液压系统与液压系统机构(中文3000字,英文1900字)
一、液压系统的组成及其作用
一个完整的液压系统由五个部分组成，即动力元件、执行元件、控制元件、辅助元件（附件）和液压油。动力元件的作用是将原动机的机械能转换成液体的压力能，指液压系统中的油泵，它向整个液压系统提供动力。液压泵的结构形式一般有 齿轮泵、叶片泵和柱塞泵。

Hydraulic system and hydraulic system of institutions
First，Hydraulic system and hydraulic system of institutions
Hydraulic system and its role A complete hydraulic system consists of five parts, namely, dynamic components, the implementation of components, control components, auxiliary components (attachment) and the hydraulic oil. The role of dynamic components are the original motivation of mechanical energy into fluid pressure energy, refers to the hydraulic system of pumps, it is to the entire hydraulic system power. The structure of the general form of the hydraulic pump has Gear pumps, vane pumps and piston pumps. [来源：http://www.doc163.com]
