Abstract

In a pump unit for high-pressure cleaning and disinfecting installations, which consists of a pump and motor, the pump unit is equipped with a pole-changing motor (two-step motor) for controlling different pump capacities. By means of the pole-changing motor, a halving of the pump capacity of the pump can be achieved. Each pump cooperates with a pole-changing motor. A number of pump units is combined to form one constructional unit, the constructional unit being equipped with an electric control device which - depending on the required capacity - causes individual pump units to be switched on or switched off. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Pumpenaggregat für Hochdruck-Reinigungs- und Desinfektionsanlagen, bestehend aus Pumpe und Motor. Bei den bisher bekannten Ausführungsformen wird in der Regel eine Pumpe durch einen Elektromotor angetrieben. Nach der zulässigen Drehzahl der Pumpe richtet sich die Abstufung des der Pumpe vorgeschalteten Getriebes (Zahn- oder Keil­riemenantrieb) oder die Nenndrehzahl des direkt mit der Pumpe gekoppelten Antriebsmotors. Bei zahlreichen Einsatzmöglichkeiten der Pumpe werden oft maximale Leistungen verlangt, die - je nach Leistungsbedarf - aus wirtschaftlichen Gründen nach unten abgestuft sein sollten. Beträgt z.B. die max. Pumpenleistung "100", so ist die min. Pumpenleistung aus wirtschaftli­chen Gründen mit "50" auszulegen. Dieses bedeutet in der Praxis, daß zwei komplette Pumpenaggregate mit je einer Leistung von "50" erforderlich sind. Diese werden parallel geschaltet. Je nach Leistungsan­forderung werden die Pumpenaggregate entweder einzeln oder gemeinsam eingeschaltet. Im letzteren Fall addie­ren sich die Einzelleistungen zu einer Gesamtleistung von "100".The invention relates to a pump unit for high-pressure cleaning and disinfection systems, consisting of a pump and motor. In the previously known embodiments, a pump is usually driven by an electric motor. The grading of the gear upstream of the pump (toothed or V-belt drive) or the nominal speed of the drive motor directly coupled to the pump depends on the permissible speed of the pump. With numerous possible uses of the pump, maximum outputs are often required, which - depending on the output requirement - should be downgraded for economic reasons. For example, the max. Pump output "100", the min. For economic reasons, the pump output should be interpreted as "50". In practice, this means that two complete pump units, each with an output of "50", are required. These are connected in parallel. Depending on the power requirement, the pump sets are switched on either individually or together. In the latter case, the individual services add up to a total service of "100".

Der Erfindung liegt die Aufgabe zugrunde, ein Pumpen­aggregat der gattungsgemäßen Art zu schaffen, bei dem die Pumpenleistung veränderbar ist. Mit einem Pumpenaggregat soll beispielsweise wahlweise eine Leistung von "100" oder "50" erbracht werden können. Zur Lösung dieser Aufgabe wird erfindungsgemäß vorge­schlagen, daß das Pumpenaggregat zur Steuerung unter­schiedlicher Pumpenleistungen mit einem polumschalt­baren Motor (Zweistufen-Motor) ausgerüstet ist. Durch diese Ausbildung wird erreicht, daß für unterschied­liche Pumpenleistungen die Anzahl der benötigten Pum­penaggregate reduziert werden kann. Wurden bisher 10 Pumpenaggregate in einer Groß-Anlage benötigt, so kommt man bei dem erfindungsgemäßen Pumpenaggregat mit der Hälfte aus. Hierdurch werden also die Kosten für die Anschaffung der erforderlichen Pumpenaggregate erheblich verringert. Des weiteren wird eine beträcht­liche Einsparung der Energie erzielt.The invention has for its object to provide a pump unit of the generic type which the pump output is changeable. With a pump unit, for example, an output of "100" or "50" should be possible. To solve this problem, the invention proposes that the pump unit for controlling different pump outputs is equipped with a pole-changing motor (two-stage motor). This configuration ensures that the number of pump units required can be reduced for different pump outputs. If up to now 10 pump units were required in a large-scale system, half of the pump unit according to the invention can be used. As a result, the costs for the purchase of the required pump units are considerably reduced. Furthermore, a considerable saving in energy is achieved.

Bei einer bevorzugten Ausführungsform der Erfindung kann durch den polumschaltbaren Motor eine Halbierung der Förderleistung der Pumpe bewirkbar sein. Solche Pumpenaggregate werden in der Praxis am meisten benö­tigt.In a preferred embodiment of the invention, the pump capacity can be halved by the pole-changing motor. Such pump units are most needed in practice.

