Description

Die Erfindung betrifft ein Spülflüssigkeitspumpensystem, mit einem Pumpenaggregat und mit einer Drehantriebseinrichtung zum Antrieb des Pumpenaggregats. Mit dem Begriff Spülflüssigkeitspumpensystem wird im Rahmen dieser Druckschrift ein Pumpensystem bezeichnet, welches Spülflüssigkeit fördert, die bei dem Vortrieb oder dem Niederbringen von Bohrungen das Bohrloch durchspült.The invention relates to a rinsing liquid pump system, with a pump unit and with a rotary drive device for driving the pump unit. In the context of this publication, the term flushing liquid pump system refers to a pump system which conveys flushing liquid which flushes through the borehole during the advance or drilling of boreholes.

Insbesondere beim Vortrieb oder beim Niederbringen bei Großlochbohrungen wird während des Bohrvorganges Spülflüssigkeit der Bohrung zugeführt. Die Spülflüssigkeit dient einerseits der Schmierung der an der Ortsbrust bzw. an der Bohrungssohle arbeitenden Bohrwerkzeuge sowie der Abstützung der Ortsbrust bzw. der Bohrungswandung. Andererseits kann mit Hilfe der Spülflüssigkeit auch gelöstes Bohrgut aus der Bohrung herausgebracht werden, in dem beispielsweise zentral durch einen hohlen Bohrstrang frische Spülflüssigkeit in dem Bereich der Bohrlochsohle bzw. der Ortsbrust zugeführt wird und somit eine Spülflüssigkeitsströmung erzeugt wird, die gelöstes Bohrgut mitreißt und aus der Bohrung herausbringt.Especially when driving or sinking in large-hole drillings, flushing fluid is supplied to the borehole during the drilling process. The flushing liquid is used on the one hand to lubricate the drilling tools working on the working face or on the bottom of the borehole and to support the working face or the borehole wall. On the other hand, with the aid of the rinsing liquid, loosened drill cuttings can also be brought out of the borehole, for example by supplying fresh rinsing liquid centrally through a hollow drill string in the area of the bottom of the borehole or the working face, thus generating a rinsing liquid flow that entrains loosened drill cuttings and out of the drilling out.

Zur Erzeugung der für das Ausbringen erforderlichen Spülflüssigkeitsströmung sind besonders leistungsstarke Pumpensysteme erforderlich. Die Förderleistung derartiger Pumpensysteme liegt regelmäßig im Bereich von maximal 3000 l/min und einem Druck von maximal 500 bar.Particularly powerful pump systems are required to generate the flushing liquid flow required for application. The pumping capacity of such pump systems is regularly in the range of a maximum of 3000 l/min and a maximum pressure of 500 bar.

Zum Stand der Technik gehören Pumpensysteme, die sich durch eine besonders kompakte Bauweise auszeichnen, da die das Pumpenaggregat antreibende Drehantriebseinrichtung des Pumpensystems oberhalb des Pumpenaggregats angeordnet und an dessen Gehäuseoberseite angeflanscht ist. Die Drehantriebseinrichtungen haben regelmäßig Leistungen von bis zu 1.700 kW.The state of the art includes pump systems which are distinguished by a particularly compact design, since the rotary drive device of the pump system which drives the pump assembly is arranged above the pump assembly and is flanged to the upper side of the housing. The rotary drive devices regularly have outputs of up to 1,700 kW.

Um diese Leistung bzw. das von der Drehantriebseinrichtung gelieferte Drehmoment auf die Eingangswelle des Pumpenaggregats übertragen zu können, ist es bekannt, sowohl die Welle des Drehantriebs als auch die Antriebswelle der Pumpe beidseitig aus dem jeweiligen Gehäuse herauszuführen, so dass jede Welle zwei Wellen-Enden aufweist. Auf jedem Wellenende ist rotationsfest ein Kettenrad gelagert. Die Drehmomentübertragung erfolgt dementsprechend durch zwei parallel zueinander verlaufende Ketten.In order to be able to transmit this power or the torque supplied by the rotary drive device to the input shaft of the pump unit, it is known to lead both the shaft of the rotary drive and the drive shaft of the pump out of the respective housing on both sides, so that each shaft has two shaft ends having. A sprocket wheel is mounted on each shaft end so that it cannot rotate. Torque is therefore transmitted by two chains running parallel to one another.

