Definitions

  • centripetal wheel of the turbine is done by a constant opening injection sector whose fixed guide vanes impose on the fluid a suitable orientation.
  • the invention claimed below makes it possible to maintain the yield at its optimum value whatever the flow rate of the fluid and its application covers both the recovery of energy by expansion of gas at high pressure and that by expansion of water vapor. . In addition, it simplifies the installation upstream of the machine by replacing the flow control valve, high cost and generating energy loss, by a simple shut-off valve.
  • the invention essentially consists of a device making it possible to vary the sector of injection of the fluid without appreciably modifying the speed of the latter even if the flow rate undergoes significant fluctuations.
  • This device comprises a regulator provided with a variable injection sector, the opening of which is adjusted according to the characteristics of the fluid conveyed.
  • adjustable guide vanes controlled by a servo-motor whose action is proportional to the flow rate observed, are oriented so as to obtain an adequate passage section.
  • a high-pressure body 1 conveys the fluid to introduce it radially by an injection sector 2 extending, in this example, over an arc of approximately 140 °.
  • This injection sector 2 comprises, in the central zone, three fixed guide vanes 3, a first group of four guide vanes 4A, 5A, 6A, 7A each orientable by rotation around a pivot 4P, 5P, 6P, 7P and each controlled by an arm 4B, 5B, 6B, 7B secured at dawn and terminated by a roller 4R, 5R, 6R, 7R.
  • These rollers are guided by a groove 8 formed in a control ring 9 concentric with a discharge cylinder 10 whose axis coincides with that of the machine.
  • This injection sector 2 also includes a second group with three guide vanes IIA, 12A, 13A each orientable by rotation around a pivot 11P, 12P, 13P, each controlled by an arm 11B, 12B, 13B secured at dawn and ended with a roller 11R, 12R, 13R.
  • These rollers 11R, 12R, 13R are guided respectively by the grooves 14, 15, 16 of the control ring 9 which, by means of a linkage 17, is actuated by a servo motor not shown.
  • FIG. 1 represents the injection sector 2 in the position corresponding to the minimum flow rate of the fluid. The latter is expanded by passing through the three channels formed by the three fixed guide vanes 3 and the orientable guide vane 11A.
  • the control crown 9 rotates, clockwise, by an angle proportional to the increase in flow and the guide vanes orientable open successively and gradually depending on the position of the rollers on the ramps of the guide grooves.
  • the steerable guide vane 4A gradually pivots according to the progression of the roller 4R on the ramp 8R of the groove 8 formed in the control crown 9.
  • the orientable guide vane 11A begins its rotation before the total opening of the orientable guide vane 4A.
  • the opening control of the adjustable guide vanes 4A, 5A, 6A is carried out by the single ramp 8R of the groove 8 while the opening control of the vanes 11A, 12A, 13A is made by the ramps 14R, 15R, 16R belonging respectively to the grooves 14, 15, 16 formed in the control ring 9.
  • This control ring 9 consists of two co-axial plates 18, 19 of the same diameter, made integral with one another and carrying one 18 the guide grooves 8 and 15 and the other 19 the grooves of guidance 14 and 16.
  • the injection sector may extend over a different arc from that shown in FIG. 1. It is even possible to obtain an injection of the fluid over an opening of the order of 360 °. It is also possible that the order of opening of the orientable guide vanes takes place according to another process. For example, contrary to FIG. 1 where the progressive opening of the injection sector is done by extension of a central zone widening on either side of a minimum opening, an opening can be made. progressive spreading on one side of the minimum opening.
  • FIG. 3 represents the orientable guide vane 4A in the fully open position while the orientable guide vane 5A is still completely closed.
  • all the blades have an aerodynamic profile in the shape of a very flat triangle.
  • the base of this triangle determines with its long side an edge which is the trailing edge of the blade and with its short side another edge which constitutes the leading edge of the blade.
  • the apex of the triangle is rounded according to a curvature concentric with the pivot of the blade so as to determine a range on which the trailing edge of the neighboring blade can bear. This range, called neutral zone, allows the neighboring blade to keep the same position whatever the orientation of the blade on which it rests.
  • the orientable guide vane 5A rests by its trailing edge on the neutral zone of the guide vane orientable 4A. Therefore, the orientation of the steerable guide vane 4A can vary without changing the orientation of the steerable guide vane 5A.
  • This configuration makes it possible not to create parasitic openings, generating eddies which modify the flow of the fluid and reduce the efficiency of the fluid expansion.
  • FIG. 3 also shows an implantation of the pivots of the orientable guide vanes on the high-pressure body 1 so as to form converging channels, whatever the degree of opening of the vanes, to allow suitable relaxation of the fluids conveyed.
  • the steerable guide vanes shown in Figure 3 have two wings which, counted from the axis of the pivot of the blade, are of unequal sizes. This asymmetry allows by the play of pressures applied to the different faces of the triangle to obtain a resulting torque always acting in the same direction and to allow on the one hand to the whole linkage to work without shaking and on the other hand to the roller, located at the end of the arm, to remain applied to the same flank of the groove made in the control ring 9.
  • the result of the forces acting on the different forces of the orientable guide vane 6A results in a torque acting in the anticlockwise to apply the roller 6R on the lower side of the groove 8.
  • the regulator with variable injection sector equips the high-pressure body with a centriped turbine. It is obvious that the same device can equip both the high and low pressure bodies of this turbine.
