Description

Einrichtung zur Abbildung der Hublänge von Dosierpumpen.Device for mapping the stroke length of metering pumps.

Die Erfindung betrifft eine Einrichtung, die Hublänge von Dosierpumpen mit stellbarer Hublänge als übertragbares Signal abzubilden.The invention relates to a device that increases the stroke length of metering pumps with an adjustable stroke length as a transferable one Map signal.

Die bekannten Einrichtungen zur Abbildung der Hublänge von Dosierpumpen sind selbständige Funktionsgruppen, die die Umwandlung des für die Hublänge der Pumpe charakteristischen Parameter in ein Abbildungssignal zur Fernübertragung übernehmen.The known devices for mapping the stroke length of metering pumps are independent functional groups that the Conversion of the parameter characteristic of the stroke length of the pump into a mapping signal for remote transmission take over.

Diese Funktionsgruppen sind als Rückmeldebaugruppen bzw. Stellungsgeber bekannt.These function groups are available as feedback modules or Position transmitter known.

Das Ziel der Erfindung ist es, den Fertigungs- und Materialaufwand für Abbildungseinrijhtungen zu minimieren.The aim of the invention is to reduce the manufacturing and material costs for imaging devices to minimize.

Die Aufgabe der Erfindung besteht darin, die Abbildung der Stellgröße Hublänge ohne funktionell selbständige Baugruppen zu realisieren.The object of the invention is to map the manipulated variable stroke length without functionally independent assemblies to realize.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß ein am Pumpentriebwerk angeordnetes bekanntes mechanisches Anzeigegetriebe auf der der Skale gegenüberliegenden Seite mit einem Widerstandsferngeber versehen ist.According to the invention the object is achieved in that an am Well-known mechanical display gear arranged on the side opposite the scale with pump drive a resistance transmitter is provided.

Die Erfindung wird an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail using an exemplary embodiment.

Die Zeichnung zeigt ein Anzeigegetriebe mit Widerstandsferngeber. The drawing shows a display gear with resistance teletransmitter.

Das mechanische Anzeigegetriebe 1 für die Hublänge wird in allen Dosierpumpen verwendet. Es übernimmt die Anzeige der vor Ort eingestellten Hublänge. Es untersetzt die Anzahl Umdrehungen xQ der Stellspindel in einem bestimmten Anzeigewinkel oL £ von 330°· Zeiger und Skale 2 übernehmen die Darstellung.. The mechanical indicator gear 1 for the stroke length is used in all metering pumps. It takes over the display of the stroke length set on site. It reduces the number of revolutions x Q of the adjusting spindle in a certain display angle oL £ of 330 ° · Pointer and scale 2 take over the representation.

Erfindungsgemäß ist auf der der Skale 2 gegenüberliegenden Seite des Anzeigegetriebes 1 ein Widerstandsferngeber 3 zur Abbildungssignalgewinnung angeordnet. Der Antriebswinkel Λ des Widerstandsferngebers 3 beträgt 270°.According to the invention, on the side of the display gear 1 opposite the scale 2, a resistance teletransmitter 3 is used Imaging signal acquisition arranged. The drive angle Λ of the resistance transmitter 3 is 270 °.

Zur Übereinstimmung von Antriebswinkel Ot ? und Anzeigewinkel Öl « wird das Übersetzungsverhältnis des Anzeigegetriebes 1 verändert, so daß bei der Anzahl der UmdrehungTo match the drive angle Ot ? and display angle oil «, the gear ratio of the display gear 1 is changed so that the number of revolutions

der Stellspindel χ der Abbildungssignnlhereich sowie der Anzeigebereich voll erfaßt wird.the adjusting spindle χ the image signal area and the display area are fully covered.

Der Vorteil der Erfindung besteht darin, daß das modifizierte mechanische Anzeigegetriebe 1 die Punktion der bisher üblichen Rückmeldebaugruppen bzw. Stellungsgeber übernimmt, wodurch die Ziel- und Aufgabenstellung der Erfindung voll erreicht wird.The advantage of the invention is that the modified mechanical display gear 1 is the puncture of the previously takes over the usual feedback modules or position transmitter, whereby the aim and object of the invention is fully achieved.
