AB羅克韋爾伺服電機維修常見故障分析
1）、故障現象：電機不能啟動故障原因：停機按鈕鎖死,變頻器起運頻率太低,機械卡死,連鎖保護
解決措施：檢查控箱麵板停止按鈕，按鈕是否複位,zhongxinshedingbianpinqipinlv。yongshouzhuandongqizhangzhou，jianzhachuandongbufenshifouyoukazhixianxiang。yicijianzhagegongnengbujianyouwusunshihuopohuai，jianzhagebujiandegongzuozhuangtaishifouweiyukaijiyaoqiuweizhi。
故障原因：壓ya印yin膠jiao輥gun壓ya力li不bu合he適shi或huo兩liang端duan壓ya力li不bu均jun勻yun。薄bo膜mo入ru出chu料liao張zhang力li有you波bo動dong或huo張zhang力li過guo小xiao。薄bo膜mo卷juan料liao有you荷he葉ye邊bian，厚hou薄bo不bu均jun勻yun或huo膜mo間jian夾jia層ceng有you空kong氣qi。熱re風feng量liang太tai大da，薄bo膜mo過guo熱re後hou變bian形xing。版ban輥gun直zhi徑jing有you誤wu差cha或huo印yin刷shua版ban輥gun本ben身shen圖tu案an變bian形xing套tao印yin不bu準zhun。設she備bei長chang期qi使shi用yong未wei妥tuo善shan保bao養yang，不bu見jian損sun耗hao嚴yan重zhong，部bu件jian精jing度du損sun失shi。
解決措施：調tiao整zheng合he適shi的de壓ya力li或huo將jiang壓ya力li調tiao整zheng均jun勻yun。調tiao整zheng收shou放fang卷juan張zhang力li和he出chu入ru料liao牽qian引yin張zhang力li使shi得de張zhang力li均jun衡heng。換huan新xin料liao，刺ci破po薄bo膜mo間jian氣qi泡pao。調tiao整zheng合he適shi的de烘hong箱xiang溫wen度du和he風feng量liang。將jiang版ban輥gun誤wu差cha均jun勻yun分fen布bu，嚴yan重zhong時shi必bi須xu重zhong新xin製zhi版ban。更geng換huan磨mo損sun部bu件jian，檢jian修xiu設she備bei恢hui複fu設she備bei使shi用yong精jing度du。
故障原因：送料輥平行精度差。收卷或出料牽引張力不均勻熱風吹送不均勻印刷版輥和壓印膠輥壓力不均勻。
解決措施：調tiao整zheng各ge送song料liao輥gun相xiang對dui與yu版ban輥gun的de平ping行xing精jing度du直zhi至zhi滿man足zu要yao求qiu。調tiao整zheng出chu料liao牽qian引yin張zhang力li或huo收shou卷juan張zhang力li的de大da小xiao。調tiao整zheng熱re風feng風feng量liang的de大da小xiao，調tiao整zheng熱re風feng使shi其qi穩wen定ding並bing均jun勻yun吹chui送song。調tiao整zheng壓ya印yin膠jiao輥gun兩liang壓ya印yin氣qi缸gang節jie流liu閥fa使shi其qi膠jiao輥gun上shang升sheng下xia壓ya動dong作zuo同tong步bu，無wu幹gan涉she。
故障原因：熱風過大，油墨幹燥太快，油墨積墨在版輥表麵（幹版），壓ya印yin膠jiao輥gun和he印yin刷shua版ban輥gun壓ya印yin力li偏pian小xiao。刮gua刀dao和he版ban輥gun的de接jie觸chu角jiao度du不bu合he適shi或huo刮gua刀dao刮gua墨mo壓ya力li偏pian小xiao。油you墨mo中zhong溶rong劑ji量liang加jia入ru過guo多duo。印yin刷shua版ban輥gun和he圖tu文wen雕diao刻ke太tai淺qian，有you白bai點dian，毛mao刺ci。
解決措施：及(ji)時(shi)加(jia)入(ru)溶(rong)劑(ji)或(huo)更(geng)換(huan)溶(rong)劑(ji)類(lei)型(xing)，清(qing)洗(xi)版(ban)麵(mian)積(ji)墨(mo)。調(tiao)整(zheng)壓(ya)印(yin)膠(jiao)輥(gun)壓(ya)力(li)。調(tiao)整(zheng)刮(gua)刀(dao)和(he)版(ban)輥(gun)的(de)接(jie)觸(chu)角(jiao)度(du)及(ji)刮(gua)刀(dao)壓(ya)力(li)。適(shi)當(dang)加(jia)入(ru)原(yuan)墨(mo)並(bing)調(tiao)和(he)。重(zhong)新(xin)調(tiao)整(zheng)印(yin)刷(shua)版(ban)輥(gun)，清(qing)除(chu)版(ban)麵(mian)毛(mao)刺(ci)。
