Description

Druckwindkessel für Dampfspeisepumpen, insbesondere für Lokomotiven Gegenstand der Erfindung ist ein Druckwindkessel für Dampfspeisepumpen, insbesondere für Lokomotiven, bei dem Mittel vorgesehen sind, um Wasserschläge in der Druckleitung zu verhüten.Pressure air vessels for steam feed pumps, in particular for locomotives The invention relates to a pressure air vessel for steam feed pumps, in particular for locomotives, in which means are provided to prevent water hammer in the pressure pipe to prevent.

Man hat, um einen möglichst schlagfreien Wasserstrom in der Druckleitung von Pumpen zu erzielen, bereits den Vorschlag gemacht, in dem Druckwindkessel einen Kolben eintubauen und das über dem Kolben befindliche elastische Luftkissen zum Ausgleich der Schläge in der Druckleitung als Puffer zu benutzen.You have to ensure that the water flow in the pressure line is as smooth as possible to achieve by pumps, the proposal has already been made in the pressure air vessel Tubulate the piston and use the elastic air cushion above the piston for the To compensate for the blows in the pressure line to be used as a buffer.

Da sich mit Rücksicht auf die beschränkten Raumverhältnisse bei gewissen Maschinenanlagen, insbesondere bei Lokomotiven, die Anordnung eines großen Druckwindkessels verbietet, so besteht die Möglichkeit, daß sich bei einem Druckwindkessel mit der angedeuteten Einrichtung der über dem Kolben befindliche Luftvorrat durch Undichtigkeit des Kolbens allmählich erschöpft oder doch so stark vermindert, daß der Zweck der Einrichtung nur mangelhaft oder gar nicht erfüllt wird.Because with consideration of the limited space available with certain Machine systems, especially in the case of locomotives, the arrangement of a large pressure air vessel forbids, there is the possibility that with a pressure air tank with the indicated facility of the air supply located above the piston due to leakage of the piston gradually exhausted or at least so greatly diminished that the purpose of the Establishment is poorly or not at all fulfilled.

Dagegen Abhilfe zu schaffen, ist der Zweck der Erfindung.To remedy this is the purpose of the invention.

Dieser Zweck wird erfindungsgemäß. dadurch erreicht, daß der Raum, der sich über dem im Druckwindkessel angeordneten Kolben befindet, mit einem Druckluftbehälter-beiLokomotiven mit dem für die Druckluftbremseinrichtung vorgesehenen Hauptluftbehälter - in Verbindung gebracht wird, so daß über dem Kolben stets eine bestimmte Menge Druckluft von bestimmter Spannung vorhanden ist.This purpose is in accordance with the invention. achieved by the fact that the space which is located above the piston arranged in the pressure air vessel, with a compressed air tank - for locomotives with the main air reservoir provided for the compressed air brake device - in connection is brought so that over the piston always a certain amount of compressed air of certain Voltage is present.

Der Erfindungsgegenstand ist auf der Zeichnung schematisch veranschaulicht.The subject of the invention is illustrated schematically in the drawing.

Die Abbildung stellt einen senkrechten Längsschnitt durch einen gemäß der Erfindung ausgerüsteten Druckwindkessel dar.The figure shows a vertical longitudinal section through an according to the invention equipped pressure air vessel.

a ist der zylindrische Druckwindkessel, in dem sich der Kolben b befindet; der über dem Kolben b befindliche Raum des Windkessels steht durch ein oben an den Windkessel sich anschließendes Rohr mit dem Hauptluftbehälter der Lokomotive in Verbindung. In die Verbindung wird zweckmäßig ein zum Windkessel hin sich öffnendes Rückschlagventil c angeordnet.a is the cylindrical pressure vessel in which the piston b is located; the space of the air chamber located above the piston b is connected to the top by a Air chamber connecting pipe with the main air tank of the locomotive in Link. In the connection there is expediently an opening towards the air chamber Check valve c arranged.
