Title
(DE) HYDRAULIKPUMPE MIT EIGENER ANTRIEBSEINHEIT
(EN) HYDRAULIC PUMP COMPRISING AN INDEPENDENT DRIVE UNIT
(FR) POMPE HYDRAULIQUE PRESENTANT UNE UNITE D'ENTRAINEMENT QUI LUI EST PROPRE
Abstract
(DE)
Die Hydraulikpumpe weist eine eigene Antriebseinheit auf, die zumindest von zwei gegeüberstehenden und zu einem Gehäuse (1) befestigten koaxialen Pumpenblöcken (12, 13) zusammengestellt ist. Ein Kolben (8) des Pumpenblocks (12) ist mit einem Kolben (8) von Pumpenblock (13) durch Bolzen (14) fest so verbunden, dass solange sich der Kolben (8) des Pumpenblocks (12) in der Totlage beim Gehäuse (1) befindet, ist der Kolben (8) von Pumpenblock (13) in der Totlage an der vom Gehäuse (1) abgeneigten Seite und umgekehrt. Durch eine Kolbenbewegung wird Flüssigkeit in der Produktleitung gepumpt. Die Bewegung von Kolben (8) wird durch gesteuerte Prozesse in Brennkammern (9) ermöglicht. Die Brennkammern (9) sind aus Köpfen (3) und aus mit dem Gehäuse (1) verbundenen Hülsen (5) und aus innerhalb des Kolbenkopfes befestigten Zapfen (7) gefertigt. Zum Pumpenblock (12), (13) ist es möglich, eine Kompressorkammer (18) beizufügen, deren Membrane oder Kolben (19) mit dem Kolben (8) verknüpft ist. Die Pumpenblöcke (12) und (13) sind entweder an den Hauben (11) oder an den Kompressorkammern (18) zusammengebunden. Sie können auch an dem Gehäuse (1) zusammengebunden werden, das in dem Fall gemeinsam ist.
(EN)
Disclosed is a hydraulic pump comprising an independent drive unit which is composed of at least two opposite coaxial pump blocks (12, 13) that are fixed to a housing (1). A piston (8) of the first pump block (12) is connected in a fixed manner to a piston (8) of the second pump block (13) by means of bolts (14) such that the piston (8) of the second pump block (13) is in the dead-center position on the side located opposite the housing (1) as long as the piston (8) of the first pump block (12) is in the dead-center position at the housing (1) and vice versa. Liquid is pumped into the product conduit by means of a piston movement. Piston (8) movement is made possible by controlled processes in combustion chambers (9) comprising heads (3), sleeves (5) that are connected to the housing (1), and pins (7) which are fastened within the piston head. The pump block (12), (13) can be provided with a compressor chamber (18), the membrane or piston (19) of which is linked to the piston (8). The pump blocks (12 and 13) are joined at the hoods (11) or compressor chambers (18) or can also be joined at the housing (1), which is common to the pump blocks (12 and 13) if that is the case.
(FR)
L'invention concerne une pompe hydraulique présentant une unité d'entraînement qui lui est propre, ladite pompe étant formée par au moins deux blocs (12, 13) coaxiaux, se faisant face, fixés par rapport à un boîtier (1). Un piston (8) du bloc (12) est relié solidement à un piston (8) du bloc (13) par des boulons (14) de sorte que, tant que le piston (8) du bloc (12) se trouve au point neutre dans le boîtier (1), le piston (8) du bloc (13) se trouve au point neutre sur le côté incliné à partir du boîtier (1) et réciproquement. Un mouvement du piston entraîne le pompage du liquide dans la conduite de produit. Des processus régulés dans les chambres de combustion (9) permettent le mouvement du piston (8). Les chambres de combustion (2) sont réalisées à partir de têtes (3), à partir de douilles (5) raccordées boîtier (1) et à partir de tourillons (7) fixé à l'intérieur de la tête de piston. Il est possible d'ajouter aux blocs (12), (13) une chambre de compresseur (18) dont les membranes ou les pistons (19) sont reliés au piston (8). Les blocs (12) et (13) sont soit raccordés au capot (11) soit aux chambres de compresseur (18). Ils peuvent également être raccordés au boîtier (1), auquel cas ce dernier est commun aux deux blocs.
