Abstract

La invención se refiere a una bomba centrifuga que tiene una entrada axial y un dispositivo de guía del flujo de entrada montado aguas arriba del impulsor, que el dispositivo de guía está compuesto por varias ruedas de paletas rígidas de guía, las cuales en el lateral mirando hacia el impulsor tienen un borde dirigido hacia o alejándose de la dirección de rotación del impulsor. Dicho borde dirigido hacia o alejándose de la dirección de rotación está contenido por una plancha torcida (8) colocada en el área de la pared de la entrada (2), que se perfila contra la rueda de palas de guía (6) y es más corta radialmente que la rueda de palas de guía (6). Esto aumenta la efectividad de la bomba y consigue un efecto que incrementa la accesibilidad a la turbomáquina.
