KLASSE 13: Dampfkessel nebst Ausrüstung.CLASS 13: Steam boiler and equipment.
Graf ALBERT de DION,Count ALBERT de DION,
Das charakteristische Merkmal der vorliegenden Einrichtung besteht darin, dafs die Dampf-Öffnung für den Motor der Speisepumpe von einem Punkt des Dampfkessels ausgeht, dessen Höhenlage dem in letzterem zu erhaltenden Niveau entspricht.The characteristic feature of the present device is that the steam opening for the motor of the feed pump starts from a point of the steam boiler, the altitude of which is to be obtained in the latter Level corresponds.
Mittelst der vorliegenden Anordnung wird der genannte Zweck ohne Zuhülfenahme specieller Mechanismen erreicht. Dieselbe ist auf der beiliegenden Zeichnung als Beispiel in der Verbindung einer' kleinen Speisepumpe mit einem Kessel beliebiger Construction veranschaulicht.By means of the present arrangement, the stated purpose becomes more special without assistance Mechanisms achieved. The same is on the accompanying drawing as an example in the link a 'small feed pump with a boiler of any construction.
A ist die direct von einem Motor B getriebene Speisepumpe; die Dampföffnung C des Motors B ist am Kessel G in der Höhe des Normalniveaus MN angebracht. Sobald die Wasserzufuhr seitens der Pumpe stärker ist als die Dampfabgabe von Seiten des Kessels, oder wenn letztere schwächer wird als erstere, so mufs das Wasserniveau notwendigerweise steigen. Wenn es jedoch die Normalhöhe M N überschritten hat, ist der Dampfznflufs nach dem Motor B abgeschnitten, es tritt dann in denselben ein Theil des im Kessel vorhandenen Wasserüberschusses. Die Geschwindigkeit des Motors wird daher wegen der Differenz zwischen der Dichte des Wassers und der des Dampfes geringer und damit die Leistung der Pumpe eine entsprechend schwächere. A is the feed pump driven directly by a motor B; the steam opening C of the motor B is attached to the boiler G at the height of the normal level MN. As soon as the water supply from the pump is greater than the steam output from the boiler, or when the latter becomes weaker than the former, the water level must necessarily rise. If, however , it has exceeded the normal height MN , the steam supply to motor B is cut off, and part of the excess water in the boiler then enters it. The speed of the motor is therefore lower because of the difference between the density of the water and that of the steam, and the pump output is accordingly weaker.
Ferner wird der Motor infolge seiner Lage selbst in eine Pumpe umgewandelt, welche aus dem Kessel so lange Wasser pumpt, bis das Normalniveau wieder hergestellt ist, worauf sodann der Motor von neuem unter der Wirkung des Dampfes functionirt und die Speisung ihren normalen Verlauf nimmt. Das aus dem Kessel gepumpte Wasser fliefst durch Oefmungen im Motor B nach dem Speisekasten D und dient zur Vorwärmung von Speisewasser; sein Volumen wird immer nur ein geringes sein, da bei der geringsten Ueberschreitung des Normalniveaus im Kessel sofort Wasser mit in das Rohr, C gerissen wird.Furthermore, due to its position, the motor itself is converted into a pump which pumps water from the boiler until the normal level is restored, whereupon the motor functions again under the action of the steam and the supply takes its normal course. The water pumped from the boiler flows through openings in motor B to feed box D and is used to preheat feed water; its volume will always be only a small one, since when the normal level in the boiler is even slightly exceeded, water is immediately drawn into the pipe, C.
Die vorstehend beschriebene Einrichtung kann bei jedem stehenden oder liegenden Dampfgenerator angewendet und entweder direct mit demselben verbunden oder in beliebiger Entfernung davon aufgestellt werden.The device described above can be used with any standing or lying steam generator and either directly with it connected to the same or placed at any distance from it.
