Two-stage,vortex-type centrifugal compressor or pump

Abstract

Abstract A ROTOR IS ENCLOSED BY A HOUSING ROTATABLE PREFERABLY ABOUT A HORIZONTALLY EXTENDING CENTRAL AXIS, THE ROTOR HAVING A CENTRAL FIRST STAGE SPINDLE AND AN ANNULAR SECOND STAGE SPINDLE SPACED OUTWARDLY THEREFROM WITH FIRST STAGE BLADES BETWEEN THE SPINDLES AND SECOND STAGES BLADES PROJECTING RADIALLY OUTWARDLY FROM THE SECOND STAGE SPINDLE. RADIALLY SEPARATED ANNULAR FLUID CAVITIES, PREFERABLY SUBSTANTIALLY TOTALLY ARCUATE IN RADIAL CROSS SECTIONS, ARE FORMED IN THE HOUSING AXIALLY ADJACENT EACH SIDE OF THE ROTOR AXIALLY ALIGNED WITH AND OPENING INTO THE ROTOR FLUID CAVITIES FORMED BETWEEN THE FIRST AND SECOND STAGE ROTOR BLADES. THE SECOND STAGE SPINDLE IS FORMED ARCUATELY INWARDLY ALONG THE FIRST STAGE ROTOR BLADES EITHER PARTIALLY OR TOTALLY DIVIDING THE FIRST STAGE ROTOR FLUID CAVITIES INTO AXIALLY ADJACENT PARTS, EACH PART WITH ITS ASSOCIATED HOUSING FLUID CAVITY FORMING A COMBINED CAVITY PART APPROACHING CIRCULAR IN RADIAL CROSS SECTION. THE SECOND STAGE SPINDLE IS SIMILARLY FORMED ARCUATELY OUTWARDLY ALONG THE SECOND STAGE BLADES AND PREFERABLY TO RADIALLY ADJACENT SIMILAR INWARD PROJECTIONS OF THE HOUSING TO PROVIDE TWO OR THREE AXIALLY ADJACENT, COMBI NED ROTOR AND HOUSING SECOND STAGE FLUID CAVITIES, EACH APPROACHING CIRCULAR IN RADIAL CROSS SECTION. A FLUID THAT INLET IS FORMED THROUGH THE HOUSING FROM ONE OR BOTH SIDES OF THE ROTOR INTO THE HOUSING FIRST STAGE CAVITIES, AXIALLY ALIGNED FLUID COMMINICATIONS IN THE HOUSING AT THE SIDES OF THE ROTOR BETWEEN THE FIRST AND SECOND STAGE HOUSING CAVITIES, AND A FLUID OUTLET UPWARDLY THROUGH THE HOUSING FROM ALL OF THE SECOND STAGE HOUSING CAVITIES, THE FLUID INLETS AND OUTLETS PREFERABLY BEING IN THE LOWER PORTION OF THE HOUSING. WHERE NECESSARY, A COOLING FLUID CHANNEL MAY BE FORMED AROUND THE HOUSING OUTWARDLY OF THE SECOND STAGE FLUID CAVITIES AND RADIALLY ALIGNED WITH ALL OF SAID CAVITIES.
