Die Vorrichtung soll bei Luftpumpen, die von der Hauptmaschine aus angetrieben werden, zur Anwendung kommend, verhindern, daß beim Stillstande der Hauptmaschine die Luftpumpe sich mit dem im Kondensator noch niedergeschlagenen Wasser füllt und dann beim Angehen der Hauptmaschine Schaden erleidet, indem die Querschnitte in den Ventilen für den Durchlaß einer dasThe device is intended for air pumps that are driven by the main engine, come into use, prevent the Air pump fills up with the water still precipitated in the condenser and then when the main engine starts up Suffers damage by the cross-sections in the valves for the passage of a das
ίο Vielfache des gewöhnlich durchgepumpten Quantums betragenden Wassermenge nicht ausreichen.ίο Multiples of what is usually pumped through Quantum's amount of water is not sufficient.
Entsprechende Vorrichtungen, welche verhindern sollen, daß beim Stillstande der Hauptmaschine der Niederdruckzylinder sich mit Wasser aus dem Kondensator fülle, sind bereits bekannt. Sie bestehen darin, daß das Vakuum des Kondensators beim Anhalten derAppropriate devices, which should prevent that when the standstill The main engine is the low-pressure cylinder filling with water from the condenser already known. They consist in that the vacuum of the condenser when stopping the
. Maschine zerstört wird, indem ein Abschlußorgan Luft in das Abdampfrohr eintreten läßt.. Machine is destroyed by a closing device air entering the exhaust pipe leaves.
Bei der vorliegenden Vorrichtung findet jedoch ein Zerstören des Vakuums nicht statt. Die Vorrichtung besteht vielmehr darin, daß die Luftpumpe a, verbunden mit dem Kondensator b durch ein weites Dampfabsaugerohr c, welches vom oberen Teil des Kondensators ausgeht, und ein enges Wasserabsaugerohr d, welches vom tiefsten Punkte des Kondensators ausgeht und vor dem Saugeventil der Luftpumpe sich mit dem Dampfabsaugerohr c vereinigt, abgesperrt werden kann beim Stillstände der Hauptmaschine gegen den Wasserzufluß aus dem Kondensator durch ein Absperrorgan (Hahn, Schieber usw.) e, welches, im Wasserabsaugerohr d eingebaut, durch einen Zug f vom Maschinistenstande aus bewegt werden kann.In the case of the present device, however, there is no destruction of the vacuum. The device is rather that the air pump a, connected to the condenser b by a wide steam suction pipe c, which extends from the upper part of the condenser, and a narrow water suction pipe d, which extends from the lowest point of the condenser and is in front of the suction valve of the air pump Combined with the steam suction pipe c , it can be shut off when the main engine is at a standstill against the flow of water from the condenser by a shut-off device (tap, slide valve, etc.) e, which, installed in the water suction pipe d , can be moved by a train f from the machinist.
Fig. ι zeigt den Querschnitt der Hauptmaschine mit Luftpumpe, Kondensator und der Vorrichtung.Fig. Ι shows the cross section of the main machine with air pump, condenser and the device.
Beim Stillstande der Hauptmaschine schließt der Maschinist das Absperrorgan e und öffnet es erst wieder nach dem Ingangsetzen der Maschine, so daß jetzt das angesammelte Kondenswasser in die Luftpumpe fließt und von dieser mit weggepumpt wird.At standstill the main engine of the machine operator closes the shut-e and opens it again only after starting the machine, so that now the accumulated condensation flows into the air pump and is pumped away from this with.
Die Vorrichtung kann auch so angeordnet werden, daß das Absperrorgan e durch Zug in der Art mit der Umsteuerwelle der Hauptmaschine verbunden wird, daß, wenn die Umsteuerwelle auf Halt steht, das Absperrorgan geschlossen ist, während es geöffnet ist in der Vorwärts- und Rückwärtsstellung der Umsteuerwelle (Fig. 2).The device can also be arranged so that the shut-off element e is connected to the reversing shaft of the main engine by train in such a way that when the reversing shaft is on hold, the shut-off element is closed while it is open in the forward and reverse positions Reversing shaft (Fig. 2).
