為減(jian)少系統故(gu)障(zhang)檢測(ce)的(de)(de)盲目性和(he)經驗性以(yi)(yi)及拆裝工作量(liang)，傳統的(de)(de)故(gu)障(zhang)診斷(duan)(duan)方法已(yi)遠(yuan)不能(neng)滿足現代液(ye)壓(ya)系統的(de)(de)要求。隨著液(ye)壓(ya)系統向大型化、連續生產、自動控制方向發(fa)展，又出(chu)(chu)(chu)現了多種現代故(gu)障(zhang)診斷(duan)(duan)方法。如鐵譜技斷(duan)(duan)，可(ke)從油液(ye)中分(fen)離(li)出(chu)(chu)(chu)來(lai)的(de)(de)各(ge)種磨(mo)(mo)粒的(de)(de)數量(liang)、形狀、尺寸、成分(fen)以(yi)(yi)及分(fen)布規律(lv)等(deng)情況(kuang)，及時、準確地(di)判斷(duan)(duan)出(chu)(chu)(chu)系統中元件的(de)(de)磨(mo)(mo)損部位、形式(shi)、程(cheng)度等(deng)。而且可(ke)對液(ye)壓(ya)油進行定量(liang)的(de)(de)污染分(fen)析和(he)評價，做(zuo)到在線檢測(ce)和(he)故(gu)障(zhang)預防。基于人工智能(neng)的(de)(de)診斷(duan)(duan)系斷(duan)(duan)，它通過計(ji)算機(ji)模仿在某一領域內有(you)(you)經驗 解決問題的(de)(de)方法。將(jiang)(jiang)故(gu)障(zhang)現象通過人機(ji)接(jie)口(kou)輸入(ru)(ru)計(ji)算機(ji)，計(ji)算機(ji)根據(ju)輸入(ru)(ru)的(de)(de)現象以(yi)(yi)及知識庫中的(de)(de)知識，可(ke)推算出(chu)(chu)(chu)引(yin)起故(gu)障(zhang)的(de)(de)原(yuan)因。如未(wei)作減(jian)速(su)處理，液(ye)壓(ya)缸活塞與(yu)缸蓋將(jiang)(jiang)發(fa)生機(ji)械碰撞(zhuang)，產生沖擊、噪聲，有(you)(you)破壞性。中國澳門(men)液(ye)壓(ya)油缸哪家好(hao)

1、應用(yong)傳統的(de)邏輯(ji)分析(xi)逐(zhu)(zhu)步(bu)逼近(jin)法。需(xu)對以上所有(you)可能原因(yin)逐(zhu)(zhu)一進行(xing)分析(xi)判斷(duan)(duan)和(he)檢驗(yan)， 終(zhong)找出(chu)故(gu)(gu)障(zhang)原因(yin)和(he)引起(qi)故(gu)(gu)障(zhang)的(de)具體元件(jian)。此法診斷(duan)(duan)過程繁瑣，須進行(xing)大(da)量的(de)裝拆(chai)、驗(yan)證工作(zuo)，效(xiao)率低，工期長(chang)，并(bing)且只能是定性(xing)(xing)分析(xi)，診斷(duan)(duan)不夠準確。2、應用(yong)基于參(can)數(shu)測(ce)量的(de)故(gu)(gu)障(zhang)診斷(duan)(duan)系統。只需(xu)在(zai)系統配管時，在(zai)泵的(de)出(chu)口a、換向閥前b及(ji)缸的(de)入口c三(san)點設置雙球(qiu)閥三(san)通，則利用(yong)故(gu)(gu)障(zhang)診斷(duan)(duan)檢測(ce)回路，在(zai)幾秒(miao)鐘內(nei)即可將系統故(gu)(gu)障(zhang)限制在(zai)某區域內(nei)并(bing)根(gen)據(ju)所測(ce)參(can)數(shu)值診斷(duan)(duan)出(chu)故(gu)(gu)障(zhang)所在(zai)。檢測(ce)過程如下：漳(zhang)州車輛液壓油(you)缸缸筒(tong)加工要求高(gao)，其內(nei)表面粗糙度(du)要求為Ra0.4～0.8&um，對同軸度(du)、耐磨性(xing)(xing)要求嚴(yan)格。

2、工作時(shi)不(bu)(bu)能驅動(dong)負載主要(yao)表現為活塞(sai)桿(gan)停位不(bu)(bu)準、推力不(bu)(bu)足(zu)、速度下降、工作不(bu)(bu)穩定等,其原(yuan)(yuan)因是(shi)(shi)：（1）液壓(ya)缸(gang)內部泄漏(lou)。液壓(ya)缸(gang)內部泄漏(lou)包括液壓(ya)缸(gang)體密(mi)(mi)封(feng)(feng)、活塞(sai)桿(gan)與密(mi)(mi)封(feng)(feng)蓋密(mi)(mi)封(feng)(feng)及(ji)(ji)活塞(sai)密(mi)(mi)封(feng)(feng)均磨損(sun)(sun)過量等引(yin)起(qi)的(de)(de)(de)泄漏(lou)。活塞(sai)桿(gan)與密(mi)(mi)封(feng)(feng)蓋密(mi)(mi)封(feng)(feng)泄漏(lou)的(de)(de)(de)原(yuan)(yuan)因是(shi)(shi)，密(mi)(mi)封(feng)(feng)件折皺、擠壓(ya)、撕裂(lie)、磨損(sun)(sun)、老(lao)化、變質、變形等，此(ci)時(shi)應(ying)更換(huan)新的(de)(de)(de)密(mi)(mi)封(feng)(feng)件。活塞(sai)密(mi)(mi)封(feng)(feng)過量磨損(sun)(sun)的(de)(de)(de)主要(yao)原(yuan)(yuan)因是(shi)(shi)速度控制閥(fa)調節不(bu)(bu)當(dang)(dang)，造成過高的(de)(de)(de)背壓(ya)以及(ji)(ji)密(mi)(mi)封(feng)(feng)件安裝(zhuang)不(bu)(bu)當(dang)(dang)或液壓(ya)油(you)污染。其次(ci)是(shi)(shi)裝(zhuang)配時(shi)有(you)異物進入(ru)及(ji)(ji)密(mi)(mi)封(feng)(feng)材(cai)料(liao)質量不(bu)(bu)好(hao)。其后果是(shi)(shi)動(dong)作緩(huan)慢、無力，嚴重(zhong)時(shi)還(huan)會造成活塞(sai)及(ji)(ji)缸(gang)筒的(de)(de)(de)損(sun)(sun)壞，出現“拉缸(gang)”現象。處(chu)理方法是(shi)(shi)調整速度控制閥(fa)，對照安裝(zhuang)說明應(ying)做(zuo)必要(yao)的(de)(de)(de)操作和改進。
