Description

Die Erfindung betrifft eine Tauchpumpe der im Oberbegriff des Hauptanspruchs angegebenen Art.The invention relates to a submersible pump of the type specified in the preamble of the main claim.

Bekannte Tauchpumpen dieser Art, die zum Wegbefördern von Flüssigkeiten eingesetzt werden, besitzen in ihrem Gehäuse einen Auslaß- Anschluß, der je nach Pumpenbauart an der der Standfläche gegenüberliegenden Oberseite der Tauchpumpe oder an der Gehäuseseite angeordnet ist. An diesem Auslaß-Anschluß läßt sich die Leitung anschließen, die das abgepumpte Wasser wegführen soll. Es hat sich nun in der Praxis gezeigt, daß bei einem seitlich liegenden Auslaß-Anschluß immer dann, wenn die Tauchpumpe in einen verhältnismäßig engen, aber dafür hohen Raum gestellt werden muß, durch den unvermeidbaren Zug an der Leitung und durch die Eigenbewegung der Leitung beim Pumpen sowie den Versteifungseffekt durch den sich in der Leitung aufbauenden Druck dieser auf die Tauchpumpe ein Kippmoment ausübt, das zum Umkippen der Tauchpumpe führt. Wenn die Tauchpumpe dann auf der Seite liegt, kann sie kein Wasser mehr abpumpen, sobald in die Einlaßöffnungen Luft gesaugt wird. Das gleiche tritt dann auf, wenn die Tauchpumpe ihren Auslaß- Anschluß an der Oberseite aufweist und sie in einen breiten Behälter oder eine weite Grube zum Auspumpen gestellt wird. Das Gewicht der Leitung und der von ihr ausgeübte Zug sowie die Eigenbewegungen der Leitungen beim Pumpen wirken dann in Bezug auf die Standfläche mit einem verhältnismäßig großen Hebelarm, so daß es leicht zum Umkippen der Tauchpumpe kommt und diese wiederum bereits Luft ansaugt, ehe das Wasser vollständig abgepumpt ist. Bei extrem engen Rohren oder Behältern, in die eine bekannte Tauchpumpe mit seitlichem Auslauf-Anschluß eingesetzt wird, ergibt sich zudem entweder für die Leitung ein starker und einen Leistungsverlust bedeutenden Knick oder es ist sogar unmöglich, die Tauchpumpe mit der seitlich wegführenden Leitung in diesen engen Behälter einzubringen.Known submersible pumps of this type, which are used for transporting liquids away, have an outlet connection in their housing which, depending on the type of pump, is arranged on the top of the submersible pump opposite the base or on the housing side. At this outlet connection, the line can be connected, which should lead the pumped water away. It has now been shown in practice that with a side outlet connection whenever the submersible pump must be placed in a relatively narrow but high space, due to the inevitable tension on the line and by the movement of the line itself Pumps and the stiffening effect due to the pressure building up in the line exerts a tilting moment on the submersible pump, which leads to the submersible pump tipping over. When the submersible pump is on its side, it can no longer pump water out as soon as air is drawn into the inlet openings. The same occurs when the submersible pump has its outlet port on the top and it is placed in a wide container or wide pit for pumping out. The weight of the line and the train it exerts, as well as the movements of the lines when pumping, then act in relation to the footprint with a relatively large lever arm, so that the submersible pump tends to tip over and this in turn sucks in air before the water is complete is pumped out. In the case of extremely narrow pipes or containers in which a known submersible pump with a lateral outlet connection is used, there is either a strong kink in the line and a loss of power, or it is even impossible to place the submersible pump with the laterally leading line in these narrow lines Bring in containers.

