Abstract

Mejoras introducidas en bombas centrífugas.#Estas bombas (1) comprenden en principio una carcasa (2) con una boca de entrada (6) y otra de salida (7) de un fluido, a la vez que en su interior se aloja una turbina (3) acoplada en un apoyo posterior y otro anterior que separa este último una cámara de aspiración (13) y una cámara de impulsión (8).#Las mejoras se caracterizan porque comprenden un anillo de obturación de estanqueidad axial que proporciona un cierre estanco perimetral entre dichas cámaras (8-13), anillo que se ubica en un hueco angular (16) establecido en correspondencia con el apoyo anterior.#El anillo de obturación se acopla con un cierto apriete en una porción terminal (15) de la turbina (3), cuyo giro arrastra al anillo que realiza el cierre axial al contactar el mismo contra un tramo frontal plano (18) de un rebaje angular (14) de la carcasa (2) de la bomba (1).Improvements introduced in centrifugal pumps. # These pumps (1) in principle comprise a housing (2) with an inlet (6) and an outlet (7) of a fluid, while a turbine is housed inside (3) coupled in a rear and a previous support that separates the latter a suction chamber (13) and a discharge chamber (8). # The improvements are characterized in that they comprise an axial sealing sealing ring that provides a tight seal perimeter between said chambers (8-13), a ring that is located in an angular recess (16) established in correspondence with the previous support. # The sealing ring is coupled with a certain tightening in a terminal portion (15) of the turbine (3), whose rotation drags the ring that performs the axial closure when it contacts it against a flat front section (18) of an angular recess (14) of the casing (2) of the pump (1).
