Abstract

The membrane pump is operated by a power unit (4) in the form of an oil engine driving a reciprocating piston (5) via a connecting rod. It can displace hydraulic fluid in a working space (6) against a membrane (7). The unit (4) is controlled by the action of valves and responding to pressure in the space (6) above the piston until the piston returns to zero. USE/ADVANTAGE - A pump for the delivery of abrasive and highly viscous slurries with high concentrations of solids offering a favourable working volume suitable for feeding filter presses.

Description

Die Erfindung betrifft eine Membranpumpe, bei der die Membran unter Zwischenschaltung einer Hydraulikflüssig­ keitsvorlage von einem sich hin- und herbewegenden Ar­ beitskolben beaufschlagt wird. Der Antrieb des Arbeits­ kolben erfolgt über einen Kurbelantrieb mit einem Ölmotor.The invention relates to a diaphragm pump in which the Membrane with the interposition of a hydraulic fluid template of a floating ar is applied to the piston. The drive of work piston is made using a crank drive with a Oil engine.

Bei Erreichen des Betriebsdruckes im Arbeitsraum wird die Druckölzuführung zum Ölmotor auf drucklosen Umlauf gestellt. Von einem Kolben können eine oder zwei Mem­ brane beaufschlagt werden. Solche Kolbenmembranpumpen sind insbesondere geeignet zur Förderung von abrasiven und hochviskosen Schlämmen mit hoher Feststoff-Konzen­ tration. Sie werden beispielsweise zur Beschickung von Filterpressen eingesetzt.When the operating pressure in the work area is reached the pressure oil supply to the oil motor on unpressurised circulation posed. One or two Mem brane. Such piston diaphragm pumps are particularly suitable for the promotion of abrasive and highly viscous slurries with high solid concentrations tration. For example, they are used to load Filter presses used.

Die Aufgabe der Erfindung besteht darin, den Antrieb und die Ansteuerung einer Membranpumpe der eingangs genannten Art insbesondere auf das Bauvolumen günstiger zu gestalten.The object of the invention is the drive and the control of a diaphragm pump at the beginning mentioned type in particular on the construction volume cheaper to design.

Zur Lösung dieser Erfindungsaufgabe ist eine Membran­ pumpe, gekennzeichnet durch einen hydraulisch angetrie­ benen Arbeitskolben, der nach einer bevorzugten Aus­ führungsart über den Betriebsdruck im Arbeitsraum oder im Förderraum bis zur Nullmenge des Druckmittelförder­ stromes steuerbar ist.A membrane is used to solve this invention task pump, characterized by a hydraulic drive benen piston, according to a preferred Aus type of guidance via the operating pressure in the work area or  in the delivery chamber up to the zero quantity of pressure medium delivery current is controllable.

Die anliegende Abbildung zeigt in prinzipieller Dar­ stellungsweise einen Längsschnitt durch eine solche Kolbenmembranpumpe.The attached figure shows in principle Dar in places a longitudinal section through one Piston diaphragm pump.

Über 2/2-Wegeventil 1 und Umschaltventil 2 wird von einer nicht dargestellten Druckmittelversorgung der Ölmotor 4 angetrieben.The oil motor 4 is driven by a pressure medium supply (not shown ) via a 2/2-way valve 1 and a changeover valve 2 .

Der Ölmotor treibt über einen Kurbelbetrieb 3 den Ar­ beitskolben 5 hin und her. Im Vorlauf drückt der Ar­ beitskolben 5 die Hydraulikflüssigkeit 6 gegen die Membrane 7. Die Membrane bewegt sich in den Pumpen­ gehäuseraum 10. Über Druckventil 9 wird das Medium in die Druckleitung 16 gefördert.The oil motor drives the Ar beitskolben 5 back and forth via a crank mechanism 3 . In advance, the Ar press piston 5 the hydraulic fluid 6 against the membrane 7th The membrane moves in the pump housing space 10 . The medium is conveyed into the pressure line 16 via the pressure valve 9 .

Gleichzeitig wird über Saugventil 13 das Medium in das Pumpengehäuse 15 gesaugt.At the same time, the medium is sucked into the pump housing 15 via the suction valve 13 .

Beim Umkehren des Kolben 5 wird durch die Hydraulik­ flüssigkeit 11 und die Membrane 12 das Medium über Druckventil 14 in die Druckleitung 16 gefördert. Wird der eingestellte Betriebsdruck erreicht, schaltet Ven­ til 2 die Hydraulikpumpe auf drucklosen Umlauf.When the piston 5 is reversed, the hydraulic fluid 11 and the membrane 12 convey the medium via pressure valve 14 into the pressure line 16 . If the set operating pressure is reached, valve 2 switches the hydraulic pump to unpressurized circulation.

Fällt in der Druckleitung 16 der Druck, schaltet Ventil 2 wieder um und die Kolbenmembranpumpe arbeitet wieder.If the pressure in the pressure line 16 drops, valve 2 switches over again and the piston diaphragm pump works again.
