FAQ: Fault Diagnosis & Troubleshooting
1: 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). |
2: 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). |
3: 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. |
