摘要

液压泵和马达作为液压系统的动力元件和执行元件，是整个液压系统的

心脏，它们的性能直接影响着整个液压系统的性能。因此液压泵、马达性能的精确测试有着非常重要的意义。液压泵和马达的性能测试是辨别产品优劣、改进结构设计、提高工艺水平、保证系统性能和促进产品升级的重要手段。

本次设计就是通过测定液压泵液压泵、液压马达在给定外界情况下的排量、流量、容积效率等，检验液压泵和液压马达的是否合格。

设计了液压泵与液压马达实验台液压系统，并对有关参数进行了计算，绘制了液压泵与液压马达实验系统原理图、泵站装配图、油箱的部件图、阀块零件图一系列相关立体图与二维图纸，为液压泵与液压马达实验台液压系统的设计奠定了理论基础。

Abstract

As the power components and the actuator components of hydraulic system ,the hydraulic pump and the motor are the heart of the entire hydraulic system, of which the performance directly affects the entire hydraulic system`s. Therefore, there is very important significance to test the performance of hydraulic pumps and motors accurately. The performance test is an important means of identifying product strengths and weaknesses, improving structural design and technological level, ensuring system performance and promoting product upgrading.

The design involved in this paper mainly discusses how to test hydraulic the eligibility of pumps and hydraulic motors by measuring displacement, flow, volumetric efficiency of the hydraulic pump-hydraulic pump, hydraulic motors with given external conditions.

In this paper,we design the hydraulic system bench of the hydraulic pump and hydraulic motor, and calculate the related parameters , draw series of three-dimensional maps and two-dimensional drawings of the hydraulic pump and hydraulic motor,including Schematic experimental system, pump station assembly drawings, parts drawings of tank and valve block parts diagrams,which lay a theoretical foundation for the design of the hydraulic pump and hydraulic motor hydraulic system bench.

Key words hydraulic pump; hydraulic motor; hydraulic system
