Field Fault Repair Cases

Case 1: Drawworks Main Brake Failure – A ZJ10/1125CZ rig’s band-type main brake overheated and lost efficiency during heavy hoisting. Inspection found worn brake bands and blocked cooling water lines, caused by debris buildup. Solution: Replace brake bands, flush cooling lines, and adjust brake clearance per OEM specs. The brake performed reliably after repair, complying with API 4F safety standards.

Case 2: Hydraulic System Leakage – The rig experienced hydraulic pressure loss (below 14 MPa) due to leaking FKM seals in the hydraulic cylinders. Root cause was fluid contamination. Solution: Replace seals, flush the hydraulic system, and install high-efficiency filters. Pressure stability was restored, ensuring seamless operation of mast and drawworks.

FAQ

Question

Answer

What lubricant is recommended for the Allison-S5600DB transmission?

Use Allison TES 295-approved automatic transmission fluid (ATF). Replace every 1000 operating hours, and use only Allison-certified filters to prevent valve sticking, gear wear, and transmission failure, adhering to Allison’s maintenance guidelines.

How often should the drill line (Ø26mm, 8 lines) be replaced?

Replace per API 9B standards: if broken wires exceed 6 in a single lay or 10 in any 300mm length. For heavy-use scenarios, inspect weekly and rotate monthly to extend service life; typical replacement intervals range from 6–12 months.

How to resolve swivel (SL120) pressure leakage?

First, inspect FKM seals for wear or damage—replace if compromised. Flush internal components to remove debris, then test pressure integrity per API 7K. Ensure bearings are properly lubricated to prevent misalignment, which can cause seal damage.
