采用液控单向阀平衡回路的实验装置设计
摘要
液压基本回路是为了实现特定的功能把有关的液压元件组合起来的典型油路结构,是组成任何液压系统的基础。平衡回路的功用就是在于防止垂直或倾斜放置的液压缸和与之相连的工作部件因自重而自行下落,使执行元件的回油路上保持一定的背压值来平衡工作的稳定。本文对采用液控单向阀的平衡回路实验装置的原理进行了详细的分析,再根据液压传动相关理论进行数据计算,设计液压缸,选择合适的液压元件、液压油箱、液压站的动力装置,然后确定电机与泵的安装方式,进行管路与管接头的选择等等,最后对本次设计的实验台装置进行性能验算,包括压力损失的验算、总统效率估算和系统温升校核三个环节。同时完成设计的总装配图及部分零件图等等,最终完成整个设计。

The design of experimental device adopts the hydraulic control one-way valve balance circuit
Abstract
The hydraulic pressure basic circuit is to put the typical circuit structure of ponents bined on the realization of specific functions, is the ponent of any hydraulic system. Balance circuit function is to prevent the hydraulic cylinder vertically or obliquely placed and connected with the working parts caused by self weight drop, so that the implementation ponents of the return line to maintain a certain pressure to balance the work stability. The principle of balance circuit experiment device of the hydraulic control one-way valve are analyzed in detail, and then the related theory of data according to the calculation of hydraulic transmission, hydraulic cylinder design, selection of ponents, power device, hydraulic station hydraulic oil tank right, then determine the installation mode of motor and pump, pipeline and pipe joint selection and so on, the performance calculation of the design of the experimental device, including temperature checking, President efficiency estimation and the pressure loss of the system or check three links. At the same time plete the design of assembly drawing and parts drawing and so on, and plete the design.
