FAQ;

5. Fault Diagnosis & Troubleshooting

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

Cause Solution
Motor rotation direction is reversed Swap 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/leaking Clean or replace the suction filter; repair leaks in the suction line.
Oil level in the tank is too low Add 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 Type Possible Cause Solution
Whistling Cavitation (air in the suction line) Check for suction line leaks; ensure oil level is sufficient; clean the suction filter.
Knocking Shaft misalignment or coupling damage Realign the pump and motor shafts; replace the damaged coupling.
Grinding Bearing wear or foreign debris in the pump Disassemble the pump; replace worn bearings; flush internal passages to remove debris.
Vibrating noise Loose mounting bolts or swashplate jamming Tighten 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?

Cause Solution
Insufficient oil flow in the cooling system Check the cooler fan/pump; clean the cooler’s heat exchanger (remove dirt buildup).
Hydraulic oil viscosity is too high Replace 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.
