摘要
A pump for pumping fluid includes a pressure sensor disposed in the discharge outlet that communicates with a plurality of pumping chambers. The pressure sensor monitors the discharge pressure and transmits the discharge pressure to a logic device. The logic device is configured to analyze the discharge pressure verses time, determine a peak-to-peak amplitude associated with the discharge pressure verses time, and to detect a pressure spike corresponding to the maximum or high peak-to-peak amplitude. The pressure spike may correspond to uncharacteristic operation of a discharge valve or a suction valve associated with the pump.
