FIELD: engines and pumps. ^ SUBSTANCE: inside parts 7, 10 of the housing, which are made in the form of tight high pressure chamber, assembly 5 of shaft transfers torque moment from electric motor 1 at least to one blade wheel 8 located in housing 7 of the pump. Between electric motor 1 and housing 7 of the pump there located is handwheel 12. All rotary parts are located inside tight motor/pump assembly which is filled with liquid. Handwheel 12 includes the housing having many cavities and inserts from heavy metal, which are located in those cavities. Inserts are made from heavy metal, the density of which is more than 11.0 kg/dm3. Housing of handwheel 12 is made from high strength material. ^ EFFECT: increasing safety and efficiency of motor/pump assembly owing to improved handwheel design, increased safety of its operation, and decreasing capacity loss on handwheel as a result of hydrodynamic friction. ^ 16 cl, 5 dwg |
