style="text-indent:25px">必須保證液控單向閥有足夠的控制壓力，不允許控制壓力失壓，應(yīng)注意控制壓力是否滿足反向開(kāi)啟的要求。如果液控單向閥的控制為自主系統(tǒng)時(shí)，則要分析主系統(tǒng)壓力的變化對(duì)控制油路壓力的影響，以免出現(xiàn)液控單向閥的誤動(dòng)作。根據(jù)液控單向閥在液壓系統(tǒng)中的位置或反向出油腔后的液流阻力（背壓）大小，合理選擇液控單向閥的結(jié)構(gòu)（簡(jiǎn)式或復(fù)式）及泄油方式（內(nèi)泄或外泄)。對(duì)于內(nèi)泄式液控單向閥來(lái)說(shuō)，當(dāng)反向油口壓力超過(guò)一定值時(shí)，液控部分將失去控制作用，故內(nèi)泄式液控單向閥一般用于反向出油腔無(wú)背壓或背壓較小的場(chǎng)合；而外泄式液控單向閥可用于反向出油腔背壓較高的場(chǎng)合，以降低較小的控制壓力，節(jié)省控制功率。系統(tǒng)若采用內(nèi)泄式，則柱塞缸將斷續(xù)下降發(fā)出振動(dòng)和噪聲。當(dāng)反向進(jìn)油腔壓力較高時(shí)，則用帶卸荷閥芯的液控單向閥，此時(shí)控制油壓力降低為原來(lái)的幾分之一至幾十分之一。如果選用了外泄式液控單向閥，應(yīng)注意將外泄口單獨(dú)接至油箱。另外，液壓缸無(wú)桿腔與有桿腔之比不能太大，否則會(huì)造成液控單向閥打不開(kāi)。常州液壓系統(tǒng)介紹執(zhí)行部分含有液壓缸或液壓馬達(dá)，其可按實(shí)際要求來(lái)選擇。</p><div

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。</p><p style="text-indent:25px">不同種類的液壓泵所產(chǎn)生的故障原因也是多種多樣的，其中主要原因是由于液壓泵本身內(nèi)部元件磨損嚴(yán)重或損壞，導(dǎo)致內(nèi)泄漏大。像柱塞泵的缸體與配流盤、柱塞與柱塞孔等配合件的磨損、拉傷，都會(huì)造成液壓泵內(nèi)泄漏嚴(yán)重;齒輪泵的齒頂和泵殼之間磨損，泵軸受不平衡力，磨損嚴(yán)重，導(dǎo)致內(nèi)泄露大;葉片泵配油盤的表面、定子的內(nèi)曲面和轉(zhuǎn)子的兩側(cè)面磨損較大，造成內(nèi)部泄露增大。還有就是，泵在吸油過(guò)程中，阻力太大、油液粘度太高或者泵軸轉(zhuǎn)速太快等原因，使得泵吸油困難，導(dǎo)致內(nèi)摩擦引起的發(fā)熱后，液壓泵構(gòu)成的零部件間配合間隙變大，這就很容易出現(xiàn)壓力低或失壓的現(xiàn)象。液壓油泵與控制閥間管道相連接。</p><div

style="text-indent:25px">無(wú)高速換向沖擊這是在大功率液壓系統(tǒng)中較容易出現(xiàn)也感到頭疼的問(wèn)題。仰仗于插裝閥為尺寸緊湊的錐閥式結(jié)構(gòu)，切換時(shí)控制容積小，且無(wú)滑閥式閥的“正遮蓋”概念，因而可高速切換，通過(guò)對(duì)先導(dǎo)部分的元件采取一些措施和適應(yīng)切換過(guò)程中過(guò)渡狀態(tài)的控制，可較大減輕切換時(shí)的換向沖擊。具有高的切換可靠性一般錐閥式閥難以因污物而引起動(dòng)作不良，壓力損失小、發(fā)熱小，加之閥芯有一段較長(zhǎng)的導(dǎo)向部分，不易產(chǎn)生歪斜卡死現(xiàn)象，因而動(dòng)作可靠。插裝邏輯閥便于集成化可以將多個(gè)元件集中在一個(gè)塊體內(nèi)，構(gòu)成一個(gè)液壓邏輯控制系統(tǒng)，較之用常規(guī)的壓力、方向和流量閥組成的系統(tǒng)重量可減輕1／3～1／4，效率可提高2％～4％。液壓泵出的油通過(guò)控制閥流向活塞底部大腔。常州液壓系統(tǒng)介紹</p><p
