Abstract

Bomba de drenaje que comprende una bomba de paletas rotatorias (50) conectada al eje de transmisión de un motor y una carcasa para contener dicha bomba de paletas rotatorias, comprendiendo dicha bomba de paletas rotatorias una parte de eje (420) conectada a dicho eje de transmisión del motor, una pluralidad de paletas de gran radio (450) montadas sobre dicha parte de eje (420) en dirección radial, una pluralidad de paletas de pequeño radio (410) montadas debajo de dichas paletas de gran radio (450) en dirección axial, un elemento anular en forma de disco (460) que presenta una parte hueca (462) conectado a las partes de borde inferior de dichas paletas de gran radio (450), y un elemento mural cilíndrico (470) montado en la parte de borde externo de dicho elemento anular en forma de disco para conectar las partes de borde periférico externo de dichas paletas de gran radio, caracterizada porque la relación entre la altura (S) de dicho elemento mural cilíndrico (470) y la altura (T) de dichas paletas de gran radio (450) se establece en un valor del rango comprendido entre el 66% y el 83%, y porque las partes de borde superior (451) de dichas paletas de gran radio (450) sobresalen axialmente, quedando expuestas, de la parte de borde superior (472) de dicho elemento mural cilíndrico (470) una distancia que es radialmente constante.
