Description
Die Erfindung betrifft eine Vorrichtung zum Pumpen großer Fördermengen einer Flüssigkeit, mit mindestens zwei jeweils eine eigene Baueinheit bildenden Pumpen, die druckseitig gemeinsam an eine Druckleitung angeschlossen und an einen gemeinsamen Antrieb gekoppelt sind, wobei die Pumpen derart mit dem Antrieb verkoppelt sind, daß jede von ihnen um ein bestimmtes, feststehendes Zeitintervall versetzt gegenüber den jeweils anderen Pumpen einen Pumphub ausführt.The invention relates to a device for pumping large Flow rates of a liquid, with at least two each a separate unit forming pumps, the pressure side connected together to a pressure line and coupled to a common drive, wherein the Pumps are coupled to the drive so that each from them around a certain, fixed time interval offset from the other pumps one Pumphub performs.
Derartige Pumpen werden beim Prüfen und Reinigen von Pipelines eingesetzt. Zum Prüfen der Pipelines werden diese durch "Stressen" auf Dichtheit geprüft. Dabei wird eine Flüssigkeit, beispielsweise Wasser, unter einem Druck in die Pipelines gepumpt, der höher ist, als das in der Pipeline zu fördernde Medium im Betriebszustand der Pipeline besitzt. Ist die so geprüfte Pipeline bei einem höheren Prüfdruck dicht, so wird davon ausgegangen, daß sie auch im Betriebszustand, bei einem niedrigeren Druck als dem Prüfdruck, dicht ist. Such pumps are used in testing and cleaning of Pipelines used. To check the pipelines these are checked for tightness by "stressing". It will a liquid, such as water, under one Pressure pumped into the pipelines, which is higher than that in The pipeline to be pumped medium in the operating condition of Owns pipeline. Is the pipeline so tested at one higher test pressure tight, it is assumed that They also in the operating condition, at a lower pressure as the test pressure, is tight.
Die Länge des Abschnitts, der während eines Streß-Vorgangs überprüft werden kann, hängt von der Flüssigkeitsmenge ab, die in die Pipeline eingeleitet werden kann. Je größer die Flüssigkeitsmenge, die mit dem gewünschten Druck in die Pipeline gepumpt werden kann, desto größer ist die Länge des Abschnitts, der überprüft werden kann. Je größer die Länge der einzelnen Abschnitte, desto geringer ist die Anzahl der Streß-Vorgänge, die zur Überprüfung eines gegebenen Pipeline-Abschnitts benötigt werden, und desto geringer ist der Aufwand, der zur Überprüfung dieses Pipeline-Abschnitts erforderlich ist.The length of the section during a stressing operation can be checked depends on the Amount of fluid that is introduced into the pipeline can be. The larger the amount of fluid that is with the desired pressure can be pumped into the pipeline, the greater the length of the section being checked can be. The greater the length of the individual Sections, the lower the number of stress events, the to verify a given pipeline section needed, and the lower is the Effort needed to review this pipeline section is required.
Aus der Praxis ist eine Vorrichtung bekannt, bei der mehrere, jeweils eine Baueinheit bildende Pumpen druckseitig gemeinsam an eine Druckleitung angeschlossen sind. Dadurch ergibt sich in der Summe der einzelnen Fördermengen der einzelnen Pumpen eine große Gesamtfördermenge der Vorrichtung.From practice, a device is known in which several, each one unit forming pumps pressure side connected together to a pressure line are. This results in the sum of the individual Flow rates of each pump a large Total delivery of the device.
Bei der bekannten Vorrichtung werden Hochdruckpumpen mit einer möglichst großen ungeraden Anzahl von Zylindern eingesetzt. Dadurch kann die Pulsation der geförderten Flüssigkeit minimiert werden, indem die Pumphübe der einzelnen Zylinder derart aufeinander abgestimmt werden, daß die durch die einzelnen Pumphübe entstehenden Pulsationen einander gegenseitig reduzieren bzw. aufheben.In the known device high pressure pumps are with the largest possible odd number of cylinders used.

In der Praxis hat es sich gezeigt, daß diese Vorrichtung aufgrund der Vielzahl der Module und dem damit verbunden Platzbedarf unhandlich ist. Das Stressen von Pipelines findet jeweils vor Ort an den einzelnen Bauabschnitten der Pipeline statt. Dazu muß die Vorrichtung zu den einzelnen Bauabschnitten der Pipeline transportiert werden. Bei der bekannten Vorrichtung geschieht dies, indem die Vorrichtung in ihre einzelnen Module zerlegt wird und Modulweise an den Einsatzort transportiert wird.In practice, it has been shown that this device due to the variety of modules and the associated Space is unmanageable.
