Patent FR2123831A5

Hydraulic turbine blade control assembly - applies opposite blade rotation forces by rotary gate ring and servo motors to reduce vibrations (BR310876)

A hydraulic turbine blade control assembly has one(7) of each pair of blade pivot shafts (7, 8) connected by a lever and link with a gate ring(2), the rotation of which is controlled by the servo- motors (4) and (5) with supply pipes (9) and return pipes (10). Each lower shaft (8) is actuated by the servo-motor (3) with supply pipes (11) and return pipes (12). The resultant couple on each blade (1) is the difference between the couples applied by the two sets of servo-motors. Because there is a force acting on both shafts (7), (8) play in the pivots is eliminated with a consequent reduction in blade vibration. Shear pins (6) prevents any overload being transmitted to the blades.

Hydraulic machine inlet guide vane pitch changer - has Belleville washers acting on pivoted levers to hold rollers in tracks of boss

The pitch of the inlet guide vanes of a hydraulic pump or turbine is changed by rotation of the lever (2). The boss (3) of the lever (2) is provided with a central opening so shaped that an indentation (7) is formed between the surface (15, 17). Two levers (10) are mounted on pivots (12) on the vane shaft (1). The levers (10) carry rollers (6) which normally lie in the indentations (7) being held there by the force of the stack of Belleville washers (9). If the vane becomes jammed the spring force is overcome and the rotation of the lever (2) is not transmitted to the vane shaft (1) since the rollers (7) run over the track (16).

Electro hydraulic servo control of turbine nozzle box - has solenoid operated clamp on control rod for momentary limitation of opening

Mechanism controls the opening of a turbine high pressure nozzle box via a load-sensitive electrical controller controlling an auxiliary valve which allows hydraulic fluid to flow from a constant pressure source to a distributor valve which feeds the servo actuating the cam control for the nozzle box whilst a mechanical relay with operating arm and valve limits the nozzle box opening by modulating the outflow of fluid from the distribution valve. Means for momentary direct limitation of the opening, consist of a clamp arranged in the centre of the valve into which clamp a rod of the arm extends. The clamp can be actuated to grip the rod by means of a slenoid valve, to obtain direct actuation by the valve of the mechanical relay.

Device for controlling the movement of a hydraulic cylinder, particularly for hydraulic machines.

La invención se refiere a un dispositivo de control (16) que incluye una válvula (26) que incluye un cuerpo (30) conectada a la primera cámara (22) de un cilindro (6) a través de una primera conexión hidráulica (32) y a la segunda cámara (24) del cilindro (6) a través de una segunda conexión hidráulica (34). El dispositivo incluye un primer conducto hidráulico (42) para ser conectado a una primer fuente de fluido de accionamiento (40), y un segundo conducto hidráulico (46) para ser conectado a una segunda fuente de fluido de accionamiento (44), dichos conductos hidráulicos (42, 46) en comunicación con el cuerpo (30) de la válvula (26), dicha válvula (26) incluye además un dispositivo de distribución (56) que es móvil dentro del cuerpo (30) de la válvula (26), entre una primera posición, en la que el dispositivo de distribución (56) coloca la primera conexión hidráulica (32) y el primer conducto hidráulico (42) en comunicación de fluido, y una segunda posición en la que el dispositivo de distribución (56) coloca la segunda conexión hidráulica (34) y el segundo conducto hidráulico (46) en comunicación de fluido.

METHOD FOR REHABILITATION OF ENERGY CONVERSION INSTALLATION AND REHABILITATED ENERGY CONVERSION PLANT

Ce procédé permet de réhabiliter une installation de conversion d'énergie hydraulique en énergie électrique ou mécanique, et réciproquement, comprenant une turbine-pompe de type Francis. La turbine-pompe comporte une roue mobile autour d'un axe, un avant-distributeur (204), comprenant des avant-directrices définissant entre chaque paire de deux avant-directrices adjacentes un premier canal (C1) de passage de l'eau et un distributeur (206'), comprenant des directrices disposées en aval des avant-directrices dans le sens d'écoulement d'eau alimentant la turbine-pompe fonctionnant en mode turbine, les directrices définissant entre chaque paire de deux directrices adjacentes un deuxième canal (C2) de passage de l'eau. Ce procédé comprend des étapes consistant à réduire la hauteur, prise parallèlement à l'axe de rotation de la roue, des premiers canaux (C1) de passage de l'eau et à réduire la hauteur, prise parallèlement à l'axe de rotation de la roue, des deuxièmes canaux (C2) de passage de l'eau. This method makes it possible to rehabilitate a hydraulic energy conversion installation into electrical or mechanical energy, and vice versa, comprising a Francis-type turbine-pump. The turbine-pump comprises a wheel that is movable about an axis, a forward distributor (204), comprising front-guides defining between each pair of two adjacent front-guides a first channel (C1) for the passage of water and a distributor (206 '), comprising guides arranged downstream of the front-guiding in the direction of flow of water supplying the turbine-pump operating in turbine mode, the guides defining between each pair of two adjacent ducts a second channel ( C2) of water passage. This method comprises steps of reducing the height, taken parallel to the axis of rotation of the wheel, of the first channels (C1) for the passage of water and reducing the height, taken parallel to the axis of rotation of the water. the wheel, second channels ( ...

Thrust adjusting mechanism for hydraulic turbine wicket gates

Means are provided for limiting the axial thrust of the turbine wicket gates. A plate adjustably connected to the turbine headcover is selectively positioned relative to a shoulder on the wicket gate shaft to provide the proper thrust clearance.
