Abstract

A super-conduction magnetic levitation device without liquid helium volatilization comprises a low temperature container (1), a refrigerating machine (2), a refrigerated screen (3), a liquid helium container (4), a super-conduction rotor (5), a levitation coil (6), a rotor cavity (7), an infusion tube (8), a condenser (12) and a polar axis displacement sensor (13). Heat generated by a current lead wire of the levitation coil (6) after the levitation coil (6) is powered on cannot be transmitted into the liquid helium container (4) through a room temperature current lead wire connector (9), a high temperature super-conduction current lead wire connector (10) and a low temperature super-conduction current lead wire connector (11), so that volatilization of liquid helium in the liquid helium container (4) is reduced. Helium in the condenser (12) is refrigerated through the refrigerating machine (2) to be liquefied so that zero volatilization of liquid helium in the liquid helium container (4) is achieved. The super-conduction magnetic levitation device without liquid helium volatilization does not need to be infused with liquid helium for many times and can independently run for a long period.

Description

technical field [0001] The invention relates to a superconducting magnetic levitation device. Background technique [0002] The continuous development of superconducting materials and low-temperature technology has made superconducting technology more and more widely used in various fields. It continues to meet the needs of my country's industrial modernization and greatly improves the performance and accuracy of various equipment. Cryogenic devices are necessary for realizing superconducting low-temperature environments. The design and performance of cryogenic devices are the basis for the research and development of superconducting instruments and equipment, and are of great significance. The development of refrigerators and conduction cooling technology has provided more choices for the design structure and application occasions of cryogenic devices. At present, the temperature of the secondary cold head of refrigerators can reach below 4K. The superconducting temperatur...
