Description
Superconducting bearings are used in a number of applications for high speed, low loss suspension. Most of these applications have a warm shaft and require continuous cooling, which leads to additional power consumption.
Therefore, it seems advantageous to use these bearings in systems that are inherently cold. One respective application is a submerged pump for the transfer of liquid helium into mobile dewars. Centrifugal pumps require tight sealing clearances, especially for low viscosity fluids and small sizes. This paper covers the design and qualification of the superconducting YBCO bearings for a laboratory sized liquid helium transfer pump.
