Abstract

BOMBA CENTRIFUGA DE DIFUSOR DESMONTABLE. LA BOMBA ESTA CONSTITUIDA POR UNA VOLUTA INTERCALADA EN EL CIRCUITO, UN ORIFICIO POR EL QUE SE INTRODUCE UN CONDUCTO DE ASPIRACION, UN ROTOR Y UN DIFUSOR DE FORMA ANULAR. LA CONSTRUCCION DEL DIFUSOR DESMONTABLE PERMITE UN TAMAÑO MENOR DEL ORIFICIO DE LA VOLUTA. EL DIFUSOR (21) SE COMPONE DE VARIAS PIEZAS DISPONIENDO CADA UNA EN SU PARTE SUPERIOR DE UNA GARGANTA TRAPEZOIDAL (36) QUE FORMAN, UNA VEZ ACOPLADAS, UNA GARGANTA ANULAR, Y SIMILARMENTE UN SALIENTE (37) PARA FORMAR UN ANILLO. LAS PIEZAS (21) SE INTRODUCEN POR EL HUECO (25) DE LA VOLUTA (23) Y SE PRESENTAN POR SUS SALIENTES (37) EN UN ALOJAMIENTO (38) DE LA VOLUTA.
