Problems solved by technology

[0003] The magnetic fluid sealing device includes left and right pole shoes and a permanent magnet between them. The pole shoes are slotted to form pole teeth, and the magnetic fluid is adsorbed on the pole teeth to form a seal. The device is used for a long time After being affected by external factors such as magnetic weakening, the magnetic fluid is prone to leakage, which will lead to the failure of the sealing device and affect the service life of the device.

Abstract

The invention discloses a quick-inserting type magnetofluid dynamic sealing ring which comprises an inner ring, a sealing ring, a sealing ring and an outer ring. The outer ring is matched with the inner ring to form a containing cavity used for containing the magnetic fluid; the limiting rings are arranged at two ends of the inner ring for positioning the outer ring; the pressurizing piece rotates along with the inner ring to form high-pressure areas at the two ends of the containing cavity; magnetic fluid leakage can be avoided, and the service life of the sealing device is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering seals, in particular to a quick-pluggable magnetic fluid dynamic seal ring. Background technique [0002] Magnetic fluid seal is a new type of non-contact seal, which utilizes the characteristics of magnetic fluid with both fluidity and magnetic field responsiveness. By forming a magnetic field gradient in the sealing gap, the magnetic fluid can be sealed under the combined action of pressure and magnetic field force. A number of "O-shaped" liquid sealing rings are formed in the gap to achieve the effect of sealing and pressure resistance, and have the advantages of "zero leakage", long life and high reliability. [0003] The magnetic fluid sealing device includes two pole pieces, left and right, and a permanent magnet arranged between them. The pole pieces are slotted to form pole teeth, and the magnetic fluid is adsorbed on the pole teeth to form a seal. The device is used for a l...
