1. An apparatus comprising:
a fracturing pump, wherein the fracturing pump is a plunger pump having a power end, and a fluid end;
at least one sensor configured to detect fracturing pump operation data associated with a loading of a crankshaft of the fracturing pump by one or more connecting rods of the fracturing pump;
a crankshaft encoder configured to detect angular position data associated with an angular position of the crankshaft; and
a processor-based data analyzer configured to:
receive the fracturing pump operation data and the angular position data;
analyze the fracturing pump operation data in an angular domain based on correlating the fracturing pump operation data to the angular position data;
based on the analysis, diagnose wear of the crankshaft or estimate remaining life of the crankshaft; and
based on the diagnosis, perform a procedure to control operation of the fracturing pump.
