Title (EN) MOTOR REVERSAL SYSTEM FOR LINEAR DRIVE WELL PUMPS
(FR) SYSTÈME D’INVERSION DE MOTEUR POUR POMPES DE PUITS À ENTRAÎNEMENT LINÉAIRE
Abstract: front page image
(EN) A reciprocating well pump assembly has a barrel (29), a plunger (34), a travelling valve (31), and a standing valve (33). A linear converter (41) has a rotating component (43) and an axially movable component (47), the axially movable component (47) being cooperatively engaged with the plunger (34) for stroking the plunger (34). A motor (23) rotates the rotating component (43). A reversing means (63 or 65, 67) reverses direction of the rotating component (43) at a top of the up stroke and at a bottom of the down stroke.
(FR) La présente invention concerne un ensemble de pompe à mouvement alternatif qui comporte un cylindre (29), un piston (34), une soupape mobile (31) et une soupape fixe (33). Un convertisseur linéaire (41) comporte un composant rotatif (43) et un composant axialement mobile (47), le composant axialement mobile (47) venant en prise de façon coopérative avec le piston (34) pour causer la course du piston (34). Un moteur (23) met en rotation le composant rotatif (43). Un moyen d’inversion (63 ou 65, 67) inverse la direction du composant rotatif (43) au sommet de la course montante et à la base de la course descendante.
