Abstract

A hydraulic pump or reversible pump-turbine comprises valve means for substantially blocking communication between the impeller and the suction tube during priming of the pump or of the reversible pump-turbine in operation as a pump. Pumping operation of a pump or pumpturbine is started by a procedure which is substantially the same as that described in Specification 1,006,299, but the means for controlling the power absorption comprises a valve in the suction tube for substantially blocking communication between the impeller and the suction tube. To ensure that the pressure above the valve is always approximately equal to the pressure below it, the valve does not seal tightly in the suction tube. Fig. 2 shows one form of valve, comprising an annular series of sectorial shutters 36, each pivoted in bearings in the wall of the suction tube 20 and in a central fairing 37, the shutters being movable in unison, as by a hydraulic jack, through a control ring 41 acting on crank arms 40. During the starting of the pump, the shutters 36 are closed at or before the stage at which the air in the impeller 11 begins to be progressively replaced by water. During the final removal of the air, the power absorbed by the pump rises rapidly at a rate which tends to be difficult to control. However, the shutters 36, by maintaining the flow in the impeller 11, above the shutters, substantially separate from the flow in the suction tube 20, below the shutters, controls the rate of increase of power absorption to an acceptable value, whereby this phase of the starting operation is spread over a period of 20 seconds instead of a fraction of a second. In alternative forms of the valve, the shutters 36 are replaced by a butterfly valve pivoted about a diameter, or a pair of semi-circular flaps pivotal in opposite directions about their common diameter. As a further alternative, there may be used a sluice gate which is movable into the suction tube in a direction transverse to the axis of the suction tube.
