Abstract
Description
Die
Erfindung bezieht sich auf eine Kreiselpumpe mit einem Spiralgehäuse.
Die Erfindung ist ferner auf die Verwendung der Kreiselpumpe abgestellt.
Kreiselpumpen mit Spiralgehäusen sind bekannt. In der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Kreiselpumpe mit einem Spiralgehäuse zu schaffen, bei der ein Eintreten von Flüssigkeit oder Dampf aus dem den Rotor umgebenden Nassraum in den Trockenraum vollständig vermieden wird.Of the Invention is therefore the object of a centrifugal pump to create a spiral housing, in which an entrance liquid or vapor from surrounding the rotor Wet room in the drying room is completely avoided.
Die der Erfindung zugrunde liegende Aufgabe wird durch eine Kreiselpumpe mit einem Spiralgehäuse gelöst, das aus einem ersten Gehäuseteil und einem zweiten Gehäuseteil besteht, bei dem das zweite Gehäuseteil im mittleren Bereich durchgehend becherförmig zur Aufnahme des im Nassraum N befindlichen Rotors ausgebildet ist und im becherförmigen Bodenteil ein Lager für die drehbare Lagerung des Rotors ausbildet, wobei um das zweite Gehäuseteil außen im Bereich des Rotors im Trockenraum T ein Stator angeordnet ist. Das zweite Gehäuseteil ist im mittleren Bereich durchgehend becherförmig ausgebildet, was bedeutet, dass es um die Längsachse einen nahezu zylindrischen Teil mit abschließendem Boden ausbildet. Durch die becherförmige Ausbildung wird der Nassraum N definiert, der zur Aufnahme des Rotors vorgesehen ist. Das zweite Gehäuseteil bildet im becherförmigen Bodenteil ein Lager für die drehbare Lagerung des Rotors aus, wobei der becherförmige Bodenteil entweder selber als Lager dient oder lediglich zur Aufnahme eines Lagers für den Rotor vorgesehen ist.The The object underlying the invention is achieved by a centrifugal pump solved with a spiral casing, which consists of a first Housing part and a second housing part, in which the second housing part in the middle area continuously cup-shaped for receiving the wet space N located Rotor is formed and in the cup-shaped bottom part forming a bearing for the rotatable mounting of the rotor, being around the second housing part outside in the area of the rotor in the drying space T a stator is arranged. The second Housing part is cup-shaped throughout in the middle area formed, which means that there is a longitudinal axis forms almost cylindrical part with a final bottom. Due to the cup-shaped formation of the wet space N defined, which is intended to receive the rotor. The second housing part forms a cup in the cup-shaped bottom part for the rotatable mounting of the rotor, wherein the cup-shaped Floor part either itself serves as a warehouse or just for recording a bearing is provided for the rotor.
Es hat sich in überraschender Weise gezeigt, dass durch die durchgehende becherförmige Ausgestaltung des zweiten Gehäuseteils ein Eintreten von Flüssigkeit aus dem Nassraum N in den Trockenraum T vollständig vermieden werden kann. Es ist in vorteilhafter Weise nicht erforderlich, den Nassraum N vom Trockenraum T durch Dichtelemente über ein separates Spaltrohr abzutrennen. Dadurch ist eine durchgehende Abtrennung des Trockenraums T vom Nassraum N auch bei längeren Betriebszeiten gewährleistet. Auf die Anordnung eines separaten Spaltrohres wird dabei in vorteilhafter Weise vollständig verzichtet.It has surprisingly been shown by the continuous cup-shaped configuration of the second housing part an entry of liquid from the wet space N in the Drying room T can be completely avoided. It is advantageously not required, the wet room N from the drying room T through sealing elements via a separate can. As a result, a continuous separation of the drying space T from the wet room N guaranteed even with longer operating times. On the arrangement of a separate split tube is doing in an advantageous Completely omitted.
Nach einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass das zweite Gehäuseteil im äußeren Bereich eine im Längsschnitt bogenförmige Begrenzung senkrecht zur Strömungsrichtung des vom Eintritt E herströmenden Mediums aufweist. Der genaue bogenförmige Verlauf wird dabei strömungstechnisch durch eine ingenieurmäßige Auslegung optimiert. Dadurch lässt sich in vorteilhafter Weise eine optimale Einstellung der Strömungsverhältnisse im Spiralgehäuse einstellen, so dass der erforderliche Bauraum für die Kreiselpumpe vorteilhaft verkleinert werden kann.To A preferred embodiment of the invention provides that the second housing part in the outer area a longitudinally arcuate boundary perpendicular to the flow direction of the inflowing from the inlet E Medium has. The exact arcuate course becomes thereby aerodynamically by an engineering interpretation optimized. This can be an optimal way in an advantageous manner Adjustment of the flow conditions in the volute casing adjust so that the required space for the centrifugal pump can be advantageously reduced.
Gegenstand der Erfindung ist ferner die Verwendung der Kreiselpumpe als Kühlwasser-Kreiselpumpe in einem Kraftfahrzeug. Kühlwasser-Kreiselpumpen in Kraftfahrzeugen müssen über längere Zeit einwandfrei funktionieren, wobei Schädigungen von elektronischen Bauteilen im Trockenraum T verhindert werden müssen. Die Verwendung der Kreiselpumpe als Kühlwasser-Kreiselpumpe in einem Kraftfahrzeug ist somit besonders vorteilhaft.object The invention further relates to the use of the centrifugal pump as a cooling water centrifugal pump in a motor vehicle. Cooling water centrifugal pumps in motor vehicles must be impeccable for a long time work, causing damage to electronic components in the drying room T must be prevented. The usage the centrifugal pump as a cooling water centrifugal pump in a motor vehicle is thus particularly advantageous.
