SMC電磁閥的(de)(de)(de)故障(zhang)將(jiang)直接影響到切(qie)換閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)和調節閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)的(de)(de)(de)動(dong)(dong)作,常見(jian)的(de)(de)(de)故障(zhang)有電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)不動(dong)(dong)作,應(ying)從以(yi)下(xia)(xia)幾方面排查:SMC電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)接線(xian)(xian)(xian)(xian)頭松動(dong)(dong)或線(xian)(xian)(xian)(xian)頭脫落(luo),電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)不得(de)(de)電(dian)(dian)(dian),可緊固(gu)線(xian)(xian)(xian)(xian)頭。線(xian)(xian)(xian)(xian)圈(quan)(quan)燒(shao)壞(huai),可拆下(xia)(xia)電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)的(de)(de)(de)接線(xian)(xian)(xian)(xian),用萬用表測量(liang),如(ru)果開路,則電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)線(xian)(xian)(xian)(xian)圈(quan)(quan)燒(shao)壞(huai)。原(yuan)因有線(xian)(xian)(xian)(xian)圈(quan)(quan)受潮,引起絕緣(yuan)不好而漏磁(ci),造成(cheng)線(xian)(xian)(xian)(xian)圈(quan)(quan)內(nei)電(dian)(dian)(dian)流過大而燒(shao)毀,因此(ci)要(yao)防止(zhi)雨(yu)水(shui)進(jin)入電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)。此(ci)外,彈(dan)簧過硬,反作用力過大,線(xian)(xian)(xian)(xian)圈(quan)(quan)匝數太(tai)(tai)少,吸(xi)力不夠也可使得(de)(de)線(xian)(xian)(xian)(xian)圈(quan)(quan)燒(shao)毀。緊急(ji)處(chu)(chu)理(li)時,可將(jiang)線(xian)(xian)(xian)(xian)圈(quan)(quan)上(shang)的(de)(de)(de)手動(dong)(dong)按鈕由正(zheng)常工(gong)作時的(de)(de)(de)“0”位(wei)打(da)到“1”位(wei),使得(de)(de)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)打(da)開。SMC電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)卡(ka)住。電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)的(de)(de)(de)滑(hua)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)套(tao)與閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)芯(xin)(xin)的(de)(de)(de)配(pei)(pei)合間隙很小(小于0.008mm),一般(ban)都是(shi)單(dan)件(jian)裝(zhuang)配(pei)(pei),當有機械雜(za)質帶入或潤(run)滑(hua)油太(tai)(tai)少時,很容(rong)(rong)易卡(ka)住。處(chu)(chu)理(li)方法(fa)可用鋼絲從頭部小孔捅入,使其彈(dan)回。根本的(de)(de)(de)解(jie)決方法(fa)是(shi)要(yao)將(jiang)電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)拆下(xia)(xia),取出閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)芯(xin)(xin)及閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)芯(xin)(xin)套(tao),用CCI4清洗,使得(de)(de)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)芯(xin)(xin)在(zai)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)套(tao)內(nei)動(dong)(dong)作靈活。拆卸時應(ying)注意各部件(jian)的(de)(de)(de)裝(zhuang)配(pei)(pei)順序(xu)及外部接線(xian)(xian)(xian)(xian)位(wei)置,以(yi)便重新裝(zhuang)配(pei)(pei)及接線(xian)(xian)(xian)(xian)正(zheng)確(que),還要(yao)檢查油霧(wu)器噴油孔是(shi)否堵(du)塞,潤(run)滑(hua)油是(shi)否足(zu)夠。漏氣。漏氣會造成(cheng)空(kong)氣壓力不足(zu),使得(de)(de)強(qiang)制閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)的(de)(de)(de)啟閉困難,原(yuan)因是(shi)密(mi)封墊片損(sun)壞(huai)或滑(hua)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)磨損(sun)而造成(cheng)幾個空(kong)腔竄氣。在(zai)處(chu)(chu)理(li)切(qie)換系統的(de)(de)(de)電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)故障(zhang)時,應(ying)選擇(ze)適(shi)當的(de)(de)(de)時機, 等(deng)該(gai)電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)處(chu)(chu)于失(shi)電(dian)(dian)(dian)時進(jin)行處(chu)(chu)理(li),若(ruo)在(zai)一個切(qie)換間隙內(nei)處(chu)(chu)理(li)不完,可將(jiang)切(qie)換系統暫停,從容(rong)(rong)處(chu)(chu)理(li)。
日本SMC電(dian)磁閥SY7120系列
SMC電磁閥:用(yong)于液(ye)體和氣體管路的開關控(kong)(kong)(kong)制(zhi),是兩位DO控(kong)(kong)(kong)制(zhi)。一般用(yong)于小型管道的控(kong)(kong)(kong)制(zhi)。
SMC電磁閥:只能(neng)用作開關量(liang),是DO控制,只能(neng)用于小管(guan)道(dao)控制,常見于DN50及以(yi)下管(guan)道(dao),往上(shang)就很少了(le)。
