Abstract
Disclosed is a multistage magnetic fluid sealing apparatus for superconducting rotating machines. According to the present invention, the magnetic fluid sealing apparatus, which is provided with a first magnetic fluid chamber and a second magnetic fluid chamber that are arranged in a multi-stage manner so as to contain a magnetic fluid capable of sealing the inner portion of a superconducting rotating machines, is installed on one surface of the superconducting rotating machines. The free magnetic fluid sealing apparatus of the invention configured to have a dual structure enables two to three fluid lines to be installed in the superconducting rotating machines.
