The present invention relates to the field of hydro in the part of renewable energy sources and can find application in systems and installations for water supply, irrigation, drying, increase the pressure on the micro - and minges, water accumulation in marine gateways, and so on

In the present invention, improved known design geroulanos containing a supply, a guiding apparatus, a turbine impeller, a discharge outlet, a discharge pipe, as well as radial and axial support for the shaft of the impeller (see, for example, F. C. konradi "Hydropulse Tashkent 1939, and hydropulse by author's certificates and patents of the USSR class 59 C., 17 №24710, №65722, №18057, №79816 and devices using electro Yutkin effect, and.with. №62683, №72308,№73453, №792003, №1733710 And, RF patent №2157893, No. 2207230 and others).

Also known construction hydropulse containing a supply, the guide device with the blades forming the centripetal drainage channels placed over these channels blades, forming a centripetal pressure channels, and mounted on the shaft of the impeller with blades forming drain and pressure centripetal channels turbine speed of the wheel, and the output of the drain channels are in the cone draft tube, and placed over the discharge channels R is dialname blades centrifugal pressure pump stage wheel (see patent for invention No. 2457367 06.07.2010,).

This design hydropulse can be adopted for the base object.

The design flaws of the specified base object are:

1) Unattainability or uncertainty desired output parameters hydropulse (feed pressure and flow rate), especially when limited to low-altitude backwater of the water column at the entrance to hydropulse, because you may not have enough power two centripetal turbine-speed radial-flow impeller to ensure reliable operation of its centrifugal pump stage and a pulse of fluid to the wheel.

2) the Inability to change the output parameters in the same design forms and sizes hydropulse.

The task, which is aimed by the invention, provides for eliminating these disadvantages, i.e., providing increased output parameters, and possible changes in the flow and pressure of fluid at the outlet of hydropulse.

The solution of the problem is due to the fact that hydropulse containing a supply, the guide device with the blades forming the centripetal drains placed over these channels blades, forming a centripetal pressure channels and mounted on the shaft of the impeller with the main and additional blades, forming drain and pressure centripetal channels turbine speed of the wheel, and the output of the drain channels are in the cone draft tube, and placed over the discharge channels of the radial blades of the centrifugal pressure head of the pump stage wheels:

- besides, at the level of the guide vanes forming a centripetal pressure channels, spiral or circle made system of isolated electrodes with positive tension electrohydraulic discharge-pulse devices that are connected to the rotary switch with low-speed high-voltage generator, and both are mounted on a common shaft hydropulse and negative electrodes in the form of a metallic blade-edges made in a centripetal pressure channels of the impeller and connected to ground;

in the guide vanes forming a centripetal pressure channels, the system isolated electrodes with positive tension electrohydraulic discharge-pulse devices that are connected through the same switch with the same generator, and main blades, forming a centripetal pressure channels of the impeller, made more similar channels, which also installed tricatel the data electrodes in the form of a metallic blade-edges, connected to the ground.

The specified device design electrohydraulic except hydromechanical effects on its impeller uses electrohydraulic effect Yutkin) - a method of directly converting electrical energy into mechanical energy with high efficiency through the implementation within the volume of fluid specially formed high-voltage pulse electric discharges in a short time, around areas of education are experiencing a high hydraulic pressure, able to perform useful mechanical work. Microscopic channel, which forms a spark discharge, has a very high energy density with the possibility of an allocation in a given direction. Instantly allocated capacity reaches huge values, with water surrounding the spark, once in the zone of strong buoyancy action quickly spread to the sides, creating a zone of compression of the first hydraulic shock. Vacuum - cavity, which immediately filled with water, the result is another powerful hydraulic shock - cavitation. High hydraulic pressure as the distance from the discharge decrease rapidly (approximately proportional to the square of the distance from it). Thus, the electrical energy generated by electrohydraulic bit is the bottom width high pulse of hydraulic pressure, provide high-voltage electrical pulses with steep leading edge of the voltage applied to the bit period in the liquid, without any intermediate links is transferred into mechanical energy. In the specified device is relatively slow charge member capacitor from the power source of high voltage (e.g., switched reluctance low-speed generator), and then when the circuit closing bit of the elements of the device, there is a rapid discharge of the capacitors to discharge between electrodes in the liquid (the less the duration of the pulse front, the more impulsive current and pulse peak power). The breakdown voltage on the gap between the electrodes in the liquid depends on the liquid properties, shape and design of the electrodes and the polarity of the voltage on the electrode with the higher tension. For technical water when using sharp electrode positive polarity and increased active surface of the negative electrode breakdown strength is about 1 kV/cm2.

