Problems solved by technology

[0008] However, in the prior art, since the buffer 600 is installed in the supply channel K1 connecting the liquid supply system 500 and the cooled device 300, not only extra space is required, but also heat exchange occurs in the buffer 600, resulting in Decreased cooling efficiency

Embodiment 1）

[0081] refer to figure 1 , the liquid supply system of Embodiment 1 of the present invention will be described.

[0082]

[0083] refer to figure 1 , the overall structure and usage method of the liquid supply system 100 according to Embodiment 1 of the present invention will be described. In the liquid supply system 100 of the first embodiment, the ultra-low temperature liquid L is supplied to the device to be cooled 300 having the superconducting coil 320 inside the resin container 310 as in the prior art. Take this as an example. As a specific example of the cryogenic liquid L, liquid nitrogen or liquid helium can be used.

[0084] The liquid supply system 100 includes a first container 110 containing a cryogenic liquid L, a second container 120 arranged in the liquid L contained in the first container 110 , and a bellows 130 inserted in the second container 120 . Inside the second container 120, the outer area of ​​the bellows 130 constitutes the first pump chamber...

Embodiment 2）

[0098] figure 2 Example 2 of the present invention is shown. In this embodiment, the description will be given for the case where a small bellows is provided below the bellows. Since other structures and functions are the same as those in Embodiment 1, the same components are assigned the same reference numerals, and their descriptions are omitted.

[0099] In this embodiment, the bottom side of the second container 120 and the bellows 130 are connected by a small bellows 125 having a smaller outer diameter than the bellows 130 . The small bellows 125 communicates with the inside of the first container 110 and expands and contracts as the shaft 150 reciprocates.

[0100] When the configuration shown in the above-mentioned first embodiment is employed, the pumping volume (discharge volume) of the first pump chamber P1 is greater than the pumping volume of the second pump chamber P2. In order to further reduce pressure fluctuations (pulsation), the difference in the above pu...

Embodiment 3）

[0106] image 3 Example 3 of the present invention is shown. In this embodiment, a case where a structure for suppressing axial misalignment is provided below the bellows will be described. Since other structures and functions are the same as those in Embodiment 1, the same components are assigned the same reference numerals, and their descriptions are omitted.

[0107] In this embodiment, a shaft member 181 is provided at the lower end of the bellows 130 , and a bearing 182 of the shaft member 181 is provided at the bottom of the second container 120 . The bearing 182 is an annular member, and a bearing member 182a is provided on the inner peripheral portion of the front end. The other structures are the same as in Embodiment 1, so the description thereof is omitted. As for the bearing 182 , it is preferable to provide a through hole on its side surface, so that the liquid L can freely come and go between the inner side and the outer side of the bearing 182 . According to...

Abstract

Provided is a liquid supply system with which improved cooling efficiency is achieved while space is saved. This liquid supply system is characterized in that a first pump chamber (P1), formed by the outside of a bellows (130), is formed within a second container (120), and is provided with a first intake port (121), which draws into the first pump chamber (P1) a liquid within a first container (110), and a first delivery port (122), which delivers from the first pump chamber (P1) to a supply passage (K1) the liquid (L) that has been drawn in. In addition, a second pump chamber (P2) is formed within the bellows (130) by means of a sealed space, and is provided with a second intake port (123) which draws into the second pump chamber (P2) the liquid (L) within the first container (110), and a second delivery port (124) which delivers from the second pump chamber (P2) to the supply passage (K1) the liquid that has been drawn in.

Description

technical field [0001] The invention relates to a liquid supply device for supplying ultra-low temperature liquids such as liquid nitrogen and liquid helium. Background technique [0002] Conventionally, in order to maintain a superconducting coil or the like at a cryogenic temperature, it is known to supply a cryogenic liquid such as liquid nitrogen into a container housing the superconducting coil (refer to Patent Document 1). refer to Figure 7 , the prior art liquid supply device will be described. Figure 7 It is a schematic diagram of the state of use of the liquid supply device in the prior art. [0003] For the device 300 to be cooled including the superconducting coil 320 inside the container 310 made of resin, the conventional liquid supply device 500 continuously supplies the ultra-low temperature liquid into the container 310 in order to maintain the superconducting coil 320 in a superconducting state. L. [0004] The liquid supply device 500 includes a first c...
