SMC電磁(ci)閥(fa)國內生產制(zhi)造的全(quan)過程中發生的難題及處理

　　對SMC電磁閥構件構造開展改(gai)善，在(zai)鐵(tie)心(xin)(xin)的下邊加一(yi)O形密(mi)封環，確保(bao)沒有油、水等臟污進到(dao)導桿與(yu)鐵(tie)心(xin)(xin)中(zhong)(zhong)間的空(kong)隙。進而做到(dao)操縱閥芯在(zai)鐵(tie)心(xin)(xin)中(zhong)(zhong)輕(qing)松滾(gun)動，確保(bao)了空(kong)氣壓縮機污水處(chu)理靠譜。

　　SMC電(dian)(dian)(dian)磁閥(fa)根據一橋式電(dian)(dian)(dian)路整流器成(cheng)20V直流電(dian)(dian)(dian)功效(xiao)(xiao)于輸(shu)出(chu)功率約30W的直流線(xian)圈(quan)上。插電(dian)(dian)(dian)后電(dian)(dian)(dian)磁線(xian)圈(quan)造成(cheng)電(dian)(dian)(dian)磁力功效(xiao)(xiao)到鐵心(xin)上，鐵心(xin)推動操縱閥(fa)芯引向(xiang)高壓(ya)閘閥(fa)完成(cheng)密(mi)封性(xing)，電(dian)(dian)(dian)磁閥(fa)關掉。

　　SMC電(dian)(dian)磁閥跳停的(de)一瞬(shun)間，電(dian)(dian)磁線圈上(shang)的(de)用電(dian)(dian)量要瞬(shun)間釋放(fang)出來(lai)會(hui)造成(cheng)最高(gao)(gao)(gao)值(zhi)很高(gao)(gao)(gao)的(de)反方向工(gong)作電(dian)(dian)壓，該工(gong)作電(dian)(dian)壓功效到整(zheng)流(liu)(liu)二(er)極(ji)(ji)(ji)(ji)(ji)管(guan)上(shang)面(mian)有很有可能會(hui)穿透二(er)極(ji)(ji)(ji)(ji)(ji)管(guan)。因此采(cai)用耐髙壓的(de)二(er)極(ji)(ji)(ji)(ji)(ji)管(guan)，并(bing)對橋(qiao)式整(zheng)流(liu)(liu)電(dian)(dian)源(yuan)電(dian)(dian)路開展了改(gai)善，在橋(qiao)式電(dian)(dian)路上(shang)與(yu)負(fu)荷串聯一型號(hao)規格SMC電(dian)(dian)磁閥的(de)雙重(zhong)二(er)極(ji)(ji)(ji)(ji)(ji)管(guan)，用于釋放(fang)出來(lai)以上(shang)最高(gao)(gao)(gao)值(zhi)反方向工(gong)作電(dian)(dian)壓以維護(hu)整(zheng)流(liu)(liu)二(er)極(ji)(ji)(ji)(ji)(ji)管(guan)。很切實(shi)解(jie)決了整(zheng)流(liu)(liu)二(er)極(ji)(ji)(ji)(ji)(ji)管(guan)被穿透難題。

　　電源開關輕松、靈巧靠譜(pu)，才可(ke)以合理操縱污水處理主閥開啟或(huo)關掉，完(wan)成按時污水處理，確保(bao)制冷壓縮機(ji)一(yi)切正常工(gong)作中。

　　在SMC電磁閥的早期應用全過程中，有時候(hou)發(fa)生電磁閥開啟后(hou)，關掉時密封性(xing)不(bu)緊(jin)。拆(chai)檢后(hou)發(fa)覺操縱(zong)閥芯的導桿(gan)(gan)生繡，不(bu)可以在鐵(tie)心(xin)(xin)中輕松滾動，它是因為污水(shui)處理時有油、水(shui)等臟污隨氣(qi)一起(qi)進到導桿(gan)(gan)與(yu)鐵(tie)心(xin)(xin)中間(jian)的空隙(xi)，會(hui)使導桿(gan)(gan)造成生銹。

　　現在(zai)，讓我們看一(yi)下執行器(qi)的基本類型，然(ran)后決定我們需要哪種類型的螺(luo)線管來操作它們。大多數氣(qi)動(dong)閥執行器(qi)屬于兩類之一(yi)：雙作用(就位(wei)故障)或彈簧復(fu)位(wei)(故障打開(kai)或故障關閉)。許多氣(qi)動(dong)執行器(qi)由位(wei)于氣(qi)缸內的一(yi)個或兩個活(huo)塞組成，該氣(qi)缸連(lian)接到操作閥的桿或小齒(chi)輪上。

