FIELD: agriculture; pumps. ^ SUBSTANCE: invention can be used for water supply in agriculture using open flows. Design peculiarity of proposed water pump is replacement of mechanical connection provided by articulated tie-rods, overrunning clutches and accumulating spring by hydraulic coupling with use of drive vessel and spool-and-spring drive. Thanks to it simultaneous and quick (instantaneous) opening (closing) of intake and outlet channels is provided. Pump is ecologically clean device capable of operating at head of 0.5 m and higher owing to use of open flows (streams, rivers, etc) to supply water for people, animals, watering irrigation of fields and fire fighting. ^ EFFECT: enlarged operating capability and reliability. ^ 3 dwg |
