橫涇便攜式地磅*渡村稱重模塊*橫塘汽車衡檢修流程：

檢(jian)查(cha)信號(hao)線(xian)是否(fou)(fou)斷裂(lie)，主(zhu)(zhu)線(xian)與儀(yi)表(biao)接(jie)頭焊點是否(fou)(fou)脫落 ，接(jie)線(xian)盒(he)里面里接(jie)線(xian)是否(fou)(fou)良(liang)好等等，這些都可能導致(zhi)這個癥狀(zhuang)的(de)發生。有(you)些秤(cheng)體至儀(yi)表(biao)之間距(ju)離過大，其(qi)間主(zhu)(zhu)線(xian)有(you)外露(lu)部(bu)分，有(you)可能被人(ren)為破壞或老鼠啃咬(yao)，金屬屏蔽失去作(zuo)用(yong)(yong)或連(lian)接(jie)處不牢，造成數字跳(tiao)變(bian)。用(yong)(yong)萬用(yong)(yong)表(biao)電(dian)阻檔測量(liang)該(gai)主(zhu)(zhu)線(xian)，以確保每一股都是獨的(de)通(tong)道(dao)，并(bing)且連(lian)線(xian)牢固(gu)，否(fou)(fou)則更換主(zhu)(zhu)線(xian)。其(qi)重點是，一定要(yao)仔細(xi)確認接(jie)線(xian)是否(fou)(fou)有(you)問題。如若接(jie)線(xian)是好的(de)，那么再請檢(jian)查(cha)儀(yi)表(biao)是否(fou)(fou)正(zheng)(zheng)常，必要(yao)時可開封檢(jian)查(cha)儀(yi)表(biao)內部(bu)連(lian)接(jie)線(xian)是否(fou)(fou)正(zheng)(zheng)常。

檢查接(jie)(jie)線盒內(nei)電(dian)路(lu)板(ban)(ban)是否損壞。接(jie)(jie)線盒內(nei)的電(dian)路(lu)板(ban)(ban)是由接(jie)(jie)線端子(zi)盒和幾組(zu)多(duo)圈電(dian)阻(zu)(zu)(zu)組(zu)成(cheng)。接(jie)(jie)線端子(zi)長期(qi)使(shi)用可(ke)(ke)致(zhi)氧(yang)化銹蝕(shi)，接(jie)(jie)頭處(chu)氧(yang)化銹蝕(shi)部(bu)(bu)分(fen)脫落，導(dao)致(zhi)壓線松動(dong)，從而(er)使(shi)儀(yi)表數(shu)字(zi)跳(tiao)變。此(ci)時，可(ke)(ke)用砂紙或銼(cuo)刀摩擦掉其接(jie)(jie)觸面(mian)(mian)，重(zhong)新連(lian)接(jie)(jie)牢固，故障現象排除。多(duo)圈電(dian)阻(zu)(zu)(zu)長期(qi)使(shi)用也(ye)可(ke)(ke)導(dao)致(zhi)內(nei)部(bu)(bu)金屬表面(mian)(mian)被(bei)氧(yang)化，使(shi)得(de)數(shu)字(zi)不穩、跳(tiao)變，此(ci)時用更換相同阻(zu)(zu)(zu)值的多(duo)圈電(dian)阻(zu)(zu)(zu)即可(ke)(ke)排除故障

