On-Site Fault Maintenance Cases
Below are 3 real on-site fault cases, featuring practical solutions to help you quickly resolve common issues with our products, minimizing downtime and reducing maintenance costs:
Case 1: 4900350092 Manual Reversing Valve Sticking
Fault Phenomenon: A ZJ-30C drilling rig hydraulic system failed to reverse direction, with the 4900350092 manual reversing valve handle sticking and difficult to operate. Inspection: The valve core was clogged with hydraulic oil impurities, and the valve stem was lacking lubrication. Solution: Disassemble the valve, clean the valve core and valve body with a neutral cleaning agent, add lubricating oil to the valve stem, and reassemble the valve. Result: The valve handle operated smoothly, and the hydraulic system could reverse direction normally, with no further sticking issues within 7 months.
Case 2: 2159mm MS1952SS PDC Drill Bit Cutter Wear
Fault Phenomenon: An oil drilling operation experienced a significant drop in drilling efficiency, with the 2159mm MS1952SS PDC drill bit failing to cut through formations effectively. Inspection: The PDC cutters on the drill bit were severely worn (wear thickness ≥ 4mm), and the waterways were clogged with cuttings. Solution: Replace the worn drill bit with a new 2159mm MS1952SS PDC drill bit, clean the drilling fluid system to prevent further clogging. Result: Drilling efficiency was restored to 15-20m/h, and the drill bit operated stably for the entire drilling section.
Case 3: Boiler WNS2-1.25-5Y Fan Motor Overheating
Fault Phenomenon: A WNS2-1.25-5Y boiler fan motor TIPO 52/58 IP55 overheated, with the motor casing temperature exceeding 120°C, triggering an overheat protection shutdown. Inspection: The motor’s cooling fins were clogged with dust and debris, and the bearings were lacking lubrication. Solution: Clean the cooling fins with compressed air, add lubricating oil to the bearings, and check the motor wiring for loose connections. Result: The motor temperature dropped to normal (≤ 80°C), and the boiler operated stably without further overheat shutdowns.
