Maintenance & Care Recommendations

Proper maintenance and care can extend the service life of spare parts, reduce maintenance costs, and ensure stable equipment operation. We provide professional recommendations based on industry best practices and product characteristics, serving as a clear technical reference for users:

• Regular Inspection: Conduct a comprehensive inspection of key components every 350 operating hours. For example, check the wear of the Piston Pump 1300092727 PVP2336B8RHP21 (replace if flow rate deviation exceeds ±5%), inspect the sealing performance of the LMD O-ring AS-217 Viton 381600 GE (replace if there is oil leakage), and check the Acoustic Emission Detector DISP-32 for detection accuracy (calibrate if accuracy is below 98%).

• Lubrication Maintenance: Apply appropriate lubricating oil to transmission components (such as Gear 410970, Bearing 450114250040, and Hydraulic Pump Coupling TT5140TZJSPS-300D Q17046-0) every 120 operating hours. Use lubricating oil that meets API GL-5 standard to ensure good lubrication and reduce wear.

• Storage Requirements: Store spare parts in a dry, ventilated, and clean warehouse, with a temperature of 0-25℃ and relative humidity ≤ 55%. Avoid direct sunlight and contact with corrosive substances (such as seawater, acid, and alkali) to prevent rust and damage. For electrical parts (such as Acoustic Emission Detector DISP-32) and control components, store them in sealed packaging to avoid moisture and dust.

• Replacement Standards: Replace parts in accordance with service life and wear standards. For example, the service life of the Diesel Filter BEZK183/H 12 110/2 X is 160 operating hours, and it should be replaced in time to ensure fuel filtration efficiency; the service life of the Rexroth Valve R431003982/P57081-1/6P-5S is 9500 operating hours, and regular inspection and replacement should be carried out to ensure hydraulic system performance.
