Abstract
Изобретение относитс к гидротехнике и может быть использовано в гидроэлектростанци х дл подвода воды к гидротурбинам. Цель изобретени - повышение надежности работы гидротурбины путем предотвращени попадани наносов в турбинный тракт. Напорный водовод малой ГЭС включает трубу 1, нижний участок которой выполнен в виде спирали 2. В наружней стенке спирали 2 имеетс продольна щель 3, котора закрываетс отводом 4, а последний с помощью трубопровода 5 сообщаетс с нижним бьефом. При движении жидкости по спирали 2 твердые частицы наносов под действием центробежной силы прижимаютс к внешней стенке спирали 2 и через щель 3 попадают в отвод 4 и по трубопроводу 5 перемещаютс в нижний бьеф, мину рабочее колесо гидротурбины. Таким образом, обеспечиваетс увеличение межремонтного периода работы гидротурбины. 3 ил.The invention relates to hydraulic engineering and can be used in hydroelectric power plants for supplying water to hydro turbines. The purpose of the invention is to improve the reliability of the turbine by preventing sediment from entering the turbine path. The pressure conduit of a small hydroelectric station includes a pipe 1, the lower part of which is designed as a helix 2. In the outer wall of helix 2 there is a longitudinal slit 3, which is closed by a branch 4, and the latter is connected with the downstream pipe 5 by means of pipeline 5. When the fluid moves in a spiral 2, the solid particles of sediment are pressed to the outer wall of the spiral 2 under the action of centrifugal force, and through the slit 3 fall into the outlet 4 and through the pipeline 5 they move to the lower reach of the turbine impeller. Thus, an increase in the turnaround time of the turbine is provided. 3 il.
