HYDAC蓄能器相比都有什么特點
    與其他形式HYDAC蓄能器比較，它具有油氣隔離，油不易老化，反應靈敏，尺寸小，重量輕等特點。在液壓系統中起儲存能量，穩定壓力、減少液壓泵功率，補償漏損，吸收沖擊壓力和脈動壓力等多種作用。液體在壓力作用下,體積的變化(在溫度不變的情況下)非常的微小,所以如果沒有動力源(也就是高壓液體的補充),液體的壓力會迅速降低.而氣體的彈性則要大得多,因為氣體是可壓縮的,在有較大的體積變化情況下,氣體仍然有可能保持相對高的壓力.因此,蓄能器在進行液壓系統的液壓油補充時,液體的體積已經變化的情況下,高壓的氣體可以繼續維持液壓油的壓力,而不于由于液壓油的補充,容器內的液壓油體積變小,導致液壓油的迅速失壓.
    關于蓄能器設置的簡單問題介紹：蓄能器設置后，開始每周檢查膠囊氣壓次，月后，每月次，半年后，半年檢查次，年后，每年檢查次。定期檢查可以保持*使用條件，并及早發現泄漏及時修復使用。
    在HYDAC蓄能器的進油口和油箱連接的油路上設置個截止閥，并在截止閥前裝上個壓力表，慢慢打開截止閥，使壓力油倒流回油箱，同時注意壓力表，壓力表指針是慢慢下降，達到某壓力值后急速降到零，指針移動的速度發生變化的數值，就是充氣壓力。此外，還可以利用充氣工具直接檢查充氣壓力，但每檢查次都會放掉點氣體。
    蓄能器在使用過程中防泄漏，要定期對氣囊進行氣密性檢查及其他方面的檢查。因此，日常檢查與維護保養不可少。日常檢查即用目視、聽覺和手摸及儀表等簡單的方法進行外觀及狀態的檢查，檢查時既要檢查局部也要注意設備整體。在檢查中發現的異常情況，對妨礙蓄能器繼續工作的應作應急處理；對其他的則應仔細雨觀察并記錄，到定期維護時予以解決。些損壞的零部件也需要及時更換。主動維護是繼故障維修、預防維修、狀態維修后，上來提出的種新的設備管理理論。它的定義是：對導致設備損壞的根源性參數進行修復，從而地防止失效的發生，延長設備的使用壽命。主動維護是在設備磨損之前針對其根源問題采取的措施，地控制磨損及失效的發生，從而大幅度地延長修理周期。主動維護不但為液壓設備與元件可造運行提供，同時可大幅度降低維修成本。[1]
    HYDAC蓄能器在液壓系統中屬于危險部件，所以在操作過程中要特別注意安全。蓄能器故障診斷與排除，既包括蓄能器本身故障的診斷與排除，又涉及蓄能器所在液壓系統的故障診斷與排除，兩者之間相互交織。故障診斷的主要工作內容有：
    ①判定故障的性質與嚴重程度。根據現場狀況，判斷是否存在故障，是什么性質的問題（壓力、速度、動作還是其他），問題的嚴重程度（正常、輕微故障、般故障、還是嚴重故障）。
    ②查找失效元件及失效位置。根據癥狀及相關信息，找出故障點，以便進步排除故障，這里主要弄清“問題出在何處”。
    ③進步查找引起故障的初始原因。如液壓油污染，元件性低，環境因素不合要求等。這里主要弄清故障的外部原因。
    ④機理分析。對故障的因果關系鏈進行深入地分析與探討，弄清問題產生的來龍去脈。⑤預測故障發展趨向。根據系統磨損劣化的現狀及速度、元件使用壽命的理論與經驗數據，預測蓄能器或液壓系統將來的狀況。
    分析、對比、統計、歸納與綜合，找出規律。
