high-speed permanent magnet synchronous motors, achieving frictionless and lubricated operation. Its start-up process involves suspension first and then rotation, with zero transmission loss and remarkable efficiency. Compared with traditional blowers and air suspension blowers, magnetic levitation blowers not only have higher efficiency and lower noise, but also have an extremely low failure rate, do not require a lubrication system, and are more environmentally friendly. Even in the event of a malfunction of the magnetic levitation bearing, the protective bearing in the system can ensure the safe shutdown of the high-speed rotating rotor and prevent serious damage to the equipment.

Detailed structure explanation

The main components of the magnetic levitation blower include high-efficiency centrifugal impellers, magnetic levitation bearings, permanent magnet synchronous motors and dedicated frequency converters. This type of fan integrates an integrated design concept, with core components such as high-speed motors, frequency converters, magnetic levitation bearings, and microprocessing control panels all achieving a high degree of integration. The core of its technology focuses on the efficient synergy between magnetic levitation bearings and permanent magnet motors.

【 Core Components and Technical Principles 】

Magnetic levitation blowers achieve frictionless and lubricated operation through technologies such as magnetic levitation bearings, ternary flow impellers, and high-speed permanent magnet synchronous motors, featuring high efficiency and environmental friendliness.

【 Impeller and Motor Design 】

The impeller design follows the three-dimensional flow theory and undergoes parameter optimization, aiming to maximize the impeller efficiency while expanding its working range. In terms of material, the impeller is made of high-strength forged aluminum or titanium alloy, significantly enhancing the anti-deformation capacity. Through the precise manufacturing by the CNC machining center, the anti-corrosion performance of the impeller has also been further enhanced. According to the determination of experts from the National Fluid Laboratory, the maximum efficiency at the working point of the impeller can be as high as 85%. The permanent magnets installed on the motor spindle ensure the magnetic stability of the spindle. The coils wound on the stator silicon steel sheets generate oscillating magnetic force during operation, which is synchronized with the rotational speed, thereby achieving efficient operation of the motor. Thanks to the application of magnetic levitation bearings, permanent magnet synchronous motors have the advantages of no mechanical friction, low noise, low vibration and long service life, and their maximum speed can reach 50,000 r/min.

【Magnetic Levitation Bearing Technology】

Magnetic levitation bearings suspend the rotating shaft through precise and controllable electromagnetic suction force, achieving wear-free operation. During the rotation process, the rotating shaft is completely free from the constraints of mechanical resistance, thus ensuring an efficient and wear-free operating state. Furthermore, this technology also eliminates the need for maintenance and the use of lubricating oil, ensuring that the air blown out remains in an absolutely oil-free state.

【 Control System 】

Magnetic levitation blowers are usually equipped with vectorless variable frequency control to regulate the flow rate, and the rotation of the permanent magnet motor is precisely controlled by adjusting the frequency. In addition, this system also features intelligent surge prediction and local control functions, and integrates GPRS technology to achieve remote monitoring and data transmission, providing customers with convenient and timely service experiences.

Working principle

Magnetic levitation operates in coordination with the motor

The magnetic levitation blower is directly driven by a high-speed motor, and the frequency converter is responsible for speed regulation. The core active magnetic levitation bearing system provides non-contact and wear-free suspension support for the internally rotating magnetic levitation bearing through controllable electromagnetic force. This design enables the magnetic levitation bearing to be directly connected to the impeller, resulting in extremely high transmission efficiency. Thus, it achieves outstanding performance in gas transportation, such as high efficiency, no wear, low noise and no need for lubrication.

Gas transportation process

The synchronous permanent magnet motor is responsible for driving the rotation of the rotor shaft. The variable frequency power supply provides it with an alternating current of adjustable frequency. After the current is input into the stator of the motor, it generates a rotating magnetic field, driving the rotating shaft to rotate at an extremely high speed. The air-blowing function of the fan is achieved by the high-speed rotation of the impeller to draw in air, which is then guided and pressurized by the volute. Eventually, the air is blown out from the outlet of the volute in the form of high-speed and high-pressure gas, completing the air-blowing process.

Industry application

Industrial gas transportation

Magnetic levitation blowers are widely used in the industrial field, especially in gas transportation. Its characteristics of high efficiency, energy conservation and environmental protection enable it to play an important role in multiple industry fields. In multiple industries such as cement plants, chemical engineering, and food, its powerful gas conveying capacity enables industrial raw materials, dust, and food materials to be efficiently transported through pneumatic conveying systems.

Sewage treatment

Magnetic levitation blowers can also be used for sewage treatment in municipal and industrial fields. By aerating the sewage tank, it can effectively promote the full contact between the biological active substances in the sewage treatment tank and the pollutants in the sewage, thereby achieving an efficient sewage removal effect.

Aquaculture

In aquaculture, by blowing air into the bottom of the aquaculture pond, the oxygen content inside the pond can be significantly increased, thereby enhancing the survival rate of aquatic products.

Applications in other industries

Air lifting technology has been widely adopted in paper mills, brewing industries, textile industries, dairy processing industries, and thermal power industries, etc., thereby enhancing production efficiency.

Summary of Advantages

High efficiency and energy saving

Adopting self-designed high-efficiency centrifugal impellers, synchronous permanent magnet motor drive and magnetic levitation bearing technology, compared with traditional volumetric Roots blowers, the energy-saving rate is as high as 30%. Compared with the gear-speed-increasing single-stage centrifugal blower, it saves energy by approximately 12%.

Stable and low noise

The application of magnetic levitation bearing systems enables the rotating components to have no contact with the mechanical system at all, thereby eliminating mechanical friction, ensuring the stability of operation, and reducing the overall noise at the same time.

Maintenance-free

By eliminating the complex gear transmission and oily bearing system required by traditional fans, this blower achieves no lubricating oil and no mechanical maintenance, greatly reducing the maintenance cost for users and ensuring the long-term stability of the system.

Convenient installation and maintenance

The magnetic levitation centrifugal blower is compactly designed and lightweight, and can be easily installed without large lifting equipment. Daily maintenance only requires the replacement of the air filter cloth, and the operation is simple and convenient.

Remote monitoring function

The blower is equipped with a remote monitoring system, which can monitor the operating status of the blower in real time, provide wireless remote data transmission and fault query, and bring customers a convenient and timely service experience.
