一、概述随着科学技术的的飞速发展,液压传动、传力被广泛应用到各类机械中.机、电、液一体化的机械越来越多,液压系统越来越复杂.由于使用年限增加,液压系统的故障越来越多,很多故障难以解决,影响了工农业生产.有些进口机具液压件难以购买,而且液压件价格越来越昂贵,液压系统(件)的维修日益突出.新疆农垦科学院农机研究所根据目前社会的需要,发挥技术优势,成立了液压维修服务中心.专门为全兵团乃至全疆各种机械的液压系统(件)提供液压维修、技术服务和配件供应等.在成立之初,首先碰到的难题就是没有合适的液压试验台,无法对修复前后的液压件进行检测、鉴定.为了保证维修质量,正确判断故障原因及部位,根据维修行业的特殊要求.我们研制成功了YS—21液压综合试验台.该试验台于1996年1月通过了兵团科委组织的科研成果鉴定,专家认为达到自治区领先水平.二、试验台性能YS—21液压综合试验台可以分别完成液压泵、液压缸、压力阀、流量阀、换向阀、方向阀及液压马达等元件的测试试验,测试精度达到国家标准C级精
First, an overview With the rapid development of science and technology, hydraulic transmission, transmission force is widely used in various types of machinery.Machinery, electricity, liquid more and more integrated machinery, hydraulic system more and more complex.As the service life Increase, the hydraulic system more and more failures, many problems difficult to solve, affecting the industrial and agricultural production.Some imported hydraulic equipment is difficult to buy, and the hydraulic parts more and more expensive, the hydraulic system (parts) maintenance is increasingly prominent. Xinjiang Agricultural Reclamation Academy of Agriculture Institute of Agricultural Machinery according to the needs of the community, to play a technological superiority, the establishment of a hydraulic repair service center for the Corps and even a variety of mechanical Xinjiang’s hydraulic system (pieces) to provide hydraulic maintenance, technical services and accessories supply. At the beginning of the establishment, the first problem encountered was that there was no suitable hydraulic test bench and could not detect or identify the hydraulic parts before and after the repair. In order to ensure the quality of maintenance and correctly determine the cause and location of the malfunction, according to the special requirements of the maintenance industry, Successfully YS-21 hydraulic comprehensive test bed. The test bed in January 1996 adopted by the Corps Science and Technology Commission organized scientific research appraisal, experts believe that to achieve The leading level of the region. Second, the test bed performance YS-21 hydraulic comprehensive test stand can be completed respectively hydraulic pump, hydraulic cylinder, pressure valve, flow valve, valve, directional valve and hydraulic motor and other components of the test, the test accuracy National standard C grade fine
