基于插装阀的液压缸试验台设计

摘要

Since the test bed of big hydraulic cylinder needs high pressure and greater flow rate,the hydraulic cylinder test bed based on cartridge valves was designed according to the test standard of hydraulic cylinder and the deficiency of the existing hydraulic cylinder test bed in this paper.It have been proposed that the system of loading hydraulic cylinder and system of test hydraulic cylinder by using the same hydraulic source,so did the system with high pressure and greatflow rate in parallel which could reduce the motors and hydraulic pump. Therefore,the hydraulic cylinder test bed could be obtained which has some characteristics such as higher auto-mation,lower product costing and energy saving.%根据液压缸的试验标准和现有液压缸试验台的不足，针对大型液压缸试验台要求高压、大流量的特点，设计出基于插装阀的液压缸试验台，并考虑到设计方便及经济型要求，提出加载液压缸和被测液压缸采用同一个液压源、高压系统和大流量系统并联的方案，减少了电机以及液压泵的使用数量，减小了系统功率，设计出一套自动化程度高，制造成本低，节能的液压缸试验台系统。
