An electro-hydraulic integrated system is a system that combines electrical control with hydraulic transmission, typically including components such as hydraulic pumps, valves, cylinders, motors, and control units. This system is widely used in various industrial sectors like metallurgy, shipping, construction machinery, light industry equipment, and municipal engineering, providing power and control.

Design and application of electro-hydraulic integrated systems can significantly enhance the automation level and efficiency of industrial production, while also providing more precise control capabilities. The design of these systems usually requires consideration of various factors such as specific application requirements, load characteristics, and working environment to ensure system reliability and performance.