　　SMC電磁(ci)閥也有一(yi)些膜(mo)(mo)片執(zhi)行器(qi)利(li)用橡膠膜(mo)(mo)片，該膜(mo)(mo)片的(de)(de)(de)彈(dan)簧(huang)(huang)附在(zai)桿上，該彈(dan)簧(huang)(huang)操縱閥。彈(dan)簧(huang)(huang)復(fu)位(wei)執(zhi)行器(qi)在(zai)活(huo)塞(sai)(sai)的(de)(de)(de)末端具有彈(dan)簧(huang)(huang)，當(dang)空(kong)氣(qi)從執(zhi)行器(qi)中排出時，彈(dan)簧(huang)(huang)將活(huo)塞(sai)(sai)返(fan)回(hui)到特(te)定位(wei)置。向(xiang)活(huo)塞(sai)(sai)或隔膜(mo)(mo)的(de)(de)(de)一(yi)側(ce)添加(jia)空(kong)氣(qi)時，必須從另(ling)一(yi)側(ce)排出空(kong)氣(qi)，以(yi)使(shi)活(huo)塞(sai)(sai)或隔膜(mo)(mo)移(yi)動并操作(zuo)閥。如果不(bu)對(dui)執(zhi)行器(qi)進(jin)行排氣(qi)，則(ze)不(bu)會使(shi)閥門(men)行程。當(dang)執(zhi)行器(qi)返(fan)回(hui)其正常位(wei)置時，您還必須排氣(qi)活(huo)塞(sai)(sai)或隔膜(mo)(mo)的(de)(de)(de)壓力側(ce)。

　　SMC電(dian)(dian)磁閥現代齒條齒輪執(zhi)行(xing)(xing)(xing)機(ji)構具(ju)有通用(yong)(yong)的(de)供(gong)油口配(pei)置，允許使用(yong)(yong)特殊的(de)直接安裝螺(luo)線管(guan)來(lai)消除(chu)對管(guan)路(lu)或配(pei)件的(de)需求。遠程安裝螺(luo)線管(guan)可(ke)以(yi)安裝在(zai)執(zhi)行(xing)(xing)(xing)器上或附近，并(bing)且(qie)需要(yao)將空氣通過管(guan)道輸(shu)送到執(zhi)行(xing)(xing)(xing)器。如(ru)果執(zhi)行(xing)(xing)(xing)器處于惡劣或高(gao)溫(wen)的(de)環境(jing)中，可(ke)能會影響螺(luo)線管(guan)電(dian)(dian)子設備的(de)運行(xing)(xing)(xing)，則(ze)遠程安裝螺(luo)線管(guan)很有用(yong)(yong)。

　　SMC電(dian)(dian)(dian)磁閥術語“三(san)通(tong)(tong)"(左圖)，“四通(tong)(tong)"和“五通(tong)(tong)"是指電(dian)(dian)(dian)磁閥體內(nei)的(de)(de)端口(kou)配置。當(dang)電(dian)(dian)(dian)線(xian)圈(quan)通(tong)(tong)電(dian)(dian)(dian)或斷(duan)電(dian)(dian)(dian)時(shi)，這些(xie)端口(kou)將引(yin)導您的(de)(de)空(kong)氣(qi)(qi)(qi)供應(ying)以(yi)及執行器(qi)的(de)(de)排(pai)氣(qi)(qi)(qi)。例如，三(san)通(tong)(tong)螺線(xian)管(guan)具(ju)(ju)有一(yi)個(ge)壓力(li)(li)(li)入口(kou)，一(yi)個(ge)壓力(li)(li)(li)出口(kou)，用(yong)于(yu)操(cao)作氣(qi)(qi)(qi)動執行器(qi)(線(xian)圈(quan)通(tong)(tong)電(dian)(dian)(dian))，并且它具(ju)(ju)有一(yi)個(ge)排(pai)氣(qi)(qi)(qi)口(kou)，用(yong)于(yu)在(zai)線(xian)圈(quan)斷(duan)開時(shi)從(cong)執行器(qi)壓力(li)(li)(li)側釋放壓力(li)(li)(li)。三(san)通(tong)(tong)螺線(xian)管(guan)主要(yao)用(yong)于(yu)彈簧復位執行器(qi)。三(san)通(tong)(tong)電(dian)(dian)(dian)磁閥僅對執行器(qi)活(huo)塞(sai)的(de)(de)一(yi)側進(jin)行加壓和排(pai)氣(qi)(qi)(qi)。彈簧復位執行器(qi)通(tong)(tong)常在(zai)活(huo)塞(sai)或隔膜的(de)(de)非壓力(li)(li)(li)側具(ju)(ju)有內(nei)置的(de)(de)排(pai)氣(qi)(qi)(qi)孔。

