style="text-indent:25px">液壓是由兩個大小不同的液缸組成的，在液缸里充滿水或油。充水的叫"水壓機(jī)"充油的稱油壓機(jī)。兩個液缸里各有一個可以滑動的活塞，如果在小活塞上加一定值的壓力，根據(jù)帕斯卡定律，小活塞將這一壓力通過液體的壓力傳遞給大活塞，將大活塞頂上去。設(shè)小活塞的橫截面積是S1，加在小活塞上的向下的壓力是F1。于是，小活塞對液體的壓強(qiáng)為P=F1/SI，能夠大小不變地被液體向各個方向傳遞"。大活塞所受到的壓強(qiáng)必然也等于P。若大活塞的橫截面積是S2，壓強(qiáng)P在大活塞上所產(chǎn)生的向上的壓力F2=PxS2，截面積是小活塞橫截面積的倍數(shù)。從上式知，在小活塞上加一較小的力，則在大活塞上會有很大的力，為此用液壓機(jī)來壓制膠合板、榨油、提取重物、鍛壓鋼材等。液壓原理在一定的機(jī)械、電子系統(tǒng)內(nèi)，依靠液體介質(zhì)的靜壓力，完成積壓、傳遞、放大，實現(xiàn)機(jī)械功能的輕巧化、科學(xué)化。利用液壓原理，可以構(gòu)建液壓傳動系統(tǒng)，也可以構(gòu)建液壓控制系統(tǒng)。</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?；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(dāng)液壓系統(tǒng)出現(xiàn)故障時，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，逐項逼近，找出故障原因和引起故障的具體條件。故障診斷過程中要求維修人員具有液壓系統(tǒng)基礎(chǔ)知識和較強(qiáng)的分析能力，方可保證診斷的效率和準(zhǔn)確性。但診斷過程較繁瑣，須經(jīng)過大量的檢查，驗證工作，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)故障檢測的盲目性和經(jīng)驗性以及拆裝工作量，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、準(zhǔn)確地判斷出系統(tǒng)中元件的磨損部位、形式、程度等。而且可對液壓油進(jìn)行定量的污染分析和評價，做到在線檢測和故障預(yù)防。油箱、泵、控制閥、油缸、連接管路和溢流閥組成了基本液壓系統(tǒng)。</p><div

style="text-indent:25px">液壓缸零件材料如果制造液壓缸的材料具有較好的強(qiáng)度、韌性及抗腐蝕性，則其抗氣蝕能力較好;否則易發(fā)生氣蝕。另外材料組織的均勻度對氣蝕產(chǎn)生的影響也較大，材料組織越不均勻，在其強(qiáng)度薄弱處及抗腐蝕性低的地方就容易產(chǎn)生氣蝕。液壓油質(zhì)量液壓油質(zhì)量的好壞，是液壓缸是否產(chǎn)生氣蝕的一個重要因素。液壓油在工作中不可避免地與閥門、管路等發(fā)生沖擊，如果液壓油的抗泡沫性差，就很容易產(chǎn)生泡沫，從而導(dǎo)致液壓缸等部位產(chǎn)生氣蝕。若液壓油壓力變化頻率過快、過高，也將促使氣泡的形成，并加速氣泡的破裂速度。比如液壓缸進(jìn)、回油口處，由于壓力變化頻率相對較高，氣蝕的程度也相對高于其他部位。制造及維修液壓缸裝配或維修質(zhì)量對其氣蝕的影響也不可小視。如果在裝配或維修時未對液壓系統(tǒng)充分排氣，將導(dǎo)致系統(tǒng)中存在氣體，在高溫、高壓的作用下，液壓缸將產(chǎn)生氣蝕。池州液壓系統(tǒng)多少錢</p></p><br
