液压系统，也称为液压泵站、液压站、液压动力单元等。
Hydraulic system, also known as hydraulic pump station, hydraulic station, hydraulic power unit, etc.
液压系统通常都是由液压元件（动力元件、执行元件、控制元件、辅助元件）和工作介质两大部分组成。
The hydraulic system is usually composed of two parts: hydraulic components (power components, actuator components, control components, auxiliary components) and working medium.
液压系统按照电机安装方式，分为立式、卧式、旁置式液压系统。
According to the motor installation method, the hydraulic system is divided into vertical, horizontal and side-mounted hydraulic systems.
