MAGNETIC LIQUID SEALING DEVICE ADAPTED TO AXIAL AND RADIAL DISPLACEMENT AT JOINT

WIPO Patent Application WO/2020/006700

A1

A magnetic liquid sealing device (10) that is adapted to the axial and radial displacement at a joint, comprising: an end cover (100); a first clamping plate (200) having a rubber sealing ring, the first clamping plate (200) having the rubber sealing ring being fixed to the end cover (100) by means of a first screw (201) and a second screw (202); a second clamping plate (300) having a rubber sealing ring, the second clamping plate (300) having the rubber sealing ring being mounted into a groove of the end cover (100); a basic sealing structure (400), the basic sealing structure (400) being fixed to the second clamping plate (300) having the rubber sealing ring by means of a third screw (401) and a fourth screw (402) so as to be isolated from the end cover (100) by means of the first clamping plate (200) having the rubber sealing ring and the second clamping plate (300) having the rubber sealing ring. The present device isolates a connected component from a magnetic liquid sealing structure by means of two clamping plates, so that the axial and radial deformation and displacement of the connected component will not be loaded onto parts in the magnetic liquid basic sealing structure, and the service life of magnetic liquid sealing may be prolonged.
