Title (EN) LOW-TEMPERATURE FLUID PUMP AND LOW-TEMPERATURE FLUID TRANSFER DEVICE
(FR) POMPE À FLUIDE À BASSE TEMPÉRATURE ET DISPOSITIF DE TRANSFERT DE FLUIDE À BASSE TEMPÉRATURE
(JA) 低温流体用ポンプおよび低温流体移送装置
Abstract:
(EN) Provided are a low-temperature fluid pump and a low-temperature fluid transfer device with which vaporization of the low-temperature fluid can be reduced. The low-temperature fluid pump is equipped with an impeller, a rotary shaft (9), a case, and a magnetic bearing (11). The rotary shaft (9) is connected to the impeller. The rotary shaft (9) is held inside the case. The magnetic bearing (11) supports the rotary shaft (9) so as to be capable of rotating with respect to the case. The magnetic bearing (11) includes a yoke and one or more coils (11b). The yoke constitutes at least a part of a magnetic circuit (11e). The one or more coils (11b) surround a portion of the yoke. The yoke includes one or more permanent magnets (11c) arranged at a position constituting a portion of the magnetic circuit (11e).
(FR) L'invention concerne une pompe à fluide à basse température et un dispositif de transfert de fluide à basse température avec lesquels il est possible de réduire la vaporisation du fluide à basse température. La pompe à fluide à basse température est équipée d'une roue-hélice, d'un arbre rotatif (9), d'un corps de pompe et d'un palier magnétique (11). L'arbre rotatif (9) est relié à la roue-hélice. L'arbre rotatif (9) est contenu dans le corps de pompe. Le palier magnétique (11) supporte l'arbre rotatif (9) de manière à pouvoir tourner par rapport au corps de pompe. Le palier magnétique (11) comprend une culasse et au moins une bobine (11b). La culasse constitue au moins une partie d'un circuit magnétique (11e). L'au moins une bobine (11b) entoure une partie de la culasse. La culasse comprend au moins un aimant permanent (11c) disposé au niveau d'une position constituant une partie du circuit magnétique (11e).
(JA) 低温流体の気化を抑制することが可能な低温流体用ポンプおよび低温流体移送装置を提供する。低温流体用ポンプは、インペラと、回転軸(9)と、筐体と、磁気軸受(11)とを備える。回転軸(9)はインペラに接続される。筐体は、回転軸(9)を内部に保持する。磁気軸受(11)は、回転軸(9)を筐体に対して回転可能に支持する。磁気軸受(11)は、ヨークと少なくとも1つのコイル(11b)とを含む。ヨークは磁気回路(11e)の少なくとも一部を構成する。少なくとも1つのコイル(11b)はヨークの一部を囲む。ヨークは、磁気回路(11e)の一部を構成する位置に配置された少なくとも1つの永久磁石(11c)を含む。
