Abstract

"SELO MECANICO MANCALIZADO PARA BOMBAS DE CAVIDADE PROGRESSIVA". A qual compreende um corpo (1), num formato cilíndrico, fabricado em aço, podendo ser em outro material, internamente centralizado há uma luva (2) a qual se encaixa perfeitamente a haste/eixo da bomba (3), tendo dois jogos de o<39>rings (4) para ajuste e vedação; o corpo (1) possui alojamentos para mancais mancal (5), provido de um ou mais rolamentos que suportarão todas as reversões da haste, as vedações do conjunto mancalizado são por retentores (7A e 7B), instalados nos extremos dos rolamentos; o conjunto de selagem possui duas sedes estacionárias (17) e uma sede rotativa (19), a qual possui um sistema fechado de lubrificação, composto por um reservatório (22), dois tubos comunicantes (23), um manómetro (24) que opera sob pressão atmosférica, e um pressostato (25), o reservatório possui ainda um dreno (26) para substituição do óleo lubrificante e uma válvula de alívio (27) que poderá ou não ficar aberta; na região inferior ao selo mecânico há um carretel para manutenção (28), provido de tampas laterais (29), e dispositivo de sustentação (30) da haste/eixo da bomba, facilitando sensivelmente a desmontagem dos componentes da mesma.
