BURKERT電磁閥老是毛病不斷，如何正確處理呢？

　　BURKERT電(dian)磁(ci)閥老是(shi)毛病不斷，如何正確處(chu)理呢(ni)？

　　BURKERT電(dian)磁閥(fa)，如(ru)今在工(gong)業應用十分常(chang)見，特別是在石(shi)油、化工(gong)行業，很多工(gong)藝(yi)管道都要安(an)裝開關閥(fa)，又因為工(gong)作現場非常(chang)危險，相比(bi)其它行業對安(an)全要求更為苛刻，大型(xing)(xing)的(de)化工(gong)企(qi)業有專門的(de)儀表工(gong)，小型(xing)(xing)的(de)基本上都是電(dian)工(gong)來負責(ze)日常(chang)管理與維護。

　　這里說(shuo)的(de)(de)就是在這行業(ye)常用(yong)的(de)(de)氣(qi)動(dong)電磁閥(fa)，有(you)(you)的(de)(de)貼氣(qi)缸(gang)安裝，有(you)(you)的(de)(de)在氣(qi)缸(gang)旁邊采用(yong)支架安裝。氣(qi)動(dong)電磁閥(fa)能夠在這些高危行業(ye)應用(yong)廣泛，具(ju)有(you)(you)防火、防爆、安全性好、無污染等*性，是其它傳動(dong)部件(jian)(jian)不具(ju)備的(de)(de)。基本組成分電磁部件(jian)(jian)和閥(fa)體(ti)電磁部件(jian)(jian)；定鐵芯、動(dong)鐵芯，線(xian)圈。閥(fa)體(ti)；滑閥(fa)芯、滑閥(fa)套、彈簧底(di)座。

　　BURKERT電(dian)(dian)(dian)磁(ci)(ci)閥(fa)的(de)基本概述。兩位(wei)三通(tong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)工作過程；線圈得電(dian)(dian)(dian)，線圈勵(li)磁(ci)(ci)電(dian)(dian)(dian)磁(ci)(ci)鐵吸合，動鐵芯(xin)上部帶電(dian)(dian)(dian)彈(dan)簧的(de)密(mi)封塊借助(zhu)彈(dan)簧壓力將(jiang)排(pai)氣(qi)口關閉，壓縮空氣(qi)從進氣(qi)口進入(ru)閥(fa)門(men)(men)氣(qi)缸(gang)，起到(dao)控制(zhi)作用。失(shi)電(dian)(dian)(dian)時，電(dian)(dian)(dian)磁(ci)(ci)力消失(shi)，動鐵芯(xin)在彈(dan)簧作用力下(xia)(xia)離開(kai)固定鐵芯(xin)向下(xia)(xia)移(yi)動，將(jiang)排(pai)氣(qi)口打開(kai)，進氣(qi)口關閉，閥(fa)門(men)(men)氣(qi)缸(gang)因失(shi)氣(qi)而改(gai)變狀態。兩位(wei)四通(tong)、兩位(wei)五通(tong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)工作原理(li)與(yu)(yu)上述的(de)原理(li)相同(tong)，只是(shi)排(pai)氣(qi)口數不同(tong)。這里說的(de)兩位(wei)的(de)含(han)義；對(dui)(dui)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)自身來說，就是(shi)通(tong)電(dian)(dian)(dian)和失(shi)電(dian)(dian)(dian)，對(dui)(dui)所控制(zhi)的(de)閥(fa)門(men)(men)來說，就是(shi)開(kai)與(yu)(yu)關。幾通(tong)的(de)含(han)義；指的(de)是(shi)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)的(de)氣(qi)孔數，拿到(dao)實物一看一目了然。

　　BURKERT電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)的(de)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)有220V供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和24V供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，在高危行業采(cai)(cai)用(yong)(yong)24V供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)居多。綜合來說，各(ge)有各(ge)的(de)的(de)優(you)勢。采(cai)(cai)用(yong)(yong)220V供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，不利(li)于(yu)現(xian)場(chang)防爆，但有利(li)于(yu)遠距(ju)離傳(chuan)(chuan)輸(shu)(shu)。原因是供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)高，傳(chuan)(chuan)輸(shu)(shu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)造成的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降不會影(ying)響到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)正(zheng)常(chang)工作。采(cai)(cai)用(yong)(yong)24V供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，利(li)于(yu)現(xian)場(chang)防爆，但傳(chuan)(chuan)輸(shu)(shu)距(ju)離較(jiao)遠，得考慮傳(chuan)(chuan)輸(shu)(shu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)工作的(de)影(ying)響。因此，就(jiu)要根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)工作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)來計算傳(chuan)(chuan)輸(shu)(shu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)最(zui)大允許長度。

　　例如采(cai)(cai)用24V供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源，電(dian)(dian)(dian)(dian)(dian)(dian)磁閥工(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為20V，線(xian)(xian)(xian)路(lu)(lu)最(zui)大(da)允許電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降4V，額定功率12W，采(cai)(cai)用聚氯(lv)乙烯絕緣護套控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)纜，線(xian)(xian)(xian)徑(jing)2.5mm2，采(cai)(cai)用兩線(xian)(xian)(xian)制(zhi)。計算電(dian)(dian)(dian)(dian)(dian)(dian)磁閥工(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)I＝0.5A允許控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)纜最(zui)大(da)長(chang)度L的(de)計算通(tong)過(guo)查表，得知控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)纜最(zui)大(da)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)阻7.1Ω/Km，又(you)因(yin)為線(xian)(xian)(xian)路(lu)(lu)產生電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降的(de)電(dian)(dian)(dian)(dian)(dian)(dian)阻R＝8Ω，因(yin)此(ci)，最(zui)大(da)允許控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)纜長(chang)度為1.079Km。又(you)因(yin)為采(cai)(cai)用的(de)是兩線(xian)(xian)(xian)制(zhi)控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)纜，因(yin)此(ci)每根控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)纜長(chang)度為539m。通(tong)過(guo)理論(lun)計算，得知電(dian)(dian)(dian)(dian)(dian)(dian)磁閥不低于正(zheng)常(chang)工(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)20V時，采(cai)(cai)用2.5mm2的(de)線(xian)(xian)(xian)傳輸距離最(zui)長(chang)可(ke)達到539m。

