Principle of action of the hydraulic system

The function of a hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely, power components, actuators, control components, auxiliary components (accessories) and hydraulic fluid. Hydraulic system can be divided into two categories: hydraulic transmission system and hydraulic control system. Hydraulic transmission system to transfer power and movement as the main function. Hydraulic control system to make the output of the hydraulic system to meet specific performance requirements (especially dynamic performance), usually referred to the hydraulic system mainly refers to the hydraulic transmission system.
