1. Hydraulic System: Core Power Maintenance
Fluid Condition Monitoring
Regularly inspect hydraulic fluid levels and cleanliness. Replace contaminated fluid immediately to prevent valve blockage.
Monitor oil temperature closely. Abnormal overheating (above 80°C) indicates potential radiator blockage or fluid degradation, requiring immediate troubleshooting.
Critical Component Diagnosis
Pressure anomalies in the main pump or hydraulic valves require inspection of seals for wear or internal component jamming.
Slow cylinder movement may signal internal leaks; check seal aging and replace as needed.
Contamination Control Measures
Install multi-stage filtration (suction filter: 30μm, return filter: 10μm) and replace elements every 500 hours to eliminate metal debris.
Purge air from the system during fluid replacement to prevent cavitation damage.
2. Electronic Control System: Intelligent Troubleshooting
Diagnostic Code Interpretation
Retrieve error codes via the dashboard display (e.g., "E03" indicates hydraulic pump overload) and cross-reference with technical manuals.
Circuit Verification
Measure battery voltage (24V ±0.5V) and inspect CAN bus terminal resistance (60Ω ±5%) to rule out wiring faults.
Sensor Calibration
Perform zero-point calibration for temperature and pressure sensors to ensure data accuracy.
3. Mechanical Components: Daily Maintenance Essentials
Undercarriage Maintenance
Monthly inspection of track tension (15-20mm sag) and drive sprocket bolts tightened diagonally to 250N·m.
Braking System Care
Check brake pad thickness (replace if <5mm) and replace brake fluid every 2000 hours to prevent hydraulic fade.
Environmental Adaptation
Install protective grilles (≤5mm mesh) in mining areas to shield critical components from debris.
Pre-heat hydraulic systems in cold environments to avoid oil film rupture.
