Publish Time: 2025-02-07
As a high-performance micro liquid delivery device, the micro magnetic pump has been widely used in many fields due to its unique leak-free design.1. The core of magnetic drive technologyThe core of the micro magnetic pump lies in magnetic drive technology. This technology abandons the traditional mechanical sealing method and realizes contactless transmission of torque between the pump shaft and the motor through magnetic coupling. Specifically, the magnetic pump is mainly composed of three parts: the pump body, the magnetic transmission and the motor. The magnetic transmission is a key component, which includes an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve.When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, driving the inner magnetic rotor connected to the impeller to rotate synchronously. In this process, since the pump shaft and the inner magnetic rotor are completely enclosed by the pump body and the isolation sleeve, fully sealed and leak-free liquid delivery is achieved. This design not only avoids the leakage problem caused by the dynamic sealing structure of the traditional pump, but also significantly improves the service life and reliability of the pump.2. Advantages of leak-free designEnvironmental protection: The leak-free design of the micro magnetic pump greatly reduces the risk of environmental pollution caused by harmful liquids. In the chemical, pharmaceutical and other industries, many media are corrosive, toxic or flammable and explosive. Once leaked, they will pose a serious threat to the environment and personnel safety. The leak-free characteristics of the micro magnetic pump ensure the safety of these media during transportation.Improve safety: When handling flammable, explosive or toxic media, the leak-free pump significantly improves the safety of the production process. It avoids accidents such as fire, explosion or poisoning caused by leakage, and ensures the life safety of production personnel and the stable operation of the enterprise.Reduce maintenance costs: Traditional pumps require frequent replacement of seals due to the wear of the dynamic seal structure, which not only increases maintenance costs, but also affects the continuity of production. The leak-free design of the micro magnetic pump reduces the maintenance work caused by leakage, reduces maintenance costs, and improves the operating efficiency of the equipment.3. Application of high-performance magnetic materialsModern micro magnetic pumps generally use high-performance rare earth permanent magnet materials, such as neodymium iron boron. These materials have strong magnetic force, which enables efficient power transmission even in a very small space. At the same time, they also have good stability and corrosion resistance, and can maintain stable performance in harsh working environments.In summary, the micro magnetic pump achieves leak-free liquid delivery through magnetic drive technology. This technology not only improves the service life and reliability of the pump, but also reduces maintenance costs and environmental risks. With the continuous advancement of technology and the expansion of application fields, the micro magnetic pump will play a more important role in the future.
