The hydraulic cylinder is a common actuator in the hydraulic system, and its speed range refers to the moving speed range of the cylinder under different working pressures. The size of the speed range directly affects the working flexibility and efficiency of the cylinder.

Hydraulic cylinder as an important actuator in hydraulic system, its basic structure is mainly composed of cylinder, cylinder head, piston, piston rod, sealing device and guide parts.

understand the load requirements: first of all, it should be clear that the device needs to withstand the type and size of the load. The load can be static (e.g., supporting the weight of an object) or dynamic (e.g., moving or lifting an object). Determine the weight, direction, speed and other parameters of the load.
