Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Testen eines Hydrauliksystems (1) aufweisend eine Pumpe (2), die in einer ersten Drehrichtung (3) Fluid zu einem ersten Verbraucher (4) für eine Volumenstromfunktion fördert und in einer zweiten Drehrichtung (5) Fluid zu zumindest einem zweiten Verbraucher (6) für eine Betätigungsfunktion fördert, wobei zumindest einer der folgenden Schritte ausgeführt wird: Testen einer hydraulischen Bereitschaft des Hydrauliksystems (1); Ansaugen von Fluid in das Hydrauliksystem (1); Entlüften des Hydrauliksystems (1). Die Erfindung betrifft auch ein Hydrauliksystem (1) zur Durchführung eines solchen Verfahrens, mit einer Pumpe (2), die in einer ersten Drehrichtung (3) für eine Volumenstromfunktion und in einer zweiten Drehrichtung (5) für eine Betätigungsfunktion antreibbar ist.
(EN)
The invention relates to a method for testing a hydraulic system (1), having a pump (2) which, in a first direction of rotation (3), conveys fluid to a first consumer (4) for a volume flow function and, in a second direction of rotation (5), conveys fluid to at least one second consumer (6) for an actuation function, wherein at least one of the following steps is performed: testing hydraulic readiness of the hydraulic system (1); drawing fluid into the hydraulic system (1); ventilating the hydraulic system (1). The invention also relates to a hydraulic system (1) for carrying out such a method, having a pump (2) which can be driven in a first direction of rotation (3) for a volume flow function and can be driven in a second direction of rotation (5) for an actuation function.
(FR)
L’invention concerne un procédé de contrôle d’un système hydraulique (1) comprenant une pompe (2), qui refoule dans un premier sens de rotation (3) du fluide vers un premier consommateur (4) pour une première fonction de flux volumique et qui refoule dans un deuxième sens de rotation (5) du fluide vers au moins un deuxième consommateur (6) pour une fonction d’actionnement, au moins une des étapes suivantes étant exécutée : contrôle d’une disponibilité hydraulique du système hydraulique (1) ; aspiration de fluide dans le système hydraulique (1) ; purge du système hydraulique (1). L’invention concerne aussi un système hydraulique (1) pour l'exécution d’un tel procédé, comprenant une pompe (2), qui peut fonctionner dans un premier sens de rotation (3) pour une fonction de flux volumique et dans un deuxième sens de rotation (5) pour une fonction d’actionnement.
