style="text-indent:25px">油液污染對(duì)系統(tǒng)的危害主要如下：油液中各種污染物引起元件各種形式的磨損，固體顆粒進(jìn)入運(yùn)動(dòng)副間隙中，對(duì)零件表面產(chǎn)生切削磨損或是疲勞磨損。高速液流中的固體顆粒對(duì)元件的表面沖擊引起沖蝕磨損。油液中的水和油液氧化變質(zhì)的生成物對(duì)元件產(chǎn)生腐蝕作用。此外，系統(tǒng)的油液中的空氣引起氣蝕，導(dǎo)致元件表面剝蝕和破壞。固體顆粒堵塞液壓閥的間隙和孔口，引起閥芯阻塞和卡緊，影響工作性能，甚至導(dǎo)致嚴(yán)重的事故。油液中的水和空氣以其熱能是油液氧化的主要條件，而油液中的金屬微粒對(duì)油液的氧化起重要催化作用，此外，油液中的水和懸浮氣泡明顯降低了運(yùn)動(dòng)副間油膜的強(qiáng)度，使?jié)櫥阅芙档?。液壓系統(tǒng)中的工作參數(shù)，如壓力、流量、溫度等都是非電物理量。福州液壓系統(tǒng)多少錢</p><p

style="text-indent:25px">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。基本思路是綜合分析、條件判斷。即維修人員通過(guò)觀察、聽(tīng)、觸摸和簡(jiǎn)單的測(cè)試以及對(duì)液壓系統(tǒng)的理解，憑經(jīng)驗(yàn)來(lái)判斷故障發(fā)生的原因。當(dāng)液壓系統(tǒng)出現(xiàn)故障時(shí)，故障根源有許多種可能。采用邏輯代數(shù)方法，將可能故障原因列表，然后根據(jù)先易后難原則逐一進(jìn)行邏輯判斷，逐項(xiàng)逼近，找出故障原因和引起故障的具體條件。故障診斷過(guò)程中要求維修人員具有液壓系統(tǒng)基礎(chǔ)知識(shí)和較強(qiáng)的分析能力，方可保證診斷的效率和準(zhǔn)確性。但診斷過(guò)程較繁瑣，須經(jīng)過(guò)大量的檢查，驗(yàn)證工作，而且只能是定性地分析，診斷的故障原因不夠準(zhǔn)確。為減少系統(tǒng)故障檢測(cè)的盲目性和經(jīng)驗(yàn)性以及拆裝工作量，傳統(tǒng)的故障診斷方法已遠(yuǎn)不能滿足現(xiàn)代液壓系統(tǒng)的要求。隨著液壓系統(tǒng)向大型化、連續(xù)生產(chǎn)、自動(dòng)控制方向發(fā)展，又出現(xiàn)了多種現(xiàn)代故障診斷方法。如鐵譜技斷，可從油液中分離出來(lái)的各種磨粒的數(shù)量、形狀、尺寸、成分以及分布規(guī)律等情況，及時(shí)、準(zhǔn)確地判斷出系統(tǒng)中元件的磨損部位、形式、程度等。而且可對(duì)液壓油進(jìn)行定量的污染分析和評(píng)價(jià)，做到在線檢測(cè)和故障預(yù)防。福州液壓系統(tǒng)多少錢</p></p><br
