CKD電磁閥@CKD脈沖電磁閥的工作原理
產品介紹
脈沖電磁閥是脈沖袋式除塵器清灰噴吹系統的壓縮空氣“開關”，受脈沖噴吹控制儀輸出信號的控制,對濾袋逐排（室）噴吹清灰，使除塵器的阻力保持在設定的范圍之內,以保證除塵器的處理能力和收塵效率。下面小編給大家介紹一下脈沖電磁閥工作原理。
脈(mo)(mo)沖(chong)(chong)(chong)電(dian)磁(ci)閥通過導線(xian)將電(dian)磁(ci)閥體內(nei)(nei)線(xian)圈輸(shu)入(ru)正向(xiang)脈(mo)(mo)沖(chong)(chong)(chong)信號(hao)，線(xian)圈產生的工(gong)作(zuo)磁(ci)通，使動(dong)芯吸合，打(da)開(kai)閥門。當停止正向(xiang)脈(mo)(mo)沖(chong)(chong)(chong)信號(hao)輸(shu)入(ru)時(shi)，動(dong)芯釋放，動(dong)芯在彈簧力的作(zuo)用(yong)下(xia)回復到初始狀態，關閉閥門另外有自保(bao)持型的，停止輸(shu)入(ru)正向(xiang)脈(mo)(mo)沖(chong)(chong)(chong)或斷電(dian)后也能保(bao)持，需要輸(shu)入(ru)負向(xiang)脈(mo)(mo)沖(chong)(chong)(chong)信號(hao)才能復位；脈(mo)(mo)沖(chong)(chong)(chong)電(dian)磁(ci)閥的工(gong)作(zuo)原理，是(shi)利用(yong)電(dian)器的脈(mo)(mo)沖(chong)(chong)(chong)轉化(hua)為(wei)機械(xie)的脈(mo)(mo)動(dong)，使得脈(mo)(mo)動(dong)氣體的強大(da)能量變成動(dong)量，在短時(shi)間內(nei)(nei)釋放產生巨大(da)沖(chong)(chong)(chong)力，用(yong)plc控(kong)制其脈(mo)(mo)沖(chong)(chong)(chong)的間隔應根據額定(ding)氣體壓(ya)力恢復時(shi)間l來(lai)確定(ding).。

    脈沖(chong)閥受脈沖(chong)噴(pen)吹控(kong)制(zhi)儀輸(shu)出信(xin)號(hao)的(de)控(kong)制(zhi)，依靠閥的(de)前后(hou)兩(liang)個氣(qi)室的(de)壓力變(bian)化，使橡(xiang)膠(jiao)膜片曲撓變(bian)形(xing)實(shi)現脈沖(chong)閥的(de)開啟和(he)關(guan)閉(bi)。橡(xiang)膠(jiao)膜片的(de)直徑決(jue)定橡(xiang)膠(jiao)膜片的(de)行程大小及開啟和(he)關(guan)閉(bi)的(de)速度，膜片直徑越大其(qi)行程也大，噴(pen)吹性能也越好。
