| 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:
1. What is the A10VSO71 series?
The A10VSO71 is a variable displacement axial piston pump with a swashplate design, designed for hydrostatic transmission in open circuits. It offers stepless flow regulation by adjusting the swashplate angle and is widely used in high-power hydraulic systems for industrial and mobile applications, such as construction machinery, metallurgy, and marine equipment.
2. What are the key features of the A10VSO71 pump?
• Pressure Range: Nominal pressure of 280 bar, peak pressure of 350 bar.
• Flow Control: Flow is proportional to drive speed and displacement, adjustable via swashplate angle.
Efficiency: Energy saving modes (e.g. pressure/low/power control) reduce energy consumption by 30% compared to fixed pumps
Durability: Fluorocarbon (FKM) shaft seals, fluid hydrostatic bearing technology, and low noise design
Versatility: Supports through shaft drive for additional pump installation
3. What control options are available?
The series offers multiple control modes:
• DR/DRG: Pressure control (direct or remote).
DFR: Pressure and Flow Composite Control
DFLR: Integrated Control of Pressure, Flow, and Power
• ED/EP: Electrohydraulic proportional control.
4. How to install the pump correctly?
• Orientation: Prefer horizontal shaft mounting; Vertical installation requires rough oil priming and air blending
Drain Lines: The shell drain ports (L1/L2) must be separately led to the fuel tank, with a back pressure of ≤ 0.5 bar
Success Pressure: Maintain ≥ 0.8 bar absolute at the inlet (≥ 0.5 bar during cold start)
Piping: Use SAE standard flange ports and vibration solubilizing connectors
5. What are common faults and their solutions?
Low/No Flow: Check for clogged suction pipe, leaks, or low tilt angle of the inclined plate
Pressure Fluctuations: Inspect to control piston wear or foreign objects entering the variable mechanism
Overheating: Verify oil cleanliness (NAS ≤ 9) and cooling system
Leakage: Replace damaged shaft seal or check drain pipe design
Noise: Ensure proper oil suction pressure and coupling alignment
6. Maintenance recommendations?
Oil Quality: Use ISO VG 46 anti-wear hydraulic oil and regularly test for contamination
Seals: Inspect shaft seals every 2000 hours to shorten the cycle in high temperature environments
Long Storage: Drain oil and add rust inhibitor
