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, designed to help you keep your equipment in optimal condition:

• Regular Inspection: Check ZJ-40DB winch drive shaft cardan shafts, ZJ70DB brake pads, and Boiler WNS2-1.25-Y smoke temperature controllers every 65 operating hours; inspect sealing parts (O-Ring P1000168AA) and filters (Oil Filter B7685) for wear or clogging, and replace them in time to avoid system failure.

• Cleaning & Lubrication: Keep winch drive shaft cardan shafts, gear components (Gear P3000004AA), and bearings (4301000470) clean; apply appropriate lubricating oil to reduce friction and prevent rust and wear. For hydraulic valves and solenoid valves, ensure the hydraulic oil is clean and replace it regularly.

• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially electrical components, seals, and boiler parts). For explosion-proof equipment (explosion-proof walkie-talkie GP328) and high-pressure 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 stainless steel cotter pins 420703023804005000 properly to prevent damage). For drilling rig components, boiler parts, and generator parts, follow OEM installation guidelines to ensure compatibility and safety.

• Electrical & Sensor Maintenance: Regularly check boiler smoke temperature controllers (WRNX-320) and thermocouples for accurate temperature measurement; inspect aviation plug connectors (Baoji Youtai 60YT-3P+E-60A) for loose connections; clean electrical components to prevent dust accumulation and short circuits.

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: Cardan Shaft Wear in ZJ-40DB Drilling Rig

A customer’s ZJ-40DB drilling rig experienced winch power loss and abnormal noise due to worn universal joints on the winch drive shaft cardan shaft (G303.4.0 L1595±75). We supplied the ZJ-40DB Winch Drive Shaft Cardan Shaft, which is fully compatible with the rig. After replacement, the winch operated smoothly, power transmission was stable, and the rig resumed drilling operations, reducing downtime by 85%.

Case 2: Smoke Temperature Controller Malfunction in Boiler WNS2-1.25-Y

An industrial plant’s WNS2-1.25-Y boiler had unstable combustion and inefficient fuel consumption due to a faulty smoke temperature controller and thermocouple (WRNX-320). We provided the Boiler WNS2-1.25-Y Smoke Temperature Controller & Thermocouple WRNX-320, which fits perfectly with the boiler. After replacement, the boiler’s smoke temperature was accurately monitored, combustion efficiency improved by 25%, and fuel consumption was reduced significantly.

Case 3: Brake Pad Wear in ZJ70DB Drilling Rig

A drilling team’s ZJ70DB drilling rig had reduced braking performance due to worn brake pads (BK-1-7A), risking safety during winch operation. We supplied the ZJ70DB Brake Pads BK-1-7A, which are compatible with the rig’s disc brake system. After replacement, the braking force was restored to normal, ensuring safe winch operation, and maintenance costs were reduced by 70% compared to replacing the entire brake assembly.
