C602控制儀表鋼瓶秤*洋浦無人值守地磅

1. 問(wen)題現象(xiang)：黑(hei)龍江某公司 120噸(dun)地磅有時(shi)(shi)重車開上(shang)后顯示負超載，重新開機后有時(shi)(shi)能(neng)(neng)恢(hui)復正常(chang)，此現象(xiang)經(jing)常(chang)發生。問(wen)題分析：問(wen)題時(shi)(shi)有時(shi)(shi)無，估計(ji)不是稱(cheng)重顯示器(qi)(qi)的原因。檢查磅臺(tai)、連接(jie)件、限位都(dou)正常(chang)，排(pai)除機械(xie)方面(mian)原因。把接(jie)線(xian)(xian)板上(shang)所有的焊點重新檢查一遍，排(pai)除了虛(xu)焊或脫焊的可能(neng)(neng)。后用(yong)“替代法”和“扯線(xian)(xian)法”查出(chu)故障(zhang)是由某個(ge)傳(chuan)感器(qi)(qi)引(yin)起的。經(jing)檢查確認有一個(ge)傳(chuan)感器(qi)(qi)的信號線(xian)(xian)被老(lao)鼠咬破，有時(shi)(shi)能(neng)(neng)接(jie)觸上(shang)，則儀(yi)表(biao)正常(chang)，有時(shi)(shi)則處(chu)(chu)于斷(duan)開狀(zhuang)態，儀(yi)表(biao)顯示負超載。問(wen)題處(chu)(chu)理(li)：把該傳(chuan)感器(qi)(qi)信號線(xian)(xian)從(cong)咬破皮處(chu)(chu)剪斷(duan)，用(yong)環(huan)氧樹脂處(chu)(chu)理(li)后，做個(ge)接(jie)頭，地磅恢(hui)復正常(chang)。

2. 問(wen)題(ti)(ti)現(xian)象(xiang)：山西(xi)某(mou)公(gong)司 120噸(dun)地磅(bang)(bang)顯(xian)示(shi)(shi)器顯(xian)示(shi)(shi)不(bu)穩，從＋ 20 到(dao) -100 跳變。問(wen)題(ti)(ti)分(fen)析：先(xian)用模(mo)擬器檢(jian)查(cha)證明儀表(biao)正常(chang)(chang)(chang)，經檢(jian)查(cha)也不(bu)是機械故(gu)(gu)障，則故(gu)(gu)障可能出(chu)在接(jie)(jie)(jie)線盒(he)或傳感器。該地磅(bang)(bang)有三節秤臺，三個(ge)接(jie)(jie)(jie)線盒(he)， 8 個(ge)傳感器，檢(jian)查(cha)時發現(xian)把(ba)北面(mian)秤臺通(tong)(tong)向中(zhong)(zhong)間(jian)接(jie)(jie)(jie)線盒(he)的(de)(de)信(xin)號總(zong)線焊下后，儀表(biao)顯(xian)示(shi)(shi)正常(chang)(chang)(chang)，而當(dang)把(ba)南(nan)面(mian)秤臺通(tong)(tong)向中(zhong)(zhong)間(jian)接(jie)(jie)(jie)線盒(he)的(de)(de)信(xin)號線焊下時，顯(xian)示(shi)(shi)器顯(xian)示(shi)(shi)依舊不(bu)穩，則得(de)出(chu)結論南(nan)面(mian)秤臺正常(chang)(chang)(chang)，問(wen)題(ti)(ti)由北面(mian)秤臺引(yin)起，包(bao)括四(si)個(ge)傳感器及兩個(ge)接(jie)(jie)(jie)線盒(he)。用萬用表(biao)測(ce)量(liang)，發現(xian)中(zhong)(zhong)間(jian)接(jie)(jie)(jie)線盒(he)內聯接(jie)(jie)(jie)北面(mian)秤臺的(de)(de)信(xin)號線中(zhong)(zhong)激勵電壓為 11 伏多且不(bu)穩，而正常(chang)(chang)(chang)值(zhi)為 12.5 伏，經檢(jian)查(cha)接(jie)(jie)(jie)線板上的(de)(de)＋ EX 接(jie)(jie)(jie)線孔(kong)虛焊。故(gu)(gu)障處理：焊一根短路線直(zhi)接(jie)(jie)(jie)把(ba)此＋ EX 接(jie)(jie)(jie)線端與儀表(biao)過來的(de)(de)＋ EX 端相連，故(gu)(gu)障解(jie)決(jue)。

