Title (EN) APPARATUS AND METHOD FOR ENLARGING INNER DIAMETER OF INJECTOR FOR REACTOR
(FR) APPAREIL ET PROCÉDÉ D’AGRANDISSEMENT DE DIAMÈTRE INTERNE D'UN INJECTEUR DESTINÉ À UN RÉACTEUR
Abstract:
(EN) A drill assembly and method is provided for enlarging an injector of a reactor. The drill assembly includes an elongated shaft attached to a piloted drill bit including a pilot portion distal from and extending colinearly with the elongated shaft and a cutting portion proximal the elongated shaft and positioned between the pilot portion and the elongated shaft, wherein the cutting portion includes at least one cutting edge extending radially from a center axis of rotation beyond an outer surface of the pilot portion; and a drive device adapted to rotate the elongated shaft about the axis of rotation. The method includes inserting the pilot portion into an injector; and cutting away a portion of an inner surface of the injector with the cutting portion.
(FR) L'invention concerne un ensemble foret et un procédé d’agrandissement d’un injecteur d'un réacteur. L'ensemble foret comprend un arbre allongé fixé à un trépan pilote comprenant une partie pilote distale par rapport à l'arbre allongé et s'étendant de manière colinéaire à ce dernier et une partie de coupe à proximité de l'arbre allongé et positionnée entre la partie pilote et l'arbre allongé, la partie de coupe comprenant au moins un bord de coupe s'étendant radialement depuis un axe central de rotation au-delà d'une surface externe de la partie pilote ; et un dispositif d'entraînement conçu pour faire tourner l'arbre allongé autour de l'axe de rotation. Le procédé comprend l'insertion de la partie pilote dans un injecteur ; et la découpe d'une partie d'une surface interne de l'injecteur au moyen de la partie de coupe.
