講解SMC電氣比例閥,SMC參數范圍

產(chan)品(pin)作用:

這(zhe)種傳統的(de)氣(qi)(qi)動控(kong)(kong)制(zhi)(zhi)系統要想要有(you)多(duo)(duo)個(ge)輸出力和(he)多(duo)(duo)個(ge)運動速度，就需要多(duo)(duo)個(ge)減壓(ya)閥(fa)、節流(liu)閥(fa)及換(huan)向閥(fa)。這(zhe)樣，不僅元件(jian)需要多(duo)(duo)，成(cheng)本高，構成(cheng)系統復雜，且許多(duo)(duo)元件(jian)都需要預*行人工調節。而電氣(qi)(qi)比(bi)例閥(fa)控(kong)(kong)制(zhi)(zhi)屬于(yu)連續(xu)控(kong)(kong)制(zhi)(zhi)，其(qi)特點是輸出量(liang)(liang)(liang)隨輸入(ru)量(liang)(liang)(liang)(電流(liu)值(zhi)(zhi)或電壓(ya)值(zhi)(zhi))的(de)變(bian)化而變(bian)化，輸出量(liang)(liang)(liang)與輸入(ru)量(liang)(liang)(liang)之(zhi)間存在一定的(de)比(bi)例關系。比(bi)例控(kong)(kong)制(zhi)(zhi)有(you)開(kai)環控(kong)(kong)制(zhi)(zhi)和(he)閉(bi)環控(kong)(kong)制(zhi)(zhi)之(zhi)分。閉(bi)環控(kong)(kong)制(zhi)(zhi)有(you)信號的(de)反饋(kui)系統。

輸入(ru)信(xin)(xin)號(hao)(hao)增大，供(gong)氣(qi)用(yong)電(dian)(dian)磁(ci)先(xian)導(dao)閥(fa)1換(huan)向，而排氣(qi)先(xian)導(dao)閥(fa)7處(chu)于(yu)復位狀(zhuang)態，則(ze)供(gong)氣(qi)氣(qi)壓(ya)(ya)力(li)(li)從(cong)SUP口(kou)通過(guo)閥(fa)1進入(ru)先(xian)導(dao)室5，先(xian)導(dao)室壓(ya)(ya)力(li)(li)上(shang)升，氣(qi)壓(ya)(ya)力(li)(li)作(zuo)用(yong)在(zai)膜片(pian)2的上(shang)方，則(ze)和膜片(pian)2相連的供(gong)氣(qi)閥(fa)芯4便開(kai)啟，排氣(qi)閥(fa)芯3關(guan)閉，產生(sheng)輸出(chu)壓(ya)(ya)力(li)(li)。此(ci)輸出(chu)壓(ya)(ya)力(li)(li)通過(guo)傳感器6反饋至控制回路8.在(zai)這里，與目標(biao)值進行快速比(bi)較修正(zheng)，直(zhi)到輸出(chu)壓(ya)(ya)力(li)(li)與輸入(ru)電(dian)(dian)信(xin)(xin)號(hao)(hao)成(cheng)一定比(bi)例為止，從(cong)而得(de)到輸出(chu)壓(ya)(ya)力(li)(li)與輸入(ru)電(dian)(dian)信(xin)(xin)號(hao)(hao)的變化成(cheng)比(bi)例變化。由于(yu)沒有使(shi)用(yong)噴嘴(zui)擋板機(ji)構(gou)，故(gu)閥(fa)對雜志不敏感，可靠性高(gao)。
