基于LabVIEW的控制阀性能测试评估系统设计

控制阀在工业控制领域扮演十分重要的角色,但目前国内对控制阀性能测试评估系统的研究十分薄弱,常规的仪器仪表很难精确测试控制阀的性能。本文基于NI compactRIO硬件、各类传感器以及Labview软件开发设计了一套控制阀性能测试评估系统,该系统实现了控制阀的在线测试和功能评估,并且可将控制阀各项性能指标评估结果汇集于一张类似体检单的报表显示。采用该系统对某公司的直通气开式薄膜调节阀S9044进行了性能测试评估,实验结果表明,该系统能够精确地测试出调节阀的各项性能指标,且系统软件交互界面良好、扩展性强、精度高。

The Development of Performance Test and Evaluation System of Control Valve

The control valve is very important in the field of industrial control. while the research on the control valve performance testing and evaluation system is very weak at present. It is very difficult to measure the performance of the control valve accurately by conventional instruments. This paper has developed a control valve performance test and evaluation system Based on NI CompactRIO hardware, various sensors and Labview software, the system can test and evaluate the function of control valves on-line, and can collect the results of the performance evaluation of the control valve in a real-time display similar to the medical report. Using this system, the performance test and evaluation of a company''s direct air open film regulator S9044 were carried out. Experimental results show that the system can fully and accurately test the performance indicators of the control valve, at the same time, the system has a good interactive interface, strong expansibility, and high precision.
