Abstract:
(EN) The invention relates to an electrical pump drive for positive displacement pumps having pistons moved in an oscillating manner. The electrical pump drive is characterised in that the electrical pump drive comprises a rotary magnet (3) which has at least one electromagnet (30; 30a, 30b) and an armature (32) which can swivel about an axis and which is pivotable alternately between two working points by means of excitation of the at least one electromagnet (30; 30a, 30b); wherein the armature (32) is configured for coupling to a piston (2) which is moved in an oscillating manner.
(FR) L'invention concerne un entraînement de pompe électrique pour pompes volumétriques comportant un piston à mouvement oscillant. Cet entraînement de pompe électrique est caractérisé en ce qu'il comporte un aimant rotatif (3) comprenant au moins un électroaimant (30; 30a, 30b) ainsi qu'une armature (32) pouvant pivoter autour d'un axe et pouvant être déplacée en alternance entre deux points de travail sous l'effet de l'excitation de l'électroaimant ou des électroaimants (30; 30a, 30b), cette armature (32) étant conçue pour être accouplée à un piston à mouvement oscillant.
(DE) Es wird ein elektrischer Pumpenantrieb für Verdrängerpumpen mit oszillierend bewegten Kolben vorgeschlagen. Der elektrische Pumpenantrieb zeichnet sich dadurch aus, dass er einen Drehmagnet (3) umfasst, der wenigstens einen Elektromagnet (30; 30a, 30b) und einen um eine Achse schwenkbaren Anker (32) aufweist, der vermittels Erregung des wenigstens einen Elektromagnets (30; 30a, 30b) zwischen zwei Arbeitspunkten wechselseitig verschwenkbar ist; wobei der Anker (32) zur Koppelung mit einem oszillierend bewegten Kolben (2) eingerichtet ist.
