How To Detect Faults in A Rotary Drilling Rig

In engineering construction, the normal operation of rotary drilling RIGS is of vital importance. Timely detection of faults can prevent delays in the project schedule. Here are several key detection points for you:

1. Check the engine condition: When starting, observe whether the speed is stable. During operation, pay attention to any abnormal shaking or abnormal noise. If the speed fluctuates and black smoke is emitted, it may be a problem with the fuel system or the cylinder.

2. Check the hydraulic system: Inspect whether there is any oil leakage at the connection points of the hydraulic oil pipes, whether the hydraulic oil level is within the standard range, and feel whether the hydraulic power has weakened when operating the handle. If the power is insufficient, it may be a fault of the pump or valve.

3. Inspect the drill bit and drill pipe: Check the degree of wear on the tip of the drill bit teeth, whether there are any cracks or damages, and then inspect whether the connecting bolts of the drill pipe are loose. If the drill bit is severely worn or the connection is loose, it will affect the hole-forming efficiency.

4. Test the electrical system: Open the instrument panel to observe if the indicator lights are normal. Use a multimeter to check if the circuit connections are good. If the instrument display is abnormal or some functions fail, it may be a short circuit or component damage.

5. Test the operating system: Operate each control button and joystick to feel if there is any lag or slow response. At the same time, observe whether the parameters on the display screen are accurate. If the system response is not sensitive, it may be due to sensor or program failure.

6. Listen for abnormal noises from the entire machine: When idling, get close to the equipment and listen. Pay special attention to parts such as the transmission and reducer. If there are sounds of metal friction or impact, stop the machine immediately to check the wear of internal parts.

Conclusion: Detecting faults in rotary drilling RIGS requires starting from multiple systems and making a comprehensive judgment through methods such as "observing, checking, inspecting, measuring, testing, and listening". Regularly conducting these inspections can help identify potential problems in a timely manner, ensure the efficient and safe operation of the equipment, and prevent construction losses caused by malfunctions.
