AI Technical Summary
⚠Technical Problem
Reciprocating pumps experience wear and tear in their fluid end packing, leading to leakage and reduced operational efficiency, which can cause downtime and failure of the pump and associated hydraulic fracturing rigs.
⚗Method used
A system comprising an insert, a sensor, and a controller is used to detect wear in the fluid end packing by monitoring vibration data, determining if the wear level satisfies a predefined threshold based on the contact between the plunger and the insert.
🎯Benefits of technology
The system allows for timely maintenance of the fluid end packing, reducing downtime and preventing damage to other components by alerting operators when wear exceeds a threshold, thus improving pump performance and longevity.

Abstract
A system for detecting wear in a fluid end packing of a reciprocating pump is disclosed. The system includes an insert, a sensor, and a controller. The insert is associated with an annular seal ring of the fluid end packing. The annular seal ring defines a sealing interface with a plunger of the reciprocating pump. The sensor is configured to obtain vibration data associated with the fluid end packing. The controller configured to receive, from the sensor, the vibration data associated with the fluid end packing. Further, the controller is configured to determine, based on the vibration data being within a predefined range of vibration indicative of a contact of the plunger with the insert, that a wear level of the fluid end packing satisfies a wear threshold.
