Abstract

resumo patente de invenção: "perfil de difusor com protuberâncias e aletas". a presente invenção refere-se a um conjunto de bomba submersível elétrica (esp) que aumenta a eficácia de bomba e cabeça de bomba com um difusor que inclui uma aleta de difusor que tem uma superfície de baixa pressão com um comprimento maior do que um comprimento de uma superfície de alta pressão da aleta. a aleta de difusor inclui uma borda anterior em uma extremidade a jusante da aleta e uma borda posterior em uma extremidade a montante da aleta. a superfície de alta pressão curva se estende entre a borda anterior e a borda posterior. a superfície de baixa pressão curva se estende entre a borda anterior e a borda posterior oposta à superfície de alta pressão. a superfície de baixa pressão tem um amortecedor formado na mesma para aumentar o comprimento da superfície de baixa pressão de modo que o fluido que flua ao longo da superfície de baixa pressão seja substancialmente laminar, aumentando, assim, a eficácia de bomba e cabeça de bomba.
