FAQ;

5. Fault Diagnosis & Troubleshooting

Q1: The A10VSO pump has no output flow. What are the possible causes and solutions?

CauseSolution
Motor rotation direction is reversedSwap two phases of the motor power supply to correct rotation direction.
Swashplate angle is 0° (no displacement)For DR control: Adjust the handwheel/lever to increase the swashplate angle. For EP control: Check if the electrical signal (0-10V/4-20mA) is normal.
Suction line is blocked/leakingClean or replace the suction filter; repair leaks in the suction line.
Oil level in the tank is too lowAdd hydraulic oil to the recommended level (between the tank’s upper/lower marks).
Internal wear (e.g., piston/cylinder block)Overhaul the pump; replace worn parts (pistons, cylinder block, valve plate).

Q2: The pump makes abnormal noise (e.g., whistling, knocking). How to fix it?

Noise TypePossible CauseSolution
WhistlingCavitation (air in the suction line)Check for suction line leaks; ensure oil level is sufficient; clean the suction filter.
KnockingShaft misalignment or coupling damageRealign the pump and motor shafts; replace the damaged coupling.
GrindingBearing wear or foreign debris in the pumpDisassemble the pump; replace worn bearings; flush internal passages to remove debris.
Vibrating noiseLoose mounting bolts or swashplate jammingTighten mounting bolts to the specified torque; inspect the swashplate for jamming (clean or replace if needed).

Q3: The pump’s oil temperature is abnormally high (above 80°C). What should I do?

CauseSolution
Insufficient oil flow in the cooling systemCheck the cooler fan/pump; clean the cooler’s heat exchanger (remove dirt buildup).
Hydraulic oil viscosity is too highReplace with oil of the correct viscosity (15–40 mm²/s at 40°C).
Internal leakage (e.g., worn valve plate)Overhaul the pump; replace the valve plate and piston seals.
System pressure is too high (overloaded)Reduce the system load; check if the relief valve is stuck open.
