Abstract

Изобретение относится к прудовому насосу с крыльчаткой (2), вращающейся вокруг оси вращения (X) в корпусе насоса (1). Корпус насоса (1) имеет всасывающее входное отверстие (11), расположенное аксиально к крыльчатке (2), выходное напорное отверстие (14), расположенное в направлении от радиального до тангенциального по отношению к крыльчатке (2) и служащее для вывода воды, а также противоточную пластину (12) между всасывающим входным отверстием (11) и выходным напорным отверстием (14). Крыльчатка (2) имеет радиально расположенную циркулярную пластину (22) с расположенными на одной ее стороне лопастям (21). Противоточная пластина (12) расположена с открытой стороны крыльчатки (2) и охватывает лопасти (21). Между лопастями (21) образованы проточные каналы (23), которые имеют поперечное сечение, уменьшающееся в направлении от радиальной внутренней стороны к внешней стороне.
