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 bolts (420201041116035050, 5402650320, 7415648) and connectors (ZJ45 JSZ-35MPa, ZJ70 H4 series) every 24 working hours, tightening them promptly if loose; inspect sealing components (P1700312AA, G04050400010AA) for oil or air leaks, replacing them immediately if damage is found; check filter cores (TZ400*30, RFB-250×10Y) for clogging, cleaning or replacing them when the pressure difference exceeds 0.3MPa.

2. Regular Lubrication

Lubricate bearings (Apr-23 Locknut Bearing), shafts (646490557, DAM073M), and connecting rods (1W7524/9Y9497) every 600 working hours using industrial-grade lubricating oil (e.g., 68# anti-wear hydraulic oil), 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易损 parts according to service life: Friction plates (LT500/250), brake blocks (PSE75-ⅲ), and O-rings (P1700312AA) every 8000-10000 working hours; filter cores (TZ400*30, RFB-250×10Y) every 1200-1800 working hours; impellers (GGH10137) and shafts (646490557) every 15000-20000 working hours. For components in harsh environments (e.g., drilling sites, mining areas), 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 (MWD 406099 transition outer cylinder, AH100101052200 lower stem guide) in waterproof packaging to prevent dust and damage; handle heavy components (DAM073M gravel pump shaft, P1500016AA flange) with care to avoid collision and deformation.
