Abstract

The invention relates to the pump engineering, in particular to the rotors of the centrifugal pumps.The rotor, according to the invention, consists of two shrouds: drive and driven, joined between them by blades, installed with the angles of inlet β1 and outlet β2 from the rotor. The number of blades Z is determined from the relation:where D1 - the inlet diameter of the rotor; δ- the blade thickness at the inlet into the rotor.The angles β1 and β2 are selected within the limits of 16…24° and 22…35°, accordingly, being provided the dependence L·Z ≥ 2πD1, where L is the length of the blade chord.The result of the invention consists in decreasing the mass and dimensions and in increasing the efficiency of the centrifugal pump.