Nachteilig ist bei derartigen Pumpensystemen, dass der aufgrund der beidseitig laufenden Ketten erforderliche konstruktive Aufwand durch die doppelt benötigten Bauteile und insbesondere durch die 4-fach erforderlichen Wellendurchführungen mit entsprechenden Dichtungsanordnungen hoch ist. Ferner erzeugen die Kettenantriebe im Betrieb einen erheblichen Geräuschpegel.The disadvantage of such pump systems is that the structural complexity required because of the chains running on both sides is high due to the double components required and in particular due to the quadruple shaft bushings with corresponding sealing arrangements. Furthermore, the chain drives generate a considerable level of noise during operation.

Die GB-A-1034058 betrifft Verbesserungen an einem Sonnen- und Planetengetriebe. Zwar ist in diesem Dokument offenbart, diese Verbesserungen, die eine Drehantriebseinrichtung sowie ein ein Antriebsrad und ein Abtriebsrad umfassendes Zahnradgetriebe umfassen, im Zusammenhang mit einer Pumpenanordnung einzusetzen, diese ist jedoch für einen Einsatz in der Süßwarenindustrie vorgesehen. Hinweise darauf, ein Spülflüssigkeitspumpensystem in der erfindungsgemäßen Weise auszugestalten, enthält dieses Dokument daher nicht.the GB-A-1034058 concerns improvements to a sun and planetary gear. Although this document discloses using these improvements, which comprise a rotary drive device and a gear train comprising a drive wheel and a driven wheel, in connection with a pump arrangement, this is intended for use in the confectionery industry. This document therefore does not contain any indications as to how to design a rinsing liquid pump system in the manner according to the invention.

Die US 2004/0060717 A1 betrifft eine Bohrvorrichtung mit einer kompakten Kompressor-Pumpenanordnung. Bei den Pumpen handelt es sich um Hydraulikpumpen, die der Bereitstellung des zur Betätigung der Bohrvorrichtung, beispielsweise Drehen und Stellen des Mastes, mittels Hydraulikzylinder oder Hydraulikmotoren erforderlichen Drucks dient. Der Kompressor dient zur Herstellung von Druckluft, die zum Ausbringen von Bohrgut aus der Bohrung eingesetzt wird. Der Kompressor und die Pumpen sind zu einer Einheit zusammengeflanscht und über Zahnräder mit einer Antriebsachse verbunden, die von einem Rotationsmotor angetrieben wird. Wiederum handelt es sich bei dem Gegenstand dieses Dokuments nicht um eine Spülflüssigkeitspumpe.the U.S. 2004/0060717 A1 relates to a drilling device with a compact compressor-pump arrangement. The pumps are hydraulic pumps which are used to provide the pressure required to actuate the drilling device, for example rotating and positioning the mast, by means of hydraulic cylinders or hydraulic motors. The compressor is used to produce compressed air, which is used to extract drill cuttings from the well. The compressor and pumps are flanged together into one unit and connected via gears to a drive axle driven by a rotary motor. Again, the subject of this document is not an irrigation fluid pump.

Die US 2004/0028540 A1 bezieht sich auf eine manuell angetriebene Pumpen- oder Kompressoranordnung. Zwar ist bei der in Figur 3 dargestellten Ausführungsform eine Wirkverbindung zwischen dem manuellen Antrieb und der Pumpen- bzw. Kompressoreinrichtung mittels ineinandergreifender Zahnräder bewerkstelligt, einen Zusammenhang mit einem Spülflüssigkeitspumpensystem hat dieses Dokument jedoch nicht.the U.S. 2004/0028540 A1 refers to a manually driven pump or compressor assembly. Although in the embodiment shown in FIG. 3 an operative connection is established between the manual drive and the pump or compressor device by means of meshing gear wheels, this document has no connection with a rinsing liquid pump system.

