FIELD: machine building.SUBSTANCE: invention is related to hydraulic machine building in terms of renewable power sources. A hydraulic pulser comprises a feed line 1, a guide vane 2 with blades 3 forming centripetal drain channels, blades set above the said channels and forming centripetal pressure channels 6, and an impeller 8 with blades 10 forming drain and pressure centripetal channels 11 and 14 of a hydroturbine stage of the impeller is mounted on a shaft 22, the channels 11 lead out to the diffuser of a draft tube 26 with the radial blades of centrifugal pressure pump impeller stage being set above the channels 14. Electromagnets are set in the blades of the guide vane 2. The electromagnet windings are connected to a current source via a current reverse switch 32, the current source is installed on a common shaft 22 with a low-speed generator 31. The generator 31 contains a rotor position sensor. Permanent magnets 16 are installed in the cavities forming channels 11 and 14 of the impeller 8.EFFECT: invention is aimed at the provision of improved output parameters and possibility to change the supply and head of fluid at the hydraulic pulser output.2 cl, 7 dwg |
