Suction pipe and method for reducing noise and vibrations in a suction pipe |
摘要 |
<p>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 γ 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).</p> |
