Description

Einrichtung zum Anlassen und Überwinden g@ßer Saughöhen an ortsbeweglichen Pumpen für Feuerlösch:: und ähnliche Zwecke Die Erfindung betrifft eine ortsbeweglich Pumpe für Feuerlösch- und ähnliche Zu-ecke, an deren Saugrohrende zum Anlassen und Überwinden großer Saughöhen eine besondere Anlaß- bzw. Hilfspumpe angeordnet ist, die durch eine Flüssigkeits- od°r Luftturbine angetrieben wird, deren Treibmittel von einer besonderen Treibmittelpumpe geliefert wird.Device for starting and overcoming large suction heights on portable Pumps for fire extinguishing and similar purposes The invention relates to a portable Pump for fire extinguishers and the like, at the end of the suction tube for starting and A special starting or auxiliary pump is arranged to overcome large suction heights, which is driven by a liquid or air turbine, its propellant is supplied by a special propellant pump.

Bei den bisher bekannten Einrichtungen dieser Art tritt das Treibmittel nach Durchströmen der Turbine in die von der Pumpe geförderte Flüssigkeit aus. Man kann daher in solchen Einrichtungen nur Treibmittel verwenden, deren Verlust wirtschaftlich tragbar und deren Beimengung zu Feuerlöschflüssigkeiten angängig ist. Solche Treibmittel, also hauptsächlich Wasser, führen aber bisweilen Unreinlichkeiten mit sich und können daher für Feuerlöschpumpen nicht verwendet werden, da diese ohne lange Vorarbeiten sofort zur Förderung bereit sein müssen. Die Verwendung ölhaltiger Treibmittel ist wegen der Feuergefährlichkeit ausgeschlossen.In the previously known devices of this type, the propellant occurs after flowing through the turbine into the liquid delivered by the pump. Man can therefore only use propellants in such facilities, the loss of which is economical portable and their admixture to fire extinguishing fluids is acceptable. Such propellants so mainly water, but sometimes carry impurities with them and can therefore cannot be used for fire extinguishing pumps, as they do not require long preparatory work must be ready for funding immediately. The use of oily propellants is excluded because of the fire hazard.

Diese Nachteile sind gemäß der Erfindung dadurch behoben, daß das Treibmittel nach seiner Arbeitsleistung in der Flüssigkeits-oder Luftturbine wieder zu der auf der Welle der Hauptpumpe sitzenden Treibmittülputnpe zurückgeführt wird. Dadurch wird z. B. die Verwendung von öl als Treibmittel möglich, das nicht einfriert, so daß auch bei Frost die Pumpe betriebsfähig bleibt.These disadvantages are eliminated according to the invention in that the Propellant again after its work in the liquid or air turbine is returned to the propellant pump located on the shaft of the main pump. This z. B. the use of oil as a propellant is possible, which does not freeze, so that the pump remains operational even in frosty conditions.

Die Zeichnung zeigt schematisch .ein Ausführungsbeispiel der Erfindung.The drawing shows schematically an embodiment of the invention.

Auf der Welle B der Hauptpumpe A ist der Läufer der Treibmittelpumpe D aufgekeilt. Diese Pumpe D drückt das ihr durch die Leitung 0 zugeführte Treibmittel (z. B. 01 ) durch den Schlauch E in die Turbine F, die im Saugkorb h der Pumpe A liegt und die Hilfs- bzw. Anlaßpumpe H antreibt. Aus der Turbine F fließt das Treibmittel durch die Leitung G wieder vor die Saugseite der Treibmittelpumpe D.The rotor of the propellant pump D is keyed on the shaft B of the main pump A. This pump D pushes the propellant supplied to it through the line 0 (e.g. 01) through the hose E into the turbine F, which is located in the suction strainer h of the pump A and drives the auxiliary or starting pump H. The propellant flows from the turbine F through the line G again upstream of the suction side of the propellant pump D.

Das Ein- und Ausschalten der Turbine F zum Ingangsetzen oder Stillsetzen der Hilfs-bzw. Anlaßpumpe H erfolgt durch Schließen bzw. öffnen des Absperrgliedes J in der Umgehungsleitung C, welche die Leitungen L und G miteinander verbindet, so daß bei geöflnetem Absperrglied f das Treibmittel ohne Arbeitsleistung von der Druckseite der Treibmittelpumpe D unmittelbar zur Saugseite zurückfließen kann.Switching the turbine F on and off for starting or stopping the auxiliary or. Starting pump H takes place by closing or opening the shut-off element J in bypass line C, which connects lines L and G to one another, so that when the shut-off member f is open the propellant without any work from the Pressure side of the propellant pump D can flow back directly to the suction side.
