DYNAMIC SEALING APPARATUS AND DYNAMIC SEALING SYSTEM THEREWITH

摘要

The present invention provides a dynamic sealing apparatus for sealing two relative move devices, the dynamic sealing apparatus includes a ripple pipe, a first conjunction and a second conjunction respectively arranged opposite ends of the ripple pipe and a compensated arm connected between the first conjunction and the second conjunction, the second conjunction is fixed with a first device, a second device is inserted in the ripple pipe through the first conjunction, and the compensated arm allows the first conjunction and the second conjunction to move relative in radical direction. The dynamic sealing apparatus includes the ripple pipe which can bend deformation, the first conjunction and the second conjunction can move relative in the radial direction, so as to compensate a radial offset efficiently between the dynamic device and the static device and to improve the sealing performance.
