Abstract
A free liquid helium volatilization superconductive magnetic suspension device includes a low temperature container, a refrigeration, a cold screen, a liquid helium container, a superconductive rotor, a suspension coil, a rotor chamber, a liquid tube, a condenser and a pole-axis displacement sensor. The heat generated by the wires of the suspension coil can be prevented transferring to the liquid helium container by the room temperature current lead joint, the high temperature superconducting current lead joint and low temperature superconducting current lead joint. Therefore the volatilization of the liquid helium in the liquid helium container can be reduced. The status of free liquid helium volatilization in the liquid helium container can be reached through refrigeration cooling condenser to liquefy the helium. The device needs not to be input the liquid helium time after time and can run independently for a long term.
