Abstract

La invención se refiere a una bomba corriente libre, cuyo rodete (2), que está constituido por un disco de soporte (6) equipado con paletas (7; 8) abiertas, mantiene con respecto a la pared (12) de la carcasa opuesta al mismo en el lado de aspiración una distancia tal que desde la entrada (11) de la bomba de corriente libre hasta la salida del rodete entre el rodete (2) y la pared (12) de la carcasa se mantiene un pasillo que permite el paso libre de un objeto esférico de tamano determinado que está contenido en el líquido de transporte. Para crear una bomba de corriente libre que consigue un alto rendimiento cumpliendo el requerimiento de un paso libre para una bola de tamano predeterminado, la invención prevé que el pasillo que permite el paso libre del objeto esférico se extienda con una extensión mínima (M), que corresponde al paso esférico deseado, desde la entrada (11) hasta la salida del rodete a través del sistema de paletas del rodete (2).The invention relates to a free running pump, whose impeller (2), which is constituted by a support disk (6) equipped with open vanes (7; 8), keeps with respect to the wall (12) of the opposite housing on the suction side there is a distance such that from the inlet (11) of the free current pump to the outlet of the impeller between the impeller (2) and the wall (12) of the housing a corridor is maintained allowing the free passage of a spherical object of determined size that is contained in the transport liquid. In order to create a free current pump that achieves high performance by fulfilling the requirement of a free passage for a predetermined ball size, the invention provides that the passage allowing the free passage of the spherical object is extended with a minimum extension (M), corresponding to the desired spherical passage, from the inlet (11) to the outlet of the impeller through the impeller vane system (2).
