Abstract

SE REFIERE A MEJORAS PARA BOMBAS Y COMPONENTES DEL MISMO, DONDE: A) EL IMPULSOR COMPRENDE UNA CUBIERTA FRONTAL, UNA CUBIERTA POSTERIOR Y UNA PLURALIDAD DE PALETAS DE BOMBEO ENTRE LAS MISMAS; B) LA PARTE LATERAL DE LA BOMBA QUE COMPRENDE UNA SECCION DE PARED LATERAL QUE TIENE UNA CARA FRONTAL Y UNA CARA POSTERIOR, LA PARTE LATERAL DE LA BOMBA ADEMAS COMPRENDE UNA SECCION DE ENTRADA QUE SE EXTIENDE DESDE LA CARA FRONTAL Y DISPUESTO DURANTE SU USO PARA SER COAXIAL CON EL EJE DE ROTACION DEL IMPULSOR, LA CARA POSTERIOR QUE INCLUYE UNA REGION EXTERNA CON UN BORDE EXTERNO EN UN PLANO QUE ESTA SUSTANCIALMENTE EN ANGULO RECTO AL EJE DE ROTACION, UNA REGION INTERIOR CON UN BORDE INTERIOR Y UNA REGION INTERMEDIA ENTRE LAS REGIONES EXTERNAS E INTERNAS, EL PERFIL DE SECCION TRANSVERSAL DE LA CARA POSTERIOR EN LA REGION INTERMEDIA ESTANDO INCLINADA DESDE LA REGION EXTERIOR CON RESPECTO AL PLANO, Y EL PERFIL DE SECCION TRANSVERSAL DE LA CARA POSTERIOR EN LA REGION INTERIOR. LAS MEJORAS SON APLICADAS GENERALMENTE A BOMBAS DE SUSPENSION CENTRIFUGA.IT REFERS TO IMPROVEMENTS FOR PUMPS AND COMPONENTS OF THE SAME, WHERE: A) THE IMPELLER INCLUDES A FRONT COVER, A REAR COVER AND A PLURALITY OF PUMPING PADS AMONG THEM; B) THE SIDE PART OF THE PUMP INCLUDING A SIDE WALL SECTION THAT HAS A FRONT FACE AND A BACK FACE, THE SIDE PART OF THE PUMP ALSO INCLUDES AN INLET SECTION EXTENDING FROM THE FRONT FACE AND DISPOSED DURING USE FOR BE COAXIAL WITH THE AXIS OF ROTATION OF THE IMPELLER, THE BACK FACE INCLUDING AN OUTER REGION WITH AN OUTER EDGE IN A PLANE THAT IS SUBSTANTIALLY AT A RIGHT ANGLE TO THE AXIS OF ROTATION, AN INTERIOR REGION WITH AN INTERIOR EDGE AND AN INTERMEDIATE REGION BETWEEN THE REGIONS EXTERNAL AND INTERNAL, THE REAR FACE CROSS SECTION PROFILE IN THE INTERMEDIATE REGION IS INCLINED FROM THE OUTSIDE REGION WITH RESPECT TO THE PLANE, AND THE REAR FACE CROSS SECTION PROFILE IN THE INTERIOR REGION. THE IMPROVEMENTS ARE GENERALLY APPLIED TO CENTRIFUGAL SUSPENSION PUMPS.
