Abstract

Bomba de corriente libre para el transporte de líquidos mezclados con cantidades secundarias sólidas, con una carcasa (1), en la que está dispuesto, por una parte, un rodete (2) no cubierto en su diámetro exterior y, en la que se forma, por otra parte, un espacio abierto entre el rodete y la pared (10) de la carcasa del lado de aspiración estando asimétrico, visto en la sección mediana, el espacio de la carcasa colocado radialmente con respecto al rodete (2), y disminuyendo constantemente con el diámetro la distancia de la pared (10) de la carcasa del lado de aspiración con respecto al rodete (2), pero existiendo entre el rodete (2) y la pared (10) de la carcasa del lado de aspiración sobre toda la periferia una distancia tal que un objeto sólido contenido en el líquido de transporte, que corresponde en su dilatación máxima al diámetro de una bola predeterminada, puede pasar por la bomba de corriente libre. El cometido de conseguir la reducción del espacio de la bomba, que incrementa el rendimiento, sin tener que tolerar en este caso efectos secundarios considerables no deseados se soluciona según la invención porque la transición de la pared (10) de la carcasa del lado de aspiración hacia la pared (11) del espacio de la carcasa colocado radialmente con respecto al rodete (2) se realiza sin escalonamiento, estando asimétrico este espacio de la carcasa, visto en la sección mediana, de tal forma que las secciones transversales de las regiones colocadas radialmente con respecto al contorno de rodete (2) son mayores que las secciones transversales de las regiones colocadas delante en el lado de aspiración, y donde las secciones transversales de las regiones colocadas radialmente con respecto al contorno del rodete (2) se incrementan en dirección a la salida (12) de la bomba de corriente libre en una magnitud tal que la bola predeterminada puede pasar por la carcasa (1).Free current pump for the transport of liquids mixed with solid secondary quantities, with a housing (1), on which, on the one hand, an impeller (2) not covered in its outer diameter is arranged and, in which it is formed , on the other hand, an open space between the impeller and the wall (10) of the suction side housing being asymmetric, seen in the median section, the housing space placed radially with respect to the impeller (2), and decreasing constantly with the diameter the distance of the wall (10) of the suction side housing with respect to the impeller (2), but existing between the impeller (2) and the wall (10) of the suction side housing on all the periphery a distance such that a solid object contained in the transport liquid, which corresponds in its maximum expansion to the diameter of a predetermined ball, can pass through the free current pump. The task of achieving the reduction of the pump space, which increases the yield, without having to tolerate in this case considerable unwanted side effects is solved according to the invention because the transition of the wall (10) of the suction side housing towards the wall (11) of the space of the carcass placed radially with respect to the impeller (2) it is carried out without stepping, this space of the carcass being asymmetric, seen in the median section, such that the cross sections of the regions placed radially with respect to the impeller contour (2) are larger than the cross sections of the regions placed in front on the suction side, and where the transverse sections of the regions placed radially with respect to the impeller contour (2) are increased in direction at the outlet (12) of the free current pump in a magnitude such that the predetermined ball can pass through the housing (1).
