Abstract

PURPOSE: To permit a pumping rate of discharge and head of a pump to be freely changed without the need for displacement of a motor or a turbine, by attaching a wearing ring shifting mechanism which can axially move wearing rings with respect to a turbine to a pump casing.
CONSTITUTION: Annular wearing rings 25 and 26 are fitted in spot facing holes of inner wall of a casing 3 disposed inside a turbine 1 without forming any clearances around their circumference so that they can move in the line of the axis of a pump shaft 2. When a wearing ring shifting mechanism 29 is actuated for increasing or decreasing a clearance between the wearing ring 25 and the turbine 1, an amount of liquid which will run from a vortex chamber 10 to a suction port 9 is increased or decreased, whereby a flow rate, pressure and pumping head of liquid discharged under pressure are reduced or accelerated. Incidentally, the clearance between the wearing ring 26 and the turbine 1 should be adjusted as narrow as possible by another wearing ring shifting mechanism 29.
