How do you make a hydraulic system energy efficient?

2 Optimize the system layout

Another step to make your hydraulic system energy efficient is to optimize the system layout and design. You should minimize the length and diameter of the pipes and hoses, as this can reduce the friction and pressure losses in the system. You should also avoid sharp bends, fittings, and joints, as these can create turbulence and resistance in the flow. You should also arrange the components in a logical and compact way, so that they are close to each other and to the load, and that they have the shortest possible flow paths. This can also reduce the heat generation and the risk of leakage in the system.

3 Use variable speed drives

A variable speed drive (VSD) is a device that can adjust the speed and torque of a hydraulic pump or motor according to the load demand. By using a VSD, you can reduce the energy consumption and the heat generation of your hydraulic system, as you can avoid running the pump or motor at full speed or pressure when it is not needed. A VSD can also improve the control and the response of your hydraulic system, as you can regulate the flow and pressure more precisely and smoothly. A VSD can also extend the life of your hydraulic system components, as it can reduce the wear and tear caused by frequent start-ups and shut-downs.

4 Implement load-sensing control

A load-sensing control is a type of hydraulic control that can adjust the flow and pressure of the system according to the load demand. By implementing a load-sensing control, you can make your hydraulic system more energy efficient, as you can avoid wasting energy by delivering more flow or pressure than needed. A load-sensing control can also improve the performance and the safety of your hydraulic system, as you can achieve faster and more accurate load movements and prevent overloading or cavitation. A load-sensing control can also reduce the noise and the emissions of your hydraulic system, as it can lower the pump speed and the system pressure.

5 Maintain the system regularly

The last step to make your hydraulic system energy efficient is to maintain the system regularly and properly. You should check and replace the filters, seals, fluids, and other components that can affect the efficiency and the reliability of your hydraulic system. You should also monitor and measure the system parameters, such as flow, pressure, temperature, and power, and compare them with the design values and the performance indicators. You should also identify and fix any problems or faults that can cause energy losses, such as leaks, clogs, misalignments, or malfunctions. By maintaining your hydraulic system regularly, you can ensure its optimal operation and prevent any unnecessary energy waste or damage.
