基于LabWindows/CVI的喷气织机引纬气流测试系统

Weft Insertion Air Flow Testing System of Air-jet Loom Based on LabWindows/CVI

根据引纬流场测试特点,基于虚拟仪器软件开发平台Lab Windows/CVI,使用L型总压探针、CYG101型固态压阻压力传感器和PCI-1232多功能数据采集卡,开发用于喷气织机的引纬气流动态测试系统,实现对织造过程中主喷嘴气流、辅助喷嘴气流和引纬汇交气流的动态压力的实时检测,并能按要求对采集的数据进行分析与处理。应用该测试系统,对主喷嘴气压、辅助喷嘴气压和汇交气流气压进行测试,并对测试结果进行分析。

According to the characteristics of weft insertion flow field testing,the weft insertion air flow dynamic testing system for air-jet loom was developed with L-type total pressure probe,CYG101 type solid-state piezoresistive pressure sensor and PCI-1232 multifunction data acquisition card,based on virtual instrument software development platform LabWindows/CVI.This test system was able to realize real-time detection of weft insertion air flow dynamic pressure of the main air nozzle or auxiliary nozzle in weaving process,and was able to analyse or deal with the collected data.This test system was used to test the air pressures of main nozzle,auxiliary nozzle and weft insertion air flow.The test results were analyzed.
