Turbine k. m. belova
(57) Abstract:The invention can be used as turbines small hydro. In the turbine housing 1 parallel to and opposite each other are two identical rotor 6. Plate 8 mounted in radial grooves 7 of the rotor 6. The pins 9 are made on the front ends of the plates 8. On the inner surface of the end cap 4 is made copiers grooves 5. Pins 9 interact with the grooves 5. In the upper part of the housing 1 between the rotors 6 are installed streamlined guide 11. The use of two rotors at the same time and the effects of water on the plate, starting from the top of the rotors to their bottom provides increased efficiency. 1 Il. The invention relates to hydraulic machines volumetric displacement, namely, rotary vane machines and can be used, for example, as turbine small hydro.As a prototype of the invention adopted rotary vane machine, comprising a housing with end caps, inlet and outlet nozzles located in the housing, the rotor with radial grooves in which the laminas (see patent USSR N 1056920, CL F 04 C 2/344, 1983).N is Britanie, - increase of efficiency of the turbine.The invention consists in that the turbine, comprising a housing with end caps, inlet and outlet pipes and concentric accommodated in the housing, the rotor with radial slots in which are movable plate in the housing parallel to and opposite the first set, a second similar rotor at the inner end surfaces of the covers made copiers in the form of grooves on the free surfaces of the covers made copiers in the form of grooves, on the free face end of plates made pins that interact with the grooves, and in the upper part of the body throughout its length between the rotors installed streamlined guide.The drawing shows a General view of the turbines in the section.The turbine includes a housing 1 with an inlet 2 and outlet 3 pipes and end caps 4 (in the drawing is only visible back cover). On the inner surface of the end cap 4 is made copiers grooves 5. In the housing 1 in parallel and opposite each other are two identical rotor 6 with radial grooves 7, which are plate 8, having at its end the ends of the pins 9, vzaimodeystvuesh the entire length between the rotor 6 is installed streamlined guide 11.The turbine operates as follows.The water enters through the inlet pipe 2, split rail 11 into two streams and fills the working cavity 10. The water column, the height of which is determined by the distance of honey plates and the water level in the reservoir, the pressure on the plate 8 and causes the rotating rotor 6. When this happens sequential and alternate filling and emptying of the working cavities 10. Radial movement of the plates 8 in the grooves 7 of the rotor 6 occurs under the action of the pins 9 sliding in the grooves 5.Thus, there is a continuous flow of water from the inlet pipe through the working chamber to the exhaust pipe and the rotation of the rotors. Torque from the rotors may be used, for example, to drive electric generators.Compared to conventional water wheel efficiency of the proposed turbines is increased due to the fact that water acts on the plate, starting from the top of the rotors to their bottom, i.e. almost half of the turnover of the rotor, while in the water wheel, the water acts on the rotor blades only for a quarter of a turn, and then merges on the issue. In addition, the use of two ro is Lastin provided by that water is in this case, the lubricant, and the rotational speed of the rotor is small, as this turbine is designed to work at low water pressure. Turbine, comprising a housing with end caps, inlet and outlet pipes and concentric accommodated in the housing, the rotor with radial slots in which are movable plate, characterized in that in the housing parallel to and opposite the first set, a second similar rotor on the inner surface of the end cap is made copiers in the form of grooves, on the free face end of plates made pins that interact with the grooves, and in the upper part of the body throughout its length between the rotors installed streamlined guide.
FIELD: mechanical engineering.
SUBSTANCE: invention can be used in compressors, pumps and continuous internal combustion engines. Proposed rotary-vane machine contains at least one annular cylindrical chamber, rotor with vanes eccentrically installed in chamber, vanes being fitted in longitudinal slots of rotor. Rotor divides chamber into two eccentric spaces of variable circumferential section with intake and exhaust ports. Rotor is made in form of end face plate provided with coaxial ring cylindrical projection with longitudinal cuts. Vanes are installed in cuts of projection, inserts are placed between vanes and end faces of projection cuts providing rocking and reciprocating of vanes relative to projection. End faces of vanes in contact with cylindrical walls of chamber are made with support area of surface.
EFFECT: simplified design, improved reliability, capacity and efficiency.
