A10VSO140DFR1/32L-PPB22U00 A10VSO140DRG/32L-PPB22U99 German original Rexroth plunger pump hydraulic oil pump
| Rexroth A10VSO hydraulic pump |
| 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? |

FAQ:
1. What is the A10VSO140 pump?
The A10VSO140 is an axial piston variable displacement pump from the Rexroth A10VSO series, designed for open-loop hydraulic circuits. It is widely used in industrial and mobile applications (e.g., excavators, construction machinery) due to its high-pressure capacity and robust performance.
2. What are the key specifications?
• Displacement: 140 cc/rev (model-specific).
• Control Types: DR, DFR, DRG, DFR1, DFLR (for flow/pressure regulation).
• Pressure Rating: High-pressure operation (exact PSI/bar values depend on configuration).
• Shaft Rotation: Typically clockwise (CW) or counterclockwise (CCW), depending on the model.
3. What are the compatible parts and components?
Common replaceable parts include:
• Cylinder block (barrel)
• Piston assembly
• Valve plate
• Swash plate
• Drive shaft
• Thrust plate.
4. How to identify the model number?
Example model: A10VSO140DFLR/31R-PPB12N00
• A10VSO140: Series and displacement.
• DFLR: Control type (e.g., DFLR for pressure limiting and load sensing).
• 31R: Porting configuration.
• PPB12N00: Additional design codes.
5. What are common applications?
