SMC電磁閥的三根(gen)線分別(bie)是什么線

一、SMC電磁閥三根(gen)線含義

SMC電(dian)磁閥(fa)是一種(zhong)電(dian)磁控(kong)(kong)制(zhi)(zhi)裝置(zhi)，通(tong)常由(you)閥(fa)體、電(dian)磁鐵(tie)、開關(guan)裝置(zhi)等部分組成。電(dian)磁閥(fa)可以通(tong)過控(kong)(kong)制(zhi)(zhi)電(dian)磁線圈的通(tong)斷(duan)，來控(kong)(kong)制(zhi)(zhi)液壓、氣壓等介(jie)質的流通(tong)或截斷(duan)。

SMC電(dian)磁閥的三(san)根線(xian)(xian)分別是(shi)控(kong)制線(xian)(xian)、電(dian)源(yuan)線(xian)(xian)和(he)公共線(xian)(xian)。其(qi)中，控(kong)制線(xian)(xian)一般為單色線(xian)(xian)（通常是(shi)黑色或紅(hong)色），用于(yu)接控(kong)制信號，電(dian)源(yuan)線(xian)(xian)和(he)公共線(xian)(xian)均為雙色線(xian)(xian)（通常為黑色和(he)白色或紅(hong)色和(he)藍色），用于(yu)接交流電(dian)源(yuan)。其(qi)中，電(dian)源(yuan)線(xian)(xian)為電(dian)源(yuan)正極(ji)，公共線(xian)(xian)為電(dian)源(yuan)負極(ji)。

二、三根線的功能(neng)分(fen)別是什么？

控(kong)(kong)制(zhi)(zhi)線(xian)(xian)：控(kong)(kong)制(zhi)(zhi)線(xian)(xian)是電(dian)(dian)(dian)(dian)磁閥控(kong)(kong)制(zhi)(zhi)的重(zhong)要組成部分，用于控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)磁鐵的通斷，從(cong)而控(kong)(kong)制(zhi)(zhi)介質的流(liu)通或(huo)截(jie)斷。當(dang)控(kong)(kong)制(zhi)(zhi)線(xian)(xian)接通電(dian)(dian)(dian)(dian)源時，電(dian)(dian)(dian)(dian)磁鐵會吸(xi)合，使(shi)閥門打開(kai)或(huo)關閉。控(kong)(kong)制(zhi)(zhi)線(xian)(xian)的電(dian)(dian)(dian)(dian)壓不(bu)宜過高，一般為或(huo)DC24V。

電(dian)源(yuan)線(xian)和公(gong)共線(xian)：電(dian)源(yuan)線(xian)和公(gong)共線(xian)主要用于(yu)給電(dian)磁(ci)(ci)閥供電(dian)。當(dang)電(dian)源(yuan)線(xian)和公(gong)共線(xian)接(jie)通電(dian)源(yuan)時(shi)，電(dian)磁(ci)(ci)鐵(tie)會受到電(dian)磁(ci)(ci)力(li)的作用，從而控制閥門(men)的開(kai)閉。在(zai)正(zheng)常情(qing)況(kuang)下(xia)，電(dian)源(yuan)線(xian)和公(gong)共線(xian)的電(dian)壓一般(ban)為AC220V或(huo)AC110V。

三、為什么電磁閥(fa)要用(yong)三根線？

SMC電(dian)(dian)(dian)磁(ci)閥之(zhi)所以(yi)用三根(gen)(gen)線(xian)(xian)(xian)(xian)(xian)，是(shi)因為(wei)(wei)控(kong)制(zhi)線(xian)(xian)(xian)(xian)(xian)需要接通(tong)控(kong)制(zhi)信號，控(kong)制(zhi)線(xian)(xian)(xian)(xian)(xian)的(de)電(dian)(dian)(dian)壓一般較(jiao)低(di)，而電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)(xian)(xian)和(he)公(gong)(gong)共線(xian)(xian)(xian)(xian)(xian)的(de)電(dian)(dian)(dian)壓一般較(jiao)高(gao)，為(wei)(wei)AC220V或AC380V。如果控(kong)制(zhi)線(xian)(xian)(xian)(xian)(xian)和(he)電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)(xian)(xian)或公(gong)(gong)共線(xian)(xian)(xian)(xian)(xian)在同一線(xian)(xian)(xian)(xian)(xian)纜中(zhong)，會產生干擾(rao)和(he)誤(wu)操作(zuo)，容易損壞電(dian)(dian)(dian)磁(ci)閥。因此(ci)，電(dian)(dian)(dian)磁(ci)閥采用三根(gen)(gen)線(xian)(xian)(xian)(xian)(xian)的(de)方式，控(kong)制(zhi)線(xian)(xian)(xian)(xian)(xian)和(he)電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)(xian)(xian)或公(gong)(gong)共線(xian)(xian)(xian)(xian)(xian)分開，避免干擾(rao)和(he)損壞。

總之，SMC電(dian)磁(ci)閥(fa)的三根線(xian)(xian)(xian)分(fen)別(bie)對(dui)應控制線(xian)(xian)(xian)、電(dian)源線(xian)(xian)(xian)和(he)公共線(xian)(xian)(xian)，不(bu)同(tong)的線(xian)(xian)(xian)路分(fen)別(bie)用(yong)于控制電(dian)磁(ci)閥(fa)的開(kai)啟和(he)關閉，保證電(dian)磁(ci)閥(fa)的正常運行。

