Magnetic liquid sealing device adapted to axial and radial displacements of connection

A magnetic liquid sealing device adapted to axial and radial displacements of connection comprising:

• an end cover;
• a rubber-sealing-ring equipped first clamping plate fixed on the end cover by a first screw and a second screw, the rubber-sealing-ring equipped first clamping plate comprising a first rubber sealing ring, the first rubber sealing ring being mounted in a groove of the first clamping plate;
• a rubber-sealing-ring equipped second clamping plate installed in a groove of the end cover, the rubber-sealing-ring equipped second clamping plate comprising a second rubber sealing ring and a third rubber sealing ring, the second rubber sealing ring and the third rubber sealing ring being mounted in a groove of the second clamping plate;
• and
• 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 first rubber-sealing-ring equipped clamping plate and the rubber-sealing-ring equipped second clamping plate.
