Function Description

Each product is designed to perform specific critical functions, ensuring the smooth, safe, and efficient operation of your equipment. Here’s how our key parts work:

• ZJ50J Gearbox JS-1000: Serves as the core transmission component of ZJ50J drilling rigs, transmitting power from the engine to the drawworks, mud pump, and other key components, ensuring stable speed regulation and reliable power output.

• GNJB 15kW & NJ 15kW Mud Mixers: Mix drilling mud to the required consistency, ensuring uniform mixing of drilling fluid additives, which is critical for maintaining wellbore stability and efficient drilling operations. The SL30147 impeller enhances mixing efficiency and ensures consistent mud quality.

• Spring Return Safety Valve RRV3-5000U: Installed in drilling rig hydraulic systems, this valve automatically opens to release excess pressure (up to 5000PSI) and returns to the closed position once pressure is within the safe range, protecting hydraulic components from overpressure damage.

• ZJ70DB High-Pressure Hose BK-ABI-1400: Transmits high-pressure hydraulic fluid between components of ZJ70DB drilling rigs, ensuring leak-proof performance and reliable power transmission for hydraulic systems such as winches and brakes.

• Filters (1R0762, 1R0750, 5400200034): Remove impurities from diesel, hydraulic oil, and other fluids, protecting engine, hydraulic, and transmission components from wear and extending equipment service life.

• Clutch & Friction Parts (EK140103-010130, W18-07-900.01.02.06.07): Enable smooth engagement and disengagement of drilling rig clutches, transmitting power efficiently and ensuring safe control of equipment operation.

Maintenance & Care Suggestions

Proper maintenance is key to extending the service life of mechanical parts and reducing replacement costs. Here are practical, easy-to-follow suggestions tailored to our products:

• Regular Inspection: Check ZJ50J JS-1000 gearboxes, ZJ70DB high-pressure hoses, and safety valves (RRV3-5000U) every 75 operating hours; replace worn or damaged parts (such as O-rings 82.5X3.55 5300100224 and friction plates EK140103-010130) in time to avoid system failure.

• Cleaning & Lubrication: Keep mud mixer impellers (SL30147), bearings (F1000.GB276-64), and bushings (BK-3-6A1) clean; apply appropriate lubricating oil (matching the equipment manual) to reduce friction and prevent rust and wear.

• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially electrical components, O-rings, and filters). For high-pressure hoses and safety valves, store them in a cool, moisture-free environment to maintain their performance.

• Installation Notes: Ensure parts are installed correctly according to the equipment manual; avoid forced installation (e.g., aligning stud bolts AH1301010524 properly to prevent thread damage). For gearboxes and hydraulic components, check oil levels and seals before operation.

• Filter & Fluid Maintenance: Regularly replace filters (1R0762, 1R0750, 5400200034) to ensure the cleanliness of diesel and hydraulic oil; check Sullair pressure regulator switches (40694) for accurate pressure control and adjust as needed.

On-Site Fault Maintenance Cases

Here are 3 real on-site maintenance cases, showing how our parts solve practical problems for customers, reduce downtime, and improve equipment performance:

Case 1: Gearbox Failure in ZJ50J Drilling Rig

A customer’s ZJ50J drilling rig experienced power transmission failure due to a worn non-original JS-1000 gearbox, leading to complete drilling shutdown. We supplied our ZJ50J Gearbox JS-1000, which is fully compatible and made of high-strength alloy steel. After replacement, the drilling rig resumed normal operation, and the gearbox operated stably for 800 hours without issues, reducing downtime by 90%.

Case 2: Mud Mixer Impeller Wear in GNJB 15kW Unit

An oilfield’s GNJB 15kW mud mixer had reduced mixing efficiency due to a worn impeller, resulting in uneven mud consistency and delayed drilling operations. We provided the SL30147 Impeller, which is perfectly matched to the GNJB 15kW mixer. After installation, the mixer’s mixing efficiency improved by 40%, ensuring consistent mud quality and keeping drilling operations on schedule.

Case 3: Hydraulic Hose Leakage in ZJ70DB Drilling Rig

A ZJ70DB drilling rig’s hydraulic system had serious oil leakage due to a damaged high-pressure hose, affecting winch operation. We supplied the ZJ70DB High-Pressure Hose BK-ABI-1400, which is designed for high-pressure and high-vibration environments. After replacement, the leakage problem was completely solved, and the hydraulic system operated continuously for 500 hours without further issues.
