 近年來，隨著液壓系統向大型化、連續生產、自動控制方向發展，又出現了多種現代故障診斷方法。如鐵譜技斷，可從油液中分離出來的各種磨粒的數量、形狀、尺寸、成分以及分布規律等情況，及時、準確地判斷出系統中元件的磨損部位、形式、程度等。而且可對液壓油進行定量的污染分析和評價，做到在線檢測和故障預防。再如基于人工智能的診斷系斷，它通過計算機模仿在某一領域內有經驗解決問題的方法。將故障現象通過人機接口輸入計算機，計算機根據輸入的現象以及知識庫中的知識，可推算出引起故障的原因，然后通過人機接口輸出該原因，并提出維修方案或預防措施。這些方法給液壓系統故障診斷帶來廣闊的前景，給液壓系統故障診斷自動化奠定了基礎。但這些方法大都需要昂貴的檢測設備和復雜的傳感控制系統和計算機處理系統，有些方法研究起來有一定困難。目前不適應于現場推廣使用。下面介紹一種簡單、實用的液壓系統故障診斷方法。

一個液壓系統工作是否正常，關鍵取決于兩個主要工作參數即壓力和流量是否處于正常的工作狀態，以及系統溫度和執行器速度等參數的正常與否。液壓系統的故障現象是各種各樣的，故障原因也是多種因素的綜合。同一因素可能造成不同的故障現象，而同一故障又可能對應著多種不同原因。例如：油液的污染可能造成液壓系統壓力、流量或方向等各方面的故障，這給液壓系統故障診斷帶來極大困難。
