Description
Druckventillose Kolbenpumpe. Die Erfindung bezieht sich auf druckventillose Kolbenpumpen, bei denen durch die Trägheit einer in Bewegung befindlichen Flüssigkeitssäule Flüssigkeit gefördert wird, und besteht darin, daß zwecks Erzielung eines stoßfreien Ganges und einer erhöhten Förderleistung der Pumpe hinter den Antrieb, aber vor die Druckwassersäule ein elastisches Organ eingeschaltet ist, welches derart ausgebildet ist, daß die während der Beschleunigungsperiode des Kolbens infolge der Zusaminendrückung aufgespeicherte Arbeit bis zum Ende der Verzögerungsperiode infolge der hierbei auftretenden Ausdehnung vollkommen abgegeben wird, und welches Organ während des ganzen Saughubes unwirksam bleibt. Durch den schnellaufenden Kolben wird die Fördersäule ganz oder zum Teil elastischen Hebeimpulsen ausgesetzt, die in ihrer Zahl und Stärke so bemessen sind, daß clie während der Hebeimpulse in Bewegung versetzte F lüssigl:eitssäule eine so große Geschwindigkeit erreicht, daß sie in den zwischen den aufeinanderfolgenden Hebeimpulsen liegenden kurzen Zeiträumen nicht in die Anfangslage zurücksinken kann.Piston pump without pressure valves. The invention relates to non-pressure valves Piston pumps, in which by the inertia of a moving column of liquid Liquid is conveyed, and is that in order to achieve a shock-free Ganges and an increased delivery rate of the pump behind the drive, but in front the pressurized water column is turned on an elastic organ which is designed in this way is that during the acceleration period of the piston due to compression accumulated work until the end of the delay period as a result of this occurring expansion is completely released, and which organ during the entire suction stroke remains ineffective. The pumping column is driven by the high-speed piston wholly or partly exposed to elastic lifting impulses, which in their number and strength are dimensioned so that the liquid column set in motion during the lifting impulses reaches such a great speed that it is in between the successive Lifting impulses lying short periods of time can not sink back into the initial position.
Die Zeichnung veranschaulicht beispielsweise Ausführungsformen des Erfindungsgegenstandes in schematischer Darstellung.The drawing illustrates, for example, embodiments of the Subject of the invention in a schematic representation.
Bei der in Abb. i dargestellten Ausführungsform der Pumpe ist zwischen dem den Pumpenkolben i enthaltenden Pumpenzylinder 2 und der Druckleitung 3 eine Membran .I angeordnet, die gemeinsam mit einer siebartigen Unterlage 5 das Innere eines Druckwindkessels 6 gegen das Innere der Pumpe abschließt. Zum Flüssigkeitseinlaß dient ein Saugventil 7. Wenn der Kolben i in rasche hin und her gehende Bewegung versetzt wird, so preßt er die im Zylinder 2 befindliche Wassermenge in das Druckrohr 3, in dem die Wassersäule beschleunigt wird, wobei die Membran ¢ nachgibt und dadurch das Auftreten von Stößen verhindert. Die in Bewegung versetzte Wassersäule setzt ihren Weg auch nach Erreichung der Totpunktlage des Kolbens und während des Kolbenrücklaufes fort, und da die siebartige Unterlage 5 ein Nachgeben der unter Luftdruck stehenden Membran verhindert, entsteht ein Unterdruck, der zur Folge hat, daß sich das Saugventil 7 öffnet und von unten Wasser einströmt. Sobald der Unterdruck aufhört und der Kolben seine Vorwärtsbewegung beginnt, wird wieder Flüssigkeit in das Druckrohr gefördert und die Drucksäule in Bewegung versetzt.In the embodiment of the pump shown in Fig. I is between the pump cylinder 2 containing the pump piston i and the pressure line 3 a Membrane .I arranged, which together with a sieve-like base 5, the interior a pressure air vessel 6 against the interior of the Pump completes. A suction valve 7 is used for the liquid inlet. When the piston i swiftly back and forth moving movement is offset, so he presses the amount of water in the cylinder 2 into the pressure pipe 3, in which the water column is accelerated, the membrane ¢ yields, thereby preventing bumps from occurring. That set in motion Water column continues its way even after reaching the dead center position of the piston and continues during the piston return, and since the sieve-like base 5 gives way prevented by the pressurized membrane, a negative pressure is created that leads to The result is that the suction valve 7 opens and water flows in from below. As soon the negative pressure stops and the piston starts moving forward again Liquid conveyed into the pressure pipe and the pressure column set in motion.
Bei der in Abb. 2 dargestellten Ausführungsform fehlt der Windkessel, und es ist bloß eine Membran 8 vorgesehen, die aus federndem Wellblech bestehen kann, um eine genügende Widerstandskraft ausüben zu können.In the embodiment shown in Fig. 2, the air chamber is missing, and only a membrane 8 is provided, which consist of resilient corrugated sheet metal can in order to be able to exert sufficient resistance.
Bei der in Abb. 3 dargestellten Ausführungsform ist statt der Membran ein Kolben g vorgesehen, der in einem Druckzylinder io beweglich ist und dessen Rückbewegung mittels eines Anschlags i i begrenzt ist.In the embodiment shown in Fig. 3, instead of the membrane a piston g is provided which is movable in a pressure cylinder io and its Return movement is limited by means of a stop i i.
Die in Abb.4 dargestellte Ausführungsform zeigt einen Kolben 12, der unter der Einwirkung einer Feder 13 steht und dessen Hub durch Anschläge 14 begrenzt ist.The embodiment shown in Figure 4 shows a piston 12 which is under the action of a spring 13 and whose stroke is limited by stops 14.
Abb. 5 zeigt eine Pumpe, in deren Druckraum sich ein elastisch zusammendrückbarer Körper, z. B. ein von einer undehnbaren Hülle 15 umgebener Gummiball, befindet, der mit Druckluft gefüllt ist.Fig. 5 shows a pump in whose pressure chamber an elastically compressible one Body, e.g. B. a rubber ball surrounded by an inextensible cover 15 is located, which is filled with compressed air.
Abb. 6 stellt eine Pumpe dar, deren hohler Kolben 16 als Druckwindkessel ausgebildet ist, wobei die Membran 17 und die siebartige Unterlage 18 genau so wirken, wie die Membran q und die siebartige Unterlage 5 nach Abb. i.Fig. 6 shows a pump, the hollow piston 16 of which is used as a pressure air vessel is formed, wherein the membrane 17 and the sieve-like base 18 act in exactly the same way, like the membrane q and the sieve-like base 5 according to Fig. i.
Abb. 7 zeigt eine Ausführungsform, bei welcher der Kolben i g gegenüber der Kolbenstange 2o verschiebbar ist, wobei eine Feder 2i ein nachgiebiges Zurückweichen des Kolbens ig ermöglicht.Fig. 7 shows an embodiment in which the piston i g opposite of the piston rod 2o is displaceable, with a spring 2i resiliently retreating of the piston ig allows.
