Description

Die Erfindung betrifft einen Adapteraufsatz für eine Einrichtung zum Anschließen von Rohrleitungen an den Verteilerabschnitt einer Flüssigkeitsbehandlungsvorrichtung, insbesondere eines Hydrauliköl-Luftkühlers, der üblicherweise in den Rücklauf eines Hydrauliköl-Arbeitskreises von bewegten oder stationären Anlagen eingeschaltet ist. Die vom Hydrauliköl durchströmten, zu einem parallelepipedischen Paket zusammengefaßten Kühlelemente des Kühlers bestehen in der Regel aus Aluminiumplatten und -stäben, die von Luftlamellen umgeben und mit einem sich über die Oberseite des Paketes erstreckenden kastenförmigen Verteilerabschnitt verbunden sind. Die Kühlelemente werden außerdem von einem angebauten Ventilator beaufschlagt.The invention relates to an adapter attachment for a device for connecting pipes to the manifold portion of a liquid treatment apparatus, in particular a hydraulic oil-air cooler, which is usually turned on in the return of a hydraulic oil working group of moving or stationary equipment. The cooling elements of the radiator, through which hydraulic oil flows and which are combined into a parallelepipedic packet, are generally made of aluminum plates and rods, which are surrounded by air louvers and connected to a box-shaped distributor section extending over the top of the package. The cooling elements are also acted upon by a mounted fan.

Um zu vermeiden, daß für verschiedene Kühlermodelle unterschiedlich dimensionierte Anschlüsse auf Lager gehalten werden müssen und um den Einbau des Kühlers zu erleichtern, ist gemäß dem EP 0 983 475 B1 der parallelepipedische Verteilerabschnitt der Flüssigkeitsbehandlungsvorrichtung in einem Eckbereich mit einer Abflachung versehen, in welcher ein Flüssigkeitsdurchlaß vorgesehen ist. Ferner ist ein auf diese Abflachung aufsetzbarer, im wesentlichen pyramidenförmiger hohler Adapteraufsatz vorgesehen, der eine Basis mit einem dem Flüssigkeitsdurchlaß der Abflachung entsprechenden Flüssigkeitsdurchlaß und einen Rohrleitungsanschluß aufweist. Dies ermöglicht es, den Adapteraufsatz mit unterschiedlicher Orientierung an der Eckabflachung derart zu montieren, daß der Rohrleitungsanschluß je nach Bedarf nach hinten, nach oben oder nach der Seite weist. Zugleich können unterschiedliche Adapteraufsätze vorrätig gehalten werden, die an die jeweils anzuschließenden Rohrleitungen hinsichtlich des Durchmessers und des Gewindes ihrer Anschlußöffnung angepaßt sind, so daß in wirtschaftlich vorteilhafter Weise nur ein einziges Modell der Flüssigkeitsbehandlungsvorrichtung erzeugt und auf Lager gehalten werden muß.In order to avoid that differently dimensioned connections must be kept in stock for different radiator models and to facilitate the installation of the radiator, according to the EP 0 983 475 B1 the parallelepipedic distributor section of the liquid treatment device is provided in a corner region with a flattening in which a liquid passage is provided. Further provided is a substantially pyramid-shaped hollow adapter attachment which can be placed on this flattening and which has a base with a fluid passage corresponding to the fluid passage of the flattening and a pipe connection. This makes it possible to mount the adapter attachment with a different orientation to the Eckabflachung such that the pipe connection, as required, facing backwards, upwards or to the side. At the same time different adapter attachments can be kept in stock, which are adapted to the respective pipes to be connected in terms of the diameter and the thread of their connection opening, so that in an economically advantageous manner only a single model of the liquid treatment device must be generated and kept in stock.

Ein Problem besteht bei dieser Anschlußeinrichtung und ihrem Adapteraufsatz aber darin, daß der für die Regelung des Kühlers erforderliche Temperatursensor an irgendeiner Stelle der Hydraulikölleitung gesondert eingebaut und angeschlossen werden muß, oder im Kühler selbst, was konstruktiv und einbautechnisch relativ aufwendig ist und eine Nacharbeitung der Gewinde nach der Wärmebehandlung notwendig macht, wodurch eine Verunreinigung des Kühlers eintreten kann.A problem with this connection device and its adapter attachment but is that the temperature sensor required for the control of the cooler must be installed and connected separately at any point of the hydraulic oil line, or in the cooler itself, which is relatively complex in terms of design and installation and a rework of the thread after the heat treatment is necessary, whereby contamination of the radiator may occur.

Die vorliegende Erfindung zielt deshalb darauf ab, eine verbesserte Anschlußeinrichtung zu schaffen, die geringeren Aufwand als bisher für die Temperaturermittlung und -regelung erfordert.The present invention therefore aims to provide an improved terminal device which requires less effort than previously for the temperature determination and control.
