On-site Fault Maintenance Case
Case 1: A drilling team encountered a sudden drop in hydraulic pressure in the SJ Petro ZJ40 drilling rig’s two bank valve lines (Z07060200001AA) during geological prospecting operations, leading to slow valve operation and affecting drilling efficiency. On-site inspection found that the Z1"X3/8" bushing (QBJ10010302) had thread wear and loose connection, causing hydraulic oil leakage, and the combined washer 33 (P6300176AA) was deformed, further worsening the leakage. The root cause was frequent disassembly of the bushing during routine maintenance, leading to thread wear, and failure to replace the combined washer on schedule. The solution was to replace the worn bushing and deformed combined washer with the matching models in this catalog, apply thread sealant to the bushing, and tighten it to the specified torque. After reassembly, the hydraulic pressure returned to normal, and no leakage occurred within the subsequent 2 months. This case highlights the importance of replacing worn sealing and connecting parts on schedule and using proper installation torque.
This maintenance process complies with the fault handling guidelines for hydraulic pipeline leakage specified in API 6D and EN 12516-1, ensuring the safety and reliability of the equipment after maintenance.
FAQ (Frequently Asked Questions)
No. | Questions | Answers |
1 | Are all these accessories fully compatible with the SJ Petro ZJ40 two bank valve lines (Z07060200001AA)? | Yes, all accessories are specially designed and produced for the SJ Petro ZJ40 two bank valve lines (model: Z07060200001AA). Each part’s model and size strictly match the original equipment, ensuring perfect compatibility. They also comply with API 6D and EN 12516-1 standards, guaranteeing stable connection, tight sealing, and safe operation. |
2 | How often should key wearing parts (hoses, sealing rings) be replaced to avoid valve line failure? | Under normal drilling conditions (8 hours a day, 5 days a week), hose assemblies should be replaced every 12 months, sealing rings every 3-6 months, and combined washers every 8 months. If working in harsh environments (high dust, high temperature, frequent high-pressure operations), shorten the replacement cycle by 30% to prevent unexpected leakage or failure. |
3 | What should I do if hydraulic oil leaks from the valve line connections? | First, stop the equipment immediately and cut off the hydraulic supply to avoid oil waste and equipment damage. Then identify the leakage point: check if bushings/fittings are loose or worn, sealing rings are deformed or cracked, or hoses are damaged. Tighten loose components, replace worn/ damaged parts with matching models from this catalog, and apply thread sealant if needed. After reassembly, test the system for leakage before resuming operation. |
