Magnetic fluid: also known as magnetic fluid, magnetic fluid

Magnetic fluid is a new type of functional material that exists in liquid form as a magnetic conductive material. It is a stable liquid formed by uniformly dispersing magnetic solid particles with a diameter of 10 nanometers into a base carrier liquid, which has both liquid fluidity and good magnetic conductivity. According to the different base carriers, they can be divided into ester based, water-based, silicone based, etc.

Magnetic fluid seal

The principle of magnetic fluid sealing:Magnetic fluid sealing technology is achieved by utilizing the excellent response characteristics of magnetic fluids to magnetic fields. When injecting magnetic fluid into the gap of the magnetic circuit composed of high-performance permanent magnets, magnetic shoes with good magnetic conductivity, and a rotating shaft, under the action of the magnetic field, the magnetic fluid forms several liquid "O" rings in the gap, thus playing a sealing role.

Characteristics of Magnetic Fluid

It is widely recognized by countries around the world“Zero leakage”Advanced technology of dynamic sealing

  • Long lifespan

    Liquid "Ο" ring seal, no solid contact wear. The lifespan of the seal depends on the service life of the bearing, which can last up to ten years of safe operation without maintenance during this period

  • Optimal torque transmission

    Magnetic fluid seal belongs to the "liquid-solid" contact seal, with no wear. It does not have the problem of wear and leakage between the sealing element and the solid solid interface of the rotating shaft in traditional seals, with 100% power transmission and no torque loss

  • Zero leakage

    Even with helium mass spectrometer detection, it is difficult to detect at a leakage rate of 1×10¹² Pa·m3·s¹

  • High vacuum degree

    The vacuum degree can maintain 1×10Pa

  • High adaptability

    Can meet various equipment requirements from low speed to high speed, from low pressure to high pressure, from room temperature to high temperature
