OverviewBosch Rexroth expands its eOC platform by adding the new A10VO Series 60 medium pressure axial piston pump
The electronic closed loop control of hydraulic pumps in open circuits with Rexroth eOC – electronic Open Circuit – opens up new possibilities for the implement hydraulics of mobile machines. With the new A10VO/60 axial piston pump, Bosch Rexroth is now expanding its range of eOC-capable pumps to cover medium pressure applications with nominal pressures of up to 280 bar (320 bar maximum pressure).
Bosch Rexroth's eOC architecture shifts the complexity of a hydromechanical pump control to the BODAS eOC Pump Control software. In order to allow this interaction, the axial piston pump is equipped with sensors for the swivel angle and pressure. This means that the control is no longer limited to mechanically fixed control variables such as torque, pressure or flow rate as it was in the past. Instead, the control strategy can switch to the optimum control variable depending on the work situation. This makes machines even more versatile and flexible. At the same time, it increases productivity and reduces energy consumption.
Improvements in pulsation, size and efficiency
The A10VO/60 is the first axial piston variable pump from Bosch Rexroth that can be equipped with an integrated pre-compression volume as standard. This option reduces pressure pulsation by up to 50 percent and thus the noise level in the operator's cab. This improvement in operating comfort can be achieved without additional, cost-intensive noise reduction measures such as engine compartment insulation, system damping or cabin insulation.
Bosch Rexroth has increased the power density of the new unit by up to 49 percent. An increase in pressure to 280 bar combined with an optimized pump design results in an installation length that is up to 10 percent shorter. The required installation space is therefore significantly less than with other comparable medium-pressure pumps.
The reworked rotary group allows very high efficiency levels in both the partial and full load range. Bosch Rexroth has completely re-engineered the proven A10 rotary groups and increased their efficiency for this purpose. This provides more hydraulic power while maintaining diesel engine performance and reducing the operating costs.
Cost savings thanks to reduced pump variance and servicing
With its reduced variance, the eOC version of the new pump offers further opportunities for cost savings because the otherwise different controller types and mechanical settings are transferred to the software. The reduced pump variance allows OEMs to reduce their stock levels and means less work when it comes to managing spare parts and aftermarket components. If servicing is required or feature updates are available, the software can be managed via the BODAS Service interface.
In addition to the eOC version, Bosch Rexroth now offers the A10VO Series 60 in a version with classic pressure-flow control (DRS).
