Sähköhydraulinen

Sähköhydraulinen refers to a system that combines electrical and hydraulic components to achieve a specific function. In these systems, electrical signals are used to control hydraulic actuators, which in turn perform mechanical work. This integration allows for precise control over movements, speed, and force, leveraging the strengths of both electrical and hydraulic technologies.

The basic principle involves an electrical control unit, such as a microcontroller or programmable logic controller, receiving input from sensors or user commands. This electrical signal is then processed and used to operate electrical components like solenoid valves. Solenoid valves, when energized, redirect the flow of hydraulic fluid. This fluid, under pressure, is directed to hydraulic actuators like cylinders or motors. The movement of the cylinder or the rotation of the motor generates the desired mechanical output.

Sähköhydraulinen systems are widely used in various applications due to their advantages. They offer high power density, meaning they can generate significant force or torque from relatively compact components. They also provide precise control, making them suitable for tasks requiring accuracy, such as in robotics, industrial automation, and machine tools. Furthermore, hydraulic systems are inherently robust and can operate reliably in harsh environments. Examples include excavator controls, advanced braking systems in vehicles, and sophisticated industrial machinery. The electrical control part allows for complex logic, feedback loops, and integration with other automated systems.
