PUMP DEVICE FOR LOW-TEMPERATURE FLUID CIRCULATION, AND LOW-TEMPERATURE FLUID CIRCULATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a pump device for low-temperature fluid circulation and a low-temperature fluid circulation device, capable of suppressing heat conduction from a pressure wall of a low-temperature fluid container to a housing for storing an impeller, compared to a conventional pump for low-temperature liquefied gas.;SOLUTION: A pump device for low-temperature fluid circulation includes an impeller 8, driving parts 9, 10, 11, 12, and housings 6, 7 separate from a wall part of a container 2. The housings 6, 7 have a first housing part 6 storing the impeller 8 therein and arranged in the container 2, and a second housing part 7 connected to the first housing part 6, storing the driving parts therein and arranged outside the container 2. The pump device further includes at least one first connection member 13 connecting between the second housing part 7 and the wall part of the container 2.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
