Abstract

Procédé destiné à imposer une distribution déterminée de température dans une pompe au repos qui, lorsqu'elle est en fonctionnement, opère à une température différente de celle de l'ambiance. L'injection de fluide en circulation sous pression et température convenables dans le circuit du fluide de barrage du joint d'arbre pendant que la pompe est au repos garantit la distribution voulue de température. Le complément de fluide, qui consiste par exemple en produit de condensation lorsqu'il s'agit de pompes d'alimentation de centrale, passe dans le circuit interne de la pompe lorsque celle-ci est au repos.
