Comparison of Electro-Hydraulic Automation to Conventional Electric

Type of fluid, force and pressure requirements, valve response, and other factors will affect system operation. For instance, seal compatibility must be considered with fluid type due to the temperature range of the operation and its subsequent viscosity effects. Additionally, lower lifecycle costs and higher output can be achieved with an understanding of the differences between electro-hydraulic power and traditional electromechanical devices. Precise control and smooth motion of large force applications call for fluid power, so the proper selection and sizing of hydraulic system components can lead to distinct advantages over traditional electric applications.
Electro-hydraulic Versus Electric Motors
Electro-hydraulic controls are capable of moving and lifting heavy loads at slow speeds without the braking or gearing required in electric motors. They also produce less heat and consume less space than electric motors, in many cases. Concerning sizing, electro-hydraulics are sized by their average loads, whereas electrics must be sized by their maximum loads. For these reasons, electro-hydraulic pumps are of benefit with varying loads and directions, while the electric version make more sense in non-varying load situations with continuous motion, such as applications involving conveyor belts.
Electro-hydraulic controls may be located remotely, allowing weight and noise to be non-issues in applications which may concern them. The non-hydraulic motors, on the other hand, are typically located directly on the motion axis or in close proximity. The controls also have the advantage of holding constant pressure without the application of additional energy. Driving electric motors, in comparison, to apply constant torque can result in overheating. As in most things mechanical, understanding system requirements and limitations can be the key to unlocking many inherent benefits.