　　SMC電磁(ci)閥具有(you)一(yi)個(ge)壓(ya)(ya)力入口(kou)(kou)，兩(liang)(liang)(liang)個(ge)壓(ya)(ya)力出(chu)(chu)口(kou)(kou)，并為執(zhi)行(xing)器(qi)活(huo)塞(sai)的(de)(de)兩(liang)(liang)(liang)側(ce)共享一(yi)個(ge)排(pai)氣口(kou)(kou)。一(yi)個(ge)五(wu)通(tong)(tong)(tong)(tong)電磁(ci)與四(si)(si)通(tong)(tong)(tong)(tong)相似，不同之處在于(yu)它們(men)具有(you)一(yi)個(ge)入口(kou)(kou)壓(ya)(ya)力端口(kou)(kou)，兩(liang)(liang)(liang)個(ge)出(chu)(chu)口(kou)(kou)壓(ya)(ya)力端口(kou)(kou)和兩(liang)(liang)(liang)個(ge)獨立的(de)(de)排(pai)氣端口(kou)(kou)。四(si)(si)通(tong)(tong)(tong)(tong)和五(wu)通(tong)(tong)(tong)(tong)螺(luo)(luo)線(xian)(xian)(xian)(xian)管主要用(yong)于(yu)雙(shuang)(shuang)作(zuo)用(yong)執(zhi)行(xing)器(qi)。它們(men)使(shi)(shi)您可(ke)以(yi)加壓(ya)(ya)和排(pai)氣執(zhi)行(xing)器(qi)活(huo)塞(sai)的(de)(de)每一(yi)側(ce)。四(si)(si)通(tong)(tong)(tong)(tong)和五(wu)通(tong)(tong)(tong)(tong)螺(luo)(luo)線(xian)(xian)(xian)(xian)管可(ke)以(yi)具有(you)一(yi)個(ge)或(huo)兩(liang)(liang)(liang)個(ge)電磁(ci)線(xian)(xian)(xian)(xian)圈。單線(xian)(xian)(xian)(xian)圈版本會導致執(zhi)行(xing)器(qi)無(wu)法關閉或(huo)因斷(duan)(duan)電而無(wu)法打開。如果斷(duan)(duan)電，雙(shuang)(shuang)線(xian)(xian)(xian)(xian)圈螺(luo)(luo)線(xian)(xian)(xian)(xian)管將使(shi)(shi)您的(de)(de)執(zhi)行(xing)器(qi)保持原位。如果沒有(you)四(si)(si)通(tong)(tong)(tong)(tong)或(huo)五(wu)通(tong)(tong)(tong)(tong)螺(luo)(luo)線(xian)(xian)(xian)(xian)管，可(ke)以(yi)使(shi)(shi)用(yong)兩(liang)(liang)(liang)個(ge)三(san)通(tong)(tong)(tong)(tong)螺(luo)(luo)線(xian)(xian)(xian)(xian)管獨立控制(zhi)雙(shuang)(shuang)作(zuo)用(yong)執(zhi)行(xing)器(qi)的(de)(de)每一(yi)側(ce)。此配置將復(fu)制(zhi)雙(shuang)(shuang)線(xian)(xian)(xian)(xian)圈螺(luo)(luo)線(xian)(xian)(xian)(xian)管的(de)(de)操(cao)作(zuo)。

　　通常，您(nin)將需要常閉(bi)螺線(xian)(xian)管(guan)(guan)來使(shi)執行器自動化(hua)。常閉(bi)或(huo)常開是指線(xian)(xian)圈斷(duan)(duan)電時(shi)(shi)螺線(xian)(xian)管(guan)(guan)的位置。當線(xian)(xian)圈斷(duan)(duan)電時(shi)(shi)，常閉(bi)螺線(xian)(xian)管(guan)(guan)將阻止執行器的空氣供應。當線(xian)(xian)圈斷(duan)(duan)電時(shi)(shi)，常開螺線(xian)(xian)管(guan)(guan)為供氣到達執行器提(ti)供了一條開放路(lu)徑(jing)。
