FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used ion designing of hydraulic machines for delivery of liquids to consumers, in form of hydraulic motor, hydraulic propulsor and also as turbine and active emulgator. Proposed rotary hydraulic machine has housing with axial inlet and peripheral outlet branch pipes and rotor in form of solid of revolution with hydraulic channels in form of multistart screw spirals installed on shaft. Rotor is made in form of hemisphere or truncated cone and it contains intake chamber in narrow part of rotor from which hydraulic channels are laid inside rotor volume. Outputs of hydraulic channels are located on periphery in wide part of rotor or on its end face. Hydraulic channels are made with pitch from 0.5 to 1.0 of rotor height along its axis, and intake chamber in made on form of truncated cone. ^ EFFECT: enlarged sphere of application, reduced losses, provision of operation without cavitation. ^ 2 cl, 1 dwg |
