什么是磁流体What is magnetic fluid

磁流体(Magnetic Fluid)又称磁性液体(Magnetic Liquid)或铁磁流体(Ferromagnetic Fluid), 顾名思义, 它是一种液态状的磁性材料, 该材料既有固体的磁性又具有液体的流动性, 从形态上说它是一种固液两相的胶体混合物, 这种材料即使在重力、离心力或电磁力作用下也不会发生固液分离交替传译。Magnetic fluid is also referred to as “Magnetic Liquid” or “Ferromagnetic Fluid”, just as its name implies, it is a liquid state magnetic material, which features both magnetism of solid and fluidity of liquid, in term of morphology, it is a colloid admixture of two phases of solid and liquid, and is free from solid-liquid separation even under action of gravity, centrifugal force or electromagnet force.

这是一种应用领域十分广阔的纳米级的功能材料。This is a functional material of nanometer grade of wide application fields.

磁流体密封技术Magnetic fluid sealing technology

磁流体密封技术是利用磁流体形态的无定形性和它对磁场的响应特性将其应用于旋转轴动密封的一种全新的密封技术。Magnetic fluid sealing technology is a brand new sealing technology for rotating shaft dynamic seal by using amorphism of magnetic fluid and its response characteristics to magnetic field.

磁流体密封传动装置是由永磁体、转轴、磁极和磁流体组成。当磁流体注入到由永磁体、转轴和磁流体所构成的回路中时, 由于磁场力作用, 在密封间隙内形成稳定的“O”型液体密封环, 并将密封间隙充满而实现密封的目的北京日语翻译。Magnetic fluid sealed driving unit consists of permanent magnet, rotating shaft, magnetic pole and magnetic fluid. When magnetic fluid is injected into the circuit constituted by permanent magnet, rotating shaft and magnetic fluid, due to the action of magnetic field force, stable O-shape liquid sealing ring is formed in seal clearance, and seal clearance is filled fully so as to realize sealing purpose.
