Functional Characteristics
The Rexroth A10VSO18 pump features a swashplate design, allowing for variable displacement. Its flow rate is proportional to the drive speed and the swashplate angle, providing precise control in hydraulic systems.
Swashplate Design and Hydrostatic Transmissions
The A10VSO18 pump utilizes an axial piston rotary group with a swashplate design, crucial for hydrostatic transmissions in open circuits. This design enables the pump’s variable displacement capability, allowing for precise control of fluid flow. The angle of the swashplate dictates the stroke of the pistons, directly influencing the pump’s output volume.
This variable displacement feature makes the A10VSO18 suitable for applications requiring adjustable flow rates, enhancing the efficiency and responsiveness of hydraulic systems. The swashplate mechanism ensures smooth and reliable operation, contributing to the pump’s overall performance and longevity. Furthermore, the design is optimized for use with HLP mineral oil, ensuring compatibility and optimal lubrication.
Flow Rate Proportionality
The A10VSO18 pump exhibits flow rate proportionality, meaning the output flow is directly proportional to both the drive speed and the pump’s displacement. This characteristic is fundamental to its application in open-loop hydrostatic transmissions. By adjusting the swashplate angle, the pump’s displacement can be varied, resulting in a corresponding change in the flow rate.
This proportionality allows for precise control of hydraulic actuators and motors, enabling accurate and predictable system behavior. The pump’s ability to deliver flow proportional to drive speed also contributes to energy efficiency, as the pump only delivers the required flow, minimizing wasted energy. This makes the A10VSO18 well-suited for applications requiring variable flow control and efficient operation.
