Features and safety instructions for Rexroth piston pumps A10VSO 31 series

Thread Content

Series: Rexroth A10VSO series variable piston pumps (31 series)
Specifications: 28, 45, 71, 100, 140
Operating pressure: Rated pressure: 28 MPa, Peak pressure: 35 MPa
Control methods: DG – Two-point direct control; DR – Pressure control; DRG – Remote pressure control; DFR, DFR1 – Pressure and flow control; DFLR – Pressure, flow, and power control; ED – Electro-hydraulic control
Features: Axial piston variable pump with swashplate design, used for hydrostatic transmission in open-loop systems. - Flow rate is proportional to drive speed and displacement. - By adjusting the angle of the swash plate, a stepless variation in flow rate can be achieved. - 2 oil drain ports on the housing. - Excellent oil absorption properties. - Low noise level. - Long service life. - Axial and radial load capacity of the drive shaft. - Ideal power-to-weight ratio. - Multiple control ranges. - Short control time. - This pump features a through-shaft drive and can accommodate gear pumps or axial piston pumps of the same or lower specifications, meaning 100% through-shaft drive. Safety instructions: - The A10VSO pump is designed for open circuits. - The project planning, assembly, and commissioning of axial piston units must be carried out by qualified personnel. - Before using the axial piston unit, please read the corresponding instruction manual thoroughly. - If necessary, request these manuals from Bosch Rexroth. - During operation and shortly after, the axial piston unit (especially the electromagnet) may pose a risk of burns. Appropriate safety measures should be taken (such as wearing protective clothing). - Depending on the different operating conditions of the axial piston unit (operating pressure, oil temperature), its characteristics may change. - Working line oil port: · The oil port and fixing thread are designed for the maximum specified pressure. Machine or system manufacturers must ensure that the safety factors of the connecting components and pipelines meet the specified operating conditions (pressure, flow rate, hydraulic oil, temperature). · The working line oil ports and functional oil ports are designed solely for hydraulic lines. - Pressure cut-off and pressure control do not provide overpressure protection. A separate relief valve is provided in the hydraulic system. - The data and instructions contained here must be followed. - This product has not been certified as meeting the requirements of the general machine safety concept specified in DIN EN ISO 13849. - Use the following tightening torques: · Joints: For the tightening torque of the joints used, please refer to the manufacturer’s instructions. · Mounting bolts: For mounting bolts that comply with the ISO metric thread standard DIN 13 and the thread standard ASME B1.1, we recommend checking the tightening torque separately in accordance with VDI 2230. · Threaded hole of the axial plunger unit: The maximum allowable tightening torque MG max applies to the threaded hole; this value must not be exceeded. · Locking screw: For the metal locking screw provided together with the axial plunger unit, a tightening torque of MV must be applied.
