Definitions

  • the drive components comprise a pressure booster and a device with which the pumped lubricant is uniformly distributed to individual supply lines 12 and thus to the individual lubricant nozzles of an associated cylinder 8.
  • Fig. 3 shows the lubrication module 1 after assembly of the components or organs 3, 4, 5.
  • the pressure sensor 4 is inserted into a recess 24 of the base body 2, the controllable valve 5 in a recess 25 (see Fig. 2 ).
  • Said organs 3, 4, 5 have different functions, so that by their integration in the lubrication module 1 and the integration of the T-shaped branch for the servo oil present a functional combination. Through this functional association, there are savings in costs and space requirements.
  • the assembly is also simplified. In case of a defect will a lubrication module 1 simply replaced by an intact (new or revised) module 1. This allows an acceleration of a repair, which in turn reduces costs.
  • the main body 2 in which the lubricant pump, not shown, is contained, has two connection points 6a and 6b for the servo oil.
  • the central tube 161 of the double-walled pipe 16 is connected (with jacket tube 162) to a pipe end 60 of the base body 2, for example with a screw connection.
  • Flanges 163 at the ends of the jacket tube 162 are screwed onto the base body 2.
  • a channel 61 is integrated with a T-shaped branch and a branch 62 for the servo oil. This channel 61 connects the connection points 6a and 6b, while the branch 62 establishes a closable by the valve 5 lockable connection to the drive components of the lubricant pump.
  • the controller 10 of the higher-level control system 100 is freely programmable, so that the lubricant pump can be controlled or regulated in such a way that the quantity and / or the time of the delivered lubricant can be set as a function of the already mentioned operating parameters.

Claims (9)

  1. Système de lubrification de cylindre pour une pluralité de cylindres (8) dans un moteur à combustion interne à piston alternatif, en particulier un grand moteur Diesel à deux temps à balayage longitudinal, pour appliquer des lubrifiants dans les cylindres sur des faces de roulement de piston (80) avec à chaque fois une pluralité de buses de lubrifiant (7), où le lubrifiant peut être amené d'une manière dosée par des pompes de lubrifiant convoyant par intermittence et d'une manière pulsée aux buses de lubrifiant, et des composants d'entraînement des pompes de lubrifiant sont raccordés à une conduite de guidage d'huile, à savoir une conduite guidant une servo-huile ou huile de cylindre, en particulier une conduite à paroi double (16),
    caractérisé en ce qu'il est associé à chaque cylindre un module lubrifiant (1) avec une pompe de lubrifiant, en ce que la pompe de lubrifiant forme un corps de base mécaniquement stable (2) par lequel est réalisée une intégration de divers organes (3, 4, 5), en ce que ces organes sont a) une unité de commande locale (3), b) un capteur de pression (4) disposé entre la pompe de lubrifiant et la buse de lubrifiant pour la surveillance du convoyage par intermittence du lubrifiant, c) une soupape (5) pouvant être commandée pour l'huile et d) d'autres organes optionnels, comme par exemple un accumulateur, où sont prévus deux emplacements de raccordements (6a, 6b) pour la conduite de guidage d'huile au corps de base, et un canal (61) avec un branchement en forme T (62) pour l'huile est intégré dans le corps de base, et ce canal relie les emplacements de raccordement tandis que le branchement établit une liaison pouvant être fermée d'une manière commandée par la soupape aux composants d'entraînement de la pompe de lubrifiant.
  2. Système de lubrification selon la revendication 1, caractérisé en ce que chaque unité de commande locale (3) forme un noeud intelligent d'un système de commande superposé (100).
  3. Système de lubrification selon la revendication 2, caractérisé en ce que le système de commande superposé (100) comprend des lignes d'alimentation (102) et au moins un bus de champ (101), en particulier un bus CAN, et en ce que les unités de commande locales (3) sont connectées aux lignes d'alimentation et au bus de champ pour pouvoir établir avec le système de commande superposé un échange de données (103, 310), où avantageusement les lignes d'alimentation et le bus de champ, pour des raisons de redondance, sont réalisés en double.
  4. Système de lubrification selon la revendication 2 ou 3, caractérisé en ce que le capteur de pression (4) est relié au système de commande local (3) par une ligne de transmission de signaux (43).
  5. Système de lubrification selon l'une des revendications 2 à 4, caractérisé en ce que la soupape (5) pouvant être commandée pour la servo-huile est reliée au système de commande local (3) par une ligne de transmission de signaux (35).
  6. Système de lubrification selon l'une des revendications 2 à 4, caractérisé en ce que le système de commande superposé (100) peut être programmé librement de sorte que la pompe de lubrifiant peut être commandée ou régulée de façon que la quantité et/ou l'instant de lubrifiant convoyé puisse être réglé en fonction de divers paramètres de fonctionnement, comme par exemple le nombre de tours, la charge, la température de cylindre, l'épaisseur du film de lubrification dans le cylindre (8) ou d'autres paramètres de fonctionnement ou aussi en fonction de la qualité d'un combustible, du lubrifiant (8) ou d'autres carburants.
  7. Moteur à combustion interne à piston alternatif, en particulier grand moteur Diesel à deux temps avec balayage longitudinal, qui comprend un système de lubrification de cylindre selon l'une des revendications 1 à 6.
  8. Procédé de lubrification d'une face de roulement de piston (80) avec un système de lubrification de cylindre selon l'une des revendications 1 à 6, caractérisé en ce que par le capteur de pression (4), le convoyage par intermittence du lubrifiant est surveillé en ce qui concerne l'instant de l'émission et le coup de bélier produit, et est régulé en ce qui concerne des valeurs de consigne qui sont prédéfinies ou qui peuvent dépendre d'autres paramètres, par le système de commande (100) superposé.
  9. Procédé selon la revendication 8, caractérisé en ce que des grandeurs mesurées par le capteur de pression (4) sont transmises au moins partiellement comme données (310) au système de commande superposé (100) de sorte que le cas échéant une mesure de remède requise puisse être activée et/ou une alarme puisse être déclenchée.
