Abstract

Dispositivo di spurgo dell'aria per pompa centrifuga sommergibile, che permette l'innalzamento del liquido nel corpo di pompa prima della messa in marcia.Esso comprende una cavità (2) a doppia parete (3, 4) nell'involucro della pompa, e due orefici (5, 6) che comunicano con l'interno e l'esterno della pompa. Tra le due pareti della cavità (2) è disposta una membrana flessibile e piana a riposo, che si curva quando la pompa è in marcia per chiudere l'orificio (6) ed impedire la fuoriuscita di acqua da questo orificio.L'invenzione è utilizzata principalmente per il comando automatico di una pompa sommergibile aspirante l'acqua su un suolo piatto.Air purge device for submersible centrifugal pump, which allows the liquid to rise in the pump body before starting. It includes a double-walled cavity (2) (3, 4) in the pump casing, and two goldsmiths (5, 6) that communicate with the inside and outside of the pump. Between the two walls of the cavity (2) there is a flexible and flat membrane at rest, which curves when the pump is running to close the orifice (6) and prevent the escape of water from this orifice. mainly used for the automatic control of a submersible pump suction the water on a flat ground.
