一(yi).汽車衡各稱重(zhong)段(duan)誤差(cha)大(即(ji)點差(cha)大)如(ru)何處理。(以(yi)一(yi)煉(lian)鋼汽車衡為例)

故障現象：一臺(tai)(tai)重車(80噸左(zuo)右(you))在秤(cheng)臺(tai)(tai)停車位置(zhi)不同，稱量的數值不同。

分析處理：

1．從故(gu)障現象可分析出該(gai)秤(cheng)各承重點(dian)(dian)(dian)(共8點(dian)(dian)(dian))誤差(cha)大，測(ce)試各傳(chuan)感器(qi)(qi)的(de)激勵電壓(ya)及(ji)輸出信號，與原始記錄進行比較，發(fa)現西(xi)北(bei)中傳(chuan)感器(qi)(qi)激勵電壓(ya)變化(hua)大，檢查該(gai)接(jie)線(xian)端子(在接(jie)線(xian)盒處)發(fa)現一個微(wei)調(diao)電阻有問題(ti)，可以認為(wei)該(gai)接(jie)線(xian)盒有問題(ti)。更(geng)換該(gai)接(jie)線(xian)盒，用砝碼壓(ya)點(dian)(dian)(dian)(8點(dian)(dian)(dian))，用標準檢衡車標定。

2．檢查秤體(ti)、限位裝置(zhi)、接(jie)線(xian)盒、傳(chuan)感器受(shou)力狀(zhuang)態、各插(cha)頭、信息(xi)線(xian)均無問題后，用砝(fa)碼壓點(dian)(8點(dian))，用標準檢衡車標定(ding)(ding)，或用滿(man)量程砝(fa)碼標定(ding)(ding)。

說明(ming)：對于點差大的(de)處(chu)理，一定要認真仔細的(de)檢查各個(ge)部件，測試(shi)傳感器(qi)的(de)輸入(ru)輸出(chu)電壓，在(zai)確認故障原因后(hou)，方可采(cai)用用砝碼壓點的(de)方法。

二.汽(qi)(qi)車衡(平(ping)臺秤)稱重儀表不顯示(shi)空秤零(ling)點，只顯示(shi)光標如何(he)處理(li)。(以大無縫汽(qi)(qi)車衡為例)

故(gu)障(zhang)現象：稱重(zhong)儀表不顯示空秤零(ling)點，只(zhi)顯示光標。

分(fen)析處理：在8142型稱(cheng)重儀(yi)表(biao)(biao)表(biao)(biao)后九針插頭(tou)處測(ce)試儀(yi)表(biao)(biao)輸出激勵電壓正常(12.5V)輸入信號不穩定；

檢查(cha)儀(yi)表接(jie)地及信息線的(de)屏(ping)蔽、絕緣(yuan)良好；在接(jie)線盒處測(ce)輸出信號(hao)仍不穩(wen)定(ding)(ding)，逐(zhu)一拆下各傳感(gan)器(qi)(qi)信號(hao)線并(bing)測(ce)試，發現北中(zhong)點傳感(gan)器(qi)(qi)輸出信號(hao)不穩(wen)定(ding)(ding)，拆下此傳感(gan)器(qi)(qi)所(suo)有連線，接(jie)通儀(yi)表電(dian)源，儀(yi)表清(qing)零后，顯示示值(zhi)為零，且穩(wen)定(ding)(ding)；由此可(ke)判(pan)斷出此傳感(gan)器(qi)(qi)(測(ce)阻值(zhi)異常)有問(wen)題，更換該傳感(gan)并(bing)校秤，故障排(pai)除(chu)。

說(shuo)明：詢問當班計量員，得(de)知現(xian)場吊裝鋼(gang)坯脫落，落點(dian)在該傳(chuan)感器(qi)正上方。

三.汽車衡稱(cheng)重(zhong)儀表零點偶爾(er)上漂(piao)移(yi)。(以一煉(lian)鋼汽車衡為例)

故(gu)障現象：儀(yi)表顯示不(bu)正(zheng)常，零點(dian)上漂zui多達8噸(dun)，有(you)時(shi)穩定不(bu)變，故(gu)障持續(xu)時(shi)間短，突(tu)發性大，有(you)時(shi)幾天，有(you)時(shi)幾小(xiao)時(shi)出現一次(ci)。
