Abstract
Es sind schon Förderaggregate bekannt, mit einer aus einem Aluminiumwerkstoff bestehenden Pumpenkammer und einem in der Pumpenkammer angeordneten Rotor, wobei die Pumpenkammer mit einer anodischen Oxidationsbeschichtung versehen ist, um einen Verschleiß- und Korrosionsschutz insbesondere gegenüber Kraftstoffen zu erreichen. Bei dem erfindungsgemäßen Förderaggregat wird der Verschleiß- und Korrosionsschutz in der Pumpenkammer verbessert. Erfindungsgemäß ist vorgesehen, dass die Beschichtung (30) Nickel enthält.Conveying units are already known, with a pump chamber consisting of an aluminum material and a rotor arranged in the pump chamber, the pump chamber being provided with an anodic oxidation coating in order to achieve wear and corrosion protection, in particular with respect to fuels. With the delivery unit according to the invention, wear and corrosion protection in the pump chamber is improved. According to the invention, the coating (30) contains nickel.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Förderaggregat nach der Gattung des Hauptanspruchs.The Invention is based on a delivery unit according to the preamble of the main claim.
Es ist schon ein Förderaggregat bekannt, mit einer aus einem Aluminiumwerkstoff bestehenden Pumpenkammer und einem in der Pumpenkammer angeordneten Rotor, wobei die Pumpenkammer mit einer anodischen Oxidationsbeschichtung versehen ist, um einen Verschleiß- und Korrosionsschutz insbesondere gegenüber Kraftstoffen zu erreichen. Durch Reibung zwischen dem Rotor und der Pumpenkammer entsteht Verschleiß, der an beiden Bauteilen möglichst gering gehalten werden soll.It is already a pumping unit known, with a pump chamber consisting of an aluminum material and a rotor disposed in the pump chamber, wherein the pump chamber is provided with an anodic oxidation coating to a Wear- and corrosion protection, especially to achieve fuel. By Friction between the rotor and the pump chamber creates wear, the on both components as possible should be kept low.
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Förderaggregat mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass der Verschleiß- und Korrosionsschutz verbessert wird, indem anstatt der anodischen Oxidationsbeschichtung eine Nickelbeschichtung eingesetzt wird. Die Nickelbeschichtung ist porenfrei und damit undurchlässig gegenüber Kraftstoffen.The inventive delivery unit with the characterizing features of the main claim has the Advantage that the wear and corrosion protection is improved by replacing the anodic Oxidation coating a nickel coating is used. The nickel coating is nonporous and therefore impervious to fuels.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Förderaggregates möglich.By in the subclaims listed activities are advantageous developments and improvements of the main claim specified delivery unit possible.
Gemäß einer vorteilhaften Ausführung hat die Beschichtung einen Nickelanteil von 80 bis 100 Gewichtsprozent.According to one advantageous embodiment the coating has a nickel content of 80 to 100 weight percent.
Besonders vorteilhaft ist, wenn die Nickelbeschichtung zusätzlich Phosphor enthält, da auf diese Weise die Härte der Beschichtung optimal einstellbar ist.Especially is advantageous if the nickel coating additionally contains phosphorus, as on this way the hardness the coating is optimally adjustable.
Es hat sich herausgestellt, dass eine Beschichtung mit einem Phosphoranteil von 3 bis 15 Gewichtsprozent besonders gute Eigenschaften hat.It it has been found that a coating with a phosphorus content from 3 to 15% by weight has particularly good properties.
Nach einer vorteilhaften Ausgestaltung hat die Beschichtung beispielsweise eine Schichtdicke von 5 bis 30 Mikrometern.To an advantageous embodiment, the coating, for example a layer thickness of 5 to 30 microns.
Sehr vorteilhaft ist es, wenn in der Beschichtung anstatt Phosphor zumindest ein verschleissbeeinflussender Stoff enthalten ist, da dies eine alternative Möglichkeit zur Einstellung eines optimalen tribologischen Systems darstellt.Very it is advantageous if in the coating instead of phosphorus at least a wear-influencing substance is included, as this is a alternative possibility to set an optimal tribological system.
In einem Ausführungsbeispiel hat sich als verschleissbeeinflussender Stoff Polytetrafluorethylen (PTFE), Siliciumcarbid (SiC), Borcarbid oder Diamant als vorteilhaft erwiesen.In an embodiment has polytetrafluoroethylene as a wear-influencing substance (PTFE), silicon carbide (SiC), boron carbide or diamond as advantageous proved.
Desweiteren vorteilhaft ist, wenn die Pumpenkammer durch einen Deckel und ein Zwischengehäuse gebildet ist, wobei an dem der Pumpenkammer abgewandten Seite des Zwischengehäuses ein Polgehäuse angeordnet ist, das einen Elektromotor enthält, der zum Antrieb des Rotors vorgesehen ist.Furthermore is advantageous if the pump chamber through a lid and a intermediate housing is formed, wherein on the pump chamber side facing away from the intermediate housing a pole housing is arranged, which contains an electric motor, which is to drive the rotor is provided.
Die Verwendung einer Nickelbeschichtung an den Wandungen der Pumpenkammer einer Seitenkanalpumpe ist besonders vorteilhaft, da auf diese Weise die gleichbleibende Funktion der Pumpe über ihre Lebensdauer sichergestellt ist. Seitenkanalpumpen erfordern enge Spaltmaße im Mikrometerbereich zwischen dem Laufrad und der Pumpenkammer, die zu Verschleiß und damit zu einem Wirkungsgrad- und Leistungsverlust führen können.The Use of a nickel coating on the walls of the pump chamber a side channel pump is particularly advantageous because in this way ensuring the consistent function of the pump over its lifetime is. Side channel pumps require narrow micrometre gaps between the impeller and the pump chamber, which cause wear and tear can lead to a loss of efficiency and performance.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung vereinfacht dargestellt und in der nachfolgenden Beschreibung näher erläutert.One embodiment the invention is shown in simplified form in the drawing and in the following description explained.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Die Zeichnung zeigt im Schnitt ein vereinfacht dargestelltes Förderaggregat, bei dem die Erfindung Anwendung finden könnte.The Drawing shows in section a simplified illustrated delivery unit, where the invention could find application.
Das Förderaggregat dient dazu, Flüssigkeit, beispielsweise Kraftstoff, aus einem Vorratsbehälter zu einem Verbraucher zu fördern, beispielsweise einer Brennkraftmaschine.The delivery unit serves to liquid, for example Fuel, from a reservoir too to promote a consumer, for example, an internal combustion engine.

Erfindungsgemäß ist vorgesehen, dass die Beschichtung Nickel enthält und durch galvanisches oder chemisches Vernickeln hergestellt ist. Durch die Vernickelung wird eine größere Härte und Verschleißfestigkeit sowie eine größere Korrosionsbeständigkeit gegenüber dem bisher verwendeten Eloxal erreicht. Außerdem wird mit der Vernickelung eine Porenfreiheit erzielt.According to the invention, it is provided that the coating contains nickel and by galvanic or chemical nickel plating is made. By the nickel plating is a greater hardness and wear resistance and a greater corrosion resistance across from reached the previously used anodizing. Also, with the nickel plating achieved a freedom from pores.
