Abstract

APERFEIçOAMENTOS EM SELO MECáNICO MANCALIZADO PARA BOMBAS DE CAVIDADE PROGRESSIVA , que se aplicam a um selo mecânico (1) na forma de um corpo cilíndrico, recepcionando uma luva interna centralizada (2) a qual se encaixa perfeitamente à haste polida (3) da bomba, dita luva interna centralizada (2) movida por um dispositivo Clamp de arrastão (2A) o qual se encaixa perfeitamente e á solidário a haste polida (3) da bomba, permite movimentos axiais da haste, sendo que o seu principal objetivo à impedir a ejeção da mesma em casos de ruptura por fadiga de material ou causada por reversões bruscas, estando o seu curso limitado pelo flange inferior do motoredutor (S); a uma área de contorno central (6) identifica o local de atuação dos componentes do selo mecânico propriamente dito, como mancais, espaçadores, retentores, anéis de vedação e outros; numa instalação típica em poço petrolífero em terra, a invenção inclui o selo mecânico propriamente dito (1). acima do qual está o conjunto motoredutor (M). ao passo que, abaixo do referido selo mecânico, está acoplada a caixa de segurança porta "clamp" (4), que se acopla ao dito selo mecânico por meio de flange (7). enquanto um flange inferior (8) faz a ligação com o Te de fluxo (9). sendo que, imediatamente abaixo deste, está o flange de redução (l0), este encimando a cabeça do revestimento (11); a invenção propriamente dita inclui unia caixa de segurança porta "clamp" (4) que, em uso, dispensa o "clamp" propriamente dito (19). Bem como pelo uso de coletor metálico cilíndrico (26) na forma de um pequeno bujão externo ao corpo do selo mecânico (1), e ainda pelo Te de Fluxo (9) ser original em todas as instalações.
