Understanding System Requirements

7004554
Before beginning the design process, it is essential to have a clear understanding of the specific requirements for your hydraulic system. Consider factors such as load handling capacity, operational speed, and the range of environmental conditions in which the system will operate. Knowing these requirements will inform the selection of components and system configuration.
Choosing the Right Components
Sauer Danfoss provides a wide array of hydraulic components that contribute to energy efficiency. Key components to focus on include:
Hydraulic Pumps: Opt for variable displacement hydraulic pumps, such as Sauer Danfoss’ series of axial piston pumps. These pumps adjust their output based on demand, reducing energy consumption compared to fixed displacement pumps.
Hydraulic Motors: Select high-efficiency hydraulic motors that are compatible with your chosen pumps. Sauer Danfoss offers efficient options that minimize energy losses through advanced design and materials.
Valves: Incorporate proportional and servo valves that provide precise control over flow and pressure. This allows for more efficient energy use since the system can respond dynamically to changes in demand.
Accumulators: Use hydraulic accumulators to store energy during low-demand periods and release it when needed. This helps balance the system’s pressure and flow requirements efficiently.
Filtration Systems: Ensure that you have robust hydraulic filtration systems in place to maintain fluid cleanliness. Contaminated fluid can lead to increased wear and tear, resulting in energy losses.
