Abstract

Conformación de los rodetes para rotores de bombas centrifugas, de tipo radial y semiaxial, caracterizada porque el comienzo del rodete en el lado de aspiración se ha ejecutado como recta o línea muy poco curvada (2) bajo un ángulo (Bs) de 0 a 5 grados frente a la dirección periférica encontrándose la longitud (1) de la recta o de la línea (2) muy poco curvada entre un valor mínimo de 3 mm. y un valor máximo igual a la longitud de la graduación del rodete (t).
