Troubleshooting Guide
Insufficient or No Oil Output
- Causes: Clogged oil filter, low oil level, air leakage, internal pump leakage, small inclination angle, motor reversal
- Solutions: Clean filter, add oil, check seals, replace worn parts, adjust variable piston, correct motor phase sequence
High Vibration and Noise
- Mechanical Causes: Misalignment, damaged coupling, loose bolts, bearing wear
- Hydraulic Causes: Restricted inlet, clogged filter, high viscosity
- Solutions: Realign components, replace damaged parts, select proper oil, ensure smooth piping
Pump Overheating
- Causes: Improper mechanical clearance, high-pressure leakage, filter blockage
- Solutions: Adjust gaps, increase cooling capacity, clean/replace filter
Maintenance Guidelines
- Maintain oil temperature at 25-60℃ with cleanliness level ≥8
- Conduct comprehensive inspections every 6 months (seals, filters, components)
- Check oil replenishment pump status after 3000 hours of operation
- Always prime pump before starting to prevent dry friction
Installation Requirements
- Pump/motor shaft concentricity <0.05mm
- Maximum suction height: 500mm
- Use original seals and wear-resistant components for replacements
Quality Assurance
Inspection Criteria
- IQC: Dimensional checks per DWG-100-01 (tolerance ±0.05mm)
- IPQC: Leakage test at 1.5x rated pressure (15-min hold)
- OQC: Noise level ≤75 dB(A) at 1500 rpm
Note: Critical defects include seal failure and pressure drop >10%
