Definitions

  • the invention relates to turbomachines comprising a pump, having an inlet and an outlet, and a hydraulic turbine which has an inlet and an outlet separate from those of the pump, which is mounted on the same shaft as the pump, the end of which high pressure is attached to the high pressure end of the pump and which communicates with it by their joined end.
  • a pump-turbine group called isogyre group
  • isogyre group of a great compactness
  • turbomachine gathers in the same assembly turning a turbine wheel and a pump wheel, leaning against each other, fixed on the same tree and served by the same entrance and the same exit.
  • Independent sleeve valves are arranged one at the inlet of the impeller, the other at the outlet of the pump wheel. These valves isolate one wheel when the other is working.
  • This group can operate either as a pump or a turbine, but not both.
  • turbopump according to the invention which is also very compact, differs radically from this prior type of pump-turbine group in that the operation in hydraulic turbine and that in pump takes place simultaneously, the operation in hydraulic turbine recovering energy, especially for the needs of the pump.
  • the turbomachine according to the invention is normally devoid of any means for interrupting the operation of the pump when the hydraulic turbine is operating or vice versa.
  • turbomachines of the type mentioned in the preamble to the main claim are described and intended to treat gases, in particular air.
  • turbomachines are not intended to treat liquids. In addition, they necessarily include bearings independently supplied with fluid, which complicates their manufacture and operation.
  • turbomachine of the type mentioned in the preamble to the main claim but intended to treat a liquid and characterized in that it comprises an intermediate part of revolution which defines, between an internal lateral face and an external lateral face , a pump volute and a hydraulic turbine cover on either side of a plane perpendicular to the lateral faces and which supports a hydrostatic bearing whose chamber communicates with the pump.
  • the liquid leaving the pump can go to a treatment installation and then return from it, possibly having a modified formulation and state, but while still under pressure, enter the hydraulic turbine to drive the shaft and therefore contribute during pump operation.
  • the turbomachine should only be made tight vis-à-vis the outside, in the axial direction, at its free ends being at low pressure.
  • the pumped liquid itself is used as the bearing fluid, which makes it possible to put a bearing in the most desired position in the center of the machine while also recovering the energy of the liquid necessary for the bearing on the hydraulic turbine. This greatly simplifies the bearing supply circuits whose lift is established by varying the pressure difference of the liquid at the outlet of the pump and at the inlet of the hydraulic turbine.
  • a driving machine providing additional energy for pumping can attack the common tree.
  • this machine is arranged on the side of the free end of the pump, so that the latter receives energy from both sides.
  • the turbomachine shown essentially comprises a shaft 1 driving in rotation impellers housed in a stationary pump 2 and turbine wheels housed in a stationary hydraulic turbine 3, these two elements being joined by their high pressure ends.
  • the pump 2 at the free end, has a radial inlet opening 4 opening out in front of an impeller 5 followed by a diffuser 6 of a first stage, which is followed by four identical stages, except that the scroll 7 forming the top stage diffuser is formed in an intermediate piece 8 of revolution having an external lateral face 9 and an internal lateral face 10.
  • a radial opening 11 at the outlet of the pump 2 opens into the volute 7.
  • the intermediate piece 8 also defines a cover 12, opening onto a first turbine wheel 13, symmetrical with the pump volute 7 with respect to a plane perpendicular to the 'axis of the shaft 1.
  • the fixed part 8 supports the shaft 1 by means of a hydrostatic bearing 14, the chamber 15 of which communicates by a labyrinth 16 with the adjoining end of the pump 2 and by a conduit 17 low pressure return with the adjoining end of the hydraulic turbine 3.
  • This opening 18 is diametrically opposite the opening 11 can be be perpendicular to it.
  • a radial opening 19 for output from the hydraulic turbine At the free end of the hydraulic turbine 3 is formed a radial opening 19 for output from the hydraulic turbine.
  • the entire hydraulic package 2, 3, 8 is held by fasteners 20, while at each free end of the turbomachine, oil bearings 21 and sealing parts 22 are provided.
  • Sea water arrives through the suction opening 4 of the pump 2 under a pressure Po. It passes through the pump 2 and exits through the opening 11 of the pump 2 discharge under a pressure P1> P0. It is sent to a reverse osmosis installation (not shown) from which it partially returns under a pressure P2> P to enter the hydraulic turbine 3 through the inlet opening 18. It emerges through the opening 19, after having passed through the hydraulic turbine 3, under a pressure P3 much lower than P2, thus having yielded energy, which makes it possible to drive the shaft 1 and thus contributes to operating the pump 2. The energy saving obtained can reach 50%.
  • a driving machine 23 drives the shaft 1 by a coupling 24.
  • the pump 2 is interposed with the hydraulic turbine 3 and the machine 23.
