Huali magnetic sealing is a shaft seal device that maintains tight contact between the end surfaces of the friction pair through magnetic force compensation, and combines this with an auxiliary seal to prevent leakage. Magnetic sealing is the most advanced sealing device available today. By creatively utilizing a modular magnetic compensation system and new material sealing technology, easy installation can resolve the sealing problems that have long been difficult to overcome in industrial history. It not only enhances the product performance and benefits for customers, but also boosts their competitiveness in the industry as well as their brand value. It not only meets the **policies** requiring green and environmentally friendly practices for industrial transformation and upgrading, but also complies with the 6S workplace management standards that are essential for modern enterprises. Features of magnetic sealing: (1) It employs advanced magnetic compensation technology and a modular design, ensuring consistent loading on the sealing surfaces. (2) Following the concept of friction pairs, a design with a moving ring and a stationary ring was adopted, ensuring that the seal does not come into contact with the shaft during rotation and thereby extending the service life of the equipment. (3) A friction pair made of high-carbon fiber is used, with a friction coefficient of only 0.02 and extremely high wear resistance. (4) The sealing mechanism was changed from external circular surface sealing by the lip seal to internal end-face sealing via magnetic force, thereby enhancing the reliability of the sealing. After using the product in batches under the same operating conditions, users can easily obtain information on the consistency of the product’s lifespan. (5) The end-face sealing structure not only prevents the loss of lubricating oil but also effectively blocks external debris from entering the bearing chamber. (6) The product features a compact design and is easy to install. When matching the original lip seal position, it hardly alters the existing cavity structure; when used as a replacement for mechanical seals, it reduces the difficulty for customers in machining and assembling the cavity, and the lack of requirement for forced cooling results in more stable overall performance of the equipment. (7) Under special operating conditions, phosphor bronze can be used for the moving ring to reduce the likelihood of sparks being generated by metal components in cases where the equipment gets stuck or moves excessively.
