Abstract

1300148 Hydraulic turbines; centrifugal pumps ATELIERS DES CHARMILLES S A 10 Feb 1970 [19 Feb 1969] 6219/70 Headings F1C and FIT In a turbine, pump or pump-turbine, comprising a casing having a rotor therein, the clearance gap between the casing and a peripheral part of the rotor is adjustable either to a minimum value for normal running of the machine, or to a larger value for dry running of the machine. During normal running of the hydraulic turbine shown having, e.g. a casing part 7 of about 1700mm diameter, steel casing rings 14 are externally subjected to pressure fluid (e.g. of 300Kg/cm<SP>2</SP>) delivered through conduits 16 to cause the rings 14 to radially contract and produce the minimum clearance gap, e.g. of 0À8mm. During dry running, the rings are not subjected to the pressure fluid and thereby return to their relaxed state wherein they provide the larger clearance gap, e.g. of 1À6mm.
