On-Site Fault Repair Cases

Below are three real on-site fault repair cases, showing how our products solve practical problems for users, reduce downtime, and improve operational efficiency. All cases are from actual application scenarios in oil drilling and heavy machinery industries:

Case 1: ZJ-20 Drill Rig Air System Failure

Equipment: ZJ-20 drill rig (air system)
Fault: The drill rig’s air control system fails, and the drill bit cannot move normally, resulting in downtime during drilling operations.
Diagnosis: After on-site inspection, the Shuttle Valve 810699-00-0015 is blocked by impurities, causing air flow to be unable to switch normally, leading to the failure of the air control system.
Repair: Replace the blocked shuttle valve with our 810699-00-0015 Shuttle Valve, clean the air pipeline, and test the air flow switching function.
Result: The air control system returns to normal, the drill bit operates smoothly, and the downtime is controlled within 45 minutes. The shuttle valve has been in stable operation for 400 hours without reoccurrence of the fault, avoiding economic losses caused by prolonged downtime.

Case 2: BOMCO Pump Piston Rod Wear Failure

Equipment: BOMCO pump (equipped with AH0000060105 piston rod)
Fault: The pump leaks hydraulic oil severely, and the output pressure drops, affecting the normal operation of the hydraulic system.
Diagnosis: The piston rod AH0000060105 is severely worn, causing the piston seal to fail and hydraulic oil to leak.
Repair: Replace the worn piston rod with our AH0000060105 Piston Rod (BOMCO pump), replace the piston seal 72219, and test the pump’s output pressure.
Result: The hydraulic oil leakage is completely eliminated, the pump’s output pressure returns to the rated value (30MPa), and the pump operates stably. The piston rod has been in use for 6 months without wear, ensuring the normal operation of the hydraulic system.

Case 3: Caterpillar Engine Alternator Failure

Equipment: Caterpillar engine (equipped with 4N-8216 alternator belt)
Fault: The engine’s alternator fails to generate power, causing the battery to be undercharged and the engine to fail to start normally after shutdown.
Diagnosis: The 4N-8216 Alternator Belt is cracked and broken, unable to transmit power from the engine to the alternator.
Repair: Replace the broken alternator belt with our Caterpillar 4N-8216 Alternator Belt, adjust the belt tension, and test the alternator’s power generation function.
Result: The alternator generates power normally (output voltage 24V), the battery is fully charged, and the engine starts smoothly every time. The alternator belt has been in use for 8 months without damage, ensuring the stable operation of the engine’s electrical system.
