Abstract

LA CAJA DE ESTATOR DE PLACA DE METAL (1), PARA BOMBAS CENTRIFUGAS RADIALES, INCLUYE UN CUERPO PRINCIPAL (2), UNA VOLUTA DE DIFUSION (10), UNA ENTRADA DE SUCCION AXIAL (3) Y UNA SALIDA DE DESCARGA RADIAL (4) EN LA SALIDA DE LA VOLUTA DE DIFUSION. LA VOLUTA ESTA FORMADA POR UN CANAL EN FORMA DE CIRCUNFERENCIA (11) QUE ESTA DEFINIDO EN LA PARED LATERAL DEL CUERPO PRINCIPAL Y TIENE UNA SECCION EN CRUZ TRANSVERSAL RADIAL QUE AUMENTA UNIFORMEMENTE HACIA LA SALIDA DE LA VOLUTA. AL MENOS UNA PORCION DEL CANAL TIENE, EN LA SECCION EN CRUZ TRANSVERSAL, UNA PROFUNDIDAD RADIAL SUBSTANCIALMENTE CONSTANTE Y UNA ANCHURA AXIAL QUE SE INCREMENTA DE MANERA UNIFORME.
