　　The function of hydraulic system is to increase the acting force by changing the pressure. A complete hydraulic system consists of five parts, namely, power component, executive component, control component, auxiliary component (accessories) and hydraulic oil. Hydraulic system can be divided into two categories: hydraulic transmission system and hydraulic control system. The main function of hydraulic transmission system is to transmit power and motion. The hydraulic control system needs to make the output of the hydraulic system meet the specific performance requirements. Usually, the hydraulic system mainly refers to the hydraulic transmission system.
