The Rexroth A4VSO series hydraulic pumps are axial – piston variable displacement pumps. They are renowned for their high – performance capabilities and are widely used in various industrial and mobile hydraulic applications.
2. Displacement and Adjustment
Displacement Range: The pumps in the A4VSO series offer a variable displacement range. The displacement can typically vary from a minimum value to a maximum value. For example, the displacement might range from around 40 cm³/rev to 1000 cm³/rev, depending on the specific model. This variable displacement characteristic allows for precise control of the flow rate output according to the requirements of the hydraulic system.
Displacement Adjustment Mechanism: These pumps are equipped with a reliable displacement adjustment mechanism. It can be adjusted either manually, through a mechanical linkage, or electronically, using appropriate control systems. The adjustment allows the pump to adapt to different operating conditions such as varying load demands and speed requirements. The adjustment range and sensitivity are designed to provide accurate and smooth control of the pump's output flow.
3. Pressure Specifications
Maximum Operating Pressure: The A4VSO pumps are designed to handle high – pressure applications. The maximum operating pressure can reach up to 350 Bar (in some cases, even higher depending on the specific configuration and application requirements). This high – pressure capability enables the pumps to be used in systems that require a significant amount of force to be generated, such as in heavy – duty hydraulic presses or large – scale construction machinery.
Peak Pressure Resistance: They also have the ability to withstand short – term peak pressures. The peak pressure resistance is an important safety factor as it protects the pump from damage during sudden pressure surges. The pump's design and internal components are engineered to handle these peak pressures without significant degradation of performance or premature failure.
