下麵我們從組成設備的三部分來了解一下診斷自動化設備故障的方法。
1． 檢查自動化設備的所有電源，氣源，液壓源
電dian源yuan，氣qi源yuan和he液ye壓ya源yuan的de問wen題ti會hui經jing常chang導dao致zhi自zi動dong化hua設she備bei出chu現xian故gu障zhang。比bi如ru供gong電dian出chu現xian問wen題ti，包bao括kuo整zheng個ge車che間jian供gong電dian的de故gu障zhang，比bi如ru電dian源yuan功gong率lv低di，保bao險xian燒shao毀hui，電dian源yuan插cha頭tou接jie觸chu不bu良liang等deng；qibenghuoyeyabengweikaiqi，qidongsanlianjianhuoerlianjianweikaiqi，yeyaxitongzhongdexiehefahuomouxieyalifaweikaiqideng。jiancezidonghuashebeishiyingbaokuoyixiajigefangmian：a、電源，包括每台設備的供電電源和車間的動力電。b、氣源，包括氣動裝置所需的氣壓源。c、液壓源，包括自動化設備液壓裝置需要的液壓泵的工作情況。
2． 檢查自動化設備的傳感器位置是否出現偏移
由you於yu設she備bei維wei護hu人ren員yuan的de疏shu忽hu，可ke能neng某mou些xie傳chuan感gan器qi的de位wei置zhi出chu現xian差cha錯cuo，比bi如ru沒mei有you到dao位wei，傳chuan感gan器qi故gu障zhang，靈ling敏min度du故gu障zhang等deng。要yao經jing常chang檢jian查zha傳chuan感gan器qi的de傳chuan感gan位wei置zhi和he靈ling敏min度du，出chu現xian偏pian差cha及ji時shi調tiao節jie，傳chuan感gan器qi如ru果guo壞huai掉diao，立li刻ke更geng換huan。很hen多duo時shi候hou，此ci外wai，由you於yu自zi動dong化hua設she備bei的de震zhen動dong，大da部bu分fen的de傳chuan感gan器qi在zai長chang期qi使shi用yong後hou，都dou會hui出chu現xian位wei置zhi鬆song動dong的de情qing況kuang，所suo以yi在zai日ri常chang維wei護hu時shi要yao經jing常chang檢jian查zha傳chuan感gan器qi的de位wei置zhi是shi否fou正zheng確que，是shi否fou固gu定ding牢lao固gu。
3． 檢查自動化設備的繼電器，流量控製閥，壓力控製閥

4． 檢查電氣，氣動和液壓回路連接
如ru果guo以yi上shang三san步bu都dou沒mei有you發fa現xian任ren何he問wen題ti，那na麼me檢jian查zha所suo有you回hui路lu。查zha看kan電dian路lu中zhong的de導dao線xian是shi否fou出chu現xian斷duan路lu，尤you其qi是shi線xian槽cao內nei的de導dao線xian是shi否fou由you於yu拉la扯che被bei線xian槽cao剮gua斷duan。檢jian查zha氣qi管guan是shi否fou有you損sun壞huai性xing的de折zhe痕hen。檢jian查zha液ye壓ya油you管guan是shi否fou堵du塞sai。如ru果guo氣qi管guan出chu現xian嚴yan重zhong折zhe痕hen，立li刻ke更geng換huan。液ye壓ya油you管guan一yi樣yang要yao更geng換huan。
