Embodiment Construction

[0091] Next, modes for implementing the present invention will be described in detail based on the embodiments with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the components described in this embodiment do not mean that the scope of the present invention is limited thereto unless otherwise specified.

[0092] (Example)

[0093] refer to figure 1 and figure 2 A liquid supply system according to an embodiment of the present invention will be described. The liquid supply system of this embodiment can be suitably used, for example, to maintain a superconducting device in a cryogenic state. That is, in superconducting devices, it is necessary to constantly cool superconducting coils and the like. Therefore, by constantly supplying ultra-low temperature liquid (liquid nitrogen, liquid helium) to the cooled device including the superconducting coil, the cooled device is constantly cooled. More specifically, by providing...

Abstract

Provided is a liquid supply system with which efficient cooling is made possible. The liquid supply system 10 is provided with: a vessel which has pump chambers P1, P2 provided in the interior thereofand is provided with an inlet opening 131b and delivery opening 131c for fluid, supply passages 131e, 131Xc which supply a liquid flowing in from the inlet opening 131b to the pump chambers P1, P2, and a discharge passage 190 which guides the liquid discharged from the pump chambers P1, P2 to the delivery opening 131c, wherein a heat-resistant layer 500 is formed on wall surfaces 180, 181 of theinner walls within the pump chambers P1, P2 that come into contact with the liquid, said layer being formed from a material PTFE having lower thermal conductivity than the members which constitute thewall surfaces 180, 181.

Description

technical field [0001] The present invention relates to a liquid supply system for supplying liquid. Background technique [0002] A bellows pump having a pump chamber formed of a bellows is known as a liquid supply system for circulating a liquid to a circulation channel (see Patent Document 1). The system has two pump chambers vertically up and down, and the bellows constituting each pump chamber are fixed on the shaft that drives up and down by the actuator, and are linked with the movement of the shaft to expand and contract in the up and down direction. [0003] For heat insulation, the pump device is housed in a vacuum container as a whole, and an actuator is provided above the vacuum container. For heat insulation, it is preferable that a suction pipe for supplying liquid from the outside to the pump device and a discharge pipe for discharging liquid from the pump device to the outside are connected to the pump device at positions as far away from the outside air as ...
