美(mei)國Ross電磁(ci)閥在加(jia)油(you)定量(liang)時失(shi)效的原(yuan)因及維修方法,

    Ross電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)翻轉。當加(jia)(jia)(jia)(jia)油(you)(you)(you)量保持在0.3升(sheng)至0.5升(sheng)時(shi)(shi)(shi),計(ji)算機宣布關(guan)閉大流量信號(hao),小流量繼(ji)續加(jia)(jia)(jia)(jia)油(you)(you)(you)至預(yu)設值,最后關(guan)閉小流量,關(guan)閉電(dian)(dian)(dian)(dian)(dian)(dian)機,使其不(bu)(bu)(bu)會(hui)出現(xian)(xian)超額支(zhi)付的(de)(de)(de)現(xian)(xian)象。當羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)內的(de)(de)(de)隔膜(mo)被拆下或轉過來,加(jia)(jia)(jia)(jia)油(you)(you)(you)次(ci)數達(da)到(dao)預(yu)設值時(shi)(shi)(shi),主(zhu)板(ban)(ban)發出的(de)(de)(de)信號(hao)不(bu)(bu)(bu)能(neng)(neng)關(guan)閉油(you)(you)(you)路(lu)(lu),繼(ji)續大流量加(jia)(jia)(jia)(jia)油(you)(you)(you),使顯示板(ban)(ban)的(de)(de)(de)數目大于預(yu)設的(de)(de)(de)加(jia)(jia)(jia)(jia)油(you)(you)(you)次(ci)數。加(jia)(jia)(jia)(jia)油(you)(you)(you)時(shi)(shi)(shi),有(you)時(shi)(shi)(shi)會(hui)遇到(dao)加(jia)(jia)(jia)(jia)油(you)(you)(you)機出油(you)(you)(you)慢或無(wu)(wu)油(you)(you)(you)的(de)(de)(de)情(qing)(qing)況。造成這種(zhong)情(qing)(qing)況的(de)(de)(de)原(yuan)因(yin)(yin)有(you)很多(duo),其中一(yi)些是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)損壞造成的(de)(de)(de)。維修時(shi)(shi)(shi),為(wei)了節約能(neng)(neng)源,拆卸或重新安裝羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)內的(de)(de)(de)隔膜(mo),使羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)能(neng)(neng)夠(gou)接通。有(you)些人認為(wei)它(ta)(ta)會(hui)用這種(zhong)方(fang)法(fa)修理。這確實會(hui)導致油(you)(you)(you)輪漏油(you)(you)(you),但(dan)(dan)它(ta)(ta)留(liu)下了一(yi)個(ge)“災難性"的(de)(de)(de)結(jie)果(guo)——不(bu)(bu)(bu)進行定量加(jia)(jia)(jia)(jia)油(you)(you)(you),也不(bu)(bu)(bu)計(ji)算加(jia)(jia)(jia)(jia)油(you)(you)(you)次(ci)數。當雙槍(qiang)機出現(xian)(xian)上述情(qing)(qing)況時(shi)(shi)(shi),一(yi)支(zhi)槍(qiang)正常加(jia)(jia)(jia)(jia)油(you)(you)(you),另(ling)一(yi)支(zhi)槍(qiang)因(yin)(yin)羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)斷開(kai)而不(bu)(bu)(bu)能(neng)(neng)關(guan)閉油(you)(you)(you)路(lu)(lu),也能(neng)(neng)在不(bu)(bu)(bu)啟動(dong)的(de)(de)(de)情(qing)(qing)況下產生油(you)(you)(you),但(dan)(dan)由于主(zhu)板(ban)(ban)沒有(you)收到(dao)啟動(dong)信號(hao),所以(yi)無(wu)(wu)法(fa)計(ji)數,必然存在危險。因(yin)(yin)此,當羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)不(bu)(bu)(bu)能(neng)(neng)打開(kai)而導致加(jia)(jia)(jia)(jia)油(you)(you)(you)機缺(que)油(you)(you)(you)時(shi)(shi)(shi),應正確修理。首(shou)先要檢(jian)查(cha)羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)的(de)(de)(de)控制電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu),如零線是(shi)(shi)(shi)否入位,燈閥(fa)(fa)(fa)(fa)(fa)板(ban)(ban)是(shi)(shi)(shi)否損壞等(deng);其次(ci),檢(jian)查(cha)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)本身,如閥(fa)(fa)(fa)(fa)(fa)內線圈是(shi)(shi)(shi)否打開(kai),閥(fa)(fa)(fa)(fa)(fa)膜(mo)孔(kong)是(shi)(shi)(shi)否堵(du)塞等(deng);如果(guo)羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)本身有(you)缺(que)陷,以(yi)及無(wu)(wu)法(fa)糾(jiu)正,應更換新的(de)(de)(de)羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)。另(ling)外,在購買(mai)羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)時(shi)(shi)(shi),應注(zhu)意(yi)用普通型替換。美國羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)故障的(de)(de)(de)原(yuan)因(yin)(yin)及維修方(fang)法(fa)將直接影響切(qie)換閥(fa)(fa)(fa)(fa)(fa)和調節閥(fa)(fa)(fa)(fa)(fa)的(de)(de)(de)動(dong)作。常見故障包括羅(luo)(luo)(luo)(luo)斯(si)(si)(si)(si)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)不(bu)(bu)(bu)動(dong)作,應從(cong)以(yi)下幾個(ge)方(fang)面進行檢(jian)查(cha):

