Description

Antrieb von Hilfsmaschinen bei Auspufflokomotiven durch eine mit Abdampf betriebene Kondensationskraftmaschine Beim Gegenstand des Hauptpatents wird das von der Kesselspeisepumpe geförderte Speisewasser nach seinem Durchgang durch den Kondensator restlos dem Lokomotivkessel zugeführt. Bei geringer Leistung der Lokomotive kann @es, daher vorkommen, daß die zur Kesselspeisung benötigte, von der Pumpe geförderte Wassermenge zur Aufrechterhaltung des Vakuums im Kondensator nicht ausreicht.' Wenn auch. bei abnehmender Leistung die Dampflieferung zur Abdampfturbine geringer und daher auch weniger Wasser zur Kondensation der geringeren Dampfmenge erforderlich ist, sind. die Wirkungsgrade der Pumpe und der Turbine bei wesentlichen Leistungsverminderungen so viel schlechter, daß das Verhältnis der Dampfmenge zur Wassermenge größer wird. Es handelt sich also nicht allein darum, aus wirtschaftlichen Gründen ein gutes Vakuum im Kondensator aufrechtzuerhalten, sondern bei geringerer Leistung überhaupt den Kondensationsbetrieb der Hilfsmaschinen durchzuführen.Drive of auxiliary machines in exhaust locomotives by one with exhaust steam operated condensation engine The subject of the main patent is that Feed water delivered by the boiler feed pump after it has passed through the Condenser completely fed to the locomotive boiler. When the locomotive has little power @es, therefore it can happen that the one required for the boiler feed is conveyed by the pump The amount of water is insufficient to maintain the vacuum in the condenser. ' if even. with decreasing power, the steam delivery to the exhaust turbine is lower and therefore less water is required to condense the smaller amount of steam is, are. the efficiency of the pump and the turbine with significant reductions in output so much worse that the ratio of the amount of steam to the amount of water increases. So it's not just about a good one for economic reasons Maintain vacuum in the condenser, but at lower power at all to carry out the condensation operation of the auxiliary machines.

Zu diesem Zweck wird ,erfindungsgemäß die Leitung zwischen Kondensator und Kessel mit einem Ventil und einer Rückführleitung zum Tender versehen, so daß durch die Speisepumpe immer eine genügende Kühlwassermenge durch den Kondensator hindurchgepumpt und die für die Kesselspeisung nicht benötigte Menge zum Tender zurückgepumpt wird. Wenn dadurch auch für die Abdampfturbine ein etwas höherer Leistungsbedarf notwendig ist, so ist dies nicht sehr wesentlich, da stets genügend Abdampf der Lokomotivmaschine vorhanden ist.For this purpose, according to the invention, the line between the capacitor and boiler provided with a valve and a return line to the tender so that With the feed pump, there is always a sufficient amount of cooling water through the condenser pumped through and the amount not required for the boiler feed to the tender is pumped back. Even if this results in a somewhat higher power requirement for the exhaust steam turbine is necessary, this is not very essential, as there is always enough exhaust steam Locomotive engine is present.

Auf der Zeichnung ist ein. Ausführungsbeispiel der Erfindung schematisch veranschaulicht.On the drawing is a. Embodiment of the invention schematically illustrated.

Der als Kondensationsmaschine ausgebildeten Abdampfturbinee wird Abdampf durch eine Leitung o zugeführt. Die Turbine e treibt die K esselspeisepumpe f, die durch -eine Leitung k Wasser aus dem Lokomotivtender d ansaugt und mittels einer Leitung l durch den Kondensator i der Turbine e hindurchdrückt und dann mittels eines Rohres dem Speisedom b des Lokomotivkessels zuführt. In das Rohr m ist ein Dreiwegehahn m' o. dgl. eingeschaltet, der mittels eines Gestänges m2p vom Führerstand der Lokomotive aus gesteuert werden kann. An dem Dreiwegehahn ist ein Rohrs angeschlossen, das entweder unmittelbar in den Tender führt oder an die das Kondensat zum Tender führende Leitung r angeschlossen ist. In die Leitung s wird zweckmäßig ein Rückschlagventileingeschaltet.The exhaust steam turbine, which is designed as a condensation machine, becomes exhaust steam fed through a line o. The turbine e drives the boiler feed pump f, the through a line k sucks water from the locomotive tender d and by means of a Line l pushes through the condenser i of the turbine e and then by means of a pipe feeds the feed dome b of the locomotive boiler. In the tube m is a Three-way cock m 'or the like switched on, which by means of a linkage m2p from the driver's cab the locomotive can be controlled from. A pipe is connected to the three-way valve, that either leads directly to the tender or to which the condensate goes to the tender leading line r is connected. A check valve is expediently switched on in line s.

Im normalen Betrieb ist die Leitung s durch den Dreiwegehalm ml- von der Leitung m abgeschlossen. Sinkt die Leistung der Lokomotive und damit die erforderliche Menge an Speisewasser, so wird der Dreiwegehahn mittels des Gestänges m2p so weit verstellt, daß dem Kessel nur die erforderliche Wassermenge durch das Rohr m zugeführt wird, die von der Pumpet gelieferte überschießende Wassermenge aber durch das Rohrs in den Tender zurückfließt. Auf diese Weise gelingt ,es, im Kondensator i ein genügendes Vakuum beizubehalten.In normal operation, the line s is through the Dreiwegehalm ml- of the line m completed. The performance of the locomotive drops and thus the required Amount of feed water, the three-way valve is opened by means of the m2p linkage adjusted that the boiler only supplied the required amount of water through the pipe m the excess amount of water delivered by the Pumpet through the pipe flows back into the tender. In this way it is possible to achieve a sufficient result in the capacitor i Maintain vacuum.