Die US 2004/0219040 A1 zeigt eine Vorrichtung mit einem Summiergetriebe, welches gerade der Bündelung der Leistung mehrerer Motoren dient. Anregungen für ein Spülflüssigkeitspumpensystem mit genau einer Drehantriebseinrichtung enthält diese Druckschrift nicht. Die US2004/0219042 zeigt eine Pumpenanordnung mit einem Motor.the U.S. 2004/0219040 A1 shows a device with a summation gear, which is used to bundle the power of several motors. This document does not contain suggestions for a rinsing liquid pump system with precisely one rotary drive device. the US2004/0219042 shows a pump arrangement with a motor.

Die CN 2 385 075 Y offenbart ein Spülpumpenaggregat. Es umfasst ein Pumpengehäuse, in dem eine Antriebswelle gelagert ist, die ein erstes Zahnrad aufweist, welches sich im Eingriff mit einem zweiten Zahnrad einer ebenfalls in dem Gehäuse gelagerten Kurbelwelle befindet. Die Antriebswelle trägt eine Riemenscheibe, über welche das Spülpumpenaggregat mit einer externen, nicht näher beschriebenen Drehantriebseinrichtung gekoppelt ist.the CN 2 385 075 Y discloses a mud pump assembly. It comprises a pump housing in which a drive shaft is mounted, which has a first gear wheel which is in mesh with a second gear wheel of a crankshaft which is also mounted in the housing. The drive shaft carries a belt pulley, via which the scavenging pump unit is coupled to an external rotary drive device that is not described in detail.

Die US 2,883,874 offenbart eine Spülpumpe mit einem Pumpenaggregat, welche eine in einem Kurbelgehäuse vorgesehene Kurbelwelle umfasst. Die Kurbelwelle ist mit einem Schneckengetriebe verbunden, das in einem Getriebegehäuse vorgesehen ist. Das Getriebegehäuse ist seitlich neben dem Kurbelgehäuse angeordnet und überragt das Kurbelgehäuse in vertikaler Richtung auch nach unten. Hier ragt eine Schneckenwelle aus dem Getriebegehäuse zum Anschluss eines Antriebsmotors heraus.the U.S. 2,883,874 discloses a scavenging pump with a pump unit, which includes a crankshaft provided in a crankcase. The crankshaft is connected to a worm gear provided in a gear case. The transmission housing is arranged laterally next to the crankcase and projects beyond the crankcase in the vertical direction, also downwards. Here, a worm shaft protrudes from the gearbox housing to connect a drive motor.

Die US 4,435,990 offenbart eine portable Getriebeeinheit zur Zwischenschaltung zwischen einer Antriebsquelle und einer angetriebenen Quelle, insbesondere zur Verbindung eines Industriemotors mit einer Spülpumpe. Antriebsmotor, Getriebeeinheit und Spülpumpe sind nebeneinander angeordnet.the U.S. 4,435,990 discloses a portable transmission unit for interposing between a driving source and a driven source, in particular for connecting an industrial engine to a scavenging pump. The drive motor, gear unit and scavenging pump are arranged side by side.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Pumpensystem zu schaffen, welches die vorgenannten Nachteile nicht aufweist.The invention is therefore based on the object of creating a pump system which does not have the aforementioned disadvantages.

Diese Aufgabe ist durch das in Anspruch 1 wiedergegebene Pumpensystem gelöst.This object is achieved by the pump system set out in claim 1.

Dadurch, dass bei dem erfindungsgemäßen Pumpensystem die Drehantriebseinrichtung über ein ein Antriebs- und ein Abtriebsrad umfassendes Zahnradgetriebe mit dem Pumpenaggregat wirkverbunden ist, wird die einem Kettenantrieb eigene Geräuschentwicklung vermieden. Ferner hat sich überraschenderweise gezeigt, dass es zur Übertragung der zum Betrieb des Pumpenaggregats erforderlichen Leistung und Drehmomente ausreicht, ein Zahnradgetriebe nur auf einer Seite des Pumpensystems vorzusehen.Due to the fact that in the pump system according to the invention the rotary drive device is operatively connected to the pump unit via a gear train comprising a drive wheel and a driven wheel, the noise development inherent in a chain drive is avoided. Furthermore, it has surprisingly been found that, in order to transmit the power and torque required to operate the pump unit, it is sufficient to provide a gear train on only one side of the pump system.

