Disruption in Electrohydraulics: New Technologies Lead the Way

Hydraulic systems

Hydraulic systems have been present for over 80 years, yet in the energy debate, they are frequently characterized as inefficient energy hogs. Hydraulic systems, in fact, are one of the most efficient ways to transport mechanical energy. Newer improvements, such as electrohydraulic technology, are well-suited for certain applications. OEMs are aiming for innovative hydraulic system designs that can incorporate electronics into off-highway equipment to increase efficiency and maximize effectiveness. The application of modern electronic control technologies to hydraulic systems is known as electrohydraulics.

An electric motor is used to open or close a proportional valve instead of a pilot valve or flow control valve to manage system pressure or flow. An electronic controller that takes information from the machine’s sensors controls the electric motor. Electronic controllers are replacing pilot valves and flow control valves because they provide more control over system parameters and make it easier to integrate various functions into a single controller or system. This can minimize component count, total system size, manufacturing, and installation costs while boosting diagnostic capabilities and machine performance.

A recent Fluid Power World survey asked readers what parts of hydraulics they would want to see enhanced in their present applications. The findings indicate a need for hydraulic systems to be quicker, more efficient, and cost-effective. Hydraulic system manufacturers are increasingly investigating methods to improve the intelligence of their products using electrohydraulics, which combines electric motors and controls with hydraulics.

In the realm of electrohydraulics, the last decade has been one of innovation. Engineers may now create systems that are more efficient, effective, and cost-effective thanks to new technology and breakthroughs.