Converted from electrical to mechanical energy hydraulic shock pushes fluid through a centripetal pressure channels of the impeller, thus increasing torque on agropostach and hydraulic pulse in the moving fluid, consequently, increasing the pressure and flow of electrohydraulic.

Change the output settings in electrohydraulic can be done by changing the parameters of their constituent structural elements and the change of the amplitude of the current pulse duration and steepness of the front of the pulse and the voltage of the discharge.

To increase the breakdown tension (pulse energy), front steepness of the current pulse and the length of the sparks applied circuit using multiple capacitors connected in parallel to the charge-voltage current source, and then switching the switching device on the serial connection. The output voltage at the load increases in proportion to the number of connected capacitors.

The increase in voltage causes an increase in efficiency and increases the "stiffness" of electro-shock, and, for example, the use of increased capacity leads to its softening, making it longer. Soft mode is characterized by a lower pressure at a substantially increased proportion of energy which is lost with the wave delayed flow and the decrease in energy due to the shock wave front.

When thin bare conductor working positive electrode of a thin metal plate, matching his plane the direction of the conductor, and its end extends over the edge of the plate, due to the effect of the pulse capacitor formed by plate and a second (negative) conductor, the transformation of the steepness of the front of a long primary pulse by converting it into a short steep front of the secondary work impulse, and the discharge becomes longer.

The overall electrical efficiency of electro-hydraulic installation is increased.

In known constructions of geroulanos rotating radial-axial turbine impeller directs the flowing fluid in the drain, the pressure in the cavity due to the fact that Francis centripetal channels wheels are opened alternately up and down. When opening the channels down the liquid with the free discharge to the lower reaches some maximum speed at which the rotating impeller turning at a certain angle, closes the drain channels and opens facing upward pressure channels.

Thanks to the acquired momentum of the fluid is directed through outlet ports in the discharge line, lifting up into the liquid. Because of the work produced uplift and energy loss of pressure in the supply decreases, the water comes to rest and would flow from the pressure cavity back, if this BP is me due to the rotation of the impeller has not occurred closing the discharge channels and the opening of the drain channels.

Described processes are continuously repeated, and the liquid in the inlet system hydropulse (pipe and supply, for example, spiral) pulsates between higher and lower speeds without shock.

However, a significant positive difference between the proposed design electrohydraulic is increased upornosti supplied to the consumer of fluid flow (with the same diameters of known structures) due to the enhanced torque, attached to RK, formed by addition of the hydraulic forces on the blades centripetal turbine speed of the impeller and the converted mechanical energy from the pulse electric discharges in the channels.

In addition, to enhance the overall electrohydraulic effect in electrohydraulic, and hence increase its capacity, it is possible to install systems of electrodes of the discharge-pulse device and inlet channels centrifugal stage impeller.

Using the proposed design electrohydraulic with increased parameters of pressure and flow at the output improves reliability and increases efficiency at the same parameters of the supplied liquid and the same dimensions as in the known constructions of geroulanos.

Thus, the claimed design electrohydraulic has technical what their advantages in comparison with known designs geroulanos.

Data supporting the validity of achievements solve this problem the invention described in technical literature (see, for example, Lorenz and E. Prager "Taran and hydropulse", B. N.

When electrohydraulic liquid of the upstream (intake) pools under pressure is fed through a pipe to supply 1, which falls into the guide device 2 and passes between the blades 3 in the drain channels 4 and between the blades 5 into the discharge channel 6.

From the drain channels 4 stationary guide vanes 2, the fluid acts on the blades 10 and 12 of the turbine speed of the impeller 8, causing it to rotate, then passes through its drain channels 11 in the suction pipe 26.
