Definitions

  • Hydraulic machine comprising means for injecting a flow taken from a main flow
  • the present invention relates to a hydraulic machine of the type traversed by a main flow of water, comprising at least one blade profile of a turbine, having an upstream end and a downstream end, in the vicinity of which is formed at least one zone vortex or a zone of reduced pressure or a cavitation zone, the machine comprising means for injecting a flow taken from said main flow, unmodified with respect to the main flow, in said swirl zone or reduced pressure zone or cavitation so as to locally modify the main flow or increase the pressure in this zone.
  • Such a hydraulic machine is used, for example in a hydroelectric power plant.
  • the machine is installed on the water or is supplied with water from a tank into which flows one or more streams.
  • US-1 942 995 discloses a hydraulic machine of the aforementioned type, for injecting a flow taken from the main flow in the cavitation zone formed along the vanes of the wheel of the turbine.
  • outlets of the withdrawn flow are arranged to inject the flow in a direction substantially perpendicular to the direction of the main flow.
  • Such orifices do not make it possible to eliminate the swirling zones forming in the wake of the blades and also disturbing the general performance of the hydraulic machine.
  • One of the aims of the invention is to overcome these drawbacks by proposing a hydraulic machine to remove vortex zones forming in the wake of any blading profile.
  • the invention relates to a hydraulic machine of the aforementioned type, wherein the injection means comprising a pipe taking the flow of the main flow and making it lead into the downstream end substantially in the direction of the main flow.
  • the pipe comprises an inlet taking the flow of the main flow upstream of the vane profile and an outlet opening into the vortex zone or of reduced pressure or cavitation,
  • the injection means comprise a valve arranged in the path of the withdrawn flow, said valve being movable between an open position in which it allows the flow taken off the main flow to pass and a closed position in which it prevents the passage of the withdrawn flow,
  • the vane profile is at least one blade of a plurality of blades of a Francis turbine wheel, said vanes arranged between a ceiling and a belt, the flow being taken from the ceiling or from the belt by means of openings in said ceiling or in said belt, said flow opening into the downstream end of the at least one blade.
  • FIG. 1 is a schematic representation in section from above of a blade profile of a turbine according to the invention
  • FIG. 2 is a partial diagrammatic sectional representation of a Francis turbine according to the invention
  • FIG. 3 is a schematic view from above of the Francis turbine wheel of FIG. 2
  • the invention described below applies in particular to hydraulic machines of the Francis turbine type. These machines being known, they will not be described in detail in the present description. The invention is also applicable to other types of hydraulic machines in which problems of formation of swirling zones, reduced pressure or cavitation arise.
  • upstream and downstream are defined with respect to the direction of flow of the main flow E through the hydraulic machine.
  • a hydraulic machine member of the vane profile type 1 of a turbine is for example a front-director, a director or a turbine blade.
  • the vane profile 1 shown in FIG. 1 is a pre-director.
  • the forebolts and directors have the function of guiding a main flow E which passes through the wheel 4 of the turbine by licking blades 6, which causes the rotation of the wheel 4 about a vertical axis Z-Z '.
  • the vane profile 1 has an upstream end 8 and a downstream end 10 interconnected by side walls 12 licked by the main flow E. Whether for a front-director, a director or a turbine blade, a zone 14 swirling and / or reduced pressure is created in the vicinity of the downstream end 10, in particular immediately downstream of the downstream end 10, which can cause vibrations in the hydraulic machine.
  • the vane profile 1 comprises at least one duct 16 extending inside the profile between an inlet opening 18 and an outlet opening 20.
  • the inlet opening 18 is disposed in the vicinity of the end upstream 8 and opens for example into one of the side walls 12 of the vane profile 1.
  • a portion Ei of the main flow E licking the side walls 12 is taken in the pipe 16 through the inlet opening 18 and is brought to the outlet opening 20.
  • the pipe 16 takes the flow E1 outside the blade profile 1 and conveys this flow to the outlet opening 20.
  • the outlet opening 20 opens into the downstream end 10.
  • the withdrawn flow Ei of the main flow E flows in the pipe 16 and is injected into the zone 14 through the outlet opening 20.
  • This has the effect of effect of modifying the properties of the flow E in the zone 14 and thus prevent the phenomena of vibration.
  • the blade 6, shown in FIG. 2 comprises other conduits (not shown) extending inside the blade between an inlet opening 22 and an outlet opening 24, 26.
  • the inlet openings 22 of the pipes are arranged in the vicinity the upstream end 8 of the blade 6 so as to take a flow of the main flow E upstream of the blade.
  • the outlet openings 24, 26 of the pipes are arranged to inject the flow taken from the side walls of the vanes 6 in the vicinity of the upstream end 8 and / or the downstream end 10 of the vane 6.
  • the flow taken and injected has the effect of locally modifying the main flow E and thus avoid the formation of cavitation phenomena on the blades profile.
  • Some pipes therefore comprise an outlet opening 24 opening into a side wall of the blade 6 in the vicinity of the upstream end 8 in order to avoid formation phenomena of cavitation on the blades in the vicinity of the upstream end 8.
  • Other conduits comprise an outlet opening 26 opening into a side wall of the blade 6 in the vicinity of the downstream end 10 in order to avoid formation phenomena cavitation on the blades in the vicinity of the upstream end 10.
  • the inlet and outlet openings may be arranged in series along the upstream end 8 and the downstream end 10 of the blade 6 in a direction that may be perpendicular to the direction of the main flow E, as represented by the outlet openings 24 of FIG. 2.
  • outlet openings are arranged so as to open into the downstream end 10 of the blade 6 in the direction of the main flow E.
  • the openings open for example into the base of the dawn 6. The injection of the flow taken from the downstream end makes it possible to eliminate the vortex zone which forms in the wake of the blades 6.
  • the blades 6 of the wheel 4 are arranged between a ceiling 28 and a belt 30.
  • the phenomena of cavitation on the vanes can also be prevented by openings 31 made in the ceiling 28 facing the vanes 6, as shown in FIG. 3. These openings 31 communicate with the outlet openings 24, 26 and / or with the outlet openings 20 opening into the downstream end 10 by means of pipes not shown.
  • a flow E 2 is taken from the main flow E and passes through spaces between the fixed part of the turbine and the blades 6 mobile.
  • the withdrawn flow E 2 is taken from the annular space 34 situated above the ceiling 28.
  • This flow E 2 passes through the openings 31 and then is guided towards the outlet openings 24, 26 and / or 20.
  • cavitation phenomena on the blades it can also occur vortex formation phenomena in the space 33 between the blades 6.
  • the problem of forming a vortex between the vanes 6 is solved by means of orifices 32 made in the ceiling 28, as shown in FIG. 2.
  • the flow E2 taken upstream of the blades 6 in the annular space 34 passes through the openings 32 and feeds the spaces 33 between the blades 6, as shown in FIG. 3.
  • the openings 32 are distributed in the ceiling 28 opposite the spaces 33 between the blades 6.
  • the withdrawn flow E2 can pass through the belt 30 by means of openings (not shown) formed therein.
