Title:
VESSEL CENTERING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO2002034392
Kind Code:
B1
Abstract:
A vessel centering system comprises a vessel, an annular, spacer member, a fastening element, and an elastomeric component. The vessel includes an outer surface and a vessel groove formed on a circumference of the vessel outer surface. The spacer member is fitted in the vessel groove and extends outwardly with respect to the vessel. The first and second lateral end surfaces define a spacing therebetween. The spacer member includes a tangential bore and an annular groove. The tangential bore extends along a line generally tangential to a curvature of the spacer member. The fastening element, which could be a screw, is disposed in the tangential bore in engagement with the ring member and extends across the ring spacing. The elastometric component, which could be a gasket or O-ring, is disposed in the annular groove. A plurality of biased bearings can be provided instead of the elastomeric component. When the vessel is installed in the aperture of a vessel plate, concentricity between the inner surfaces of the vessel and a shaft extending into the vessel is easily obtained.
