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 ?1 and outlet ?2 from the rotor. The number of blades Z is determined from the relation:<CHFORM>where D1 - the inlet diameter of the rotor; ? - the blade thickness at the inlet into the rotor.The angles ?1 and ?2 are selected within the limits of 16...24 degree and 22...35 degree , accordingly, being provided the dependence L.Z???D1, 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.Claims: 3Fig.: 4
