AI Technical Summary
In existing technologies, plug valves are difficult to accurately determine the timing of maintenance under ultrafine sand fracturing and testing conditions, leading to operation interruption or shutdown, and the grease injection efficiency is low.
Multiple monitoring devices (pressure sensor, torque sensor, image sensor, infrared thermal imager, and acoustic emission sensor) are used to monitor the operating status of the plug valve in real time. The control unit analyzes the data, judges and executes grease injection, cleaning and sand removal operations to achieve intelligent operation and maintenance.
It enables precise judgment of maintenance timing for plug valves, avoiding operation interruptions caused by untimely sand injection or grease injection, and improving operation efficiency.
