Maintenance & Care Suggestions

Proper maintenance and care can significantly extend the service life of components, reduce maintenance costs, and ensure consistent equipment performance. Below are practical, targeted suggestions:

1. Daily Inspection

Check the tightness of nuts (T70208D, P1200004AA) and bolts (ZJ70 SC-16) every 24 working hours, tightening them promptly if loose; inspect sealing components (25014-04M-B Shaft Packing) for oil or water leaks, replacing them immediately if damage is found; check filter elements (29510918, 3018042) for clogging, cleaning or replacing them when the pressure difference exceeds 0.3MPa.

2. Regular Lubrication

Lubricate winch drive shafts (106.11.312.00), bearing box connection plates (Z030102000002AA), and clutches (ATD324H) every 600 working hours using industrial-grade lubricating oil or grease (e.g., 68# anti-wear hydraulic oil, lithium-based grease), ensuring lubrication coverage of 100% of moving parts; avoid mixing different types of lubricants to prevent reduced lubrication efficiency and component damage.

3. Periodic Replacement

Replace wearing parts according to service life: Disc brake blocks (PZ-40), filter elements (29510918, 3827643), and shaft packing (25014-04M-B) every 8000-10000 working hours; volute liners (F8110) and winch drive shafts (106.11.312.00) every 15000-20000 working hours; batteries (HKCX21-4.8V) and solenoid valves (4WE6C6X/EG24NEXZ2/BO8) every 20000-25000 working hours. For components in harsh environments (e.g., drilling sites, boiler rooms), shorten the replacement cycle by 30%.

4. Storage & Handling

Store unused components in a dry, ventilated warehouse with a temperature of 0℃-25℃ and relative humidity ≤60%, avoiding moisture, corrosion, and direct sunlight; seal precision components (HKCX21-4.8V Battery Cartridge, OWN 220-24V Inverter Driver Board) in waterproof packaging to prevent dust and damage; handle heavy components (F8110 Volute Liner, 4N7657 Water Pump) with care to avoid collision and deformation.
