Abstract
In liquid ring pumps having rotating lobe liners supported by a bearing fluid in an annular clearance between the liner and the surrounding housing, the housing has at least one substantially annular channel formed in the housing for distributing the bearing fluid to a plurality of circumferentially spaced apertures extending through the housing from the channel to the clearance.
Claims26
A liquid ring pump comprising:
- a stationary annular housing having a central longitudinal axis surrounded by said housing;
- a rotor disposed in said housing for rotation about a rotation axis which is substantially parallel to said longitudinal axis;
- an annular liner member disposed in said housing concentric with said longitudinal axis, the radially outer surface of said liner member being spaced from the adjacent inner surface of said housing by an annular clearance;
- means for maintaining a quantity of pumping liquid in said housing, said pumping liquid being formed into a recirculating annular ring inside said liner member by rotation of said rotor;
- and
- means for introducing a bearing fluid into said annular clearance so that said liner member rotates on said bearing fluid about said longitudinal axis as a result of recirculation of said pumping liquid in said annular ring, said means for introducing comprising at least two circumferentially spaced apertures in said inner surface of said housing, a channel extending through and enclosed within said housing between said at least two apertures, and means for supplying bearing fluid to said channel so that said bearing fluid flows through said channel and enters said annular clearance via said apertures.
