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 (420201141124090050, BKD-11-S1) and nuts (GB6170-86) every 24 working hours, tightening them promptly if loose; inspect sealing components (60*3.55 O-Ring, 5300200031 Oil Seal) for oil or fluid leaks, replacing them immediately if damage is found; check filter elements (LXZ-400*80FS, 9N3367, BF7653) for clogging, cleaning or replacing them when the pressure difference exceeds 0.3MPa; inspect friction plates (515872) and brake blocks (PSE75B-ⅱ) for wear, replacing them when the thickness is less than 5mm.

2. Regular Lubrication

Lubricate friction plates (515872), clutches (Z16160100004AA), and guide belts (FM 3020) 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: Filter elements (LXZ-400*80FS, 9N3367, BF7653, 88290006-013), seals (60*3.55 O-Ring, 5300200031), and friction components (515872, W08-07-908) every 8000-10000 working hours; bolts (420201141124090050), impellers (FH4147, EG6137), and heating rods (ZNG-A) every 15000-20000 working hours; valves (R431003722, 40LDB) and regulators (QTY-L-8-15) every 20000-25000 working hours. For components in harsh environments (e.g., drilling sites, mud treatment 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 (WX25-1 Potentiometer, SK-2Z11 CAN Node) in waterproof packaging to prevent dust and damage; handle heavy components (Z07150200007AA Cylinder Head, YBZ-30-4W Vibration Motor) with care to avoid collision and deformation; store filters and seals in sealed packaging to prevent contamination.
