Abstract
A system obtains sensor data that includes: first vibration data related to vibration of an inlet manifold of a pump of a hydraulic fracturing rig, pump speed data related to a speed of the pump, pressure data related to a pressure of an outlet manifold of the pump, second vibration data related to vibration of a packing of the pump, and leakage data related to a leakage of fracturing fluid by the packing. The system processes the first vibration data and the pump speed data to determine that an inlet valve of the pump and an outlet valve of the pump have not failed, and thereby processes the pressure data to determine that the packing of the pump has failed. The system determines, based on at least one of the second vibration data and the leakage data, a failure severity level associated with the packing of the pump.