Es ist erfindungsgemäß ein Pumpensystem vorgesehen, bei welchem die Drehantriebseinrichtung nur ein einziges Wellenende aufweist, mit dem das Antriebsrad über eine Kupplung drehverbindbar ist.According to the invention, a pump system is provided in which the rotary drive device has only a single shaft end with which the drive wheel can be connected in rotation via a coupling.

Der von dem Zahnradgetriebe hervorgerufene Geräuschpegel kann weiter gesenkt werden, wenn - wie besonders bevorzugt - die Zahnräder des Zahnradgetriebes schräg verzahnt sind.The noise level caused by the gear train can be further reduced if--as is particularly preferred--the gear wheels of the gear train are helically toothed.

In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Pumpensystems dargestellt.In the drawing, an embodiment of a pump system according to the invention is shown.

Das Pumpensystem 100 umfasst ein Pumpenaggregat 1 herkömmlicher Bauart. Dieses Pumpenaggregat 1 umfasst ein Gehäuse 2, aus dessen dem Betrachter zugewandten Seite ein Ende einer Pumpenantriebswelle 3 herausragt. Mit diesem Wellenende ist das Abtriebsrad 4 eines Zahnradgetriebes 5 drehfest verbunden.The pump system 100 includes a pump assembly 1 of conventional design. This pump assembly 1 includes a housing 2, from the side facing the viewer one end of a pump drive shaft 3 protrudes. With this shaft end, the output gear 4 of a gear train 5 is rotatably connected.

Das Zahnradgetriebe 5 dient der Herstellung der Wirkverbindung des Pumpenaggregats mit einer Drehantriebseinrichtung 6, die einen in der Zeichnung nur angedeuteten, beispielsweise hydraulisch oder elektrisch angetriebenen, Rotationsmotor R umfasst.The toothed wheel gear 5 is used to produce the operative connection of the pump unit with a rotary drive device 6, which comprises a rotary motor R, which is only indicated in the drawing and is driven, for example, hydraulically or electrically.

Die Drehantriebseinrichtung 6 umfasst ein Gehäuse 7, welches am Gehäuse 2 des Pumpenaggregats 1 angeflanscht ist.The rotary drive device 6 includes a housing 7 which is flanged to the housing 2 of the pump unit 1 .

Wiederum auf der dem Betrachter zugewandten Seite ragt ein Wellenende einer angetriebenen Welle 8 aus dem Gehäuse 7 der Drehantriebseinrichtung 6 heraus. Es ist über eine Schaltkupplung 12 mit einem Antriebsrad 9 verbunden, die wahlweise das Antriebsrad 9 drehfest mit dem Wellenende verbindet oder löst. Das Antriebsrad 9 ist mit dem Abtriebsrad 4 über ein Zwischenrad 10 gekoppelt, welches drehbar in einem Gehäuse 11 des Zahnradgetriebes gelagert ist. Anstatt der Schaltkupplung kann nicht erfindungsgemäß auch eine elastische, nicht schaltbare Kupplung vorgesehen sein, die das Wellenende permanent mit dem Antriebsrad verbindet.Again, on the side facing the viewer, a shaft end of a driven shaft 8 protrudes from the housing 7 of the rotary drive device 6 . It is connected to a drive wheel 9 via a clutch 12, which selectively connects or releases the drive wheel 9 in a rotationally fixed manner to the end of the shaft. The drive wheel 9 is coupled to the driven wheel 4 via an intermediate wheel 10 which is rotatably mounted in a housing 11 of the gear train. According to the invention, instead of the clutch, an elastic, non-shiftable clutch can also be provided, which permanently connects the shaft end to the drive wheel.

Die Verzahnung des Zwischenrads 10 befindet sich im Eingriff mit den Verzahnungen des Antriebsrades 9 und des Abtriebsrades 4. Zwecks Lärmreduzierung sind die Räder des Zahnradgetriebes schräg verzahnt. The toothing of the intermediate wheel 10 is in mesh with the toothing of the drive wheel 9 and the driven wheel 4. The wheels of the gear train are helically toothed to reduce noise.