汽車衡常(chang)見問(wen)題及(ji)(ji)處(chu)理(li)汽車衡維修(xiu)的(de)(de)(de)(de)過(guo)(guo)程中(zhong)會出(chu)現(xian)(xian)跳(tiao)(tiao)數(shu)(shu)的(de)(de)(de)(de)現(xian)(xian)象(xiang)，在這里淺談一(yi)(yi)下(xia)(xia)(xia)自己所(suo)遇到的(de)(de)(de)(de)幾種跳(tiao)(tiao)數(shu)(shu)現(xian)(xian)象(xiang)及(ji)(ji)解決辦法。  1.電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)(ya)(ya)不穩。汽車衡儀(yi)表(biao)的(de)(de)(de)(de)輸入電(dian)(dian)(dian)壓(ya)(ya)(ya)范圍(wei)為(187～242)V，某些使用單(dan)位未加穩壓(ya)(ya)(ya)電(dian)(dian)(dian)源，造成(cheng)(cheng)超出(chu)儀(yi)表(biao)的(de)(de)(de)(de)正(zheng)常(chang)工作電(dian)(dian)(dian)壓(ya)(ya)(ya)范圍(wei)，出(chu)現(xian)(xian)數(shu)(shu)字跳(tiao)(tiao)變現(xian)(xian)象(xiang)，配置(zhi)一(yi)(yi)個穩壓(ya)(ya)(ya)電(dian)(dian)(dian)源。  2. 接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)盒(he)密封不好(hao)，盒(he)內(nei)濕度過(guo)(guo)大。打開接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)盒(he)觀(guan)察是(shi)否(fou)有(you)水(shui)珠(zhu)或(huo)(huo)潮氣，通(tong)過(guo)(guo)晾曬(shai)或(huo)(huo)用吹(chui)風機吹(chui)干(gan)，故(gu)障即可(ke)排除。必要時(shi)(shi)更(geng)換接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)盒(he)。  3. 主(zhu)線(xian)(xian)(xian)(xian)(xian)損壞(huai)(huai)。有(you)些秤體至儀(yi)表(biao)之間(jian)距離過(guo)(guo)大，其間(jian)主(zhu)線(xian)(xian)(xian)(xian)(xian)有(you)外露部分，有(you)可(ke)能被(bei)(bei)人為破壞(huai)(huai)或(huo)(huo)老鼠啃咬(yao)，金屬(shu)屏蔽(bi)失去作用或(huo)(huo)連(lian)接(jie)(jie)(jie)處(chu)不牢(lao)，造成(cheng)(cheng)數(shu)(shu)字跳(tiao)(tiao)變。用萬(wan)用表(biao)電(dian)(dian)(dian)阻檔測量該(gai)主(zhu)線(xian)(xian)(xian)(xian)(xian)，以確保(bao)每一(yi)(yi)股(gu)都是(shi)獨(du)立的(de)(de)(de)(de)通(tong)道，并且連(lian)線(xian)(xian)(xian)(xian)(xian)牢(lao)固(gu)，否(fou)則更(geng)換主(zhu)線(xian)(xian)(xian)(xian)(xian)。  4. 接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)盒(he)內(nei)電(dian)(dian)(dian)路板(ban)損壞(huai)(huai)。接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)盒(he)內(nei)的(de)(de)(de)(de)電(dian)(dian)(dian)路板(ban)是(shi)由接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)端子(zi)盒(he)和電(dian)(dian)(dian)位器組成(cheng)(cheng)。接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)端子(zi)長期(qi)使用可(ke)致氧化銹蝕，接(jie)(jie)(jie)頭處(chu)氧化銹蝕部分脫落，導(dao)致壓(ya)(ya)(ya)線(xian)(xian)(xian)(xian)(xian)松動，從而使儀(yi)表(biao)數(shu)(shu)字跳(tiao)(tiao)變。此時(shi)(shi)，可(ke)用砂紙(zhi)或(huo)(huo)銼刀摩擦掉(diao)其接(jie)(jie)(jie)觸面(mian)，重新連(lian)接(jie)(jie)(jie)牢(lao)固(gu)，故(gu)障現(xian)(xian)象(xiang)排除。電(dian)(dian)(dian)位器長期(qi)使用也可(ke)導(dao)致內(nei)部金屬(shu)表(biao)面(mian)被(bei)(bei)氧化，使得數(shu)(shu)字不穩、跳(tiao)(tiao)變，此時(shi)(shi)用更(geng)換相同(tong)阻值的(de)(de)(de)(de)電(dian)(dian)(dian)位器即可(ke)排除故(gu)障。  5. 強電(dian)(dian)(dian)干(gan)擾(rao)。當汽車衡附(fu)近有(you)強電(dian)(dian)(dian)操作時(shi)(shi)會干(gan)擾(rao)到汽車衡的(de)(de)(de)(de)正(zheng)常(chang)工作，引起跳(tiao)(tiao)數(shu)(shu)是(shi)其中(zhong)的(de)(de)(de)(de)一(yi)(yi)個表(biao)現(xian)(xian)形式，此時(shi)(shi)要停止強電(dian)(dian)(dian)操作。做好(hao)接(jie)(jie)(jie)地線(xian)(xian)(xian)(xian)(xian)進行(xing)抗干(gan)擾(rao)。  6. 傳感(gan)器損壞(huai)(huai)、漂移。當傳感(gan)器損壞(huai)(huai)或(huo)(huo)發生(sheng)漂移時(shi)(shi)，也可(ke)造成(cheng)(cheng)數(shu)(shu)字跳(tiao)(tiao)變不穩。一(yi)(yi)般情況下(xia)(xia)(xia)，有(you)一(yi)(yi)只(zhi)傳感(gan)器漂移或(huo)(huo)損壞(huai)(huai)。判(pan)斷具(ju)體哪只(zhi)有(you)故(gu)障，可(ke)用直(zhi)接(jie)(jie)(jie)連(lian)接(jie)(jie)(jie)主(zhu)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)方法進行(xing)。即把所(suo)有(you)傳感(gan)器接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)(xian)逐只(zhi)拆下(xia)(xia)(xia)直(zhi)至剩(sheng)下(xia)(xia)(xia)一(yi)(yi)只(zhi)，然后(hou)把傳感(gan)器逐只(zhi)接(jie)(jie)(jie)上，同(tong)時(shi)(shi)觀(guan)察儀(yi)表(biao)顯示是(shi)否(fou)正(zheng)常(chang)，即可(ke)判(pan)斷出(chu)損壞(huai)(huai)的(de)(de)(de)(de)傳感(gan)器。予以更(geng)換即可(ke)解決問(wen)題。
