Thread Content

Series: Rexroth piston pumps A10VSO series (32 series)
Specifications: 28, 45, 71, 100, 140
Operating pressure: Rated pressure: 28 MPa, Peak pressure: 35 MPa
Control methods: DG – Dual-point control, direct operation; DR – Pressure control; DRG – Pressure control with remote operation; DRF/DRS – Pressure and flow control; LA……Pressure, flow, and power control; LA…Variable; ED – Electro-hydraulic control
Features: Axial piston – Variable pump with swashplate design – Flow is proportional to drive speed and displacement – Hydrostatic loading of swing bearing – Pressure sensor-equipped port at the pump outlet – Low noise – Low pressure pulsation – High efficiency – Strong resistance to cavitation, suction pressure drop, and peak casing pressure – Universal shaft drive
Safety notes: ▶ Hazards present during and shortly after surgery: Axial piston units and especially burned solenoids. Take appropriate safety measures (for example, by wearing protective clothing). ▶The control devices of moving parts (such as valve spools) can, in some cases, become stuck in certain positions as a result of contamination (such as impure hydraulic FUID from components, wear, or residual dirt). As a result, the FOW of the hydraulic FUID and the accumulated torque in the axial piston unit can no longer respond correctly to the operator’s SPECIFICATIONS. Even the use of various filtering elements (external or internal FOW filtering) cannot eliminate errors; it can only help reduce the risk of micro-mistakes. Machine/system manufacturers must test whether remedial measures on the machine are required to drive the concerned application to a safe position (such as a safe stop), and if so, to ensure that they are carried out correctly. Points to note for project planning ▶ This A10VSO pump is designed for open-circuit operation. ▶Project planning, installation, and commissioning of axial piston units require skilled personnel. ▶Before using the axial piston unit, please read the corresponding instructions carefully and thoroughly. If necessary, these are required to come from Bosch Rexroth. ▶To finalize your design, mandatory installation drawings for the functions are required. ▶The data and instructions in this article must be followed. ▶Pressure control is a pressure backup overload that is not opposed. A separate pressure relief valve is used in hydraulic systems for implementation purposes. ▶The characteristic curve of the units (operating pressure, temperature of the FUID) depending on the operating condition of the axial piston may change. ▶Not all versions of the product are approved for use with safety functions in accordance with ISO13849; please consult the relevant responsible person at Bosch Rexroth. If you need reliable parameters such as the MTTFd value for functional safety, contact them. ▶Working line port: - The port and fastening threads are designed for the specified maximum pressure. Machine or system manufacturers must ensure that the connecting elements and lines correspond to the necessary safety factors for the specified operating conditions (pressure, FOW, hydraulic FUID, temperature). -The service and function oil ports are designed only for hydraulic pipelines.
