Abstract

Bei einem Verfahren zur Überwachung und zur automatischen Störungsfrüherkennung der Ventile, insbesondere der Saug- und/oder Druckventile, einer oszillierenden Verdrängerpumpe, insbesondere einer Membrandosierpumpe, ist erfindungsgemäß vorgesehen, daß das von einem undichten Ventil aufgrund der Rückströmung des Förderfluids im geschlossenen Ventilzustand erzeugte erhöhte Betriebsgeräusch als Maß für die Undichtigkeit des Ventils verwendet wird, indem der erzeugte Effektivsignalpegel kontinuierlich überwacht und mit einem vom Betriebsgeräusch der Pumpe mit intaktem Ventil gebildeten Referenzsignalpegel verglichen wird, wobei bei einer vorbestimmten Pegelabweichung bzw. - veränderung aufgrund eines erhöhten Betriebsgeräusches eine Störungsfrüherkennungsanzeige ausgelöst wird.In a method for monitoring and automatic early fault detection the valves, in particular the suction and / or pressure valves, an oscillating Positive displacement pump, in particular a diaphragm metering pump, is according to the invention provided that by a leaking valve due to the Backflow of the delivery fluid in the closed valve state increased Operating noise is used as a measure of the leakage of the valve by: the generated effective signal level continuously monitored and with one of the operating noise The reference signal level formed by the pump with the valve intact is compared, wherein at a predetermined level deviation or Change due to an increased operating noise a fault early detection indicator is triggered.

Die Erfindung betrifft außerdem eine zur Durchführung dieses Verfahrens vorgesehene Vorrichtung, die eine entsprechende Meßeinrichtung (5), insbesondere in Form eines den erzeugten Körperschall messenden Schwingungsbeschleunigungssensors, sowie eine Vergleichseinrichtung (7) aufweist.
