Abstract

The working wheel of a turbine of a generator and of a pump is comprised of a rotary body having an arbitrary shape (5) and presenting arbitrary-shaped channels (7). The windows (14) of any working surface (19) may not be touching. In order to be homeostat, a guiding apparatus (27) is mounted after the working wheel of the generator turbine. In another form of execution, the radius r2 varies as a function of the turbine load. In a third form of execution, the group of turbines operates to the alternating medium motion without valves. The turbines may act as a generator, as a pump, as a transformer to transform an alternating motion into a rotary motion, as an automatic gear shifting box, as a recuperator. The efficiency of the turbines may reach 99 %.

Definitions: Turbine body: body formed by rotation of a certain curve [closed] around an axis (16).

[Hydrodynamic] turbine: a rotating body (5, 26, 27) comprising conduits (channels) (interacting with flows of a liquid or a gas).

Window (14) [inlet or outlet]: section of a channel (7) by a rotation surface of the turbine. 1: distance between two adjacent windows. Surface / body / work (17): trajectory of the virtual movement of the window / channel / around the axis (16).

Cross section (8) of the channel / (29) of the dawn /: section of the channel / of the dawn / of the minimum area passing through a certain point and not crossing the window; Q / F /: the sum of the areas of the cross sections of the channels / blades / (at the inlet, at the outlet or in the middle of the working wheel (5)). Median (10) of the channel / dawn /: set of centers of gravity (9) of all the cross sections of the channel / dawn /. (The median can be extrapolated to the intersection with the window.) Center (13) of the window: point of intersection of the extrapolated median (10) with the window (14). Nozzle (11): zone of the window channel (14) up to the first cross section (8). Radius r: distance from a certain point from the median of the channel to the axis of the turbine. Median (18) of the window: section of the window (14) through the surface (19) passing through the axis (16) of the turbine and the center (13) of the window.

Diameter d: external diameter of the working body. u: vector of the speed of rotation of a point on the working wheel. w: speed of rotation of the turbine. v: vector of the absolute speed of the flow leaving the working wheel with respect to the nozzle (11). a: angle (fig. 2) between the median (10) and the vector u [or - u].

Number N: number of channels.

Index "i" (where i = 1, 2, 3, 4, M) means: 1 - the input / output / of the generator wheel / pump /; 2 - the output / input / of the generator wheel / of the pump /; 3 - the exit / entry / from the entry / exit guide device / in case of a generator / pump /; 4 - the entry / exit of the exit / entry guide device / in the event of a generator / pump /; M - a point in the median (10) of the channel (7) between two nozzles 11, and 112.

The working body (5, 26, 27) of the present turbine belonging to a new class of turbines

[the class of channel turbines in which the channels (but not the blades) which work] consists of a rotating body of arbitrary shape (5 - Fig. 1) comprising a main / single channel or one of several / of arbitrary shape (7 - Fig. 1, 7, 11) with the nozzles (1 1) d: entry-soπιe almost rectiiigne (by compared to their extrapolated median (10)). Or, which is the same thing, that the turbine is composed of three independent parts r INPUT [with the parameters [r ₁ ; d ₁ ; Q ₁ : N ₁ ; β ₁ ; a ₁ ; l ₁ ]] taking a turbine, MEDIUM PART [with the parameters [r _M ; d _M ; Q _M ; N _M ]] taken from another turbine and EXIT [with the parameters [r ₂ ; d ₂ ; Q ₂ ; N ₂ ; β ₂ ; a ₂ ; l ₂ ]] intake of a third turbine; with this, the windows of one or two of the work surfaces touch or not (i _i ≥0). Such a turbine can be used in mobile (5) or stationary (26, 27) state. The mobile impeller (generator or pump with 1 or 2 input or output guiding devices or input and output (26, 27) or not) can have the generator functions (Fig. 11-12) , pump / compressor, hydrodynamic sealing of bandage in the form of a turbine / (Fig. 3), transformer of the reciprocating movement of fluid in rotary movement of the shaft (Fig. 1 or 11-12) and automatic gearbox (Fig. 11-12).

It comes from the definition of the present channel turbines that the generalizing proportion [vector proportion] for the complete turbine is [r ₃ ; d ₃ ; Q ₃ ; N ₃ ; β ₃ ; 8 ₃ ; l ₃ ]: [r ₁ ; d ₁ ; Q ₁ ; N ₁ ; β ₁ ; a ₁ ; l ₁ ]:

[r _M ; d _M ; Q _M ; N _M ; -; -; -]: [r ₂ ; d ₂ ; Q ₂ ; N ₂ ; β ₂ ; a ₂ ; l ₂ ]: [r ₄ ; d ₄ ; Q ₄ ; N ₄ , B ₄ ; a ₄ ; l ₄ ] can have any value (where r _i ≥0, d _i > 0, Q _i > 0, N _i > 0, 0 ° ≤ B _i ≤180 °, 0 ° ≤ a _i ≤ 180 °), in particular , N _M <min [N ₁ ; N ₂ ], d _M <min [d ₁ ; d ₂ ]; l _i ≥ 0.

The cross sections of the channels (7) and the nozzles (11) can have any shape, in particular a very narrow slot shape (34 - Fig. 6).

The output of a generator working wheel can be equipped with a momentary centrifugal regulator

(Fig. 8-9). It is composed of the outlet nozzles (11 ₂ ) installed on a shoe (21) changing the working radius r ₂ inversely proportional to the angular speed w of the turbine. The axis (16) of the turbine is located between the nozzle (2) and the center (22) of gravity of the shoe (with the nozzle); the spring (23) tightens the shoe in the direction of the nozzle (2).

The turbine can be used in sets of turbines with the functions of recuperator, transmission with two shafts and also of transformer of the reciprocating movement of the medium into rotary movement of the shaft.

The transformer of the reciprocating movement of the medium in rotary movement of the shaft consists of two generator turbines [in full] of the same direction of rotation; the inlet of the first completed turbine agrees with the outlet of the second by stationary cavity / pipe connection / stationary (27) of variable volume and the outlet of the second turbine agrees analogously with the inlet of the first . The exchange of liquid between these 2 cavities takes place by means of pistons (32) without valves.
