Abstract
The present disclosure discloses a magnetic liquid sealing device adapted to axial and radial displacements of connection, which includes: an end cover; a rubber-sealing-ring equipped first clamping plate fixed on the end cover by a first screw and a second screw; a rubber-sealing-ring equipped second clamping plate installed in a groove of the end cover; a fundamental sealing structure fixed on the rubber-sealing-ring equipped second clamping plate by a third screw and a fourth screw, so as to be isolated from the end cover by the rubber-sealing-ring equipped first clamping plate and the rubber-sealing-ring equipped second clamping plate. The device isolates the connected component from the magnetic liquid sealing structure by the two clamping plates, such that the axial and radial deformations and displacements of the connected component will not be loaded on parts in magnetic liquid sealing structure, prolonging the service life of the magnetic liquid sealing.
