Die bis jetzt bekannt gewordenen Pumpensysteme mit hydraulischem Gestänge, welche mit einem Differentialkolben für die Saugepumpe und nur einem Verbindungsrohr zwisehen Saugepumpe und Antriebspumpe arbeiten sollten, zeigten in der Praxis den großen Nachteil, daß die Bewegung des Differentialkolbens eine sehr schwere war, ein großer Kraftaufwand erforderlich wurde und nur mitThe so far known pump systems with hydraulic linkage, which with a differential piston for the suction pump and only one connecting pipe Suction pump and drive pump should work, showed in practice the great disadvantage that the movement of the differential piston was a very heavy one, a great effort was required and only with
ίο einer sehr geringen Hubzahl gearbeitet werden konnte. Der Nutzeffekt solcher Pumpen wurde dadurch naturgemäß sehr beeinträchtigt.ίο a very low number of strokes can be used could. The efficiency of such pumps was naturally very impaired.
'Bei der vorliegenden Erfindung kommt eine Antriebspumpe (Kolbenpumpe oder rotierende Pumpe oder andere Pumpe) zur Anwendung, deren Umdrehungszahl unabhängig von der Hubzahl . des Differentialkolbens der Saugepumpe ist. Diese Antriebspumpe ist so angeordnet, daß ein von der Pumpenwelle zwangläufig gesteuertes Dreiwegeventil abwechselnd einerseits das Druckwasser zwischen den Differentialkolben der Saugepumpe treten läßt und andererseits das geförderte Wasser mit dem Druckwasser durch einen Saugestutzen der Antriebspumpe zuführt.In the present invention, a drive pump (piston pump or rotating Pump or other pump) are used whose number of revolutions is independent of the Stroke rate. of the differential piston of the suction pump. This drive pump is arranged in such a way that that a three-way valve positively controlled by the pump shaft alternately on the one hand the pressurized water between the differential pistons the suction pump and on the other hand the pumped water with the pressurized water through a suction nozzle the drive pump supplies.
Die Zeichnung zeigt die neue Pumpe in einem Ausführungsbeispiel, und zwar ist gedacht, daß aus einem entfernt von der Antriebsstation liegenden Rohrbrunnen Wasser nach einem Hochbehälter gefördert werden soll.The drawing shows the new pump in an embodiment, and that is intended that water is conveyed to an elevated tank from a pipe well located at a distance from the drive station target.
Der Ventilkolben b der Sauge- und Hebepumpe ist durch das Gestänge α mit dem oberen Kolben c größeren Querschnitts zu einem Differentialkolben starr verbunden, und es steht der Zwischenraum zwischen b und c mit der Antriebspumpe durch das Rohr d in Verbindung. Die Antriebspumpe i ist mit dem Saugwindkessel, e. und dem Druckwindkessel f versehen. Beide Windkessel stehen 4" miteinander und mit der Hauptpumpe durch den Dreiwegehahn g und die anschließenden Rohrleitungen 0, k, d in Verbindung. Der Druckwindkessel f hat außerdem einen zweiten Auslaßstutzen, welcher mit dem Steigerohr m. unter Zwischenschaltung des Drosselventils h in Verbindung steht. Das Dreiwegeventil g wird durch eine Hebelübertragung r, welche mittels Kurvenentführung in bekannter Weise arbeitet, durch die Pumpenwelle selbst bewegt. Dabei macht das Dreiwegeventil abwechselnd je eine Vierteldrehung, wobei es hubweise die Verbindung zwischen der Rohrleitung d und Druckwindkessel f und andererseits zwischen d und dem Saugwindkessel e herstellt. Die Hubzahl des Dreiwegeventils wird in bekannter Weise durch Räderübersetzung p, q herabgemindert, weil in den meisten Fällen die Tourenzahl der Antriebspumpe weit größer als die Hubzahl der Saugepumpe ist.The valve piston b of the suction and lifting pump is rigidly connected by the linkage α to the upper piston c of larger cross-section to form a differential piston, and the space between b and c is connected to the drive pump through the pipe d . The drive pump i is connected to the suction air tank, e. and the pressure air vessel f . Both air tanks are 4 "with each other and with the main pump through the three-way valve g and the connecting pipes 0, k, d . The pressure air tank f also has a second outlet connection which is connected to the riser pipe m. With the interposition of the throttle valve h . The three-way valve g is moved by the pump shaft itself by means of a lever transmission r, which works in a known manner by means of cam removal. The three-way valve alternately makes a quarter turn, whereby it lifts the connection between the pipeline d and the pressure vessel f and on the other hand between d and the suction air produces e. the number of strokes of the three-way valve is p in a known manner by wheels translation, q diminished because in most cases, the number of revolutions of the drive pump is much greater than the stroke of the suction pump.
Die Wirkungsweise ist folgende: .The mode of action is as follows:.
In Fig. ι und 2 zeigt das Dreiwegeventil g die Verbindung mit dem Druckwindkessel f und dem Differentialkolben b, c, wobei das im Druckwindkessel f angesammelte Druckwasser den Differentialkolben hebt. Die Antriebspumpe i saugt inzwischen den Saugwindkessel e leer und erzeugt darin eine Luftverdünnung. Fig. 3 zeigt das Dreiwegeventil in seiner zweiten Stellung. Es sperrt hierbei den Druckwindkessel f gegen den Differentialkolben ab und gibt die Verbindung zwischen dem Dif-In Fig. 1 and 2, the three-way valve g shows the connection with the pressure air vessel f and the differential piston b, c, the pressurized water accumulated in the pressure air vessel f lifting the differential piston. The drive pump i meanwhile sucks the suction air tank e empty and generates an air dilution in it. Fig. 3 shows the three-way valve in its second position. It blocks the pressure air vessel f from the differential piston and provides the connection between the differential
ferentialkolben und dem Saugwindkessel e- frei. Das Wasser tritt jetzt in den Saugwindkessel e ein, und der Differentialkolben sinkt herab, welcher Vorgang durch die im Saugwindkessel e erzeugte Luftverdünnung sehr beschleunigt wird. Während dieser Arbeit hat die Antriebspumpe i im Druckwindkessel f einen erhöhten Druck erzeugt, wodurch das geförderte Wasser durch das Drosselventil h nach derferential piston and the suction air tank e- free. The water now enters the suction air vessel e and the differential piston sinks, which process is greatly accelerated by the dilution of the air produced in the suction air vessel e. During this work, the drive pump i has generated an increased pressure in the pressure air tank f , whereby the pumped water through the throttle valve h after the
ίο Verbrauchsstelle gedruckt wird. Das Drpsselventil h ist durch Federn oder Gewichte entsprechend dem zum Hochheben des Differentialkolbens nötigen Druck belastet. Dadurch, daß im Druckwindkessel f ein erhöhter Druck erzeugt wird, erfolgt nach Öffnung des Dreiwegeventils g ein schnelles Hochgehen des Differentialkolbens ohne Rückstoß auf die Antriebspumpe. Die Bewegung des Differentialkolbens wird also durch die Druckwirkung von f und die Saugewirkung von e sehr erleichtert und der Nutzeffekt des ganzen Pumpenwerkes dadurch sehr erhöht.ίο Consumption point is printed. The throttle valve h is loaded by springs or weights corresponding to the pressure required to lift the differential piston. Characterized in that f in the pressure surge tank, an elevated pressure is generated, takes place after opening of the three-way valve g rapid high Go of the differential piston without impact to the drive pump. The movement of the differential piston is thus greatly facilitated by the pressure effect of f and the suction effect of e , and the efficiency of the entire pump mechanism is thereby greatly increased.
