Zusammenfassung: | The invention relates to the construction of hydraulic machines. The assembly process forming the subject matter of the invention is characterised in that the shell 1 of the cone of the intake pipe 2 is mounted jointly with the joining band 3, these two parts being made beforehand as a single unit, and adjustment is carried out by arranging on the side with the foundation circle 4 a series of indentations 14, 19 in the joining band 3, then separating the parts 20, 21 thus formed until the inner curved surfaces of these parts coincide with the inner surface of the foundation circle 4, and thereafter closing the indentations 14, 19 by welding. The invention may be used in particular for designs of radial-axial hydraulic machines and those with adjustable blades.
L'INVENTION CONCERNE LA CONSTRUCTION DES MACHINES HYDRAULIQUES.LE PROCEDE D'ASSEMBLAGE FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QU'ON MONTE LA CHEMISE 1 DU CONE DU TUBE D'ASPIRATION 2 CONJOINTEMENT AVEC LA CEINTURE DE JONCTION 3, CES DEUX PARTIES ETANT REALISEES AU PREALABLE COMME UN SEUL BLOC, ON EFFECTUE L'AJUSTAGE EN MENAGEANT, DU COTE DU CERCLE DE FONDATION 4, UNE SERIE D'ENTAILLES 14, 19 DANS LA CEINTURE DE JONCTION 3, EN ECARTANT ENSUITE LES PARTIES 20, 21 AINSI FORMEES JUSQU'A FAIRE COINCIDER LES SURFACES INTERIEURES COURBES DE CES PARTIES AVEC LA SURFACE INTERIEURE DU CERCLE DE FONDATION 4, ET EN FERMANT APRES CELA LES ENTAILLES 14, 19 PAR SOUDAGE.L'INVENTION PEUT ETRE UTILISEE NOTAMMENT POUR LES ETUDES DES MACHINES HYDRAULIQUES RADIALES-AXIALES ET A PALES ORIENTABLES. |
