Improvements to sliding field electromagnetic pumps
Description
This invention concerns electromagnetic pumps which can set a conducting liquid into motion, generally a molten metal, through the interaction of a sliding magnetic field and currents induced by this field in a fluid stream. It has a particularly attractive use in nuclear installations comprising a system through which liquid sodium flows. Its aim is the construction of an electromagnetic pump meeting practical requirements in a better manner than those previously known, notably in that it has reduced electromagnetic leaks, hence greater efficiency, and can be built to enable the inductor assembly to be removed and replaced quickly

La presente invention concerne les pompes electromagnetiques qui permettent de mettre en mouvement un liquide conducteur, generalement un metal fondu, par l'interaction d'un champ magnetique glissant et des courants induits par ce champ dans une veine du liquide. Elle trouve une application particulierement interessante dans les installations nucleaires comportant un circuit parcouru par du sodium fondu. Elle a pour but la realisation d'une pompe electromagnetique repondant mieux que celles anterieurement connues aux exigences de la pratique, notamment en ce qu'elle presente des fuites electromagnetiques reduites, d'ou un meilleur rendement, et peut etre realisee de facon a autoriser un enlevement et un remplacement rapide de l'ensemble de l'inducteurAdditional details
