摘要： A cryogenic pump for liquefied gases is provided, which shortens precooling time, has a small loss of cryogenic liquefied gas, excels in pump efficiency, and is advantageous in cost. A motor 1 and an impeller 2 are coupled by a shaft 3 for transmitting a rotative drive force therebetween, and the motor 1 is arranged on an upper side and the impeller 2 is arranged on a lower side. The motor 1 and the impeller 2 exist in an enclosed space 14 where they are communicated with each other and into which the cryogenic liquefied gas is introduced. A heat adjusting unit 11 is provided between the motor 1 and the impeller 2, the heat adjusting unit maintaining existence of the impeller 2 in a liquid phase of the cryogenic liquefied gas and maintaining existence of the motor 1 in a gas phase of the cryogenic liquefied gas. Thus the submerging of the motor 1 in the liquid becomes unnecessary, whereby the precooling time can be reduced remarkably and the loss of cryogenic liquefied gas due to vaporization caused by the submerging can be reduced, and in addition, the motor 1 itself can be configured at a comparatively low cost.
摘要翻译：提供了一种用于液化气体的低温泵，其缩短预冷时间，低温液化气体的损失小，泵效率优异，成本有利。马达1和叶轮2通过轴3联接，用于传递其间的旋转驱动力，马达1布置在上侧，叶轮2布置在下侧。电动机1和叶轮2存在于封闭空间14中，它们彼此连通并且引入低温液化气体。在电动机1和叶轮2之间设置有热调节单元11，该热调节单元保持叶轮2在低温液化气体的液相中的存在，并且将电动机1的存在保持在低温液化气相加油站。因此，电动机1在液体中的浸没变得不必要，从而可以显着降低预冷时间，并且可以减少由浸没引起的汽化引起的低温液化气体的损失，另外，马达1本身也可以被配置成本相对较低。
