Abstract

The rotor (305) (Fig 5) of a hydraulic turbine is driven by jets from eight high pressure nozzles (261 to 268) (Fig 3, Fig 5) supplied via a pipe 89 from the delivery pipe 29 of a double multitubed accumulator arrangement (Figs 1 and 2). Each tube of each accumulator contains a piston 7 separating air in the upper part of the accumulator tube, from liquid in the lower part. Air is supplied to or removed from the upper parts of the accumulators by means of a vacuum pump 78 and forced draught fan 77 driven by an electric motor 81, via pipes 76, 79, 201. Liquid is supplied to the lower parts of the accumulators by means of a pump 87, drawing liquid from a tank 82 having baffles 100 to 105, and supplying liquid via a pipe 122. Liquid drained from the turbine is fed back to the tank 82 via pipe 85. The specification contains much detail of all parts of the plant and particular emphasis is given to the valving arrangements at the top and bottom of the accumulator arrangement. <IMAGE>