Aus der DE-A 1 938232 ist eine Tauchpumpe zum Fördern dickflüssiger Stoffe bekannt, die in ihrem Gehäuseoberteil zwei Austrittsöffnungen aufweist, von denen die eine nach oben und die andere zur Seite gerichtet ist. Die Öffnungen sind wahlweise von einer im Gehäuseoberteil gelagerten Klappe verschließbar. Die Pumpe weist am unteren Gehäuseteil einen senkrecht nach unten gerichteten Dorn auf, mit dem sie in die zu fördernden dickflüssigen Stoffe zur eigenen Standfestigkeit gesteckt wird. Ein freies Stehen auf glatten Boden um Wasser zu fördern, ist mit dieser Pumpe nicht möglich. Die vom Gehäuseoberteil seitlich abgehende Austrittsöffnung vermindert durch die Kopflastigkeit mit den anzusetzenden Schläuchen zusätzlich die Standfestigkeit.From DE-A 1 938232 a submersible pump for conveying viscous substances is known which has two outlet openings in its upper housing part, one of which is directed upwards and the other is directed to the side. The openings can optionally be closed by a flap mounted in the upper part of the housing. The pump has a vertically downward mandrel on the lower part of the housing, with which it is inserted into the viscous substances to be pumped for its own stability. It is not possible to stand on smooth ground to convey water with this pump. The outlet opening, which goes out laterally from the upper part of the housing, additionally reduces the stability due to the top heaviness with the hoses to be attached.

Ferner ist aus der AU-B422521 eine besonders gekapselte Tauchpumpe bekannt, die das Wasser von der Seite ansaugt und es über Ausgänge im oberen Gehäuseteil nach oben oder zur Seite abgibt. Durch die seitlich gelegte Ansaugfläche der gesamten Pumpenhöhe fördert diese Pumpe nur, wenn das Gehäuse völlig unter dem Wasserspiegel liegt. Durch die ausschließlich im oberen Gehäuseteil vorgesehenen Ausgänge, an denen die Abführrohre oder Schläuche anzuschließen sind, ist die Pumpe kopflastig und bietet keinen festen Stand, der für das Abpumpen von Bodenwasser mit geringer Höhe notwendig wäre, wobei die Ansaugöffnung gegen den Boden gerichtet sein müßte.Furthermore, a specially encapsulated submersible pump is known from AU-B422521, which sucks in the water from the side and releases it via outputs in the upper housing part upwards or to the side. Due to the lateral suction surface of the entire pump height, this pump only pumps when the housing is completely below the water level. Due to the exits provided exclusively in the upper part of the housing, to which the discharge pipes or hoses are to be connected, the pump is top-heavy and does not offer a firm stand, which would be necessary for pumping out low-level ground water, whereby the suction opening should be directed towards the ground.

Der Erfindung liegt die Aufgabe zugrunde, eine Tauchpumpe der eingangs genannten Art zu schaffen, bei deren Verwendung unabhängig von den jeweils äußeren Gegebenheiten eine optimale Standsicherheit auf der Standfläche gewährleistet ist, und die auch in extrem engen Behältern eingesetzt werden kann, deren Innendurchmesser nur geringfügig größer ist als der Außendurchmesser derTauchpumpe.The invention has for its object to provide a submersible pump of the type mentioned, when using it, regardless of the external circumstances, an optimal stability is guaranteed on the stand, and which can also be used in extremely narrow containers, the inner diameter of which is only slightly larger is the outer diameter of the submersible pump.

Die gestellte Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Hauptanspruchs angegebenen Merkmale gelöst.The object is achieved according to the invention by the features specified in the characterizing part of the main claim.

Infolge der beiden sowohl wahlweise als auch gemeinsam nutzbaren Auslaß-Anschlüsse kann die Leitung zum Abführen des abgepumpten Wassers in Anpassung an die jeweils vorliegenden, äußeren Bedingungen entweder seitlich oder oben angeschlossen werden. Die Kippgefahr für die Tauchpumpe wird dadurch auch bei unebenen oder nachgiebigem Untergrund auf ein Minimum reduziert. Ferner läßt sich die erfindungsgemäß ausgebildete Tauchpumpe in extrem enge Behälter stellen, deren lichte innere Weite nur geringfügig größer zu sein braucht, als es der Außendurchmesser der Tauchpumpe ist. Erzielt wird dies durch die oberseitige Wegführung der Anschlußleitung. Denkbar ist ferner, daß an beiden Auslaß-Anschlüssen eine Leitung angeschlossen wird, so daß entweder zwei Verbrauchsstellen beliefert werden können oder ein entsprechend verdoppelter Durchsatz erreicht wird.As a result of the two optional and jointly usable outlet connections, the line for discharging the pumped water can be connected either laterally or at the top in accordance with the prevailing external conditions. This reduces the risk of the submersible pump tipping to a minimum, even on uneven or flexible ground. Furthermore, the submersible pump designed according to the invention can be placed in extremely narrow containers, the clear inner width of which need only be slightly larger than the outside diameter of the submersible pump. This is achieved by routing the connecting cable at the top. It is also conceivable that a line is connected to both outlet connections, so that either two consumption points can be supplied or a correspondingly doubled throughput is achieved.

