The invention relates to the field of engineering, namely, hydraulic machines working in turbine mode.

A known hydraulic machines, comprising a housing with inlet and outlet nozzles and inside it fixed and movable disks facing each other, the surfaces of which are made of alternating recesses and protrusions, forming a working channel.

The disadvantage of this hydraulic machine is that it has no reversibility, i.e.,. the villas improve the effectiveness of the labyrinth-vortex fluid machines at its work in the turbine mode due to the formation of radial vortex spin centripetal flow in the working channels. The working body, rotating in the cavity of the working channel, the cross-sectional area which increases from the periphery to the center, provides the transfer of energy in the labyrinth-the vortex chamber formed by the channels of the movable and fixed disks. Converts the kinetic energy of the swirling flow into mechanical energy of rotation of the shaft of the hydraulic machine.

The technical result, which can be obtained by carrying out the invention, consists in extending the functionality of the labyrinth of machines, as it promotes the efficient use in the economy labyrinth-vortex fluid machines as turboupload.

This technical result is achieved due to the fact that in the labyrinth-the vortex of hydraulic machines, comprising a housing with inlet and outlet nozzles and inside it fixed and fixed on the shaft of the movable disks facing each other, the surfaces of which are made of alternating recesses and projections forming the working channels, the surface of alternating grooves and ridges forming the working channels of the labyrinth-the vortex chamber in each section, perpendicular to the radius, limited arcs of circles, their channels. Inlet connection is located on the periphery and is made tangential and the outlet is located centrally and executed axial. In addition, between the body and the inlet manifold can be installed nozzles, the width of which is equal to the width of the peripheral part of the labyrinth-the vortex chamber, and its axis is placed in the ring plane, rejected in the side of the plane of the rolling disk. The machine can be equipped with additional nozzles spaced around the circumference of the peripheral part of the labyrinth-the vortex chamber. The flow part nasdaw may be communicated with the inlet manifold through the manifold, and the outlet diffuser made.

A causal relationship between the set of essential features of the invention and achieve the result is that the working fluid or gas flow coming from the tangential inlet pipe located in the peripheral part of the labyrinth-the vortex chamber through the discharge device contributes to the formation of its working channels radial vortex column, since the velocity vectors in the working channels as movable and fixed disks are circumferential and radial components of velocity.

R the working cavity of the labyrinth-the vortex chamber by changing the cross-section area of the working channels, formed by projections and depressions on the movable and fixed disks. Increase capacity hydraulic machines working in the turbine mode, can be carried out through the use of several tangential inlet devices forming the discharge device nasdaw spaced around the circumference and having individual or shared by a ring collector supply active working fluid or gas. The working body, rotating in the cavity of the working channel, the cross-sectional area which increases from the periphery to the center, provides the transfer of energy in the labyrinth-the vortex chamber formed by the channels of the movable and fixed disks. Thus the kinetic energy of rotation of the impeller by means of projections on the movable disc is transmitted to the shaft of the hydraulic machine. Converts the kinetic energy of the swirling flow into mechanical energy of rotation of the shaft. To maintain energy a part of the working fluid (liquid or gas) is removed from the channels of the labyrinth-the vortex chamber through the axial exhaust pipe.

The increase in the area bore of operating channels from the periphery to the center corresponds to a change of volume expansion is when using liquid as a working body diffusionist working channels promotes uniform removal of energy in each radial section along the length of the labyrinth-the vortex chamber, as with the approach to the center of the rotating speed of the flow decreases, and the contact surface of the fluid and the rotating disk increases. The use of labyrinth-vortex hydraulic machines working in the turbine mode, extends the functionality of the labyrinth of machines, as it promotes the use of it as a turbo drive in separate areas of the economy.

In Fig. 1 presents schematically a labyrinth-vortex machine, longitudinal section; Fig. 2 section a-a in Fig. 1, representing its transverse section, and Fig. 3 section b-b In Fig. 1, showing the operating channels of the labyrinth-the vortex chamber.

Labyrinth-vortex hydraulic machines includes a housing 1, 2 fixed and movable 3 discs on the sides of which are formed recesses 4 with the tabs 5, forming radial operating channels at the tangential inlet pipe 6 and an axial diffuser exhaust pipe 7. The discharge device is provided with a nozzle 8. In addition, the hydraulic machines has a shaft 9, on which you have installed the disc 3, and may also be provided for receiving the reservoir, the cavity of which communicates with the nozzles 8 and the exhaust pipe 6.

Labyrinth-vortex hydraulic machines operates as about what edstam inlet pipe 6 through a pressure device in the form of a nozzle 8. In the working channels formed by the grooves 4 on 2 fixed and movable 3 disks, is formed radially of the vortex column of swirling flow. Thus the kinetic energy of rotation of the working fluid by means of projections on the movable disc 3 is transmitted to the shaft 9 of the hydraulic machines. Converts the kinetic energy of the swirling flow into mechanical energy of rotation of the shaft.

To maintain energy a part of the working fluid is removed from the channels of the labyrinth-the vortex chamber through the axial discharge port 7. The increase in the area bore of operating channels from the periphery to the center corresponds to the change in volume of the gas expansion, providing the maximum degree of expansion and increased efficiency of energy conversion. When using the liquid as a working body diffusionist working channels promotes uniform removal of energy in each radial section along the length of the labyrinth-the vortex chamber so as to approach the center of the rotating speed of the flow decreases, and the contact surface of the fluid and the rotating disk 3 increases.

Increase capacity hydraulic machines working in the turbine mode, can be osunix nasdaw 8, having a common annular collector battery active working fluid. Install the nozzle 8 at an angle to the plane of the rolling disk 3 contributes to the formation of spin flow at the entrance to the working channel, increasing the degree of swirl flow. The use of diffuser vent 7 increases the removal of useful power from the shaft 9 hydraulic machines, as it increases the pressure drop in the working channels.

The use of labyrinth-vortex hydraulic machines working in the turbine mode, extends the functionality of the labyrinth machines when they are used in the national economy.
