FIELD: dewatering of reservoirs and depressions to be empties.
SUBSTANCE: proposed water lifting device contains lifting, suction and air delivering pipes and mixing chamber with inclined nozzle holes uniformly spaced over circumference of inner cup of mixing chamber. Axes of holes are generative of one-nappe hyperboloid of rotation. Suction branch pipe is furnished with hood head made in form of truncated cone with larger base pointed downwards and attachment of smaller base to end face of suction branch pipe. Vertical trapezoidal plates are installed on inner surface of hood head tangentially to cylindrical part of suction branch pipe in direction of circular inclination of axes of mixing chamber nozzle holes. Smaller bases of trapezia are arranged over outer perimeter of head.
EFFECT: enlarged sphere of application.
