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 brake components (DW 40C0605JG000016 Brake Pad, ZJ70/4500DZ Brake Hydraulic Pipeline PSZ 75), valves (Q41M-1.6/DN25, J13W-320P), and hydraulic lines (DQ70BS 50H0442 M30-275) every 500 operating hours for signs of wear, cracks, or leakage. Replace damaged parts promptly to avoid equipment failure, especially safety-critical components.

• Filtration System Maintenance: Replace oil suction filters (ZJ50D28 NJU-250*180F) and filter elements (4N0015) 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 motors.

• Lubrication: Apply appropriate lubricating oil to moving parts such as cardan shafts (ZJ45 SWP360A), idle chain wheels (JC068.01.04.29), and pulleys (ZJ70 102.19.10). Use lubricants that meet OEM specifications to reduce friction and wear, and avoid mixing different types of lubricants.

• 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 (BX3-60-3P+E Hanging Aviation Plug Connector, Relay 330401140007000000), store them in anti-static packaging to protect their performance.

• Professional Installation & Testing: Ensure parts are installed by trained maintenance technicians. 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 safety-critical parts like brake pads and high-pressure valves.

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: ZJ70/4500DZ Drilling Rig Brake Pipeline Leakage

Equipment: ZJ70/4500DZ drilling rig disc brake system
Fault: The brake system lost pressure, and the winch could not stop safely. The original brake hydraulic pipeline (non-our product) was leaking oil at the connections.
Diagnosis: The original pipeline was made of low-quality material with poor pressure resistance, leading to wear and leakage at the connections after long-term use in high-vibration, high-pressure environments.
Solution: Replaced with our ZJ70/4500DZ Disc Brake Hydraulic Pipeline PSZ 75, which is made of high-pressure-resistant, wear-resistant material and features reinforced connection points. The pipeline was installed quickly, and the brake system was refilled with clean hydraulic oil.
Result: The brake system pressure returned to normal within 1.5 hours, and the winch resumed safe operation. The pipeline has operated stably for 7 months without further leakage or damage.

Case 2: Boiler WNS1-1.25 Ball Valve Leakage

Equipment: Boiler WNS1-1.25
Fault: The high-temperature ball valve leaked, leading to heat loss and reduced boiler efficiency. The original valve (non-our product) could not withstand the high temperature and pressure of the boiler system.
Diagnosis: The original valve used a low-grade seal and body material that degraded under high temperature, leading to leakage and reduced performance.
Solution: Replaced with our Boiler WNS1-1.25 High Temperature Ball Valve Q41M-1.6/DN25, which features a heat-resistant body and high-quality seal designed for high-temperature, high-pressure boiler operations. The valve was installed and tested for leak-free performance.
Result: The valve stopped leaking immediately, and boiler efficiency returned to normal. The valve has operated stably for 8 months in high-temperature conditions, ensuring safe and efficient boiler operation.

Case 3: ZJ50D28 Winch Oil Pump Failure

Equipment: ZJ50D28 winch oil pump system
Fault: The winch oil pump failed to deliver oil, leading to winch inoperability. The original oil suction filter (non-our product) was severely clogged by impurities.
Diagnosis: The original filter had low filtration precision and a small dirt-holding capacity, leading to rapid blockage by oil impurities, which caused the pump to fail.
Solution: Replaced with our ZJ50D28 Oil Suction Filter NJU-250*180F, which has high filtration precision and a large dirt-holding capacity. Cleaned the oil pump and pipeline, and refilled with clean oil.
Result: The oil pump resumed normal operation immediately, and the winch was functional again. The filter’s service life was extended by 50% compared to the original part, reducing maintenance frequency and costs.
