Description

Hydraulisch betätigte MembranpumpeHydraulically operated diaphragm pump

Membranpumpen eignen sich im Gegensatz zu Kolbenpumpen besser zur Förderung von aggressiven und hochviskosen Flüssigkeiten, weil keine mechanische Reibung zwischen beweglichen Teilen stattfindet. In contrast to piston pumps, diaphragm pumps are better suited to pumping aggressive and highly viscous liquids because there is no mechanical friction between moving parts.

Die Membrane wird auf der einen Seite durch Hydraulikflüssigkeit beaufschlagt und auf der anderen Seite wird die zu fördernde Flüssigkeit verdrängt. Dabei wird praktisch die gleiche Menge der Flüssigkeit gefördert wie Hydraulikflüssigkeit zugeführt wird. Durch die symmetrische Anordnung der zwei Membranen, die wechselweise beaufschlagt werden, wird eine gleichmäsige Förderung erreicht.The diaphragm is pressurized by hydraulic fluid on one side and the fluid to be pumped is displaced on the other side. In this case, practically the same amount of fluid is pumped as the hydraulic fluid is supplied. The symmetrical arrangement of the two diaphragms, which are pressurized alternately, ensures uniform pumping.

Die zum Betrieb erforderliche Hydraulikflüssigkeit wird durch eine im Druck und in der Fördermenge steuerbare Hydraulikpumpe geliefert.The hydraulic fluid required for operation is supplied by a hydraulic pump whose pressure and flow rate can be controlled.

Die Figur 1 zeigt eine Ausführung einer Doppel-Membranpumpe. Die Membrane 1 ist außen zwischen dem Gehäuse 2 und dem Gehäusedeckel 3 fest eingespannt. Zentral wird die Membrane durch zwei Flansche k und 5 zusammengespannt und durch die mit diesen Flanschen fest verbundene Führungsstange 6 im Gehäusedeckel j> axial beweglich geführt. Die Membrane 1 trennt die beiden Arbeitsräume 7 und 8. Der Arbeitsraum 8 wird durch das Ventil 9 mit dem Einlaßraum 10 und durch das Vintil 11 mit dem Druckraum 12 für die zu fördernde Flüssigkeit verbunden. Der Arbeitsraum 7 wird über den Steuerschieber 20 mit Hydraulikflüssigkeit versorgt. In der hier gezeigten Version Figure 1 shows a design of a double diaphragm pump. The diaphragm 1 is firmly clamped on the outside between the housing 2 and the housing cover 3. The diaphragm is clamped together centrally by two flanges k and 5 and is guided axially movably in the housing cover j> by the guide rod 6 firmly connected to these flanges. The diaphragm 1 separates the two working chambers 7 and 8. The working chamber 8 is connected to the inlet chamber 10 by the valve 9 and to the pressure chamber 12 for the liquid to be pumped by the valve 11. The working chamber 7 is supplied with hydraulic fluid via the control slide 20. In the version shown here

wird der Steuerschieber 20 über 2 Magnete und 22 betätigt, die über die beiden Microschalter 25 und 2k von der Membranpumpe gesteuert werden. Es ist aber auch möglich, daß der Kolben 26 des Steuerschiebers 20 direkt über eine mechanische Verbindung von den beiden Führungsstangen 5 und 5' gesteuert wird. Die zum Betrieb erforderliche Hydraulikflüssigkeit wird durch eine (hier nicht dargestellte) im Druck und in der Fordermenge steuerbare Hydraulikpumpe über die Zuleitung 25 im Steuerschieber 20 geliefert.the control slide 20 is actuated by two magnets and 22 , which are controlled by the diaphragm pump via the two microswitches 25 and 2k . It is also possible, however, for the piston 26 of the control slide 20 to be controlled directly by a mechanical connection from the two guide rods 5 and 5'. The hydraulic fluid required for operation is supplied by a hydraulic pump (not shown here) whose pressure and delivery rate can be controlled via the supply line 25 in the control slide 20.
