Title
(EN) DEVICE AND METHOD FOR SUCTION PIPE
(FR) DISPOSITIF ET PROCEDE POUR TUYAU D'ASPIRATION
Abstract
(EN)
A method and device for reducing noise and vibrations in a suction pipe (1) in a reaction-type hydropower turbine. The suction pipe (1) comprises one or more nozzles (2) for injection of a working medium through the nozzles (2) into the suction pipe (1). Each nozzle is arranged at an angle ϝ relative to a horizontal plane perpendicular to the longitudinal axis (4) of an inlet (3) of the suction pipe (1) and at an angle &bgr; relative to a horizontally defined tangent (6) at the point of intersection between each nozzle (2) and the suction pipe (1).
(FR)
La présente invention concerne un procédé et un dispositif permettant de réduire le bruit et les vibrations dans un tuyau d'aspiration (1) d'une turbine pour énergie hydroélectrique du type à réaction. Le tuyau d'aspiration (1) comporte une ou plusieurs tuyères (2) pour l'injection d'un milieu de travail par lesdites tuyères (2) vers l'intérieur du tuyau d'aspiration (1). Chaque tuyère est disposée pour former un angle $g(g) par rapport à un plan horizontal perpendiculaire à l'axe longitudinal (4) d'une entrée (3) du tuyau d'aspiration (1) et un angle $g(b) par rapport à une tangente définie horizontalement (6) au niveau du point d'intersection entre chaque tuyère (2) et le tuyau d'aspiration (1).
