A complete hydraulic system consists of five parts, namely power components, actuating components, control components, auxiliary components and hydraulic oil. Hydraulic equipment is a combination of all parts. Hydraulic equipment has large transmission force, easy transmission and configuration, and is widely used in industrial and civil industries. The function of the hydraulic cylinder and hydraulic motor, the actuating elements of the hydraulic system, is to convert the pressure energy of the liquid into mechanical energy to obtain the required linear reciprocating motion or rotary motion. You can freely modify components to achieve the desired work according to the desired action.
