Definitions

  • the invention relates to a hydraulic flow machine for energy conversion for the energy supply of energy consumers of all kinds.
  • the drive power of a pump is required to set the paddle wheel in rotation, whereby the atmospheric air pressure presses the water column into the suction pipe and from there into the impeller.
  • the water must be redirected from the direction of flow in the intake manifold to the direction of flow in the impeller.
  • the torque on the impeller and the centrifugal force the water within the blade channels of the impeller must be accelerated and transported from the lower circulation speed existing in the center of the impeller to the circulation and exit speed required on the outside diameter.
  • the acceleration forces required for this must be provided by the drive of the pump.
  • the water hits a fixed stator of the pump or in a spiral housing, which converts the speed at which the water exits when the impeller emerges into pressure energy.
  • the water is led out of the volute casing into a pressure connection, in which it determines the drive power of the impeller from the head and the delivery volume of the water / per unit of time as well as from the energy losses.
  • An essential feature of the conventional centrifugal pump is that the drive power of the motor is not used for the flow power flowing into the impeller.
  • the drive motor accelerates the water flowing into the impeller to the outlet speed of the water flowing out of the impeller. Due to the centrifugal force of the impeller circulating water creates a negative pressure compared to the pressure prevailing at the intake pipe inlet.
  • the resulting excess pressure at the intake manifold inlet causes the water in the intake manifold to rise and flow into the impeller.
  • part of the total head of the centrifugal pump does not come from the power of the drive motor, but from the excess pressure at the intake manifold.
  • water turbines e.g. B. Francis turbines
  • the hydropower plants use the energy of pent-up water by means of water turbines to generate electricity in generators.
  • the performance of these turbines increases directly with the head and amount of water.
  • the head is reached by the damming of flowing water, for example large rivers.
  • the energy conversion takes place in the blades of the turbine idlers and impellers.
  • the water flowing into the guide vanes is first accelerated in the guide vanes to the entry speed in the impeller.
  • An increase in the speed of the water is achieved in that the outlet cross sections of the guide vanes are narrowed by a corresponding angular design with respect to the inlet cross sections of the guide vanes.
  • a torque is generated on the turbine shaft by the action of the supplied flow energy on the impeller blades. This is the working capacity of a water flow driving the turbine impeller.
  • the hydropower plants described are localized and require considerable investment costs. The amount of water available can fluctuate greatly due to the seasonal variation in the amount of water available, which in turn has a major influence on the amount of energy available or to be supplied by consumers.
  • the invention is therefore based on the object of creating a hydraulic fluid flow machine which uses only the flow power caused by the atmospheric air pressure of a water column rising to an impeller in a suction space and makes it available to a consumer as final energy.
  • the object is achieved by a hydraulic fluid machine with the characterizing features of claim 1.
  • annular water circuit within a trough-shaped flow space, which is arranged coaxially around the axis of the generator in a container with a required water supply.
  • the outer guide wall of the trough-shaped flow space forms, together with two inner guide walls, a suction space and a guide space, between which the impeller, which is arranged on the axis of the generator and rotates horizontally about this axis, is guided with impeller blades, all components together forming the annular water circuit.
  • the atmospheric air pressure can act on the water level and a compensating tube arranged between the flow space and the container enables the water level in the trough-shaped flow space to be regulated.
  • the atmospheric air pressure exerts a pressure on the water level in the trough-shaped flow space and, due to the negative pressure generated by the impeller, causes the water to rise in the suction space, via the guide vanes into the impeller, which rotates horizontally around the axis of the generator, and from there into the control room is directed where it can be redirected and returned to the suction room.
  • the speed energy of the exit speed of the water from the impeller is added to the pressure energy of the atmospheric air pressure and by narrowing the cross-section in the guide vane area, the water is accelerated again to the required entry speed into the impeller.
  • the drive motor keeps the impeller and the generator at a certain speed, which over the Circulation speed of the water in the impeller creates centrifugal force at the inlet openings of the impeller and a negative pressure at the outlet openings, which corresponds to the counter pressure at the outlet openings and is directed in the opposite direction.
  • a second variant of the hydraulic fluid machine according to the invention provides that, in the event of a reduced outlet velocity of the water from the impeller due to a desired lower flow velocity in the guide and suction space, an acceleration wheel rotating horizontally with the impeller around the axis of the generator is provided instead of the guide vanes which prevents atmospheric air from entering the suction chamber.
  • the level of the water level in the container and its regulation, according to claim 2 by known methods such as manually through a viewing window or via appropriately arranged floats or via sensors which trigger a signal when a determinable level is reached and by a water inlet adapted to the application conditions. and water drainage system can be optimally determined.
  • arranged contactless seal ensures the trouble-free ring-shaped water cycle.
  • the amount of energy to be delivered by the hydraulic fluid machine according to the invention is determined by the structural sizes of the individual components and by measuring the drive power for the energy supply in the start-up phase of the system and to compensate for the system-related losses, the yield of final energy being greater in the hydraulic fluid machine with guide vanes is as with the acceleration wheel, because additional energy losses are recorded by the acceleration wheel.
  • the machine works absolutely independent of the time of day or season, enables cost-effective energy storage, is absolutely environmentally friendly due to the use of atmospheric air pressure as primary energy and does not generate any waste. It requires no water gradient, no natural and / or dammed water source and is therefore not tied to a specific location.

Abstract

L'invention concerne une turbomachine hydraulique pour convertir l'énergie. L'invention vise à réaliser une turbomachine hydraulique qui utilise exclusivement la puissance d'écoulement conditionnée par la pression atmosphérique (pL) d'une colonne d'eau montant vers un rotor (3) à partir d'une chambre d'aspiration (1) et qui la met à disposition d'un consommateur sous forme d'énergie finale (EN). A cet effet, la turbomachine comporte un circuit d'eau annulaire coulant dans un sens radial par rapport à l'axe d'un générateur (6), ce circuit étant doté d'un espace de guidage (7) et disposé, à l'intérieur d'une chambre d'écoulement (8) en cuvette, dans un contenant (9) de manière coaxiale par rapport à l'axe du générateur (6). Le rotor (3) tourne horizontalement par rapport à l'axe. La différence énergétique entre l'énergie introduite sur le rotor (3) et l'énergie produite par ce dernier correspond à la somme de l'énergie apportée par la pression atmosphérique (pL) et par le moteur d'entraînement (Em). L'énergie alimentée par le moteur d'entraînement (5) est ensuite de nouveau mise à disposition par le générateur (6).
