Abstract
Une section détanchéité destinée à être utilisée dans un système de pompage submersible de fond de puits qui comprend une enveloppe, un tube de support de sac sétendant à travers lenveloppe, une tige positionnée à lintérieur du tube de support de sac et une plaque de sac reliée au tube de support de sac. La plaque de sac comprend de préférence un embout fixé au tube de support de sac et une bague de blocage mise en prise par filetage avec lembout. La plaque est configurée pour recevoir lextrémité ouverte dun sac étanche cylindrique fabriqué à partir dun polymère perfluoroalkoxy. Lembout comprend une tête conique qui seffile depuis un premier diamètre qui est légèrement plus grand que le diamètre intérieur du sac étanche à un second diamètre qui est légèrement plus petit que le diamètre intérieur du sac étanche. Ce mécanisme destiné à fixer le sac étanche élimine le besoin dun joint torique ou dautres joints mécaniques entre le sac et la plaque de sac.
