FIELD: power engineering; mechanical engineering.
SUBSTANCE: invention can be used in liquid-handling pumping facilities. According to invention, in proposed axial-centrifugal motor-pump, stator of electric motor is hermetically isolated from passage part of motor-pump by diaphragm made of dielectric material. Magnetic circuit of rotor is laminated, made of electric sheet steel with short-circuited aluminum winding and is press-fitted into bladed impeller made of light aluminum alloy. Impeller-rotor is installed on axle secured in housing for free rotation.
EFFECT: provision of protection of stator winding of electric motor of motor-pump from harmful mechanical and chemical action of handled liquid, reduced heating of handled liquid and motor-pump as a whole, increased power characteristics, reduced energy losses, increased efficiency and improved mass and size characteristics of pumping unit.
