|
| REXROTH A10VSO Variable Displacement Piston Pump 31R Series |
| Open circuit RC 92 711/09.00 |
| Specification 28... 140 |
| 31R series |
| Rated pressure 280 bar |
| Peak pressure 350 bar |
|
| Characteristics of this type of pump: |
| - Axial piston variable displacement pump with inclined disc
structure for hydraulic open circuit |
| The flow rate is proportional to the driving speed and
displacement, and can achieve stepless variable by adjusting the
tilt angle of the inclined plate |
| - ISO standard installation flange |
| - Flange connection conforms to SAE metric system |
| - There are two shell oil drain holes |
| - Excellent inhalation performance |
| - Allow continuous operation pressure up to 280 bar |
| - Low noise |
| - Long lifespan |
| - The drive shaft can withstand axial and radial loads |
| - High power/weight ratio |
| Multiple control forms with a wide range |
| - Short response time control |
| - Adopting a through axis structure, it can be used for multi
circuit systems |
|
| Model selection reference explanation: |
| Example model: A10VSO18DFR1/31R-PPA12N00 |
| A10VS → inclined disc variable displacement pump, this series is
used for industrial drive, with a nominal pressure of 28MPa and a
maximum pressure of 35MPa; |
| O → Operation mode, this series is used for open circuit systems; |
| 18 → Displacement specification: This model has a displacement of
18m3 (there are also common specifications such as 10, 28, 45, 71,
100, 140, etc.) |
| DFR1 → control mechanism, (DG represents two position control
direct drive; DR (G) table; Remote control of pressure indication
control; DFR (1) pressure/flow control; There is no small hole in
the X oil circuit with one finger; DFLR pressure/flow/power
control; FHD flow control, related to pilot pressure with pressure
control; FE1 * * Flow control; DFE 1 * * Pressure/Flow Control; ED
hydraulic pressure control); |
| 31 → Product Series |
| R → Rotation direction (R clockwise, L counterclockwise) |
| P → Sealing (P refers to NBR (nitrile rubber, compliant with DIN
ISO 1629) with FKM shaft seal, V refers to FKM (Buddha rubber,
compliant with DIN ISO 1629)) |
| P → Shaft end (P refers to the key straight shaft DIN 6885, S
refers to the spline shaft SAE, R refers to the spline shaft SAE
(higher shaft drive torque)); |
| A → Install flange holes (A refers to ISO 2 holes, B refers to ISO
4 holes); |
| 12 → Connect the working oil port, with {pressure oil port B and
suction port S} in the opposite direction, and fix the SAE oil port
with metric screws; |
| N00 → through axis, (N00 has no through axis drive; There are axial
pumps with axial drive, gear pumps, radial piston pumps KB2, K51,
∝, K01, etc.) |
