Abstract

"DISPOSITIVO DE VEDAçãO PARA UMA BOMBA DE áGUA, DISPOSITIVO DE SUPORTE, ROTAçãO PARA UMA BOMBA DE áGUA E UMA BOMBA DE áGUA". Uma estrutura de uma bomba de água é proporcionada, sem aumentar o seu custo, ou sem ampliar o seu tamanho para aperfeiçoar a durabilidade da bomba de água. Um dispositivo de vedação é compreendido de um anel de vedação 13 e um distribuidor 14 em combinação, a fim de impedir matéria estranha de avançar no mancal de rolamento 6a. A quantidade de compressão <sym> da segunda virola de vedação 23, que ocorre quando a borda de ponta da segunda virola de vedação 23 do anel de vedação 13 entra em contato com a superfície periférica externa da seção cilíndrica do lado do diâmetro externo 26, que é formada na borda periférica externa do distribuidor 14, é pelo menos 1/10 e até 7/10 da altura da segunda virola de vedação 23 em um estado livre. Além disso, a irregularidade de uma porção da superfície periférica externa da seção cilíndrica do lado do diâmetro externo 26 com a qual a borda de ponta da segunda virola de vedação 23 entra em contato deslizante é de 0,2 <109>m a 2,0 <109>m na média aritmética Ra ou é de 0,8 <109>m a 8,0 <109>m na altura máxima Ry.
