SMC電磁閥的使用電壓
SMC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)可使用(yong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)壓也比(bi)較廣泛，常(chang)見的(de)(de)有直(zhi)流(liu)(liu)(liu)(liu)(liu)12V、24V；交(jiao)(jiao)流(liu)(liu)(liu)(liu)(liu)110V、220V，還有100V、200V等，此外SMC還可定(ding)制電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)的(de)(de)使用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)壓。交(jiao)(jiao)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)有蜂鳴(ming)聲，行(xing)程大(da)，吸力大(da)。直(zhi)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)不存在蜂鳴(ming)聲，行(xing)程大(da)時(shi)，吸力很(hen)小(xiao)，即啟動(dong)力小(xiao)。交(jiao)(jiao)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)氣動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)大(da)，有時(shi)是保持(chi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)的(de)(de)10倍以(yi)上，若動(dong)鐵(tie)(tie)心(xin)被(bei)卡住，啟動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)持(chi)續流(liu)(liu)(liu)(liu)(liu)過(guo)，線(xian)(xian)圈(quan)(quan)(quan)發(fa)熱厲害，甚(shen)被(bei)燒(shao)毀。交(jiao)(jiao)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)不宜(yi)頻繁通斷。壽命不及直(zhi)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)長。直(zhi)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)閥(fa)(fa)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)取決于線(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)(dian)(dian)(dian)(dian)阻，與行(xing)程大(da)小(xiao)無關。故動(dong)鐵(tie)(tie)心(xin)卡住時(shi)不會(hui)燒(shao)毀線(xian)(xian)圈(quan)(quan)(quan)。直(zhi)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)可頻繁通斷，工作安全可靠。但錯節高電(dian)(dian)(dian)(dian)(dian)(dian)壓，流(liu)(liu)(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)過(guo)大(da)時(shi)，仍會(hui)燒(shao)毀線(xian)(xian)圈(quan)(quan)(quan)。

SMC電磁閥的動作方式
SMC電磁閥按照動作方式可以分為直動式和導式。什么是直動式電磁閥呢？SMC直動式電磁閥直接依靠電磁力使閥芯換向。SMC直動式電磁閥通徑較小，常用于小流量控制或作為導式電磁閥的電磁導閥。SMC導式電磁閥由導閥和主閥組成。依靠導閥輸出的氣壓力，通過控制活塞等推動主閥芯換向。通徑大的SMC電磁閥大多為導式電磁閥。SMC導式電磁閥又分為內部導式電磁閥和外部導式電磁閥。
SMC電磁閥的接線方式
SMC電磁閥接線方式多種多樣，有直接出線方式，例如G、M、L；有接線座出線式；有導管接線座式；有DIN形插座式；有L形和M形插座式等。還有幾種配線方式等等。
SMC電(dian)磁閥(fa)在電(dian)磁線圈(quan)通(tong)電(dian)時，靜鐵心對動鐵心產(chan)生電(dian)磁吸力(li)，利用電(dian)磁力(li)使閥(fa)芯切換，以改變氣體流動方向(xiang)，從而實現(xian)通(tong)斷、換向(xiang)等。SMC電(dian)磁閥(fa)易于實現(xian)電(dian)-氣聯(lian)合控(kong)制和(he)復雜控(kong)制，能實現(xian)遠距(ju)離操(cao)作，故目前應用SMC電(dian)磁閥(fa)得到越(yue)來越(yue)廣泛(fan)的應用。

SMC電磁閥的常通式和常閉式
2通(tong)(tong)(tong)和3通(tong)(tong)(tong)SMC電磁(ci)閥有常通(tong)(tong)(tong)式(shi)(shi)和常閉式(shi)(shi)之分。無控制信號時，P、A相(xiang)同為常通(tong)(tong)(tong)式(shi)(shi)（般用N.O.表示）；P、A斷(duan)(duan)開(kai)則為常斷(duan)(duan)式(shi)(shi)（般用N.C.表示）。若通(tong)(tong)(tong)道內的流動方向不(bu)限定，則稱為通(tong)(tong)(tong)斷(duan)(duan)式(shi)(shi)閥。常通(tong)(tong)(tong)式(shi)(shi)和常斷(duan)(duan)式(shi)(shi)SMC電磁(ci)閥，不(bu)得逆向流動，因逆向壓力會造(zao)成(cheng)單向型(xing)密(mi)(mi)封圈(quan)不(bu)密(mi)(mi)封或密(mi)(mi)封失效。
