Technical Description
Troubleshooting Guide
Insufficient or No Oil Output
Possible Causes:
Excessive resistance in oil suction pipeline (clogged oil filter, low oil tank level, or air leakage)
Internal leakage of the pump (scratches on oil distribution plate, poor sealing)
Inclination angle of the inclined plate too small
Motor reversal (incorrect phase sequence)
Solutions:
Clean oil filter, add oil to normal level, check pipeline sealing
Replace worn parts (plungers, oil distribution plates) or grind mating surfaces
Adjust variable piston to increase inclination angle
Adjust motor phase sequence
Abnormal Pressure (Too High/Too Low)
Low Pressure Solutions:
Check for pipeline leaks
Inspect overflow valve faults
Check cylinder block distribution plate leaks
High Pressure Solutions:
Adjust overflow valve
Check directional valve or return oil pipeline
Daily Maintenance
Maintain oil temperature at 25-60℃, cleanliness level ≥8
Conduct comprehensive inspection of seals, filters every 6 months
After 3000 hours operation, check oil replenishment pump status daily
Ensure pump is filled with oil before starting to avoid dry friction
Installation Requirements
Pump shaft and motor shaft concentricity <0.05mm
Suction height should not exceed 500mm
Use original seals and wear-resistant components for replacements
