Definitions

  • This invention relates to water turbines of the type in which the vanes occupy only a circumferential ring surrounding a relatively large free central space traversed by the water jet which both enters and is discharged by the outer ends of the vanes.
  • the object of the invention is to provide a turbine of that type which will receive and efliciently utilize the energy of largely variable quantities of water, and which will not suffer any essential loss of efficiency, when back-surge or reflux takes place as a result of congestion in the discharge passage.
  • Another object of the invention is to increase the draught capacity and the output of such turbines.
  • the interior of the turbine drum a-- carrying vanes -Z)- is entirely free, except that the shaft c extends along the axis of the drum.
  • the drum is enclosed in a casing -(Z comprising also the admission and discharge channels marked -cZ and d respectively.
  • the chute forming the back of the admission channel has the form of a logarithmic spiral in order to convey all threads of the water stream at substantially equal angles and on the shortest way onto the vanes.
  • aa flap --e is arranged in the admission channel (Z
  • the quandrangular shaft-e of this flap is rotatably mounted in the side walls of thecasing --.-cZ-
  • One end of the shaft -6 projects beyond the side Wall of the casing -(Z-- and is there associated with known'means'for rotating and fixing it in the several positions of rotation.
  • the blade of the flap cforms a continuation of the front wall of the admission channel (Z in the shape of alogarithmic spiral.
  • the hub of the flap has a lug e which strikes against a stop surface on the casing when the flap reaches its extreme position corresponding to the maximum admission.
  • the stream lines -'-f indicate the paths of the several Water threads.
  • the flap In the position of the flap eas shown in Fig. l, the flap will serve to determine only the thickness of the admitted stream so that the latter is guided only on the one side by the chute. Practical experience has confirmedthat for a thin stream of water such one-sided guidance suffices.
  • ⁇ Vhat I claim is 1.
  • a water turbine comprising a drum having a series of vanes occupying a circumferential ring portion of said drum and a free central space surrounded by said vanes, a shaft in the centre of said free space, and an admission channel having guiding walls so curved as to direct all threads oi the water stream at substantially equa angles onto a circumferexr tial portion of the drum, with regulating means permitting the arc of admission to be amplified to such an extent that the shaft is flooded by the stream traversing said central space.
  • a water turbine comprising a drum having a series of vanes occupying a circumferential ring portion of said drum and a free central space surrounded by said vanes, a shaft in the centre of said free space, and an admission channel having guiding walls so curved as to direct all threads of the water stream at substantially equal angles onto a circumferential portion of the drum, with regulating means permitting the arc of admission to be amplified to such an extent that the water stream fills out said central space.
  • a Water turbine comprising a drum having a series of vanes occupying a circumferential ring portion of said drum and a free central s ace surrounded by said vanes, a shaft in t 1e centre of said free space, an admission channel having guiding walls so curved as to direct all threads of the water stream at substantially equal angles onto a circumferential portion of the drum, and a discharge channel joined to another circumferential por tion of the drum, with regulating means permitting the arc of admission to be ampli; lied to such an extent that discharge takes place through all such passages between said vanes as have direct communication with said discharge channel.
  • a water turbine comprising a drum having a series of vanes occupying a circumferential ring portion of said drum and a, tree central space within said series of vanes, a shaft in the centre of said space, an admission channel having its back wall curved near the drum in the form of a loga rithmic spiral, and an adjustable flap post. tioned in said admission channel so as to form a continuation of the front wall of said channel the shape of a logarithmic spiral.
  • a water turbine comprising a drum having a series of vanes occupying a circumferential ring portion of said drum and a tree central space within said series of vanes, a shaft in the centre of said' space,
  • an admission channel having its back wall curved near the drum in the form of a logarithmic spiral, and an adjustable flap positioned in said admission channel so as to form a continuation of the front wall of said channel in the shape of a logarithmic spiral and permit the arc of admission to be amplified to such an extent that the shaft is flooded by the stream traversing said central space.
  • a water turbine comprising a drum having a series of vanes occupying a circumferential ring portion of said drum and a free central space Within said series of vanes, a shaft in the centre of said space, an admission channel having its back wall curved near the drum in the form of a logarithmic spiral, and an adjustable flap positioned in said admission channel so as to form a continuation of the front wall of said channel in the shape of a logarithmic spiral and permit the arc of admission to be amplified to such an extent that the water stream fills out said central space.
  • a water turbine comprising a drum having a series of vanes occupying a circumferential ring portion of said drum and a free central space within said series of vanes, a shaft in the centre of said space, an admission channel having its back wall curved near the drum in the form of a logarithmic spiral, a discharge channel joined to a circumferential portion of the drum opposite the mouth of said admission channel, and an adjustable flap positioned in said admission channel so as to form a continuation of the front wall of said admission channel in the shape of a logarithmic spiral. and permit the arc of admission to be amplified to such an extent that discharge takes place through all such passages between said vanes as have direct communication with said discharge channel.
