Maintenance & Care Recommendations

Proper maintenance of engineering parts is essential to extend their service life and ensure equipment performance. Below are practical, easy-to-follow maintenance suggestions tailored to our products:

• Regular Inspection: Check winch and brake components (115.33.03 Spring, KQ-08 Pin, Friction Disc W08-07-900), electrical parts (Starter 3066, Switch 330109031100100600), hydraulic valves (Rexroth Valve), and filters (NJU-250×180F) every 500 operating hours for signs of wear, cracks, leakage, or damage. Replace damaged parts promptly to avoid equipment failure, especially safety-critical components.

• Filtration System Maintenance: Replace filter elements (3827643, IX-160×80 2.4.03.005), oil suction filters (NJU-250×180F), and oil filters (FKQ1280-7 1/2) every 1000 operating hours or as recommended by the equipment manual. Clean filter housings regularly to prevent impurity buildup, which can damage pumps, valves, and other components.

• Lubrication: Apply appropriate lubricating oil to moving parts such as winch brake components, turntable square tiles, and working pliers (BG-80). Use lubricants that meet OEM specifications to reduce friction and wear, and avoid mixing different types of lubricants. Pay special attention to lubricating bushings (BK-3-7A) and pins (P2000671AA) to ensure smooth operation.

• Storage: Store spare parts in a dry, clean, and well-ventilated area. Avoid direct sunlight, high temperature, and humidity to prevent rust and aging. For electrical components (starters, switches) and explosion-proof parts (DWN-FBD 40W Lights), store them in anti-static, sealed packaging to protect their performance and safety.

• Professional Installation & Testing: Ensure parts are installed by trained maintenance technicians with experience in industrial equipment. Follow OEM installation guidelines to avoid incorrect installation, which can cause part damage or equipment malfunction. After installation, test the equipment to ensure the part is working properly—especially for electrical components and safety-critical parts like BOP components.

On-Site Fault Repair Cases

Below are 3 real on-site fault repair cases, showing how our parts solve practical problems for customers, minimize downtime, and reduce maintenance costs:

Case 1: ZJ70D Winch Brake Failure

Equipment: ZJ70D drilling rig winch brake system
Fault: The winch low-speed brake failed to return properly, leading to dragging and increased wear. The original brake shoe return spring (non-our product) was fatigued and lost elasticity.
Diagnosis: The original spring was made of low-quality material, which lost elasticity after long-term use under high pressure and vibration, causing the brake shoe to not return to its correct position.
Solution: Replaced with our ZJ70D Winch Brake Operating Mechanism Low-Speed Brake Shoe Return Spring 115.33.03, which features high elasticity and durable material. The spring was installed quickly, and the brake system was tested for performance.
Result: The brake shoe returned properly, eliminating dragging and reducing wear. The winch resumed normal operation within 1.5 hours, and the spring has operated stably for 8 months, reducing maintenance frequency and costs.

Case 2: ZJ32L Drilling Rig Hydraulic System Contamination

Equipment: ZJ32L drilling rig hydraulic system
Fault: The hydraulic system experienced frequent valve jams and pump wear, leading to reduced system performance. The original oil suction filter (non-our product) failed to filter out small impurities effectively.
Diagnosis: The original filter had low filtration precision and a small dirt-holding capacity, leading to impurity buildup in the hydraulic system, which caused valve jams and pump wear.
Solution: Replaced with our ZJ32L Oil Suction Filter NJU-250×180F, which has high filtration precision and a large dirt-holding capacity. Cleaned the hydraulic system and refilled with clean hydraulic oil.
Result: The hydraulic system resumed normal operation immediately, and valve jams and pump wear were eliminated. The filter element’s service life was extended by 60% compared to the original part, reducing maintenance frequency and costs.

Case 3: FLO-1000 Air Pump Starter Failure

Equipment: FLO-1000 air pump with original starter (non-our product)
Fault: The air pump failed to start, disrupting the supply of compressed air to the drilling rig. The original starter (non-our product) had a faulty motor and worn teeth, leading to ignition failure.
Diagnosis: The original starter was a low-quality replacement part that did not meet OEM specifications, with a weak motor and worn teeth that could not engage the engine properly.
Solution: Replaced with our FLO-1000 Air Pump Starter 24V 11T 11.2KW, which meets OEM specifications and features a durable motor and intact teeth. The starter was installed and tested for ignition performance.
Result: The air pump started immediately, restoring compressed air supply to the drilling rig. The starter has operated stably for 7 months, ensuring uninterrupted air pump operation and supporting drilling activities.
