Abstract

Un rotor de bomba centrífuga incluye una carcasa frontal, una carcasa posterior, y una pluralidad de álabes de bombeo entre las mismas, y cada álabe de bombeo tiene un borde delantero en la zona de la entrada del rotor y un borde de salida, la carcasa frontal posee una cara interna curva en la zona de la entrada del rotor, la cara interna curva tiene un radio de curvatura (Rs) que oscila entre 0.05 y 0.16 del diámetro externo del rotor (D2). La carcasa posterior incluye una cara principal interna y un talón que posee un perfil curvo con una punta o cúspide en la zona del eje central que se extiende hacia la carcasa frontal, existe una zona de transición curva entre la cara principal interna y el talón. Fr es el radio de curvatura de la zona de transición, y la relación Fr/D2 oscila entre 0.32 y 0.65. También se describen otras relaciones de varias dimensiones del rotor.
