Title: ANALYZING A PUMP TO DETERMINE VALVE WEAR AND WASHOUT USING A SELF-ORGANIZING MAP
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.
