Maintenance & Care Recommendations

Proper maintenance of spare parts is essential to extend their service life and ensure optimal equipment performance. Below are practical, easy-to-follow tips for daily use and maintenance:

1. Regular Inspection

Inspect seals (5300200156, 5300300024), filters (TFX-400×80, 1421403), and brake components (508459, PSZ75-3-00) monthly for wear, clogging, or leakage—replace immediately if damage is found to prevent system failure. Check PDC drill bits (DM1624BGU) for cutter wear after each drilling operation, as excessive wear can reduce drilling efficiency.

2. Cleaning & Lubrication

Clean hydraulic filters (ZJ32L TFX-400×80) and lubricators (ZJ45 QYW-L40-whl) every 3 months to remove debris and prevent clogging. Lubricate moving parts (spline bushings, bearings, gears) with high-temperature lubricating oil to reduce friction and wear. Flush disc brake pipelines (A8II-650, Y/G6I-800 A2) annually to remove contaminants and maintain fluid flow.

3. Storage Guidelines

Store spare parts in a dry, clean, and temperature-controlled environment (10-25℃) to avoid rust and damage. Seals and rubber components (O-rings, airbags) should be stored away from direct sunlight and chemicals to prevent aging. Electronic components (3607010050H, 361804120590000000) should be stored in anti-static packaging to protect sensitive circuits. Explosion-proof components should be stored in a dust-free environment to maintain their safety certification.

4. Replacement Schedule

Follow these recommended replacement intervals: Filters and filter elements every 6 months or 500 operating hours; seals and gaskets every 6-12 months (or sooner if leakage is observed); brake components (508459, PSZ75-3-00) every 12-18 months (depending on usage); PDC drill bits (DM1624BGU) based on drilling footage; bearings every 24 months or during equipment overhauls. Valves and pumps should be inspected annually and replaced if signs of wear are present.
