Description
Die Erfindung betrifft eine Hubkolbenpumpe zum Fördern oder zum Dosieren von Flüssigkeit entsprechend dem Oberbegriff des ersten Patentanspruchs und ein Verfahren zum Zusammenbau der Hubkolbenpumpe.The invention relates to a reciprocating pump for conveying or dosing of liquid according to the preamble of the first claim and a method for assembling the reciprocating pump.
Hubkolbenpumpen mit elektromagnetischem Antrieb sind bekannt, zum Beispiel aus der Druckschrift
Für die verschiedenen Anwendungen in den Bereichen Fahrzeugheizsysteme, Kraftstoffnacheinspritzung und Reaktionsmitteleinspritzung werden unterschiedliche Leitungsanschlüsse benötigt. Bei ausreichend großer Stückzahl in einem Anwendungsfall ist es wirtschaftlich vertretbar, für die Herstellung und Prüfung für den Anwendungsfall spezifische Vorrichtungen und einen spezifischen Prüfstand zur Endkontrolle einzurichten.For the various applications in the areas of vehicle heating systems, post-injection fuel injection and reactant injection, different line connections are required. With sufficiently large numbers in one application, it is economically feasible to set up for the manufacture and testing for the application specific devices and a specific test bench for final inspection.
Wenn aber die Stückzahlen in mehreren Anwendungsfällen mit unterschiedlichen Leitungsanschlüssen keine spezifischen Vorrichtungen und Prüfstände rechtfertigen, ist es erforderlich, mehrere Anwendungsfälle für einen Satz Vorrichtungen und für einen Prüfstand zusammenzufassen. Das macht es dann erforderlich, einlassseitige und auslassseitige Anschlussbauteile vorzusehen, die nach der Funktionskontrolle der Hubkolbenpumpe in entsprechende Aufnahmebohrungen in betreffende Gehäusebauteile eingedrückt und an den Hubkolbenpumpen befestigt werden.But if the numbers in several applications with different line connections do not justify specific devices and test benches, it is necessary to summarize several use cases for a set of devices and for a test bench. This then makes it necessary to provide inlet-side and outlet-side connection components, which are pressed into corresponding receiving bores into relevant housing components and fastened to the reciprocating pumps after the functional check of the reciprocating piston pump.
Da diese Prozessschritte nach der Funktionskontrolle erfolgen, dürfen dabei keinesfalls Partikel von den Bauteilen abplatzen, diese Partikel würden die Hubkolbenpumpen kontaminieren und gegebenenfalls eintretende Folgen dieser Kontamination würden vor der Auslieferung nicht mehr entdeckt.Since these process steps take place after the functional check, particles must never chip off from the components, these particles would contaminate the reciprocating pumps and any consequences of this contamination would not be detected before delivery.
Die Aufgabe dieser Erfindung ist es daher, das Eindrücken und Befestigen der Anschlussbauteile nach der Funktionskontrolle der Hubkolbenpumpe ohne Freisetzung von Partikeln zu ermöglichen. Außerdem soll eine kostengünstige Montage der Hubkolbenpumpe ermöglicht werden.The object of this invention is therefore to enable the insertion and fastening of the connection components after the functional control of the reciprocating pump without release of particles. In addition, a cost-effective installation of the reciprocating pump to be made possible.
Die kennzeichnenden Merkmale des ersten Anspruchs ermöglichen die Lösung der Aufgabe. Die weiteren Ansprüche beschreiben vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.The characterizing features of the first claim enable the solution of the problem. The other claims describe advantageous embodiments and modifications of the invention.
Die erfindungsgemäße Hubkolbenpumpe ist so gestaltet, dass anwendungsspezifisch unterschiedliche Anschlussbauteile zur Anwendung kommen können. Damit lassen sich kundenseitig die in den unterschiedlichen Anwendungen erforderlichen Leitungen mit ihren unterschiedlichen Kupplungen anschließen.The piston pump according to the invention is designed so that application-specific different connection components can be used. This allows the customer to connect the cables required in the various applications with their different couplings.
Diese Anschlussbauteile werden nach der Funktionskontrolle der Hubkolbenpumpen in Aufnahmebohrungen von Gehäusebauteilen eingedrückt und befestigt. Damit ist es möglich, die Basis-Hubkolbenpumpen ohne die Anschlussbauteile gemeinsam in mehreren Montageprozessen unter Verwendung derselben Vorrichtungen zusammenzubauen und auch auf demselben Prüfstand einer Funktionskontrolle zu unterziehen.These connection components are pressed into the mounting holes of housing components and fastened after the functional check of the reciprocating pumps. This makes it possible to assemble the basic reciprocating pumps without the connection components together in several assembly processes using the same devices and to subject to a function check on the same test stand.
Das Eindrücken und Befestigen der Anschlussbauteile geschieht nach der Funktionskontrolle, daher ist es erforderlich, diese nachgeschalteten Prozesse sehr sicher bezüglich der Entstehung von Verschmutzungspartikeln auszuführen.The pressing in and fastening of the connection components is done after the function check, therefore it is necessary to perform these downstream processes very safe with regard to the formation of soiling particles.