     (1)羅斯電(dian)磁閥連(lian)接頭(tou)松動或線頭(tou)脫落,羅斯電(dian)磁閥未通電(dian),線頭(tou)可以擰緊。       

     (2)羅斯電磁(ci)閥(fa)線(xian)(xian)(xian)圈(quan)(quan)(quan)燒壞(huai)。可以拆下電磁(ci)閥(fa)的導(dao)線(xian)(xian)(xian)并用萬用表測量(liang)。如果電路開(kai)路,羅斯電磁(ci)閥(fa)線(xian)(xian)(xian)圈(quan)(quan)(quan)將(jiang)燒壞(huai)。原因(yin)是線(xian)(xian)(xian)圈(quan)(quan)(quan)受潮,絕緣不(bu)良,漏磁(ci),線(xian)(xian)(xian)圈(quan)(quan)(quan)電流過大(da),燒壞(huai),必須防止雨水進入電磁(ci)閥(fa)。另外,彈簧太硬,反作用力太大(da),線(xian)(xian)(xian)圈(quan)(quan)(quan)匝數太少,吸(xi)力不(bu)夠也會(hui)使(shi)線(xian)(xian)(xian)圈(quan)(quan)(quan)燒壞(huai)。在處(chu)理緊急情況時,線(xian)(xian)(xian)圈(quan)(quan)(quan)上的手(shou)動按(an)鈕(niu)可以在正常操作時從(cong)0“位推(tui)到1"位,使(shi)閥(fa)門打(da)開(kai)。

    (3)羅斯電磁(ci)閥(fa)(fa)(fa)(fa)卡住。羅斯電磁(ci)閥(fa)(fa)(fa)(fa)滑(hua)套(tao)與閥(fa)(fa)(fa)(fa)芯配(pei)合間隙很小(小于0.008mm)。它(ta)通常(chang)組裝成一(yi)個整(zheng)體(ti)。當有(you)機(ji)械雜質(zhi)或潤滑(hua)油(you)太少時,容易堵(du)塞。這(zhe)種(zhong)處理(li)方法可(ke)以用鋼絲刺(ci)入頭部(bu)的小孔(kong),使其反(fan)彈。根本(ben)的解(jie)決辦(ban)法是(shi)(shi)(shi)拆(chai)(chai)下電磁(ci)閥(fa)(fa)(fa)(fa),拆(chai)(chai)下閥(fa)(fa)(fa)(fa)芯和閥(fa)(fa)(fa)(fa)芯套(tao),用CCI4清洗使之(zhi)成為閥(fa)(fa)(fa)(fa)。閥(fa)(fa)(fa)(fa)芯在閥(fa)(fa)(fa)(fa)套(tao)中運動靈活(huo)。拆(chai)(chai)卸時,應注意每個部(bu)件的裝配(pei)順序和外部(bu)接線位置,以便正確(que)地(di)重新裝配(pei)和接線,檢查噴油(you)孔(kong)是(shi)(shi)(shi)否堵(du)塞以及潤滑(hua)油(you)是(shi)(shi)(shi)否足夠。

    (4)泄漏。泄漏會導致氣壓不足,使強制閥(fa)的(de)開(kai)啟和關(guan)閉困難。原因是密(mi)封墊損壞或(huo)滑動閥(fa)磨(mo)損,導致多個(ge)空腔竄槽。在(zai)處理切換系(xi)統中電(dian)磁閥(fa)的(de)故障時,應選擇(ze)適當的(de)時間(jian)在(zai)電(dian)磁閥(fa)斷(duan)電(dian)時進行處理。如果在(zai)一個(ge)開(kai)關(guan)間(jian)隙(xi)內沒(mei)有完成該(gai)過(guo)程,則可以(yi)暫停并平靜地處理開(kai)關(guan)系(xi)統
