Abstract
Изобретение относится к лопастному колесу насоса центробежного или полуосевого типа, предназначенного для откачивания жидкостей, главным образом сточной воды. Согласно изобретению рабочее колесо насоса содержит ступицу (1), снабженную одним или несколькими лопастями (2), рабочие кромки (3) которых сильно изогнуты назад. Величина угла изгиба изменяется в интервале 35-65° в месте соединения со ступицей и в интервале 55-85° на периферии.
