Embodiment 1

[0066] refer to figure 1 A liquid supply system according to an embodiment of the present invention will be described. figure 1 It is a schematic structural diagram of the liquid supply system related to the embodiment of the present invention.

[0067] The liquid supply system 10 is a pump device for cryogenic fluid, and the liquid supply system 10 always supplies liquid into the container 31 in order to maintain the superconducting cable 32 in a superconducting state in the cooled device 30 having the superconducting cable 32 inside the resin container 31. Ultra-low temperature liquid L. Specific examples of the cryogenic liquid L include not only liquid nitrogen or liquid helium but also liquids having a temperature below the liquid temperature of liquid nitrogen or liquid helium.

[0068] The liquid supply system 10 roughly includes: a first container (outer container) 11 , the inside of which is vacuum; and a second container 12 arranged to be surrounded by a vacuum spa...

Abstract

The present invention provides a liquid supply system capable of realizing stable pump operation even when an ultra-low temperature liquid containing slurry is used as a liquid delivery object. The liquid supply system supplies ultra-low temperature liquid containing slurry components through expansion and contraction of the bellows (41, 42), and is characterized in that at least the area of ​​the bellows (41, 42) in contact with the liquid is supplied by the low-temperature embrittlement temperature. The system is coated with a resin below the operating temperature.

Description

technical field [0001] The invention relates to a liquid supply system for supplying ultra-low temperature liquid such as liquid nitrogen or liquid helium. Background technique [0002] Hitherto, a technique of supplying a cryogenic liquid such as liquid nitrogen to a vacuum insulated tube housing a superconducting cable or the like in order to maintain the superconducting cable or the like at a cryogenic temperature has been known. In order to maintain the superconducting cable in the superconducting state of the cooled device equipped with the superconducting cable inside the vacuum insulation tube, the liquid supply (circulation) system of the ultra-low temperature liquid always supplies the ultra-low temperature liquid into the vacuum insulation tube. [0003] So far, many cryogenic liquid circulation systems have been used assuming that only liquid is circulated, and a typical centrifugal pump has been often used as a pump mechanism of the cryogenic liquid circulation s...
