PATENTAMT.PATENT OFFICE.
Die Verbindung zweier einfachwirkenden Kolbenpumpen zu einer doppeltwirkenden Pumpe bezweckt hauptsächlich, daß beim Hubwechsel das Wasser vor den Saugventilen nicht zum Stillstand kommt, sondern an ihnen vorbeiströmt und im Saugwindkessel aufgefangen wird.The connection of two single-acting piston pumps to one double-acting The main purpose of the pump is to ensure that the water in front of the suction valves when the stroke is changed does not come to a standstill, but flows past them and caught in the suction air vessel will.
Bei bekannten Kolbenpumpen kommt das angesaugte Wasser in VerbindungskanälenIn known piston pumps, the water that is sucked in comes into connection channels
ίο oder Eintauchrohren von dem Saugwindkessel oder Saugrohr bis zu den Saugventilen während des Betriebes abwechselnd zur Ruhe und stößt infolge Beschleunigung desselben beim Hubwechsel der Pumpen gegen die Saugventile, welches namentlich beim Schnellauf Wasserschläge verursacht.ίο or immersion pipes from the suction air vessel or suction pipe to the suction valves alternately to rest and during operation hits the suction valves as a result of its acceleration when the pumps change stroke, which especially causes water hammer when running at high speed.
Dagegen sind bei der neuen doppeltwirkenden Pumpe die Saugventile ohne Verbindungskanäle im Saugrohr einander gegenüber vor- gesehen und das Saugrohr selbst in der Richtung der Wasserströmung weiter zu einem Saugwindkessel ausgebildet, so daß das beschleunigte Wasser beim Hubwechsel nicht die Saugventile, 'sondern einen Saugwindkessel trifft, wobei selbst beim Schnellauf der Pumpe keine Wasserschläge entstehen.In contrast, with the new double-acting pump, the suction valves are facing each other without connecting channels in the suction pipe. seen and the suction pipe itself continues to one in the direction of the water flow Suction air vessel designed so that the accelerated water does not change the stroke the suction valves, 'but a suction air tank hits, whereby even at high speed the Pump no water hammer.
Diese Erfindung kann bei verschiedenen Pumpenkonstruktionen zur Anwendung kommen und gibt die Zeichnung einige Beispiele.This invention can be used in various pump designs and the drawing gives some examples.
Fig. I zeigt eine doppeltwirkende Ventilkolbenpumpe, bei welcher die Saugventile beider Pumpenseiten in einem Gehäuse ohne Verbindungskanäle gegenüberliegen und das Saugrohr weitergeführt zu einem Saugwindkessel ausgebildet ist.Fig. I shows a double-acting valve piston pump in which the suction valves Both sides of the pump are opposite each other in a housing without connecting channels and that Suction pipe is formed continued to a suction air vessel.
Fig. 2 zeigt eine doppeltwirkende Plungerpumpe, bei welcher sowohl die Saugventile als auch die Druckventile beider Pumpenseiten in einem Gehäuse ohne Verbindungskanäle gegenüberliegen und sich ebenfalls in der Wasserströmungsrichtung direkt oberhalb der Saugventile ein Saugwindkessel befindet.Fig. 2 shows a double-acting plunger pump, in which both the suction valves as well as the pressure valves on both sides of the pump in one housing without connecting channels opposite and also in the direction of water flow directly above the Suction valves a suction air chamber is located.
Fig. 3 zeigt eine doppeltwirkende Plungerpumpe, bei welcher das Verbindungsrohr beider Ventilgehäuse den Saugraum bildet, durch welchen das einströmende Wasser an den Saugventilen vorbei in den oberhalb anschließenden Saugwindkessel gelangt.Fig. 3 shows a double-acting plunger pump in which the connecting pipe Both valve housings form the suction chamber through which the inflowing water passes the suction valves into the suction air chamber above.