1. 問(wen)題(ti)現象：黑(hei)龍江某(mou)公司 120噸地磅有(you)(you)(you)(you)時(shi)重車開(kai)(kai)上(shang)(shang)(shang)后顯(xian)示負(fu)超載，重新開(kai)(kai)機后有(you)(you)(you)(you)時(shi)能(neng)恢復正(zheng)常，此現象經常發(fa)生。問(wen)題(ti)分析：問(wen)題(ti)時(shi)有(you)(you)(you)(you)時(shi)無，估計不是(shi)稱重顯(xian)示器(qi)(qi)的(de)(de)(de)原因(yin)。檢(jian)查(cha)磅臺、連接(jie)件、限(xian)位(wei)都正(zheng)常，排(pai)除(chu)機械方(fang)面原因(yin)。把接(jie)線(xian)板上(shang)(shang)(shang)所有(you)(you)(you)(you)的(de)(de)(de)焊點重新檢(jian)查(cha)一遍(bian)，排(pai)除(chu)了虛(xu)焊或脫焊的(de)(de)(de)可能(neng)。后用“替代法”和“扯線(xian)法”查(cha)出故障是(shi)由某(mou)個傳感器(qi)(qi)引起的(de)(de)(de)。經檢(jian)查(cha)確認有(you)(you)(you)(you)一個傳感器(qi)(qi)的(de)(de)(de)信(xin)號線(xian)被老(lao)鼠咬(yao)破，有(you)(you)(you)(you)時(shi)能(neng)接(jie)觸上(shang)(shang)(shang)，則儀表正(zheng)常，有(you)(you)(you)(you)時(shi)則處(chu)(chu)于斷開(kai)(kai)狀(zhuang)態，儀表顯(xian)示負(fu)超載。問(wen)題(ti)處(chu)(chu)理(li)：把該傳感器(qi)(qi)信(xin)號線(xian)從(cong)咬(yao)破皮處(chu)(chu)剪(jian)斷，用環氧樹脂處(chu)(chu)理(li)后，做(zuo)個接(jie)頭，地磅恢復正(zheng)常。

2. 問題現象：山西某公司 120噸地磅顯(xian)(xian)示器顯(xian)(xian)示不(bu)(bu)穩(wen)，從＋ 20 到 -100 跳變。問題分析：先(xian)用模(mo)擬器檢查證(zheng)明儀(yi)(yi)表(biao)正常，經(jing)檢查也(ye)不(bu)(bu)是(shi)機(ji)械故障，則(ze)故障可能出在接(jie)(jie)線(xian)(xian)(xian)盒(he)或傳(chuan)感器。該地磅有三(san)節秤(cheng)(cheng)臺(tai)(tai)，三(san)個(ge)(ge)(ge)接(jie)(jie)線(xian)(xian)(xian)盒(he)， 8 個(ge)(ge)(ge)傳(chuan)感器，檢查時發現把北(bei)面秤(cheng)(cheng)臺(tai)(tai)通(tong)向中間接(jie)(jie)線(xian)(xian)(xian)盒(he)的(de)信(xin)號總線(xian)(xian)(xian)焊下后，儀(yi)(yi)表(biao)顯(xian)(xian)示正常，而(er)當把南面秤(cheng)(cheng)臺(tai)(tai)通(tong)向中間接(jie)(jie)線(xian)(xian)(xian)盒(he)的(de)信(xin)號線(xian)(xian)(xian)焊下時，顯(xian)(xian)示器顯(xian)(xian)示依(yi)舊不(bu)(bu)穩(wen)，則(ze)得(de)出結論(lun)南面秤(cheng)(cheng)臺(tai)(tai)正常，問題由北(bei)面秤(cheng)(cheng)臺(tai)(tai)引起，包括四個(ge)(ge)(ge)傳(chuan)感器及(ji)兩(liang)個(ge)(ge)(ge)接(jie)(jie)線(xian)(xian)(xian)盒(he)。用萬用表(biao)測量，發現中間接(jie)(jie)線(xian)(xian)(xian)盒(he)內聯接(jie)(jie)北(bei)面秤(cheng)(cheng)臺(tai)(tai)的(de)信(xin)號線(xian)(xian)(xian)中激(ji)勵電(dian)壓為(wei) 11 伏多且不(bu)(bu)穩(wen)，而(er)正常值為(wei) 12.5 伏，經(jing)檢查接(jie)(jie)線(xian)(xian)(xian)板(ban)上(shang)的(de)＋ EX 接(jie)(jie)線(xian)(xian)(xian)孔虛焊。故障處理：焊一根短路線(xian)(xian)(xian)直接(jie)(jie)把此＋ EX 接(jie)(jie)線(xian)(xian)(xian)端與(yu)儀(yi)(yi)表(biao)過(guo)來的(de)＋ EX 端相連，故障解決。
