Abstract

Настоящее изобретение относится к системе аэрации воды для гидравлических турбин, которая может быть встроена в конусы отсасывающей трубы гидравлической турбины для увеличения содержания растворенного кислорода в воде, выпускаемой из гидроэлектростанций. Система аэрации воды для гидравлических турбин согласно настоящему изобретению представляет собой систему, содержащую устройство аэрации воды, которое осуществляет аэрацию посредством перфорированных пластин, которые вместе с опорной решеткой дублируют внутреннюю геометрию первоначального конуса отсасывающей трубы турбины, посредством отверстий, калиброванных относительно доли пустот, необходимой для аэрации потока в турбине. Впрыск воздуха в турбину основан на уровне давления в турбине и недостаточном значении содержания растворенного кислорода в воде, показания которых задействуют модуль управления процессом аэрации, что сводит к минимуму потребление энергии, необходимой для аэрации, за счет активации естественной аэрации без соответствующего потребления энергии или принудительной аэрации, осуществляемой с подачей сжатого воздуха.