　　BURKERT電磁閥應用過程常見故障

　　BURKERT電(dian)(dian)(dian)(dian)磁(ci)閥(fa)接線頭松動及(ji)脫落(luo)(luo)，線圈燒壞(huai)(huai)，電(dian)(dian)(dian)(dian)磁(ci)閥(fa)卡(ka)住(zhu)(zhu)。電(dian)(dian)(dian)(dian)磁(ci)閥(fa)接線松動及(ji)脫落(luo)(luo)，這個從(cong)新緊固，對于線圈燒壞(huai)(huai)，看線圈頭子(zi)發光二極管的亮滅或用金屬(shu)物體插入線圈孔是否吸合，電(dian)(dian)(dian)(dian)磁(ci)閥(fa)線圈損壞(huai)(huai)更換。對于電(dian)(dian)(dian)(dian)磁(ci)閥(fa)卡(ka)住(zhu)(zhu)問(wen)題，將滑(hua)閥(fa)芯、滑(hua)閥(fa)套、彈簧底座拆掉，進行清理，清理完成(cheng)再(zai)涂(tu)抹潤滑(hua)脂。原因是排氣(qi)口沒(mei)有裝(zhuang)消音器(qi)，空氣(qi)中的雜質進入閥(fa)門，或者(zhe)壓縮空氣(qi)不夠干凈，含有雜質，水、油(you)及(ji)其它污垢(gou)。

　　解(jie)決(jue)時，BURKERT電(dian)(dian)磁閥排氣(qi)口沒有裝(zhuang)消(xiao)音(yin)器給予安裝(zhuang)，電(dian)(dian)磁閥進氣(qi)前段(duan)應裝(zhuang)空(kong)氣(qi)過(guo)濾減壓(ya)閥。空(kong)氣(qi)過(guo)濾減壓(ya)閥的(de)好處，可以濾除(chu)雜質，吸收壓(ya)縮(suo)空(kong)氣(qi)含有水、油等，從(cong)而凈化壓(ya)縮(suo)空(kong)氣(qi)，避免對電(dian)(dian)磁閥閥體(ti)及氣(qi)缸(gang)帶(dai)來不可必要的(de)損壞。

　　空(kong)氣(qi)過濾(lv)減(jian)壓(ya)閥(fa)，除(chu)了上述之外還可(ke)以進(jin)行(xing)調壓(ya)。一般工廠所用的壓(ya)縮(suo)空(kong)氣(qi)為(wei)10公斤，即為(wei)1MPa。如(ru)果沒有(you)安裝空(kong)氣(qi)過濾(lv)減(jian)壓(ya)閥(fa)進(jin)行(xing)調壓(ya)，對氣(qi)缸的損害程度(du)(du)大，而(er)且不(bu)利于開(kai)關速(su)度(du)(du)的控(kong)制(zhi)。通常情況，閥(fa)門(men)的工作(zuo)氣(qi)源(yuan)壓(ya)力在0.4MPa左右即可(ke)滿足閥(fa)門(men)的開(kai)關需求，因此(ci)從空(kong)壓(ya)站過來的壓(ya)縮(suo)空(kong)氣(qi)必須進(jin)行(xing)降(jiang)壓(ya)處理，調到適合閥(fa)門(men)動作(zuo)的氣(qi)壓(ya)，從而(er)更好的保護閥(fa)門(men)和開(kai)關速(su)度(du)(du)的控(kong)制(zhi)。

　　BURKERT電磁閥是一種(zhong)用(yong)于控制流體的自動化基礎元件，工(gong)業控制系統(tong)中被廣泛(fan)應用(yong)，有調整(zheng)流量、速度、介質的方(fang)

　　向等(deng)參數的(de)功能，BURKERT電磁(ci)閥具有(you)靈(ling)活性好、型號多、高精度、用途(tu)廣泛等(deng)特(te)點。不同種類的(de)電磁(ci)閥可在控(kong)制系統

　　的不(bu)同(tong)(tong)位置發揮不(bu)同(tong)(tong)的作用。電(dian)磁閥可分為多種。

　　在電(dian)磁(ci)(ci)閥的(de)(de)內部(bu)中有(you)封筆的(de)(de)腔(qiang)，腔(qiang)的(de)(de)兩面都(dou)分(fen)布(bu)了一(yi)塊(kuai)電(dian)磁(ci)(ci)鐵，腔(qiang)的(de)(de)中間就是(shi)活(huo)塞，一(yi)旦把電(dian)磁(ci)(ci)鐵里面的(de)(de)線(xian)圈通(tong)

　　電(dian)了之后(hou)，閥體便會(hui)有壓(ya)力就會(hui)被吸引至(zhi)通(tong)電(dian)電(dian)磁鐵的方向;腔的不同部位都開有通(tong)孔，連接著不同的油管，所以

　　便可以通過控制(zhi)電(dian)磁閥的移動(dong)來(lai)控制(zhi)開(kai)啟部分的排油孔;因為進油孔經常是打開(kai)狀態，閥體(ti)的移動(dong)可以改(gai)變(bian)液(ye)壓油
