Title (EN) DIAPHRAGM PUMP, IN PARTICULAR FOR USE AS A DETERGENT DOSAGE PUMP
(FR) POMPE À DIAPHRAGME, À UTILISER EN PARTICULIER COMME POMPE DE DOSAGE DE DÉTERGENT
Abstract:
(EN) A diaphragm pump (10), in particular for use as a detergent dosage pump, comprises a pump housing (12), wherein the pump housing (12) comprises at least a first connector (14) and a second connector (46), a fluid chamber (16) connected fluid permeable to the at least first connector (14) and second connector (46), a reciprocating moveable diaphragm (18) defining a wall of the fluid chamber (16),at least a first check valve (44) allocated to the first connector (14) and a second check valve (48) allocated to the second connector (46), a first eccentric (24) and a second eccentric (32),a driving means (30) for actuating the first and second eccentric (24, 32), wherein the diaphragm (18) is actuated by the first eccentric (24) by a connector rod (20), and the first check valve (44) and the second check valve (48) are actuated by the second eccentric (32). This has the advantage that by actuating the first and second check valve (44, 48) depending on the movement of the diaphragm (18), in particular by a coordinated rotational movement of the first and second eccentric (24, 32), a gas, for example air, trapped inside the fluid chamber (16) may be evacuated from the fluid chamber, thus providing a self-bleeding diaphragm pump (10).
(FR) Pompe (10) à diaphragme, à utiliser en particulier comme pompe de dosage de détergent, comprenant un carter (12) de pompe. Le carter (12) de pompe comprend au moins un premier raccord (14) et un second raccord (46), une chambre de fluide (16) raccordée au(x) premier(s) raccord(s) (14) et au second raccord (46) de manière perméable aux fluides, un diaphragme mobile (18) à mouvement de va-et-vient délimitant une paroi de la chambre de fluide (16), au moins un premier clapet de retenue (44) affecté au premier raccord (14) et un second clapet de retenue (48) affecté au second raccord (46), un premier excentrique (24) et un second excentrique (32), un moyen d'entraînement (30) destiné à actionner les premier et second excentriques (24, 32), le diaphragme (18) étant actionné par le premier excentrique (24) par une tige (20) de raccord, et le premier clapet de retenue (44) et le second clapet de retenue (48) étant actionnés par le second excentrique (32). Ceci est avantageux en ce que, lors de l'actionnement des premier et second clapets de retenue (44, 48) en fonction du déplacement du diaphragme (18), en particulier par un déplacement rotatif coordonné des premier et second excentriques (24, 32), un gaz, par exemple de l'air, piégé à l'intérieur de la chambre de fluide (16) peut être évacué de la chambre de fluide, créant ainsi une pompe (10) à diaphragme à purge automatique.
