Detailed Product Introduction

This ZJ30-DBS drilling rig parts collection covers all mission-critical subsystems: mud circulation valves and liners, hydraulic cylinders and motors, pneumatic control valves, brake system components, filtration parts, power transmission belts, pressure control valves, and specialized mud pump consumables. Each item is cross-referenced to the rig’s original part numbers, with standardized unit quantities tailored to the ZJ30-DBS configuration, eliminating fit errors and compatibility issues.
All pressure-containing and load-bearing components meet strict API and ISO certification requirements, ensuring compliance with global onshore drilling safety standards. The parts are curated for both minor field repairs and full rig overhauls, covering high-wear consumables (filters, seals, belts) and heavy-duty structural components (cylinders, valves, mud pump liners) to keep the ZJ30-DBS rig operating at peak performance.
Functional Performance & Value Highlights
- Uninterrupted Rig Uptime: OEM-matched parts reduce repair and replacement time by 45%, minimizing costly drilling downtime and lost operational revenue.
- Industry Compliance Assurance: API 7K, API 8C, and ISO/GOST certified components pass third-party pressure testing (up to 35 MPA for gate valves), meeting global drilling safety and quality mandates.
- Extended Service Life: High-grade alloy steel, wear-resistant rubber seals, and heat-treated hardware resist abrasion, corrosion, and hydraulic pressure, doubling the lifespan of generic aftermarket parts.
- Simplified Sourcing: Consolidated parts list covers all ZJ30-DBS subsystems, eliminating the need for multiple suppliers and streamlining inventory management.
Structural & Engineering Features
- Rig-Specific Precision Fit: Exact drop-in replacements for ZJ30-DBS original components, no custom machining or modification required for installation.
- High-Pressure Durability: Pressure-containing valves and cylinders rated for up to 35 MPA operating pressure, designed to handle the ZJ30-DBS’s mud circulation and hydraulic load demands.
- Wear-Resistant Materials: Mud pump liners and pistons use hardened alloy steel, seals use oil- and abrasion-resistant nitrile rubber, and valves feature reinforced sealing surfaces for mud service.
- Subsystem Segmentation: Parts grouped by mud pump, hydraulic system, pneumatic controls, brake system, and power transmission for targeted sourcing and troubleshooting.
Applicable Operating Conditions
- These ZJ30-DBS drilling rig parts are engineered forharsh onshore drilling environments tailored to the 3000-meter rig’s operational scope, including:
- Onshore oil and gas exploration drilling (3000m depth capacity)
- Geothermal and water well drilling operations with high mud circulation demands
- Remote land rig sites with high dust, temperature fluctuations, and limited maintenance access
- Heavy-duty continuous drilling operations (24/7 runtime) with high hydraulic and mud system loads
- API and GOST-compliant drilling projects requiring certified rig components
Professional Maintenance & Troubleshooting Recommendations
- Pre-Installation Inspection: Verify part certification labels, check for surface defects, and confirm dimensional accuracy to ensure pressure integrity and fit.
- Torque Specification Adherence: Use calibrated torque tools for valve flanges and hydraulic connections, following API Spec 7K torque values to prevent leaks and component failure.
- Consumable Replacement Schedule: Replace filters, seals, and belts every 1,000 drilling hours; inspect mud pump liners and pistons every 500 hours for wear.
- Pressure Testing Protocol: Conduct hydrostatic pressure testing on valves and cylinders post-installation to confirm 35 MPA pressure rating compliance.
- Lubrication Compliance: Use only specified lubricants (Spheerol EPL-2, PG-220) to maintain hydraulic and brake system performance, avoiding cross-contamination.

On-Site ZJ30-DBS Rig Fault Repair Cases
Case 1: Mud Pump Pressure Loss (Liner & Piston Failure)
A ZJ30-DBS rig experienced severe mud pressure loss during drilling, halting operations. Inspection revealed worn 5” mud pump liners and damaged piston seals. Replacing the OEM-spec liners (NB102.05.11.00) and pistons (NB102.05.09.00) from this parts list restored full mud pressure, resuming drilling within 3 hours.
Case 2: Hydraulic Bail Cylinder Leakage
The ZJ30-DBS rig’s hydraulic bail cylinder (p/n 1300127821) developed hydraulic fluid leaks, causing unstable hoist operation. Swapping the faulty cylinder with a certified replacement from this catalog eliminated leaks and restored smooth hoist functionality, avoiding a full rig shutdown.
Case 3: Pneumatic Control Valve Malfunction
Unresponsive pneumatic controls on the ZJ30-DBS rig were traced to a faulty KPJA-L15 pneumatic valve. Replacing the API-compliant valve restored full pneumatic system control, fixing operational delays and ensuring safe rig handling.
Frequently Asked Questions (FAQ)
| Question | Answer |
| Are these parts compatible only with the ZJ30-DBS rig, or other 3000m rigs? | These parts are exclusively designed for the ZJ30-DBS drilling rig, with factory-matched dimensions and specifications. They are not guaranteed to fit other 3000m rig models due to design variations. |
| Do all pressure-containing parts meet API and GOST certification standards? | Yes, all valves, cylinders, mud pump components, and pressure parts comply with API Spec 7K/8C, ISO 10631, and relevant GOST standards, with full certification traceability for drilling compliance. |
| Can I purchase individual parts for minor repairs, or only full kits? | Parts are available for individual subsystem purchase (mud pump, hydraulic, pneumatic, brake) to target specific repairs; bulk overhaul kits are also offered for full ZJ30-DBS rig refurbishment. |
