        氣動(dòng)球閥狀態(tài)監(jiān)測實(shí)驗(yàn)系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn)
       據(jù)此設(shè)計(jì)了一套實(shí)驗(yàn)系統(tǒng),該系統(tǒng)主要由氣源、減壓閥、截止閥、二位五通電磁閥、氣動(dòng)球閥等各個(gè)部件和球閥狀態(tài)監(jiān)測系統(tǒng)組成??刂茪怏w為氮?dú)?,壓力? MPa。
       氣動(dòng)球閥狀態(tài)監(jiān)測系統(tǒng)主要包括傳感器和信號(hào)控制與數(shù)據(jù)采集單元,傳感器包括3個(gè)壓力傳感器和1個(gè)位移傳感器,3個(gè)壓力傳感器分別實(shí)現(xiàn)二位五通電磁閥入口、球閥進(jìn)氣口、球閥出氣口處氣體壓力的測試,直接對(duì)球閥轉(zhuǎn)角進(jìn)行測試較為困難, 因此轉(zhuǎn)化為對(duì)直線位移的測試,由1個(gè)位移傳感器完成測試。信號(hào)控制與數(shù)據(jù)采集系統(tǒng)用于給電磁閥加入啟動(dòng)信號(hào)(階躍信號(hào)),并進(jìn)行數(shù)據(jù)的采集,采樣頻率設(shè)置為2 kHz。
