Description
DEUTSCHESGERMAN
Die Erfindung betrifft eine Einrichtung zur Überwachung der Temperatur von Axialdrucklagern, insbesondere bei Turbomaschinen.The invention relates to a device for monitoring the temperature of thrust bearings, in particular in turbo machines.
Üblicherweise werden die Temperaturfühler in dem aus dem Axial drucklager abfließenden Schmierölstrom angeordnet. Sie überwachen sowohl die Ölversorgung als auch den Zustand des Lagers, d. h. die Belastung des Lagers; denn dieses antwortet bei Störungen, insbesondere bei unzulässigem Schub, mit einer Erhöhung der ölaustrittstemperatur, die dann von dem Temperaturfühler im Gefahrenfall durch Hör- oder Leuchtmelder angezeigt wird. Es ist als wichtig bekannt, die öltemperatur an der richtigen Stelle zu messen, d. h. sie nicht etwa nur in der ölablaufsammelleitung des Lagers (denn hierdurch strömt im allgemeinen auch die aus dem Traglager ausfließende ölmenge, und diese verdeckt die Erwärmung des aus dem Drucklager austretenden Öls), sondern vielmehr unmittelbar in dem von dem Drucklager-Wellenbund abfließenden ölstrom zu messen.The temperature sensors are usually located in the lubricating oil flow flowing out of the thrust bearing arranged. They monitor both the oil supply and the condition of the bearing, i. H. the Load on the bearing; because this responds in the event of malfunctions, especially in the case of impermissible thrust an increase in the oil outlet temperature, which is then triggered by the temperature sensor in the event of danger Hearing or indicator light is displayed. It is known to be important to keep the oil temperature at the correct one Place to measure, d. H. not only in the oil drain manifold of the bearing (because this generally also causes the amount of oil flowing out of the support bearing to flow, and this hides the heating of the oil emerging from the thrust bearing), but rather directly in that of the thrust bearing shaft collar to measure the outflowing oil flow.
Die Erfindung will die Temperaturkontrolle noch empfindlicher, noch genauer machen. Sie will die Temperatur unmittelbar an der Stelle der Erwärmung, nämlich am Ölfilm des Drucklagers messen. Sie besteht darin, daß der oder die Temperaturfühler an der Gleitfläche mindestens eines der Segmente des Lagers, vorzugsweise an der Austrittskante, eingebaut ist bzw. sind.The invention aims to make temperature control even more sensitive, even more precise. She wants the temperature Measure directly at the point of heating, namely on the oil film of the thrust bearing. she consists in that the temperature sensor or sensors on the sliding surface of at least one of the segments of the bearing, is or are preferably installed at the trailing edge.
Die Zeichnung zeigt ein Ausführungsbeispiel des Gegenstandes der Erfindung in axialem Längsschnitt.The drawing shows an embodiment of the subject matter of the invention in axial longitudinal section.
An der Austrittskante des Segments ist ein thermoelektrisches Element 1 eingebaut, welches die Ölfilmtemperatur an dieser Stelle aufnimmt. Der im Element 1 entstandene elektrische Impuls wird im Elektronenverstärker 2 verstärkt und auf den Temperaturanzeiger 3, das Signalgerät 4 und das die Abschaltvorrichtung beherrschende Organ 5 übertragen. Das Organ 5 kann z. B. ein Ventil im ölsysteni des Sicherungsgeräts sein.A thermoelectric element 1 is installed at the trailing edge of the segment, which determines the oil film temperature records at this point. The electrical impulse generated in element 1 is in the Amplifier 2 amplified and on the temperature indicator 3, the signaling device 4 and the shutdown device Controlling body 5 transferred. The organ 5 can, for. B. a valve in the oil system Be a belay device.
Der Temperaturanzeiger 3 überwacht unmittelbar die Temperatur des Ölfilms unter dem Segment. Sobald eine Temperatur von etwa 95° C angezeigt wird, macht das Signalgerät 4 die Bedienungsperson auf die unzulässige Temperaturerhöhung aufmerksam. Zwecks vollkommener Sicherung wird beim Erreichen einer Temperatur von etwa 105° C das die Abschaltvorrichtung beherrschende Organ 5 ausgelöst.The temperature indicator 3 directly monitors the temperature of the oil film under the segment. As soon a temperature of about 95 ° C is displayed, the signal device 4 makes the operator on the inadmissible temperature increase attentively. For the purpose of complete security, when a Temperature of about 105 ° C triggered the shut-off device dominating organ 5.
Auf diese Weise wird die Funktion des Achslagers im Laufe des Betriebes gesichert und überwacht.In this way, the function of the axle bearing is secured and monitored during operation.
Das winzige Thermoelement 1 ist also ein Mittel, die Temperaturmessungen direkt am Ort der Ursache Einrichtung zur ÜberwachungThe tiny thermocouple 1 is therefore a means of taking temperature measurements directly at the location of the cause Monitoring device
