Maintenance & Care Suggestions
Proper maintenance and care can significantly extend the service life of our replacement parts and ensure the stable operation of your equipment. Based on years of industrial field experience, we provide practical, easy-to-follow suggestions that help users reduce maintenance costs and avoid equipment failure:
• Regular Inspection: Check sealing parts (e.g., WECO Union seal rings, ZQ162 O-rings) every 380 working hours for wear, cracks, or deformation; inspect filters, motors, and pressure gauges for abnormal operation or damage. Replace worn parts promptly to avoid further equipment damage.
• Lubrication Maintenance: Apply professional lubricants (recommended: ISO VG 68 hydraulic oil for bearings, high-temperature grease for gears) every 220 working hours to reduce friction and wear. Avoid mixing different types of lubricants, as this can damage components and reduce service life.
• Filter Maintenance: Clean or replace air, oil, and servo filters (e.g., 123-6856, 417-6207) every 750 working hours to ensure filtration efficiency. Clogged filters can cause fluid circulation problems, engine overheating, and servo system failure.
• Storage Requirements: Store unused parts in a dry, ventilated, and dust-free warehouse. Keep seals and O-rings in a low-temperature environment (5℃-25℃) to prevent aging; avoid storing metal parts (gears, pinions) in humid areas to prevent rust and corrosion. For electrical parts, store in anti-static packaging to avoid damage.
• Installation & Operation Notes: When installing parts (e.g., ZJ-20 pressure gauge, YB3-160M-4 motor), ensure the interface is clean and free of impurities. Torque bolts according to standard specifications (recommended: 75-95 N·m for flange bolts) to avoid leakage or loosening. For electrical parts, ensure correct wiring and grounding to prevent short circuits or explosion hazards.

On-Site Fault Maintenance Cases
Below are 3 real, short on-site fault maintenance cases—using our replacement parts—to help you quickly identify and solve common equipment problems, serving as a practical technical reference for your maintenance team:
Case 1: ZJ-20 Drilling Rig Hydraulic Pressure Gauge Failure
Fault Phenomenon: A drilling company’s ZJ-20 drilling rig displayed inaccurate hydraulic pressure readings, leading to frequent false alarms and equipment shutdowns. Inspection found that the original pressure gauge (800902-01-0330) was faulty and could not provide reliable data.
Solution: Replace the faulty gauge with our Pressure Gauge 800902-01-0330 (tailored for ZJ-20 hydraulic system). The new gauge offers accurate readings (±1.5% accuracy) and strong anti-vibration performance. After replacement, the pressure readings were restored to normal, false alarms stopped, and the drilling rig operated continuously for over 1400 working hours without issues.
Case 2: ZQ162 Hydraulic Equipment Pinion Wear
Fault Phenomenon: A mining company’s ZQ162 hydraulic equipment experienced abnormal noise and reduced power transmission. Inspection found that the original pinion (17.03-10 ZQ16203025) was severely worn, leading to uneven power distribution and increased friction.
Solution: Replace the worn pinion with our 17.03-10 ZQ16203025 pinion (specifically for ZQ162). The new pinion is made of high-strength alloy steel with precision tooth machining. After replacement, the abnormal noise disappeared, power transmission was restored, and the pinion has maintained good wear resistance for over 1200 working hours.
Case 3: TWS-600S Pump Cooling Radiator Failure
Fault Phenomenon: An oilfield’s TWS-600S pump experienced overheating, leading to frequent shutdowns. Inspection found that the original cooling radiator (665.022 HPS GmbH) was clogged and had reduced heat dissipation efficiency.
Solution: Replace the clogged radiator with our Cooling radiator 665.022 HPS GmbH (for TWS-600S, HT-400 pump). The new radiator has an optimized fin design for efficient heat dissipation. After replacement, the pump’s operating temperature returned to normal, shutdowns stopped, and the radiator operated reliably for over 1600 working hours.
