7. On-Site Fault Maintenance Cases

The following are three real on-site fault maintenance cases, providing practical reference for users to solve common problems:

7.1 Case 1: Winch YC3A-5864 Hoisting Failure

Fault Phenomenon: During oilfield hoisting operation, the winch YC3A-5864 cannot lift normally, and there is abnormal noise.
Cause Analysis: After inspection, the Circlip for shaft (420602021080160000) is worn and falls off, leading to loose connection of the winch drive shaft.
Solution: Replace the Circlip for shaft with a new one (model 420602021080160000), re-install and adjust the drive shaft, and apply lubricating oil.
Result: The winch returns to normal operation, and the hoisting efficiency is restored to the standard level, with no abnormal noise.

7.2 Case 2: Hydraulic System Leakage of ZJ70 Drilling Rig

Fault Phenomenon: The hydraulic system of ZJ70 drilling rig has oil leakage, and the pressure is unstable.
Cause Analysis: The Combination gasket (ZJ70DB Φ24) is aged and damaged, resulting in poor sealing.
Solution: Replace the Combination gasket with a new one (model ZJ70DB Φ24), clean the sealing surface, and ensure that the installation is in place.
Result: The oil leakage is completely eliminated, the hydraulic system pressure is stable (maintained at 25MPa), and the drilling rig operates normally.

7.3 Case 3: Inclinometer QDT Data Deviation

Fault Phenomenon: The Inclinometer QDT has large data deviation during angle measurement, affecting wellbore trajectory control.
Cause Analysis: The O-Ring (AS-016 981622) of the inclinometer is damaged, leading to dust and moisture entering the internal sensor.
Solution: Replace the O-Ring with a new one (model AS-016 981622), clean the sensor, and calibrate the inclinometer (calibration accuracy ±0.05°).
Result: The data deviation of the inclinometer is reduced to within ±0.1°, meeting the drilling operation requirements.
