1、稱重臺面的臺面值超差
*檢查機械稱重臺面引軌與計量軌軌縫距離是否正常、各過渡塊活動是否正常、限位拉桿松緊度是否合適。正常情況下，計量軌與引軌的間隙為5 - 15mm或過渡塊與計量軌的間隙為5mm，才能確定過渡塊活動自如。
* 測量每個稱重傳感器的輸入輸出電阻以及絕緣阻抗，發現西北角稱重傳感器信號線的供橋電源負端導線與外屏蔽導線之間電阻值異常，但一列火車駛過后此電阻值又恢復正常。檢查后確認西北角稱重傳感器信號線的供橋電源負端導線的外皮有破損，使信號線的供橋電源負端導線與外屏蔽導線之間處于似接非接狀態，造成故障時有時無。重新接線并做好各種防護后，臺面值恢復正常，計量稱重正常。
*測量(liang)各(ge)個稱(cheng)(cheng)(cheng)重傳感(gan)(gan)器(qi)的(de)輸入輸出電(dian)阻、絕緣阻抗(kang)以及零點(dian)輸出信(xin)號(hao)均正(zheng)常(chang)，但加(jia)載機車后分(fen)別測量(liang)各(ge)個稱(cheng)(cheng)(cheng)重傳感(gan)(gan)器(qi)輸出信(xin)號(hao)，發現西(xi)南角稱(cheng)(cheng)(cheng)重傳感(gan)(gan)器(qi)輸出信(xin)號(hao)的(de)變化量(liang)接(jie)(jie)近零而其它稱(cheng)(cheng)(cheng)重傳感(gan)(gan)器(qi)輸出信(xin)號(hao)的(de)變化量(liang)接(jie)(jie)近，判斷西(xi)南角稱(cheng)(cheng)(cheng)重傳感(gan)(gan)器(qi)損壞。更換(huan)西(xi)南角稱(cheng)(cheng)(cheng)重傳感(gan)(gan)器(qi)后臺值恢復正(zheng)常(chang)，計(ji)量(liang)稱(cheng)(cheng)(cheng)重正(zheng)常(chang)。

2 計量重車的稱重波形圖異常*計(ji)量重(zhong)車的正常稱重(zhong)波(bo)(bo)形如圖1所示。各波(bo)(bo)形分布相(xiang)對均勻且無任何尖峰和(he)(he)突起，若計(ji)量波(bo)(bo)形突然出現較多(duo)突起和(he)(he)尖峰，同一列火車的多(duo)次(ci)計(ji)量數(shu)據誤差(cha)高達±1.5t并且臺面值(zhi)發生以(yi)下變(bian)化：

*31t/4.12t、3.14t/4.12t、3.08t/4.11t、2.93t/4.13t、2.72t/4.12t（A秤臺值/B秤臺值），判斷A秤臺有故障。計量重車時觀察A秤臺與B秤臺機械稱重臺面，發現A秤臺西北角晃動特別大并且西北承重角的地腳螺栓松動、東南角稱重傳感器懸空。因此我們用機車壓住A秤臺后緊固所有地角螺栓并在東南角稱重傳感器下加5mm墊片，確保西北承重角的地腳螺栓不再松動且東南角稱重傳感器垂直受力。同一列火車重車多次計量后觀察A秤臺西北承重角震動正常并且計量數據誤差在±500kg內，計量波形也未出現突起和尖峰。
圖1 雙臺面重車的正常計量波形
*計(ji)量(liang)(liang)重車(che)的稱重波(bo)形出(chu)(chu)現(xian)不對稱狀態并且*節(jie)重車(che)計(ji)量(liang)(liang)數(shu)據偏(pian)小(xiao)(xiao)。計(ji)量(liang)(liang)重車(che)時(shi)發現(xian)機(ji)車(che)的*個(ge)車(che)輪后部(bu)伸出(chu)(chu)的擋片(pian)與計(ji)量(liang)(liang)軌距(ju)離不到10mm，造(zao)成(cheng)輪開關過(guo)早判斷開始(shi)計(ji)量(liang)(liang)重車(che)，從而導致*節(jie)重車(che)計(ji)量(liang)(liang)數(shu)據偏(pian)小(xiao)(xiao)。清理機(ji)車(che)*個(ge)車(che)輪擋片(pian)后稱重波(bo)形恢復正(zheng)常，計(ji)量(liang)(liang)數(shu)據也正(zheng)常。
