Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Notschmierung der Wellenlager eines Abgasturboladers bei ausfallender Schmierölversorgung.The The invention relates to a device for emergency lubrication of the shaft bearings of an exhaust gas turbocharger when the lubricating oil supply fails.
Der Erfindung liegt die Aufgabe zugrunde, eine derartige Vorrichtung mit einem einfachen Aufbau zu schaffen, die eine ausreichende Schmierung der Wellenlager bei Ausfall der Schmierölversorgung sicherstellt.The The invention has for its object such a device with a simple structure that provides adequate lubrication of the Shaft bearings in the event of a failure of the lubricating oil supply.
Erfindungsgemäß wird dies dadurch erreicht, dass eine senkrecht angeordnete, an mindestens eine Schmierölversorgungsleitung angeschlossene Ringleitung vorgesehen ist, von der unten eine Zuführleitung zur Turbinenwellenlagerung und oben eine Zuführleitung zur Verdichterwellenlagerung sowie eine Stichleitung zu einem Vorratstank abgehen und die Stichleitung einen stets offenen Durchtrittsquerschnitt zum Vorratstank sowie ein bei Druckabfall in der Ringleitung in Rückflussrichtung vom Vorratstank öffnendes Rückschlagventil aufweist.According to the invention thereby achieved that a vertically arranged, at least one Oil supply line Connected ring line is provided, from the bottom of a feed line for turbine shaft bearing and above a feed line for compressor shaft bearing and a branch line to a storage tank and the branch line an always open passage cross-section to the storage tank as well one that opens in the return line from the storage tank when there is a pressure drop in the ring line check valve having.
Die Erfindung zeichnet sich dadurch aus, dass mit Ausnahme eines Rückschlagventiles keine weiteren bewegten Teile vorhanden sind. Dennoch wird nicht nur eine ausreichende Schmierung der Wellenlager bei einem kurzfristigen Ausfall der normalen Schmierung, sondern auch eine Notschmierung bei langfristigen Ausfall der Schmierung mit Stillsetzen der Laufräder erreicht, wobei zusätzlich eine Kühlung der stärker aufgeheizten Turbinenwellenlager durch eine Restmenge von Schmieröl aus dem Vorratstank erreicht wird.The The invention is characterized in that, with the exception of a check valve there are no other moving parts. Still won't only adequate lubrication of the shaft bearings for a short-term Failure of normal lubrication, but also emergency lubrication achieved in the long-term failure of the lubrication with the impellers stopped, being additional a cooling the stronger heated turbine shaft bearing by a residual amount of lubricating oil from the storage tank is achieved.
Vorteilhaft ist der Vorratstank durch eine senkrechte Wand in zwei Abschnitte unterteilt, die mittels einer Durchtrittsöffnung miteinander in Verbindung stehen und in dem die Stichleitung aufnehmenden Abschnitt ein zu einem entlüfteten Schmierölsammelbehälter führendes Überlaufrohr mündet. Durch die Unterteilung des Vorratstanks lässt sich erreichen, dass in dem Abschnitt, in dem das Überlaufrohr nicht mündet, beim Füllen ein Luftpolster gebildet wird, das den Schmieröldruck erreicht und daher sicherstellt, dass das Rückschlagventil bei Ausfall der normalen Schmierung öffnet und dann aus dem Vorratstank Schmieröl zunächst unter Druck in die Ringleitung austritt.Advantageous is the storage tank by a vertical wall in two sections divided, which is connected to one another by means of a passage opening stand in and in the section receiving the branch line a vented Lubricating oil collection container leading overflow pipe empties. By the subdivision of the storage tank can be achieved in the section where the overflow pipe does not open, when filling an air cushion is formed that reaches the lubricating oil pressure and therefore ensures that the check valve if normal lubrication fails, it opens and then from the storage tank oil first exits the ring line under pressure.
Vorzugsweise ist das Überlaufrohr bis nahe an die Decke des Vorratstanks hochgezogen. Beim Füllen des Vorratstanks aber auch beim weiteren normalen Betrieb können daher Luftblasen weitgehend über das Überlaufrohr abgeführt werden. Die Luftblasen können daher insbesondere die Notschmierung nicht gefährden.Preferably is the overflow pipe pulled up to the ceiling of the storage tank. When filling the Storage tanks but also during normal operation can therefore Air bubbles largely over the overflow pipe dissipated become. The air bubbles can therefore, in particular, do not endanger emergency lubrication.
