Claims (1)

Погружной многоступенчатый центробежный насос, содержащий рабочие колеса со ступицами, соединенными с приводным валом с помощью шпоночного соединения в виде шпоночных канавок, и установленных в них шпонки, отличающийся тем, что шпоночная канавка на каждом рабочем колесе выполнена в виде поперечного паза с уменьшением его глубины в сторону вращения приводного вала с возможностью смещения шпонки с валом относительно рабочего колеса и фиксации их в радиальном и продольном направлениях.A submersible multistage centrifugal pump containing impellers with hubs connected to the drive shaft using a keyway in the form of keyways, and keys installed in them, characterized in that the keyway on each impeller is made in the form of a transverse groove with a decrease in its depth in the direction of rotation of the drive shaft with the possibility of shifting the dowels with the shaft relative to the impeller and fixing them in the radial and longitudinal directions.
