Definitions

  • the distribution components of a turbine comprise a fixed distributor and a movable distributor for adjusting the discharge between complete closure and full opening.
  • adjustable pump diffusers comprise a movable section which may be positioned so as to adopt energy recovery to various pump operating conditions. The movable part of such adjustable pump diffusers bears on the concave side of the fixed unit.
  • Turbine-pumps built on the turbine principle to have a fixed distributor and a movable distributor are also known, but in such machines the two distributors thereof have heretofore been constructed to be partly imbricated within each other, i.e., overlapped partly.
  • the primary purpose of the present invention is to provide a movable distributor which will decrease the operational loads so that this type of unit may be used in turbine pumps operating under very high heads.
  • this purpose is accomplished by making the guide vanes of the movable distributor short, and so arranging them with relation to the fixed guide vanes of the fixed distributor, that when the machine operates as a pump, such movable guide vanes will bear on the ends of the convex side of the fixed guide vanes, and when the machine operates as a turbine, such movable guide vanes will pivot in the direction which increases the opening necessary to ensure suitable distribution of water over the impeller.
  • FIG. 1 is a horizontal sectional view showing the guide 'vanes of the fixed and movable distributors of a pump-turbine designed to operate under very high heads;
  • FIG. 2 is a similar view of a modification of the vane construction shown in FIG. 1.
  • the reference numeral 1 designates generally the fixed guide vanes of usual construction provided in the fixed distributor of a pump-turbine. As indicated, such fixed guide vanes are segmently-shaped with one convex side surface and a concave side surface.
  • the movable distributor of the machine is provided with an equal number of movable guide vanes 2 of a thickness substantially equal to that of the fixed guide vanes.
  • Each of the movable guide vanes is rotatable about the axis of a vertical shaft 3 located beyond the trailing end of the associated fixed guide vane.
  • each vertical shaft 3 is determined by the mechanical problems which must be taken into account due to the location of such shaft in the movable vane 2 and by the correct positions for the movable vanes when closed and open to attain good hydraulic flow conditions.
  • the shafts 3 are connected in a conventional manner to a shifting ring for positively moving the movable guide vanes to all positions required of such vanes in the operation of the machine and only two of which are shown in the drawings.
  • such connecting means may include a lever 15 connected to each shaft 3 and in turn connected by alink 16 to a shifting ring 17 which may be actuated by a servo-motor (not shown) by means of a rod (not shown) connected tangentially to the shifting ring 17.
  • the movable guide vanes are very short in comparison with the fixed guide vanes and are too short to cooperate with one another to close the movable distributor, or with the fixed guide vanes to close the passageways 9 between the latter.
  • the axes of the movable guide vanes 2 are so located with respect to the trailing terminal ends of the fixed guide vanes 1 that in one position thereof the side surfaces 12 of their leading ends 4 bear against the convex surface of the trailing ends 5 of the fixed guide vanes. In this position of the movable guide vanes they cannot be used to close the distributor. The movable guide vanes will assume this position when the machine operates as a pump with water flowing in the distributor passages 9 in the direction of the arrows F.
  • each movable guide vane 2 will form an extension of the trailing end of the associated fixed guide vane 1 and its side surfaces 8 and 10 are configured to provide a substantial continuation of respectively, the convex and concave side surfaces of the associated fixed guide vane 1, thereby affording no obstruction to the flow of water in the direction F. Since in this position the side surfaces 12 of the leading ends 4 of the movable guide 2 will be pressed finnly against the convex surfaces of the trailing ends 5 of the fixed guide vanes, during such flow of water in the direction F, they will be rendered immovable to any torque fluctuations which might otherwise cause vibration, and will not respond to any hydraulic forces exerted on them tending to cause vibra tion thereof.
  • each movable guide vane 2 is so configured that when such vane is pivoted to the position indicated in dotted outline to increase the opening necessary to obtain a suitable distribution of water over the impeller 11, the opening defined by such side surface 12 and the convex end 5 of the associated fixed guide vane will ensure such distribution without diminution of efficiency.
  • each movable guide vane 2 forms a joint with the associated fixed guide vane to provide what may be considered as a composite fixed guide vane when the machine is operating as a pump.
  • each sloping shoulder 7 is given a configuration which will cooperate with the movable vane side surface 12 opposing it to provide a suitable passageway for the bypassing additional flow of water when the machine operates as a turbine, as indicated by the dotted line position 6 of the movable guide vane.
  • a reversible pumpturbine comprising a distributor including fixed guide vanes arranged in circumferentially spaced relation around the impeller of the turbine-pump and having outer convexly-shaped sides directed away from the impeller, mobile guide vanes, means for supporting each mobile guide vane intermediate its length for pivotal movement about a fixed axis located in adjacently spaced relation to the trailing end of an associated fixed guide vane, said location of such axis being such that when the reversible pump-turbine is to be operated as a pump the leading end of said mobile guide vane is enabled to be advanced inwardly to ward and into contact with the inner trailing end of said associated fixed guide vane reducing the opening between said associated fixed guide vane and that adjacent fixed guide vane which has its side thereof directed toward the impeller disposed in opposed relation to said convexly-shaped side of said associated fixed guide vane, and when the reversible pumpturbine is to be operated as a turbine the lending end of said mobile vane is enabled to be retracted outwardly from said
