（4）故障診斷是建立在運(yùn)行記錄及某些系統(tǒng)參數(shù)基礎(chǔ)之上的。建立系統(tǒng)運(yùn)行記錄，這是預(yù)防、發(fā)現(xiàn)和處理故障的科學(xué)依據(jù)；建立設(shè)備運(yùn)行故障分析表，它是使用經(jīng)驗(yàn)的高度概括總結(jié)，有助于對(duì)故障現(xiàn)象迅速做出判斷；具備一定檢測(cè)手段，可對(duì)故障做出準(zhǔn)確的定量分析。   （5）驗(yàn)證可能故障原因時(shí)，一般從可能的故障原因或易檢驗(yàn)的地方 ，這樣可減少裝拆工作量，提高診斷速度。  液壓系統(tǒng)調(diào)試基本概要 液壓設(shè)備安裝、循環(huán)沖洗合格后，都要對(duì)液壓系統(tǒng)進(jìn)行必要的調(diào)整試車(chē)，使其在滿(mǎn)足各項(xiàng)技術(shù)參數(shù)的前提下，按實(shí)際生產(chǎn)工藝要求進(jìn)行必要的調(diào)整，使其在重負(fù)荷情況下也能運(yùn)轉(zhuǎn)正常。    1.1 液壓系統(tǒng)調(diào)度前的準(zhǔn)備工作     1）需調(diào)試的液壓系統(tǒng)必須在循環(huán)沖洗合格后，方可進(jìn)入調(diào)試狀態(tài)。     2）液壓驅(qū)動(dòng)的主機(jī)設(shè)備全部安裝完畢，運(yùn)動(dòng)部件狀態(tài)良好并經(jīng)檢查合格后，進(jìn)入調(diào)試狀態(tài)。     3）控制液壓系統(tǒng)的電氣設(shè)備及線路全部安裝完畢并檢查合格。
