Abstract

DISPOSITIVO DE ENTANQUIDAD DEL ARBOL DE TRANSMISION DE UNA BOMBA PARA FLUIDO DE ALTA PRESION.CONSISTENTE EN UNA SERIE DE JUNTAS (33, 34, 35 Y 45), UNA DE LAS CUALES ES DE TIPO HIDROSTATICO (33) DE FUGA DE LIQUIDO, ENTRE EL ARBOL (27) Y UNA CAJA QUE LO RODEA (30); NECESITANDO ESTA JUNTA PARA SU FUNCIONAMIENTO UNA DIFERENCIA DE PRESION ENTRE LA PARTE DE ESPACIO ANULAR SITUADA AGUAS ARRIBA, HACIA LA VOLUTA (21) Y LA PARTE SITUADA AGUAS ABAJO. LA CAMARA ES ALIMENTADA DE FLUIDO A ALTA PRESION POR UN CIRCUITO DE ALIMENTACION (36, 40) QUE LLEVA UNAJUNTA AUXILIAR TIPO MECANICO (45) Y UNA CANALIZACION (47) QUE ENLAZA LAS DOS PARTES DE LA CAMARA SITUADAS AGUAS ARRIBA (46A) Y AGUAS ABAJO (46B) DE DICHA JUNTA.