Damit bei Anschließen nur einer Leitung die tatsächliche Pumpenleistung genutzt werden kann, ist es zweckmäßig, wenn die Maßnahme von Anspruch 2 verwirklicht ist. Der jeweils nicht benötigte Auslaß-Anschluß wird dann verschlossen.So that the actual pump power can be used when connecting only one line, it is expedient if the measure of claim 2 is implemented. The outlet connection that is not required is then closed.

Ein weiterer, wichtiger Gedanke ist dem Anspruch 3 zu entnehmen. Die beiden übereinander angeordneten Auslaß-Anschlüsse befinden sich hierbei an einer Seite des Gehäuses, so daß sich im Inneren des Gehäuses vereinfachte Strömungsführungen ergeben. Da der erste Auslaß- Anschluß relativ tief an der Gehäuseseite liegt, wirken das Gewicht, die dynamischen Kräfte und evtl. Zugbelastungen in der Leitung in Bezug auf die Standfläche mit einem wünschenswert kleinen Hebelarm, wodurch das unerwünschte Umkippen der Tauchpumpe vermieden wird.Another important idea can be found in claim 3. The two stacked outlet connections are located on one side of the housing, so that simplified flow guides result in the interior of the housing. Since the first outlet connection is relatively deep on the housing side, the weight, the dynamic forces and possibly tensile loads in the line act in relation to the base with a desirably small lever arm, thereby preventing the submersible pump from tipping over undesirably.

Zweckmäßig sind ferner die aus Anspruch 4 hervorgehenden, die Ausströmrichtung betreffenden Merkmale.The features of claim 4 which relate to the outflow direction are also expedient.

Ein herstellungstechnisch günstiges Merkmal geht weiterhin aus Anspruch 5 hervor. Über diese Anschlußflansche läßt sich nicht nur ein dichtes Anschließen der abführenden Leitung herbeiführen.A feature that is favorable in terms of production technology is also evident from claim 5. These connection flanges can not only be used for tight connection of the outgoing line.

Zweckmäßig ist ferner die aus Anspruch 6 erkennbare Maßnahme, da damit in einfacher Weise der jeweils nicht benötigte Auslaß-Anschluß geöffnet und der andere verschlossen werden kann. Die Flansche passen wechselweise auf die Flansche der Auslaß-Anschlüsse, so daß kein gesondertes Zubehör erforderlich ist, sondern die Tauchpumpe unmittelbar an der Baustelle auf die jeweilige Verwendungsart umrüstbar wird.The measure recognizable from claim 6 is also expedient, since the outlet connection which is not required in each case can thus be opened in a simple manner and the other can be closed. The flanges alternately fit on the flanges of the outlet connections, so that no special accessories are required, but the submersible pump can be converted to the respective type of use directly at the construction site.

Ein weiterer, wichtiger Gedanke geht aus Anspruch 7 hervor. In diesem Schraubanschluß läßt sich besonders rasch und dicht die auf die Nennweite des Schraubanschlusses abgestimmte Leitung bzw. deren Anschlußmuffe anbringen.Another important idea emerges from claim 7. In this screw connection, the line or its connecting sleeve that is matched to the nominal size of the screw connection can be attached particularly quickly and tightly.

