比例阀性能智能测试系统的研究

Research on performance test system of gas proportional valve

设计研制了一套基于工控机的燃气比例阀性能智能测试系统,其研究旨在为燃气比例阀的生产厂家或者质量监督部门提供一种先进的测试设备,以实现对燃气比例阀性能的测试。本系统是以工控机为核心,采用PCL—818L数据采集卡、24PCDFA6D压力传感器和AWM720P1热式质量流量传感器对燃气比例阀各性能参数进行测试,并绘制其特性曲线的工控机系统,实现对比例阀在出厂前进行稳压特性(p2—p1)、稳态控制特性(p2—I/Q—I)等性能的测试。

A test system of gas proportional valve based on industrial personal computer （IPC） is developed. This test system is used for manufactories and quality supervisory departments to do the test of gas proportional valve performance more quickly and conveniently. This IPC＇ s system uses PCL-818L data acquisition card, 24PCDFA6D pressure sensors and AWM720P1 thermal mass flow sensor to test the performances of gas proportional valve, and the curves of the performances are described. The performances include steady pressure performance P2-Pland controlling performance P2-1 or Q-I and so on.
