How To Inspect The Electrical Components (such As Sensors) of Second-hand Rotary Drilling RIGS? Avoid Later Malfunctions

The electrical components of rotary drilling RIGS, especially sensors, are the "nerve endings" for the precise operation of the equipment. The condition of such components in second-hand equipment is complex, and a detailed inspection is required during machine inspection to avoid future malfunctions.

1. Appearance integrity inspection: Check whether the sensor housing is damaged or deformed, and whether the wiring ports are rusted or loose. A damaged casing may cause the internal components to become damp, affecting signal transmission.

2. Line connection inspection: Sort along the sensor line to check if the cable is aged, damaged or has loose connections at the joints. Line problems are prone to cause signal interruption, leading to false alarms of equipment faults.

3. Function power-on test: Start the drilling rig and observe whether the corresponding sensor data on the instrument panel is displayed normally, such as whether the values of the pressure and Angle sensors are stable. Data jumps or no display may indicate sensor failure.

4. Compatibility matching confirmation: Check whether the sensor model matches the brand and model of the drilling rig. Sensors of different specifications may have differences in signal protocols, which may prevent them from working properly.

5. Historical Fault Query: Retrieve the historical fault records of sensors through the equipment control system. Sensors that frequently report errors may have hidden defects and require focused assessment.

6. Protection performance verification: Check whether the waterproof and dustproof seals of the sensor are in good condition. Especially for equipment operating in damp and dusty environments, seal failure will significantly shorten its lifespan.

In conclusion, when inspecting the electrical components (such as sensors) of second-hand rotary drilling RIGS, it is necessary to take into account multiple aspects including appearance, wiring, functionality, and compatibility. Only by comprehensively identifying potential hazards can the risk of future malfunctions be reduced and the stable operation of the equipment be ensured.