Nach einem weiteren Merkmal der Erfindung kann jede Pumpe mit einem polumschaltbaren Motor zusammenwirken. Dieses ist aus wirtschaftlichen Gründen empfehlenswert.According to a further feature of the invention, each pump can interact with a pole-changing motor. This is recommended for economic reasons.

Bei Groß-Anlagen, z.B. in Schlachthöfen, Brauereien oder Großwaschanlagen für Kraftfahrzeuge, können eine Anzahl von Pumpenaggregaten, die vorzugsweise parallel geschaltet sind, zu einer Baueinheit zusammengefaßt sein. In diesem Fall empfiehlt es sich, die Baueinheit mit einer elektrischen Steuereinrichtung auszurüsten, die -je nach Leistungsbedarf - eine Einschaltung oder Abschaltung einzelner Pumpenaggregate bewirkt.In large-scale systems, for example in slaughterhouses, breweries or large-scale washing systems for motor vehicles, a number of pump units, which are preferably connected in parallel, can be combined to form one structural unit. In this case, it is advisable to equip the unit with an electrical control device which, depending on the power requirement, causes individual pump units to be switched on or off.

Auf der Zeichnung ist die Erfindung in zwei Ausfüh­rungsbeispielen schematisch dargestellt:The invention is shown schematically in two exemplary embodiments in the drawing:

Es zeigen:

  • Fig. 1 ein Pumpenaggregat in Vorderansicht, und
  • Fig. 2 fünf Pumpenaggregate, die zu einer Einheit zusammengefaßt worden sind, in Draufsicht.
Show it:
  • Fig. 1 is a pump unit in front view, and
  • Fig. 2 five pump units, which have been combined into one unit, in plan view.

Bei dem ersten Ausführungsbeispiel, welches die Fig. 1 zeigt, besteht das Pumpenaggregat 10 aus einem polumschaltbaren Motor 11 und einer Pumpe 12. Der Motor 11 treibt die Pumpe 12 an. Je nach Bedarf kann über den Motor 11 die max. Leistung oder die um 50 % reduzierte Leistung der Pumpe (11) erbracht werden.In the first exemplary embodiment, which is shown in FIG. 1, the pump assembly 10 consists of a pole-changing motor 11 and a pump 12. The motor 11 drives the pump 12. Depending on requirements, the max. Output or the output of the pump (11) reduced by 50%.

In der Fig. 2 ist das zweite Ausführungsbeispiel gezeigt. Hierbei sind fünf Pumpenaggregate 10 in Parallelschaltung über Rohrleitungen 13, 14 zu einer Baueinheit 15 zusammengefaßt. Der Vorratsbehälter für die Pumpflüssgkeit trägt das Bezugszeichen 16. Die Pumpen 12 saugen über das Rohr 14 die Pumpflüs­sigkeit an und führen diese durch die Verbindungsrohre 17 dem Hauptrohr 1 zu, das mit der Entnahmestelle verbunden ist, an der die einzelnen Spritzpistolen angeschlossen werden. Die Baueinheit 15 ist mit einer nichtdargestellten elektrischen Steuerung ausgerüstet, die die einzelnen Pumpenaggregate 10 ein- bzw. abschal­ten. Wird z.B. nur eine Spritzpistole betätigt, wird über die elektrische Steuervorrichtung lediglich ein Pumpenaggregat 10 eingeschaltet. Für den Fall, daß zehn Spritzpistolen gebraucht werden, erfolgt über die elektrische Steuervorrichtung eine Zuschaltung der übrigen vier Pumpenaggregate 10.2 shows the second exemplary embodiment. Here, five pump units 10 are combined in parallel via pipes 13, 14 to form a unit 15. The reservoir for the pumping liquid bears the reference number 16. The pumps 12 draw in the pumping liquid via the pipe 14 and feed it through the connecting pipes 17 to the main pipe 1, which is connected to the extraction point to which the individual spray guns are connected. The assembly 15 is equipped with an electrical control, not shown, which switches the individual pump units 10 on or off. If, for example, only one spray gun is actuated, only one pump unit 10 is switched on via the electrical control device. In the event that ten spray guns are needed, the remaining four pump units 10 are switched on via the electrical control device.

Wie bereits erwähnt, sind die dargestellten Ausfüh­rungsformen nur beispielsweise Verwirklichungen der Erfindung. Diese ist nicht darauf beschränkt. Es sind noch mancherlei Abänderungen und Ausbildungen möglich. So könnten auch mehr als fünf Pumpenaggregate 10 miteinander verbunden und durch ein gemeinsames Gehäuse zu einer zusammensetzbaren Baueinheit 15 vereinigt sein.As already mentioned, the illustrated embodiments are only examples of realizations of the invention. This is not limited to this. There are still various changes and training options. In this way, more than five pump assemblies 10 could also be connected to one another and combined to form a modular unit 15 by a common housing.
