ABSTRACT:
Liquid ring pumps with rotating canisters are supported by at least one radial fluid bearing pad. The bearing fluid is either a gas or a liquid. The radial fluid bearing pads can be of either the hydrodynamic or hydrostatic type. Holes in each bearing pad are used to introduce bearing fluid to the clearance between the rotating canister and the housing of the pump. Each radial bearing pad can be mounted to the housing using a ball joint or a bladder. Access ports formed in the housing provide access to the radial bearing pads. Axial fluid bearings are mounted to the housing using shims or threaded bolts so that the axial position of the axial bearings can be adjusted.