Da es zweckmäßig ist, die Außenabmessungen der Tauchpumpe möglichst klein zu halten, ist auch das Merkmal von Anspruch 8 wesentlich. Zudem läßt sich eine derartige Ausbildung herstellungstechnisch einfach realisieren, da das Rohr und die Anschlüsse gleich von vornherein eingeformt werden können.Since it is expedient to keep the outer dimensions of the submersible pump as small as possible, the feature of claim 8 is also essential. In addition, such a design can be easily implemented in terms of production technology, since the tube and the connections can be molded in from the outset.

Das Kapselgehäuse einer solchen Tauchpumpe ist bei dem oft rauhen Betrieb auf einer Baustelle erheblichen Belastungen von außen unterworfen. Zur Verbesserung der Gestaltfestigkeit und auch zur Erhöhung der Robustheit ist das Kapselgehäuse deshalb außen verrippt. Die Verrippung hat den zusätzlichen Effekt einer Wärmeableitung nach außen. Da das in die Gehäuseseite integrierte Rohr an sich eine exponierte Zone, was Stöße oder Schläge betrifft, darstellt, ist es zweckmäßig, wenn das Rohr gemäß Anspruch 9 in die Verrippung einbezogen und deshalb gegen Beschädigungen geschützt ist.The capsule housing of such a submersible pump is subjected to considerable external loads in the often rough operation on a construction site. The capsule housing is therefore ribbed on the outside to improve the structural strength and also to increase the robustness. The ribbing has the additional effect of heat dissipation to the outside. Since the tube integrated into the housing side represents an exposed zone as far as shocks or impacts are concerned, it is expedient if the tube is included in the ribbing according to claim 9 and is therefore protected against damage.

Herstellungstechnisch ist es besonders einfach und kostengünstig, gemäß Anspruch 10 vorzugehen. Wenn das Kapselgehäuse aus Kunststoff oder einem Druckguß besteht, lassen sich die Auslaß-Anschlüsse besonders einfach integrieren.Technically, it is particularly simple and inexpensive to proceed according to claim 10. If the capsule housing is made of plastic or a die-cast, the outlet connections can be integrated particularly easily.

An embodiment of the invention is explained below with reference to the drawing. Show it

  • 3 shows a schematic representation of a second application.

Eine Tauchpumpe 1 gemäß Fig. 1, die zum Pumpen oder Fördern von Klar- und Schmutzwasser für Haus und Garten, Hof und Baustelle einsetzbar ist, besitzt ein Kapselgehäuse 3 aus Kunststoff oder Druckguß mit horizontal umlaufenden Verstärkungsrippen 4, sowie einen Unterteil 2 mit Ansaugteil und auf der Oberseite 5 einen Verschlußdeckel 6. Der Verschlußdeckel 6 und der Unterteil 2 sind mit dem Kapselgehäuse 3 beispielsweise verschraubt. Die Oberseite 5 wird von einem Griffbügel 7 überspannt, dessen beide Bügelenden mit Befestigungsschrauben 8 am Kapselgehäuse 3 lösbar befestigt sind. Das Kapselgehäuse 3 besitzt eine im wesentlichen flache Gehäuseseite 3a und drei gekrümmte Gehäuseseiten 3b, wobei die in Fig. 1 hintenliegenden nicht sichtbar sind.A submersible pump 1 according to FIG. 1, which can be used for pumping or pumping clear and dirty water for the home and garden, yard and construction site, has a capsule housing 3 made of plastic or die-cast with horizontally extending reinforcing ribs 4, and a lower part 2 with suction part and on the top 5 a closure cover 6. The closure cover 6 and the lower part 2 are screwed to the capsule housing 3, for example. The top 5 is spanned by a handle 7, the two ends of the bracket are releasably attached to the capsule housing 3 with fastening screws 8. The capsule housing 3 has an essentially flat housing side 3a and three curved housing sides 3b, the ones lying behind in FIG. 1 not being visible.