Die Hauptursache für die Freisetzung von verschmutzenden Partikeln bei Eindruck- und Befestigungsprozessen ist das Abplatzen von Partikeln aus einer korrosionsschützenden Beschichtung, wie zum Beispiel einer Verzinkung.The main cause of the release of polluting particles during indentation and attachment processes is the spalling of particles from a corrosion protective coating, such as galvanizing.
Daher muss in diesem Fall die Gefahr eines solchen Abplatzens unbedingt vermieden werden. Auch Schweißprozesse oder Verschraubungsprozesse können Partikel freisetzen. Wenn geschweißt oder verschraubt werden soll, müssen geeignete Vorkehrungen getroffen werden, dass mindestens keine Partikel in das Innere der Hubkolbenpumpe eindringen können. Eine mögliche Lösung der Teilaufgabe ist es, Beschichtungen zu vermeiden und die betroffenen Gehäusebauteile aus rostfreien Werkstoffen zu erstellen. Dieser Weg wird hier nicht gewählt.Therefore, in this case, the risk of such chipping must be avoided at all costs. Welding processes or screwing processes can also release particles. If welding or bolting is required, suitable precautions must be taken to prevent at least particles from entering the interior of the reciprocating pump. A possible solution to the subtask is to avoid coatings and create the affected housing components from stainless materials. This path is not chosen here.
Eine bevorzugte Lösung der Teilaufgabe besteht darin, die Anschlussbauteile aus Kunststoff herzustellen, sie auf Gehäusebauteile aufzustecken und dabei die Leitungsführung abzudichten und schließlich radial außenliegende Zonen der Anschlussbauteile mit einer Kunststoffumspritzung der Spulenbaugruppe zu verschweißen, vorzugsweise durch Schallschweißung. Alternativ werden die Anschlussbauteile mit der Kunststoffumspritzung verschraubt. In jedem Fall stellen die geeignet positionierten Dichtungen sicher, dass während des Prozesses keine Partikel in das Innere der Pumpe eindringen können.A preferred solution of the subtask is to make the connection components made of plastic, aufzustecken them on housing components while sealing the wiring and finally to weld radially outer zones of the connection components with a plastic extrusion of the coil assembly, preferably by sonic welding. Alternatively, the connection components are screwed to the plastic extrusion. In any case, the properly positioned seals ensure that no particles can penetrate into the interior of the pump during the process.
Bei der Funktionskontrolle wird die Hubkolbenpumpe auf ihre Förderleistung, die innere Dichtheit in Förderrichtung bei Stillstand und die innere Dichtheit gegen die Förderrichtung bei Stillstand in einem Prüfstand geprüft.During the functional check, the reciprocating pump is tested for its delivery rate, the inner tightness in the conveying direction at standstill and the inner tightness against the conveying direction at standstill in a test rig.
Nach dem Einpressen oder Einschrauben der Anschlussbauteile muss die Hubkolbenpumpe noch auf externe Leckage geprüft werden, dazu sind jeweils für die eingesetzten Anschlussbauteile spezifische Vorrichtungen erforderlich, um die Hubkolbenpumpe anzuschließen.After pressing in or screwing in the connection components, the reciprocating pump must still be checked for external leakage, in addition to the connection components used specific devices required to connect the reciprocating pump.
Zur Vereinfachung des Zusammenbaus der erfindungsgemäßen Hubkolbenpumpe bilden die Bauteile Joch, erstes Gehäusebauteil, Kolben, Zylinder, Ventilsitz, Kugel, Feder, Kernflansch und zweites Gehäusebauteil eine vormontierbare Patrone, die in eine mit Kunststoff umspritzte Baugruppe gefügt ist, wobei die umspritzte Baugruppe aus der Spule, dem Eisenrückschluss und der Polplatte besteht.To simplify the assembly of the reciprocating pump according to the invention, the components yoke, first housing component, piston, cylinder, valve seat, ball, spring, core flange and second housing component form a preassembled cartridge which is joined in a plastic-molded module, the overmolded assembly of the coil which consists of iron yoke and pole plate.
Diese Patronenbildung ist besonders dann vorteilhaft, wenn sich die Zahl der Montageschritte wegen der stofflichen Trennung zwischen dem Joch und dem anschlussseitigen Gehäusebauteil einerseits und zwischen dem Kernflansch und anderen anschlussseitigen Gehäusebauteil im Vergleich zu den einstückigen Ausführungen erhöht.This cartridge formation is particularly advantageous when the number of assembly steps increases due to the material separation between the yoke and the connection-side housing component on the one hand and between the core flange and other connection-side housing component in comparison to the one-piece designs.
Die möglichen vorteilhaften Verfahren zum Zusammenbau sind weiter unten ausführlich beschrieben.The possible advantageous methods of assembly are described in detail below.
Erfindungsgemäße Hubkolbenpumpen finden in Heizungsanlagen von Kraftfahrzeugen zur Förderung und Dosierung von Brennstoff Anwendung, außerdem in mobilen Abgasreinigungsanlagen zur Dosierung von zusätzlichem Treibstoff oder zur Dosierung von flüssigen Reaktionsmitteln bei dem Betrieb von Katalysatoren zur Reduzierung von Stickstoffoxiden.Inventive reciprocating pumps are used in heating systems of motor vehicles for conveying and metering of fuel application, also in mobile emission control systems for metering additional fuel or for metering of liquid reactants in the operation of catalysts for the reduction of nitrogen oxides.
