style="text-indent:25px">液壓系統(tǒng)的常見故障：液壓沖擊。原因：執(zhí)行元件換向及閥門關閉使流動的液體因慣性和某些液壓元件反應動作不夠靈敏而產生瞬時壓力峰值，稱液壓沖擊。其峰值可超過工作壓力的幾倍，鄭州低壓液壓系統(tǒng)規(guī)格。危害：引起振動，產生噪聲；使繼電器、順序閥等壓力元件產生錯誤動作，甚至造成某些元件、密封裝置和管路損壞。措施：找出沖擊原因避免液流速度的急劇變化，鄭州低壓液壓系統(tǒng)規(guī)格。延緩速度變化的時間，估算出壓力峰值，采用相應措施，鄭州低壓液壓系統(tǒng)規(guī)格。如將流動換向閥和電磁換向閥聯(lián)用，可有效地防止液壓沖擊。液壓試驗臺的使用是需要檢查油泵、電機轉向是否正確的。鄭州低壓液壓系統(tǒng)規(guī)格</p><div

style="text-indent:25px">一個液壓系統(tǒng)工作是否正常，關鍵取決于兩個主要工作參數(shù)即壓力和流量是否處于正常的工作狀態(tài)，以及系統(tǒng)溫度和執(zhí)行器速度等參數(shù)的正常與否。液壓系統(tǒng)的故障現(xiàn)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(xiàn)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(tǒng)壓力、流量或方向等各方面的故障，這給液壓系統(tǒng)故障診斷帶來極大困難。參數(shù)測量法診斷故障的思路是這樣的，任何液壓系統(tǒng)工作正常時，系統(tǒng)參數(shù)都工作在設計和設定值附近，工作中如果這些參數(shù)偏離了預定值，則系統(tǒng)就會出現(xiàn)故障或有可能出現(xiàn)故障。鄭州低壓液壓系統(tǒng)規(guī)格液壓泵站是整個液壓系統(tǒng)或液壓站尤為重要的部件之一。</p><div

style="text-indent:25px">液壓系統(tǒng)的故障診斷是建立在運行記錄及某些系統(tǒng)參數(shù)基礎之上的。建立系統(tǒng)運行記錄，這是預防、發(fā)現(xiàn)和處理故障的科學依據(jù)；建立設備運行故障分析表，它是使用經(jīng)驗的高度概括總結，有助于對故障現(xiàn)象迅速做出判斷；具備一定檢測手段，可對故障做出準確的定量分析。液壓系統(tǒng)故障診斷方法：日常查找液壓系統(tǒng)故障的傳統(tǒng)方法是邏輯分析逐步逼近斷?；舅悸肥蔷C合分析、條件判斷。即維修人員通過觀察、聽、觸摸和簡單的測試以及對液壓系統(tǒng)的理解，憑經(jīng)驗來判斷故障發(fā)生的原因。當液壓系統(tǒng)出現(xiàn)故障時，故障根源有許多種可能。</p><p style="text-indent:25px">控制液壓系統(tǒng)泄漏的控制方案：減少沖擊和振動。為了減少承受沖擊和振動的管接頭松動引起的液壓系統(tǒng)的泄漏，可以采取以下措施：①使用減震支架固定所有管子以便吸收沖擊和振動；②使用低沖擊閥或蓄能器來減少沖擊；③適當布置壓力控制閥來保護系統(tǒng)的所有元件；④盡量減少管接頭的使用數(shù)量，管接頭盡量用焊接連接；⑤使用直螺紋接頭，三通接頭和彎頭代替錐管螺紋接頭；⑥盡量用回油塊代替各個配管；⑦針對使用的較高壓力，規(guī)定安裝時使用螺栓的扭矩和堵頭扭矩，防止結合面和密封件被蠶食；⑧正確安裝管接頭。液壓系統(tǒng)產生故障的實質就是系統(tǒng)工作參數(shù)的異常變化。</p><div