In die Gehäuseseite 3a ist ein Rohr 9 baulich eingegliedert, das hinter der Außenseite der Gehäuseseite 3a entlang nach oben verläuft und zu einem zweiten Auslaß-Anschluß 10 führt, der in Form eines eine Auslauföffnung umfassenden Flansches 10a ausgebildet ist. Die Oberseite des Flansches 10a liegt in etwa in der Höhe der Oberseite des Gehäuses 3. Auf dem Flansch 10a ist ein weiterer Flansch 11 mit Befestigungsschrauben 12 festgelegt, der in Verlängerung der Auslaß-Öffnung bzw. des Rohres 9 einen Anschlußstutzen 13 mit einem Innengewinde 14 zum Anschließen einer Leitung trägt.A tube 9 is structurally integrated into the housing side 3a, which runs behind the outside of the housing side 3a upwards and leads to a second outlet connection 10 which is designed in the form of a flange 10a which comprises an outlet opening. The upper side of the flange 10a lies approximately at the height of the upper side of the housing 3. A further flange 11 with fastening screws 12 is fixed on the flange 10a, which in extension of the outlet opening or the tube 9 has a connecting piece 13 with an internal thread 14 to connect a line.

In etwa in Verlängerung des Rohres 9 liegt in der unteren Hälfte der Gehäuseseite 3a ein erster Auslaß-Anschluß 15, der durch einen in die Gehäuseseite 3a integrierten Flansch 15a definiert wird. Bei diesem Ausführungsbeispiel ist auf dem Flansch 15a ein weiterer, ebener Flansch 16 mit Befestigungsschrauben 12 festgelegt, der als Verschlußdeckel 17 für die Öffnung des Auslaß-Anschlusses 15 wirkt.Approximately in extension of the tube 9 is in the lower half of the housing side 3a, a first outlet port 15, which is defined by a flange 15a integrated into the housing side 3a. In this embodiment, a further, flat flange 16 is fixed with fastening screws 12 on the flange 15a, which acts as a closure cover 17 for the opening of the outlet connection 15.

Der Unterteil 2, der die Standfläche 2a für die Tauchpumpe 1 auf dem Untergrund definiert, weist bei dieser Ausführungsform Standfüße 18, 20 sowie Einlaßöffnungen 19 zum Ansaugen des Wassers auf.In this embodiment, the lower part 2, which defines the standing surface 2a for the submersible pump 1 on the ground, has feet 18, 20 and inlet openings 19 for sucking in the water.

An der Gehäuseseite 3b ist mit einer Schelle 23 die Schaltleitung 22 eines Schwimmerschalters 21 befestigt, mit der der nicht dargestellte innere Pumpenteil der Tauchpumpe 1 in Gang gesetzt wird, sobald das Wasserniveau um die Tauchpumpe herum eine bestimmte Höhe überschreitet. Der Schwimmerschalter 21 und die Betätigung des inneren Pumpenteils durch ihn ist bekannt und braucht deshalb nicht näher erläutert zu werden.On the housing side 3b, the switching line 22 of a float switch 21 is fastened with a clamp 23, with which the inner pump part, not shown, of the submersible pump 1 is started as soon as the water level around the submersible pump exceeds a certain height. The float switch 21 and the actuation of the inner pump part by it are known and therefore need not be explained in more detail.

Zweckmäßigerweise können die Flansche 11 und 16 gegeneinander vertauscht werden, so daß dann der erste Auslaß-Anschluß 15 zum Anschließen einer Leitung benutzbar ist, während der zweite Auslaß-Anschluß 10 dann verschlossen wird. Denkbar ist ferner, daß beide Auslaß-Anschlüsse geöffnet werden, damit zwei Leitungen für zwei Verbraucher oder für einen verdoppelten Durchsatz angeschlossen werden können.The flanges 11 and 16 can expediently be interchanged so that the first outlet connection 15 can then be used to connect a line, while the second outlet connection 10 is then closed. It is also conceivable that both outlet connections are opened so that two lines can be connected for two consumers or for a doubled throughput.

