Abstract

Настоящее изобретение относится к крыльчатке (12) центробежного или полуосевого типа, используемой в насосе для насосной подачи жидкостей и выполненной с одной или несколькими лопастями (18) таким образом, что лопасти прикреплены к закрывающим дискам (12, 16) на каждой стороне, образуя так называемую закрытую крыльчатку, характеризующейся тем, что передние края (40) лопастей изогнуты назад во входное отверстие (42) одного из закрывающих дисков (12) крыльчатки.The present invention relates to an impeller (12) of a centrifugal or semi-axial type, used in a pump for pumping liquids and made with one or more blades (18) so that the blades are attached to the closing disks (12, 16) on each side, forming called a closed impeller, characterized in that the front edges (40) of the blades are curved back into the inlet (42) of one of the closing disks (12) of the impeller.
