Abstract

"BOMBA DE áGUA". Uma bomba de água 1 compreende: um alojamento 2, apresentando uma unidade de apoio 4, a qual fica fixa a um apoio em esfera 13 que suporta um eixo rotativo 12, com o qual se acopla um impulsionador 11; e uma passagem de vapor 17 e uma passagem de drenagem 19, as quais se estendem de forma linear na direção radial e se comunicam com um espaço interno 16, definido entre o apoio em esfera 13 e uma vedação mecãnica 15. Uma vez que a passagem de drenagem 19 passa através de uma nervura de passagem 8 que se estende para o exterior na direção radial, a partir da superfície externa da unidade de apoio 4, a resistência ao fluxo de ar da passagem de drenagem 19 é aumentada, sendo maior do que da passagem de vapor 17 e impedindo a entrada do pó. Além disso, posicionada acima da passagem de vapor 17, para impedir a entrada do pó, se encontra uma nervura circunferente 7, que é provida apenas ao longo de parte da circunferência."Water pump". A water pump 1 comprises: a housing 2, having a support unit 4, which is fixed to a ball support 13 that supports a rotating axis 12, with which a pusher 11 is coupled; and a vapor passage 17 and a drain passage 19, which extend in a linear direction in the radial direction and communicate with an internal space 16, defined between the ball bearing 13 and a mechanical seal 15. Once the passage drain 19 passes through a passage rib 8 that extends outwards in the radial direction, from the outer surface of the support unit 4, the airflow resistance of the drain passage 19 is increased, being greater than vapor passage 17 and preventing dust from entering. In addition, positioned above the vapor passage 17, to prevent dust from entering, there is a circumferential rib 7, which is provided only along part of the circumference.
