小型机械液压传动系统的设计,其主要任务是;根据机械的动作要求,合理地选用各种标准元件,并有机地组合起来,形成所要求的液压系统。其中也包括需要设计的一些非标准元件如油缸等。本文主要是谈谈如何根据标准元件(泵、阀、油马达等)设计液压系统,至于元件的设计,暂不述及。液压传动系统设计的内容和步骤大体如下; Small mechanical hydraulic drive system design, its main task is; according to the requirements of the mechanical action, the rational use of a variety of standard components, and organically combined to form the required hydraulic system. Which also includes the need to design some non-standard components such as fuel tanks and so on. This article is mainly about how to design a hydraulic system based on standard components (pumps, valves, oil motors, etc.). As for the design of components, we will not talk about it. Hydraulic transmission system design content and steps are as follows;