1、電(dian)源(yuan)接(jie)線(xian)(xian)：將(jiang)開關電(dian)源(yuan)提供的24V電(dian)源(yuan)的接(jie)到控制電(dian)源(yuan)端(duan)(duan)，24V負(fu)極接(jie)地線(xian)(xian)EG端(duan)(duan)子(zi)，正極接(jie)24V端(duan)(duan)子(zi)。PE是(shi)保護(hu)(hu)接(jie)地端(duan)(duan)子(zi)接(jie)安全保護(hu)(hu)地線(xian)(xian)。

2、輸(shu)出(chu)接(jie)(jie)線：輸(shu)出(chu)直接(jie)(jie)連接(jie)(jie)電(dian)磁閥或其他電(dian)器負載，分別接(jie)(jie)到DC+與Y輸(shu)出(chu)端子上。

3、輸入接線：開關信號直接連(lian)接到輸入端(duan)(duan)子的(de)X輸入與地(di)線EG端(duan)(duan)。帶電(dian)源(yuan)的(de)傳(chuan)感器的(de)電(dian)源(yuan)端(duan)(duan)接+E端(duan)(duan)子或+24V端(duan)(duan)子，地(di)線接EG端(duan)(duan)，輸出端(duan)(duan)接X輸入端(duan)(duan)。

電磁閥符號是指對(dui)電磁閥功能(neng)進(jin)行描述的(de)示意(yi)圖，通常應用(yong)于氣動(dong)系(xi)統設計(ji)及產(chan)品標識上，以供氣動(dong)系(xi)統設計(ji)人(ren)員及電磁閥使(shi)用(yong)者(zhe)了解產(chan)品功能(neng)。

在設(she)計過程(cheng)中，常(chang)常(chang)需(xu)要(yao)看氣路圖。各(ge)(ge)種電磁閥(fa)(fa)化(hua)身為各(ge)(ge)自(zi)相應的(de)氣動符(fu)號出現在圖紙上，這(zhe)種表示(shi)方式(shi)，就是(shi)電磁閥(fa)(fa)符(fu)號。

示例及說明：

附圖：從(cong)上至(zhi)下從(cong)左到右分別是

直動式：兩位兩通(tong)，兩位三通(tong)常通(tong)，兩位三通(tong)常斷 。

先導式：兩(liang)(liang)(liang)位(wei)兩(liang)(liang)(liang)通，兩(liang)(liang)(liang)位(wei)三通常(chang)(chang)通，兩(liang)(liang)(liang)位(wei)三通常(chang)(chang)斷 。

電磁閥符號解釋

前面(mian)的(de)(de)“幾(ji)位(wei)"，你要看這個(ge)閥有(you)幾(ji)種(zhong)工作狀態，就(jiu)可以說是幾(ji)位(wei)，如有(you)氣動元(yuan)件符號(hao)，就(jiu)更(geng)好理解了，在(zai)(zai)圖符上代表閥體(ti)的(de)(de)正方(fang)(fang)形(內有(you)箭頭或T線(xian))有(you)幾(ji)個(ge)就(jiu)是幾(ji)位(wei)。而后面(mian)的(de)(de)“幾(ji)通(tong)"，是代表在(zai)(zai)其中的(de)(de)一個(ge)正方(fang)(fang)形上有(you)幾(ji)個(ge)點(dian)（和(he)箭頭線(xian)還有(you)T線(xian)相(xiang)交的(de)(de)點(dian)），就(jiu)是幾(ji)通(tong)。

氣動電磁閥圖形符號

磁閥圖形(xing)符號的含義一般如下：

1、用方框表示閥(fa)的(de)工作位(wei)置(zhi)，有幾個(ge)方框就(jiu)表示有幾“位(wei)";

2、方(fang)框內的(de)箭頭表示(shi)(shi)油路處于接(jie)通狀態，但箭頭方(fang)向不(bu)一定表示(shi)(shi)液流的(de)實際方(fang)向；

3、方框(kuang)內符號“┻"或“┳"表(biao)示該通(tong)路不通(tong)；

4、方框外部連接的接口數有幾個，就表示幾“通"；

5、一(yi)般(ban)，閥(fa)(fa)與系(xi)統供油(you)路或氣路連(lian)接的進(jin)油(you)口/進(jin)氣口用字母p表(biao)(biao)示(shi)(shi)；閥(fa)(fa)與系(xi)統回(hui)油(you)路/氣路連(lian)通的回(hui)油(you)/回(hui)氣口用t（有時(shi)用o）表(biao)(biao)示(shi)(shi);而(er)閥(fa)(fa)與執行元件連(lian)接的油(you)口/氣口用a、b等表(biao)(biao)示(shi)(shi)。有時(shi)在圖形符號上(shang)用l表(biao)(biao)示(shi)(shi)泄漏油(you)口；

6、換向(xiang)閥都有(you)兩個或兩個以上(shang)的(de)工作位置，其中(zhong)一個為常(chang)態位，即(ji)閥芯未受到操(cao)縱力時所處(chu)的(de)位置。圖形(xing)符(fu)號中(zhong)的(de)中(zhong)位是(shi)三位閥的(de)常(chang)態位。利(li)用彈簧復位的(de)二位閥則以靠近(jin)彈簧的(de)方框內的(de)通路(lu)狀態為其常(chang)態位。繪制系統圖時，油(you)路(lu)/氣路(lu)一般應連(lian)接在換向(xiang)閥的(de)常(chang)態位上(shang)。
