 設備調試階段的故障率較高，存在問題較為復雜，其特征是設計、制造、安裝以及管理等問題交織在一起。除機械、電氣問題外，一般液壓系統(tǒng)常見故障有：

 

 

    1)接頭連接處泄漏。

 

    2)運動速度不穩(wěn)定。

 

    3)閥心卡死或運動不靈活，造成執(zhí)行機構動作失靈。

 

    4)阻尼小孔被堵，造成系統(tǒng)壓力不穩(wěn)定或壓力調不上去。

 

    5)閥類元件漏裝彈簧或密封件，或管道接錯而使動作混亂。

 

6)設計、選擇不當，使系統(tǒng)發(fā)熱，或動作不協(xié)調，位置精度達不到要求。

 

7)液壓件加工質量差，或安裝質量差，造成閥類動作不靈活。

 

8)長期工作，密封件老化，以及易損元件磨損等，造成系統(tǒng)中內外泄漏量增加，系統(tǒng)效率明顯下降。

液壓傳動系統(tǒng)在數(shù)控機床中占有很重要的位置，加工中心的刀具自動交換系統(tǒng)(ATC)，托盤自動交換系統(tǒng)，主軸箱的平衡，主軸箱齒輪的變檔以及回轉工作臺的夾緊等一般都采用液壓系統(tǒng)來實現(xiàn)。

機床液壓設備是由機械、液壓、電氣及儀表等組成的統(tǒng)一體，分析系統(tǒng)的故障之前必須弄清楚整個液壓系統(tǒng)的傳動原理、結構特點，然后根據故障現(xiàn)象進行分析、判斷，確定區(qū)域、部位、以至于某個元件。液壓系統(tǒng)的工作是由壓力、流量、液流方向來實現(xiàn)的，可按照這些特征找出故障的原因并及時給予排除。造成故障的主要原因一般不外有三種情況：一是設計不完善或不合理；二是操作安裝有誤，使零件、部件運轉不正常；三是使用、維護、保養(yǎng)不當。前一種故障必須充分分析研究后進行改裝、完善，后兩種故障可以用修理及調整的方法解決
