Abstract
Graphitic packing removal tools for removal of the seal rings in one piece. he packing removal tool has a cylindrical base ring the same size as the packing ring with a surface finish, perforations, knurling or threads for adhesion to the seal ring. Elongated leg shanks are mounted axially along the circumferential center. A slit or slits permit insertion around shafts. A removal tool follower stabilizes the upper portion of the legs to allow a spanner wrench to be used for insertion and removal.
Claims11
A graphitic packing seal ring removal tool comprising:
- (a) four elongated leg shanks mounted axially along a circumferential center of a cylindrical base-ring;
- and
- (b) said cylindrical base-ring having a diameter wherein said diameter is substantially equal to diameter of a circumferential center of a graphitic packing seal ring and said base-ring being penetrated by a first axial slit positioned equidistant between any two adjacent elongated leg shanks.
A graphitic packing seal ring removal tool comprising:
- (a) a cylindrical base-ring having a circumferential center, and having sidewalls with surfaces having means for gripping thereon;
- (b) four elongated leg shanks mounted axially along said circumferential center and spaced 90-degrees apart from each other;
- and
- (c) a first vertical slit in said base-ring running axially from top to bottom of said base-ring, said slit positioned equidistant between any two adjacent leg shanks;
- wherein said base-ring is sized in such a manner as to have approximately the same circumferential center as said packing seal ring, in order to cut down through a circumferential center of said seal ring.
