Abstract:
Examples of techniques monitoring pump health are disclosed. In one example implementation, a method may include: collecting, by a processing device, pump data about the pump, wherein the pump data comprises vibration data, timing data, and pressure data collected from vibration sensors, a timing sensor, and pressure sensors respectively; conditioning, by the processing device, the pump data by dividing the pump data into a plurality of segments, wherein each of the plurality of segments represents one completion cycle of the pump; analyzing, by the processing device, the plurality of segments of pump data to determine a valve and valve seat wear state of the pump using a self-organizing map generated from historical pump data; and changing, by the processing device, an operational parameter of the pump responsive to determining that the valve and valve seat wear state of the pump represents a risk level that is above a threshold.
Abstract:
A spray system includes a fluid source, a sprayer, a pump cylinder, a plunger, a pump motor, first and second inlet and outlet valves, a plurality of valve seals, a seal lubricant reservoir, and gravity fed seal lubricant lines. The pump cylinder is disposed fluidly between the fluid source and the sprayer. The plunger is situated within the pump cylinder and positioned by a displacement rod. The pump motor is configured to drive the displacement rod so as to reciprocate the plunger within the pump cylinder. The valve seals are disposed about the each of the first and second inlet and outlet valves. The lubricant seal lines carry seal lubricant from the reservoir to each of the valve seals.
Abstract:
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Verschleißüberwachung von Pumpen, bei dem vorteilhafterweise bei ruhender Pumpe ein definierter Pumpeneingangsdruck vorgegeben, mittels wenigstens einem Drucksensor, der in Förderrichtung vor und/oder hinter der Pumpe angeordnet ist, der Pumpeneingangsdruck und/oder der Pumpenausgangsdruck gemessen und zeitabhängig ein Druckverlauf vor und/oder nach der Pumpe ermittelt wird, über den auf den Pumpenverschleiß rückgeschlossen wird. Die vorliegende Erfindung bezieht sich weiterhin auf eine Pumpe zur Durchführung des erfindungsgemäßen Verfahrens, die ein Ventil und wenigstens einen in Förderrichtung vor und/oder nach der Pumpe angeordneten Drucksensor und eine dazugehörige Messeinrichtung zum Messen des Pumpeneingangsdrucks und/oder des Pumpenausgangsdrucks aufweist.
