Abstract

Die Erfindung betrifft eine Dosierpumpe mit rotierendem Antriebsmotor und oszillierendem Verdränger, bei der die Drehbewegung eines Antriebsmotors durch eine als Getriebe wirkende Anordnung in eine oszillierende Bewegung einer Schubstange umgesetzt wird, so dass ein durch diese betätigtes Verdrängungsorgan bei fortlaufend rotierendem Antriebsmotor eine oszillierende Linearbewegung durchführt, die in einem in der Längsachse der Schubstange angeordneten Dosierkopf in Zusammenwirken mit einem Auslass- und Einlassventil in abwechselnder Folge zu einem Pumphub (Druckhub) und einem Ansaughub und damit zu einer Förderung des Dosiermediums führt. Bei einer derartigen Dosierpumpe ist mit der Schubstange ein Bezugselement verbunden, dessen Position von einem Positionssensor abgetastet wird, wobei der Positionssensor ein Ist-Signal (xI) abgibt, welches zur Position des Bezugselements und damit des Verdrängungsorgans in einer festen Beziehung steht und mit dessen Hilfe Kenntnis über den Bewegungsablauf des Verdrängungsorgans gewonnen wird, so daß die elektronische Steuerung der Dosierpumpe auf Betriebszustände des Dosierkreises und der Pumpe reagieren kann.

Figure imgaf001
The invention relates to a metering pump with a rotating drive motor and oscillating displacer, in which the rotational movement of a drive motor is converted by an arrangement acting as a transmission in an oscillating movement of a push rod, so that an actuated by this displacement member with continuously rotating drive motor performs an oscillating linear motion, the in an arranged in the longitudinal axis of the push rod dosing in cooperation with an outlet and inlet valve in an alternating sequence to a pumping stroke (pressure stroke) and a suction stroke and thus leads to a promotion of the metering. In such a metering pump, a reference element is connected to the push rod whose position is sensed by a position sensor, wherein the position sensor outputs an actual signal (x I ), which is in a fixed relationship to the position of the reference element and thus of the displacement member and with its Help knowledge about the movement of the displacement member is obtained, so that the electronic control of the metering pump can respond to operating conditions of the dosing and the pump.
