摘　　要：根据液压阀的泄漏测试要求,设计了测试系统的液压原理图,并基于LabVIEW软件平台,开发了一套基于视觉检测的液压阀泄漏量的自动检测系统,实现了自动化检测。试验结果表明:在不同压力下对液压阀的泄漏量进行检测,其测试结果误差在±0.1ml内。According to the requirements of hydraulic valve leakage test,the hydraulic schematic diagram of the test system is designed.Based on LabVIEW software platform,an automatic detection system of hydraulic valve leakage based on visual inspection is developed,which realizes automatic detection.The test results show that the error of the test results is within±0.1ml when the leakage of the overflow hydraulic valve is detected under differ­ent pressures.
