Abstract
Центробежный насос, содержащий корпус, внутри которого на валу размещено центробежное колесо с уплотнениями и каналами перепуска утечек во входную зону центробежного колеса и дисковый обтекатель с лопаточной решеткой со стороны каналов перепуска утечек, отличающийся тем, что в нем, в дисковом обтекателе, со стороны каналов перепуска выполнена приемная кольцевая полость, профиль которой напротив каналов перепуска плавно изогнут в направлении входа в межлопаточные каналы лопаточной решетки, при этом радиус расположения каналов перепуска выполнен меньше радиуса входных кромок лопаточной решетки дискового обтекателя.A centrifugal pump comprising a housing, inside of which a centrifugal wheel with seals and leakage bypass channels to the inlet zone of the centrifugal wheel and a disk cowl with a spatula grill on the side of the leakage bypass channels, characterized in that in it, in the disk cowl, on the side of the channels the bypass has a receiving annular cavity, the profile of which opposite the bypass channels is smoothly curved in the direction of entry into the interscapular channels of the scapular lattice, while the radius of the bypass channels and made smaller than the radius of the input edges of the blade grating disk fairing.
