多路阀型式试验台的设计与开发

针对以型式试验为主的液压元件综合试验平台的设计问题,以叉车液压多路换向阀为例,通过分析国内厂家已有综合试验台的设计经验,主要集中在结构设计方面如快换接头设计,检测环节上如传感器测量技术应用等方面,对系统功能模块进行了集成化设计,并利用计算机LabVIEW软件实现了测试系统的自动控制以及试验数据实时显示与采集保存。实践结果证明,该试验设计中通过采用称重测量设备使测试结果具有较高的精确度,多种传感器的应用实时显示了系统的动态参数。研究结果表明,该新型型式试验台既满足了企业内部对液压元件各项性能的试验验证,同时也可为同行业的同类产品提供了检测服务与质量认证。

Design and development of type testing platform of multi-way valve

Aiming at the analysis and design about the integrated test platform which applied to the type testing on hydraulic components,the hydraulic multi-way directional valve of forklift truck was taken as an example,through the analysis of the domestic manufacturers＇comprehensive test-bed design experience,which were mainly focused on the structural design,such as the quick joint,the process of testing,and application of sensor technology and so on.The functional modules of system was designed comprehensively,meanwhile,the LabVIEW software was used in computer to achieve the testing system of automatic control,displaying in real time for the test data and the collection and preservation,etc..It＇s been proved that,the test platform has used weighing measuring test results with high accuracy,the application of multiple sensor helps to display the real-time dynamic parameters of the system.The results indicate that,the test platform can not only meet the enterprise＇s internal hydraulic components of various performance test,but also provide the testing services and quality certification for industry products.
