Valve failure determination in a pump monitoring system

A method of identifying a failure of a specific valve in a pump, the method comprising:

• identifying, by a processor, a pump section as failed by detecting irregularities in a strain signal;
• correlating, by the processor, the strain signal to an internal pump pressure;
• determining, by the processor, whether the internal pump pressure corresponds to a pressure associated with a first valve determined via a pressure transducer at the first valve;
• and
• displaying an indication that the first valve in the pump section has failed in response to determining that the internal pump pressure corresponds to the pressure associated with the first valve.

A non-transitory computer-readable medium that includes instructions that are executable by a processor for causing the processor to perform operations for identifying a failed valve in a pump associated with a wellbore, the operations comprising:

• identifying a first valve in a pump section as failed by detecting irregularities in a strain signal;
• correlating the strain signal to an actual discharge pressure in the pump section using a discharge pressure signal;
• correlating the strain signal to an actual suction pressure in the pump section using the suction pressure signal;
• determining whether a pump pressure corresponds to the actual suction pressure or the actual discharge pressure using the strain signal;
• displaying an indication that a suction valve in the pump section has failed in response to determining the pump pressure corresponds to the actual suction pressure;
• and
• displaying an indication that a discharge valve in the pump section has failed in response to the pump pressure corresponds to the actual discharge pressure.
