Abstract

Una bomba centrífuga autoaspirante perfeccionada, dotada de al menos una célula de centrifugado (4,1,7) sometida a plena carga, con árbol horizontal (5), y de una fase de purga de aire (14,12,13) dispuesta fuera de la corriente principal de impulsión de manera solidaria en giro sobre el mismo árbol, en tipo de construcción de bomba de canal derivado o de bomba hidrorrotativa, cuya impulsión puede estar bloqueada en el régimen normal de la bomba, y cuyo lado de aspiración está comunicado, a través de un primer paso (24) abierto constantemente, con una primera zona del lado de aspiración de la célula sometida a plena carga, zona en la que se acumula el gas que ha de ser extraído por aspiración, caracterizada porque el lado de aspiración de la fase de purga de aire (12,13,14) está comunicado, a través de un segundo paso (21,23) constantemente abierto, con una segunda zona de la célula de centrifugado sometida a plena carga, zona que, durante el régimen normal, presenta una presión más alta quela primera zona, estando los dos pasos (24,21,23) dimensionados de tal modo que, durante el régimen normal, fluye a través de ellos una corriente de líquido suficiente para la refrigeración de la fase de purga de aire, desde la segunda zona de la célula de centrifugado sometida a plena carga, hasta el lado de aspiración de la fase de purga de aire, y desde allí, a la primera zona de la célula de centrifugado sometida a plena carga.
