Abstract
A vacuum pump having components that are subject to wear may be adjusted to compensate for the wear. In some instances, a vacuum pump may include a housing and an impeller disposed at least partially within the housing. A gap between the housing and the impeller may be adjustable to compensate for wear. In some cases, the housing may include a ring that may be moved to adjust a tolerance (or gap) between the ring and the impeller. In some instances, the ring may be rotated to adjust this gap. In other instances, the ring may be translated to adjust the tolerance.
Claims31
A liquid ring vacuum pump comprising:
- a base plate;
- a concentric ring disposed adjacent the base plate such that the concentric ring may be translated relative to the base plate;
- an impeller disposed within the concentric ring;
- and
- a cover plate disposed over the concentric ring, the cover plate secured to the base plate.
A liquid ring vacuum pump comprising:
- a base plate;
- a ring disposed adjacent to the base plate;
- and
- an impeller disposed within the ring;
- wherein the ring is translatable relative to the impeller to define an adjustable tolerance therebetween.
A method of compensating for wear within a liquid ring vacuum pump comprising a base plate, a ring disposed proximate the base plate, an impeller disposed within the ring and a cover plate disposed over the ring, the method comprising the steps of:
- loosening the cover plate;
- translating the ring relative to the impeller;
- and
- tightening the cover plate.
A liquid ring vacuum pump comprising:
- a housing;
- and
- an impeller disposed proximate the housing;
- wherein the housing is configured to be movable relative to the impeller to change a tolerance defined between the impeller and the housing.
A method of adjusting a liquid seal vacuum pump comprising a housing and an impeller disposed proximate the housing, the method comprising the steps of:
- loosening at least a portion of the housing;
- moving the loosened portion of the housing to obtain a desired tolerance between the housing and the impeller;
- and
- tightening the loosened portion of the housing.
