Maintenance & Care Recommendations

Proper maintenance of spare parts is essential to extend their service life, ensure optimal equipment performance, and maintain safety compliance. Below are practical, easy-to-follow tips for daily use and maintenance, tailored to the unique needs of industrial drilling and control equipment:

1. Regular Inspection

Inspect seals (F14010102, 1425867), filters (9M2341, C08964), and brake components (508725, W30-07-906) monthly for wear, clogging, or leakage—replace immediately if damage is found to prevent system failure. Check PLCs (FX1S-14MR) and flameproof electrical components (EXX) for signs of damage or loose connections, as these can compromise safety in explosive environments. Inspect inclinometer probes (EMS1-01-2) and displays (SXW300) regularly to ensure accurate data transmission. Examine friction discs and clutch components for wear, as excessive wear can reduce braking and transmission performance.

2. Cleaning & Lubrication

Clean diesel primary filters (9M2341) and portable oil filters (C08964) every 3 months to remove debris and prevent clogging. Lubricate moving parts (bearings, chainrings, planet carrier bushings) with high-temperature lubricating oil to reduce friction and wear—pay special attention to ZJ50 W489 and QYW-L15-S1 lubricators to ensure consistent lubrication. Flush hydraulic lines and cylinders (DQ70BS) annually to remove contaminants and maintain fluid flow. Clean flameproof electrical components (EXX) regularly to remove dust, ensuring they maintain their防爆 integrity.

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 (F14010102, 1425867) should be stored away from direct sunlight and chemicals to prevent aging. Electronic components (FX1S-14MR, EXX control box) should be stored in anti-static packaging to protect sensitive circuits. Flameproof components should be stored in a dust-free environment to maintain their IECEx certification and防爆 performance. Piston rings and metal components should be coated with anti-rust oil during storage to prevent corrosion.

4. Replacement Schedule

Follow these recommended replacement intervals to ensure optimal performance and safety: 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 (508725, W30-07-906) every 12-18 months (depending on usage); bearings every 24 months or during equipment overhauls; PLCs (FX1S-14MR) and electrical components every 5 years or if performance issues arise. Piston rings and clutch friction plates should be replaced when wear exceeds OEM specifications to prevent engine or transmission damage.
