Description

Dampflokomotive mit Kondensation.Steam locomotive with condensation.

Zusatz zum Patent 425734. Addition to patent 425734.

Die Erfindung bezieht sich auf Dampflokomotiven mit Kondensation nach Patent 425734 und bezweckt, die selbsttätige Speisung des Zusatzkessels ohne Zuhilfenahme eines Schwimmers durch eine Pumpe zu ermoglichen. The invention relates to steam locomotives with condensation according to patent 425734 and aims to automatically feed the additional boiler without To enable the aid of a float through a pump.

Auf der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung schematisch veranschaulicht. In the drawing is an embodiment of the subject matter of Invention illustrated schematically.

In einen Dampfdom a1 des Lokomotivkessels A ist eine Querwand a2 dampfdicht eing-esetzt. in welche eine Anzahl dünnwandiger Rohre B eingewalzt oder eingeschweißt sind. Die der Platte a2 abgekehrten Enden der Rohres sind in eine weitere Platte C eingesetzt, die den Deckel eines schalenförmigen Gefäßes D bildet. Die Teile al, a2, B, C, D stellen den vom Dampf und dem Wasser des Lokomotivkessels A beheizten Zusatzkessel dar, dessen Abmessungen im vorliegenden Falle so gewählt sind, daß er eine größere als die für die Zugheizung und die Deckung der Speisewasserverluste jeweils erforderliche Dampfmenge zu liefern vermag. An den Zusatzkessel a1, a2, B, C, D ist die Druckleitung E einer Dampfspeisepumpe F angeschlossen, deren Dampfkolben mit 12 und deren Pumpe. kolben mit fl bezeichnet isr. Die Dampfzuleitung der SpeisepumpeF ist an den Lokomotivkessel a angeschlossen und besitzt ein regelventil g1, das so eingestellt ist, daß die Pumpe beim normalen Betrieb eine Wassermenge in den Zusatzkessel fördert, die den Speisewasserveflusten des Lokomotivkessels entspricht. Die Durchmesser des Dampfkolbeins 12 und des Pumpenkolbensfl sind so bestimmt, daß der zulässige Höchstdruck im Zusatzkessel, der beim Arbeiten der Pumpe F als Gegendruck auf den Pumpenkolben f1 zur Wirkung kommt, dem auf den Dampfkolben f2 wirkenden normalen Druck im Lokomotivkessel das Gleichgewicht hält. Dies hat zur Folge, daß die Pumpe ihre Förderung einstellt, sobald im Zusatzkessel der zulässige Höchstdruck herrscht. In a steam dome a1 of the locomotive boiler A is a transverse wall a2 inserted vapor-tight. into which a number of thin-walled tubes B rolled or are welded. The ends of the tube facing away from the plate a2 are in a Another plate C is used, which forms the lid of a bowl-shaped vessel D. The parts al, a2, B, C, D represent the steam and water of the locomotive boiler A heated additional boiler, the dimensions of which were chosen in the present case are that it is greater than that for train heating and to cover feedwater losses able to deliver the required amount of steam in each case. To the additional boiler a1, a2, B, C, D, the pressure line E of a steam feed pump F is connected to its steam piston with 12 and their pump. piston marked with fl isr. The steam supply line to the feed pump F. is connected to the locomotive boiler a and has a control valve g1, the so is set so that the pump during normal operation a quantity of water in the auxiliary boiler promotes which corresponds to the feedwater flux of the locomotive boiler. The diameter of the steam piston leg 12 and the pump piston are determined so that the permissible Maximum pressure in the auxiliary boiler that can be reached when pump F as counter pressure on the pump piston f1 comes into effect, the one acting on the steam piston f2 normal pressure in the locomotive boiler keeps the equilibrium. This has the consequence that the pump stops its delivery as soon as the maximum permissible pressure in the additional boiler prevails.

Beim normalen Betrieb fördert die Punipe F so viel Wasser in den Zusatzkessel, als den Speisewasserverlusten des Lokomotivkessels entspricht. Sinkt infolge steigender Dampfentnahme der Druck im Zusatzkessel, so steigert auch die Pumpe ihre Leistung, bis der Gleichgewichtszustand wieder erreicht ist. During normal operation, the Punipe F pumps that much water into the Additional boiler than corresponds to the feedwater losses of the locomotive boiler. Sinks as a result of increasing steam extraction, the pressure in the additional boiler also increases Pump their power until equilibrium is reached again.

Steigt umgekehrt nur der Druck im Zusatzkessel, so stellt die Pumpe so lange die Förderung ein, bis das Gleichgewicht wiederhergestellt ist. Steigt dagegen der Druck im Lokomotivkessel, während der Druck im Zusatzkessel konstant bleibt oder sinkt, so beginnt die Pumpe zu fördern, ein Überfluten des Zusatzkessels kann aber trotzdem nicht eintreten, da der Zusatzkessel eine größere Wassermenge zu verdampfen vermag, als die Pumpe ihm zuführen kaum.Conversely, if only the pressure in the additional boiler increases, the pump stops until the balance is restored. Increases on the other hand the pressure in the locomotive boiler, while the pressure in the auxiliary boiler is constant If it remains or falls, the pump begins to deliver, flooding the additional boiler but can still not occur because the additional boiler has a larger amount of water is able to vaporize than the pump can hardly supply it.
