Selon un mode préféré de réalisation, lesdits éléments de cartouches de filtration (2) sont montés co-axialement avec ledit support de renfort et d'adaptation (1) de façon à ce qu'un jeu fonctionnel existe entre le noyau tubulaire (11) desdits éléments de cartouches de filtration standard et le diamètre externe dudit support de renfort et d'adaptation (1) de sorte que le flux du fluide peut passer à travers de l'intégralité de la surface du média filtrant (10).According to a preferred embodiment, said filter cartridge elements (2) are mounted co-axially with said reinforcing and adapting support (1) so that a functional clearance exists between the tubular core (11). said standard filter cartridge members and the outer diameter of said reinforcing and fitting support (1) so that fluid flow can pass through the entire surface of the filter medium (10).
Pour des questions pratiques de mise en œuvre, lesdits éléments de cartouches de filtration (2) sont assemblées entre eux au niveau de leurs extrémités en contact par des jonctions (5) en colle ou par thermo-soudage de manière à former un seul élément filtrant.For practical implementation issues, said elements of filter cartridges (2) are assembled together at their ends in contact by junctions (5) in glue or by heat-sealing to form a single filter element .
Le soudage de pièces thermoplastiquès est une opération qui consiste à réunir entre elles et de façon irréversible deux ou plusieurs pièces. Une méthode utilisée pour l'assemblage consiste à élever la température sur les plans de joints jusqu'au point de fusion. Soit par l'utilisation des colles appropriées soit par un système électrique. Les parties chauffées sont mises en pression l'une contre l'autre et se retrouvent alors soudées entre elles. La température de fusion des pièces à souder doit être du même ordre de grandeur.The welding of thermoplastic parts is an operation that consists of joining together and irreversibly two or more parts. One method used for assembly is to raise the temperature on the joint plane to the melting point. Either by the use of the appropriate glues or by an electrical system. The heated parts are pressurized against each other and are then welded together. The melting temperature of the parts to be welded must be of the same order of magnitude.
