Pump integrity detection, monitoring and alarm generation

A system for pressurizing fluid comprising:

• a fluid pump comprising an internal component and a discharge in communication with a borehole;
• at least one sensor that is responsive to vibrations of the pump, that is responsive to vibrations of the internal component, and that is strategically located to be sensitive to the vibrations of the internal component;
• and
• a processor configured to perform:
• receiving time domain measurement data from the at least one sensor, the measurement data indicating the vibrations occurring in the fluid pump and vibrations of the internal component;
• filtering the measurement data to remove measurement data components associated with cyclical motions of the fluid pump;
• dividing the filtered measurement data into a plurality of subsets, each subset corresponding to a pump cycle;
• estimating a peak count for each subset, the peak count being a number of peaks having an amplitude that exceeds a selected amplitude threshold, the amplitude threshold associated with impacts of the internal components;
• comparing the peak count with an expected peak count;
• determining whether the internal component is in a condition selected from at least one of a wear condition and a failure condition based on the comparison;
• and
• indicating a wear condition when it is determined that the internal component is in a wear condition, and indicating a failure condition when it is determined that the internal component is in a failure condition so that an operation of the pump is changed based on what is indicated.
