Description

Technical Field

[0002] The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power elements, actuators, control elements, auxiliary elements (accessories) and hydraulic oil. The hydraulic system can be divided into two categories: hydraulic transmission systems and hydraulic control systems. During the application of the current pipeline connection mechanism, the hydraulic pipes can be fixedly connected to facilitate the subsequent use of the hydraulic system by subsequent staff.