Aus Fig. 2 ist die stehende Anordnung der Tauchpumpe 1 in einen Brunnenschacht 24 mit waagerechtem Boden 25 erkennbar. Der Griffbügel 7 ist hier über eine Sicherung 27 an einem Querholm 28 des Brunnenschachtes angehängt. Zur Vermeidung der Kipp- oder Schlingergefahr der Tauchpumpe 1 ist hier der erste Auslaß- Anschluß 15 wie in Fig. 1 verschlossen, während am zweiten Auslaß-Anschluß 10 mit dem Flansch 11 eine Leitung 26 für einen Verbraucher 30 angeschlossen ist. Es liegt auf der Hand, daß die Tauchpumpe 1 bei dieser Anordnung der Leitung 26 auch in einen engen Schacht eingebracht werden kann, der nur geringfügig weiter ist, als die Außenabmessungen der Tauchpumpe 1 bei dieser Anordnung der Leitung 26.The standing arrangement of the submersible pump 1 in a well shaft 24 with a horizontal bottom 25 can be seen from FIG. The handle 7 is attached here via a fuse 27 to a cross member 28 of the well shaft. In order to avoid the risk of the submersible pump 1 tipping or rolling, the first outlet connection 15 is closed here as in FIG. 1, while the second outlet connection 10 is closed with the flange 11 a line 26 for a consumer 30 is connected. It is obvious that the submersible pump 1 with this arrangement of the line 26 can also be introduced into a narrow shaft which is only slightly larger than the external dimensions of the submersible pump 1 with this arrangement of the line 26.

In Fig. 3 ist die Tauchpumpe 1 in eine weite Bodenvertiefung 29 eingesetzt und steht mit ihrem Unterteil 2 am Grund. Bei dieser Anbringung ist der zweite Auslauf-Anschluß 10 mit dem Flansch 16 verschlossen, während der erste Auslaß-Anschluß 15 mit dem Flansch 11 das Anschließen der Leitung 26 gestattet. Auch hier wird eine Kippgefahr für die Tauchpumpe vermieden, da die Leitung 26 sehr nahe am Unterteil 2horizontal wegführt und sich deshalb am Grund der Vertiefung 29 abstützen kann bzw. kein nennenswertes Kippmoment auf die Tauchpumpe 1 ausauszuüben vermag.In Fig. 3, the submersible pump 1 is inserted in a wide bottom recess 29 and is at the bottom with its lower part 2. With this attachment, the second outlet connection 10 is closed with the flange 16, while the first outlet connection 15 with the flange 11 allows the line 26 to be connected. Here, too, a risk of tipping for the submersible pump is avoided, since the line 26 leads away very close to the lower part 2 and can therefore be supported on the bottom of the recess 29 or cannot exert any significant tipping moment on the submersible pump 1.

Obwohl die Fig. und 3 dies nicht hervorheben, kann die Tauchpumpe 1 natürlich mit dem Schwimmerschalter 21 von Fig. 1 ausgestattet sein, um selbsttätig jeweils ein- bzw. auszuschalten, wenn das Wasserniveau eine bestimmte Höhe erreicht.Although FIGS. 3 and 3 do not emphasize this, the submersible pump 1 can of course be equipped with the float switch 21 from FIG. 1 in order to switch on and off automatically when the water level reaches a certain height.

Der Flansch 11 hat zweckmäßigerweise einen genormten lnnengewindeanschluß, z. B. 1,25 Zoll für vielseitige Anschlußmöglichkeiten. Wenn das Kapselgehäuse 3 aus Kunststoff oder aus Druckgut hergestellt wird, ergibt sich ein zweckmäßig geringes Gesamtgewicht der Tauchpumpe.The flange 11 advantageously has a standardized internal thread connection, for. B. 1.25 inches for versatile connectivity. If the capsule housing 3 is made of plastic or printed material, the total weight of the submersible pump is expediently low.

Wenn die Tauchpumpe 1 als stationäre Pumpe, z. B. in einer Kellerentwässerungsanlage, eingesetzt wird, die nur eine beschränkte Höhe aufweist, ist es zweckmäßig, das Griffstück 7 wegzulassen.If the submersible pump 1 as a stationary pump, for. B. is used in a basement drainage system, which has only a limited height, it is advisable to omit the handle 7.
