Title (EN) PROGRESSIVE CAVITY PUMPS USING COMPOSITE MATERIALS
(FR) POMPES A CAVITE PROGRESSIVE COMPORTANT DES MATERIAUX COMPOSITES
Abstract:
(EN) The stator, rotor and/or flex shaft of a progressive cavity pump is made up of composite materials, e.g., fiberglass and resin, in a variety of combinations with and without bonded resilient elastomers. The composites are formulated to provide resiliency and non-resiliency where needed. The flex shaft between the rotary power source and the rotor is made of composite materials and designed to absorb the orbital and gyrational movement of the rotor.
(FR) Le stator, le rotor ou l'arbre souple d'une pompe à cavité progressive, telle qu'une pompe de Moineau, sont fabriqués en matériaux composites, par exemple des fibres de verre et de la résine, combinés de façon variée et comportant ou non des élastomères élastiques agglomérés. La formulation de ces composites leur confère une élasticité et une non élasticité, si nécessaire. L'arbre souple entre la source d'énergie rotative et le rotor est fabriqué en matériaux composites et conçu pour amortir le déplacement orbital et giratoire du rotor.
