Abstract

SE DIFUNDE UN CUERPO DE BOMBA FABRICADO POR PRENSA DE MOLDURAR DE CHAPA DE ACERO Y QUE INCLUYE UN CUERPO DIFUSOR QUE RODEA UN IMPULSOR DE BOMBA PARA FORMAR UNA TRAYECTORIA DE FLUIDO ALREDEDOR DEL IMPULSOR DE LA BOMBA. EL AREA DE LA SECCION TRANSVERSAL DE LA TRAYECTORIA DEL FLUIDO SE INCREMENTA GRADUALMENTE HACIA UN PUERTO DE DESCARGA DEL CUERPO DE LA BOMBA. EL CUERPO DE LA BOMBA INCLUYE UN CUERPO DE CARCASA QUE ESTA FORMADO PRIMERO POR PRENSA DE MOLDURAR DE CHAPA DE METAL DENTRO DE UNA FORMA DE VASO CILINDRICO QUE TIENE UNA PORCION DE APERTURA EN UN LADO DEL MISMO Y UNA PORCION DEL FONDO CERRADA EN EL OTRO LADO DEL MISMO, Y LUEGO POR PRENSA DE MOLDURAR DEL CUERPO DE LA CARCASA EN FORMA DE VASO CILINDRICO DE FORMA QUE TENGA UNA PORCION DE DIFUSOR RADIALMENTE HACIA EL EXTERIOR EXPANDIDO DESDE UNA SUPERFICIE CILINDRICA DEL CUERPO DE LA CARCASA EN UNA PORCION INTERMEDIA AXIALMENTE DE LA MISMA QUE ESTA OPUESTA RADIALMENTE AL IMPULSOR DE LA BOMBA, UNA BRIDA DE LA CARCASA HACIA FUERA EXTENDIENDOSEDESDE LA PORCION DE APERTURA Y UNA APERTURA QUE SIRVE COMO PUERTO DE SUCCION EN LA PORCION DEL FONDO. COMO NO SE FACILITA MIEMBRO DIFUSOR DENTRO DE LA CARCASA DE LA BOMBA PARA FORMAR LA PORCION DE DIFUSION, EL DIAMETRO EXTERIOR DE LA CARCASA DE LA BOMBA SE PUEDE DISMINUIR E IGUALMENTE LA FORMA DE LA TRAYECTORIA DEL LIQUIDO EN LA CARCASA DE DIFUSION SE PUEDE HACER LISA.
