| 1. What are the possible causes and solutions for insufficient or no oil output from the hydraulic pump? |
| • Reason: |
| Excessive resistance in the oil suction pipeline (such as clogged oil filter, low oil tank level, or air leakage in the inlet pipe). |
| Internal leakage of the pump (scratches on the oil distribution plate, poor sealing, sand holes, etc.). |
| The inclination angle of the inclined plate is too small and the displacement is insufficient. |
| Motor reversal (requires adjustment of phase sequence). |
| • Solution: |
| Clean the oil filter, add oil to the normal liquid level, and check the sealing of the pipeline. |
| Replace worn parts (such as plungers, oil distribution plates) or grind mating surfaces. |
| Adjust the variable piston to increase the inclination angle of the inclined plate. |
| 2. How to adjust if there is still traffic output at the median level? |
| Reason: Deviation, looseness, or wear of the control mechanism (such as wear of the inclined plate ear shaft). |
| Solution: Reset the controller, tighten or replace damaged parts, and check the angle holding force. |
| How to troubleshoot the high vibration and noise during pump operation? |
| • Mechanical reasons: |
| The pump and motor shaft are not concentric, the coupling is damaged, or the bolts are loose. |
| Wear of bearings or variable head bearings (dry friction or impurities in the oil during start-up). |
| • Hydraulic reasons: |
| The oil inlet pipe is too thin, the oil filter is clogged, or the oil viscosity is too high. |
| • Solution: |
| Reinstall and replace worn parts. |
| Select appropriate oil to ensure smooth fuel tank design and piping. |
| What are the causes and solutions for overheating of the pump body? |
| • Reason: |
| Mechanical friction (such as improper clearance between moving parts) or liquid friction (high-pressure oil leakage converted into thermal energy). |
| Filter blockage leads to excessive back pressure in the return oil. |
| • Solution: |
| Adjust the gap and increase the capacity of the cooler or fuel tank. |
| Clean or replace the filter. |
| How to solve the problem of oil leakage? |
| • Common oil leakage points: |
| Damaged spindle oil seal, internal leakage (high oil seal pressure), loose external pipeline or aging sealing gasket. |
| • Solution: |
| Replace the oil seal or defective shaft, check the size of the oil drain pipe, and tighten the joint. |
| What are the key points of daily maintenance? |
| • Oil management: |
| Maintain oil temperature at 25-60 ℃, cleanliness level ≥ 8, and regularly test oil quality. |
| • Regular inspection: |
| Conduct a comprehensive inspection of seals, filters, and mechanical components every 6 months. |
| After running for 3000 hours, it is necessary to check the status of the oil replenishment pump daily. |
| Before starting: Ensure that the pump is filled with oil to avoid dry friction. |
| How to adjust abnormal pressure (too high/too low)? |
| • Low pressure: Check for pipeline leaks, overflow valve faults, or cylinder block distribution plate leaks. |
| Excessive pressure: Adjust the overflow valve, check the directional valve or return oil pipeline. |
| ------ |
| precautions |
| Installation requirements: The concentricity between the pump shaft and the motor shaft should be less than 0.05mm, and the suction height should not exceed 500mm. |
| • Spare parts replacement: It is recommended to use original seals and wear-resistant components to ensure compatibility. |

FAQ:
What are the key technical specifications?
• Displacement (Vg max): 71 cm³/rev
• Nominal Pressure (p nom): 280 bar
• Maximum Pressure (p max): 350 bar
• Speed Range: Up to 2,200 rpm (at Vg max)
• Flow Rate (at nominal speed): 156 L/min
• Weight: ~33 kg (standard model)
• Control Options: Pressure cutoff (DR type), load sensing, or proportional control variants.
3. How does the "pressure cutoff" function work?
The A10VSO71DR variant features a pressure cutoff (DR control) mechanism. When system pressure reaches the preset cutoff value, the pump reduces its displacement to maintain constant pressure, minimizing energy consumption. Contrary to some misconceptions, the swashplate does not always return to the minimum angle; it adjusts dynamically based on flow demand while sustaining pressure.
4. What are common applications?
This pump is ideal for:
• Hydraulic presses and injection molding machines.
• Construction machinery (e.g., excavators, cranes).
• Marine and offshore systems.
• Industrial hydraulic power units.
5. How to troubleshoot performance issues?
• Low Flow/Output: Check for clogged filters, worn seals, or incorrect control settings.
• Overheating: Verify fluid viscosity, cooling system, or excessive pressure settings.
• Noise/Vibration: Inspect for cavitation, air ingress, or misalignment.
6. Where can I find repair services?
Certified repair centers (e.g., Shenzhen Ou Hang Fluid Power) offer testing and refurbishment for A10VSO71 pumps, including seal replacements, swashplate repairs, and performance validation.
7. Are there compatible accessories or valves?
Yes, Rexroth provides matched components like:
• Proportional valves (e.g., 4WE series).
