Methods for Quickly Inspecting And Eliminating Faults of Rotary Drilling RIGS

Rotary drilling RIGS are prone to malfunction under complex working conditions. Rapid inspection and troubleshooting can minimize downtime and ensure construction progress to the greatest extent. Fault handling should follow the principle of "appearance first, then interior; simple first, then complex". Through systematic investigation, the root cause of the problem should be located to avoid secondary damage caused by blind disassembly.

1. First, check the power supply and hydraulic oil status: If there is no response upon startup, prioritize checking whether the battery wiring is loose, whether the power is sufficient, and whether the fuse has blown. In case of any abnormality in the hydraulic system, it is necessary to check whether the oil level meets the standard, whether the oil has deteriorated or been mixed with impurities. If the oil is turbid, the filter element should be replaced and cleaned immediately.

2. Check the sealing of pipelines and joints: In case of hydraulic oil leakage, focus on inspecting whether the pipelines are cracked, the joints are loose or the sealing parts are aged. Once the leakage point is found, replace the damaged parts in time. After replacement, exhaust the air and replenish the hydraulic oil to ensure the normal system pressure.

3. Check the causes of abnormal engine operation: If the engine has difficulty starting or unstable idling, first check whether the fuel supply is smooth and whether the fuel filter element is clogged. If there is abnormal noise, it is necessary to check the tightness of the belt, the wear of the bearings, and whether the oil level meets the standard to avoid insufficient lubrication causing malfunctions.

4. Analyze the causes of faults in the drilling system: When drilling is weak or the rotational speed is abnormal, first check whether the hydraulic motor is working properly and if there is any abnormal noise or leakage. Check again whether the drill pipe connection is firm and whether there are any foreign objects stuck in the drill bucket. If the drill pipe is deformed, it should be corrected or replaced in time to prevent it from breaking during operation.

5. Troubleshoot faults in the electrical control system: If the operation handle does not respond or moves slowly, first check whether the indicator lights on the control panel are normal and whether the line connections are loose. If sensor failure is involved, the fault code can be read through the built-in diagnostic system of the device. After locating the faulty sensor, it can be replaced or calibrated.

6. Check for abnormal issues in the walking system: If the equipment deviates or shows weakness during movement, first check if the tension of the tracks is appropriate and if there are any jamming or foreign objects. Check again whether the walking motor and the reducer are leaking oil and whether the gear oil is sufficient. If the output pressure of the motor is insufficient, the hydraulic components need to be repaired or replaced.

In conclusion, the rapid handling of faults in rotary drilling RIGS relies on a thorough understanding of the equipment structure and a standardized troubleshooting process. It is necessary to keep regular equipment maintenance records on a daily basis, accumulate experience in handling common faults, and accurately locate and promptly repair problems when they occur. This not only extends the service life of the equipment but also provides a reliable guarantee for the efficient progress of construction.
