style="text-indent:25px">一個(gè)液壓系統(tǒng)工作是否正常，關(guān)鍵取決于兩個(gè)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(yīng)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(shí)，系統(tǒng)參數(shù)都工作在設(shè)計(jì)和設(shè)定值附近，工作中如果這些參數(shù)偏離了預(yù)定值，則系統(tǒng)就會(huì)出現(xiàn)故障或有可能出現(xiàn)故障。液壓彎管機(jī)報(bào)價(jià)液壓站是由泵裝置、集成塊或閥組合、油箱、電氣盒組合而成。</p><div

style="text-indent:25px">液壓站的結(jié)構(gòu)形式：1）活塞式，單活塞桿液壓缸只有一端有活塞桿。單活塞液壓缸其兩端進(jìn)出口油口A和B都可通壓力油或回油，以實(shí)現(xiàn)雙向運(yùn)動(dòng)，故稱為雙作用缸。2）柱塞式：①柱塞式液壓缸是一種單作用式液壓缸，靠液壓力只能實(shí)現(xiàn)一個(gè)方向的運(yùn)動(dòng)，柱塞回程要靠其它外力或柱塞的自重；②柱塞只靠缸套支承而不與缸套接觸，這樣缸套極易加工，故適于做長行程液壓缸；③工作時(shí)柱塞總受壓，因而它必須有足夠的剛度；④柱塞重量往往較大，水平放置時(shí)容易因自重而下垂，造成密封件和導(dǎo)向單邊磨損，故其垂直使用更有利。3）伸縮式，伸縮式液壓缸具有二級或多級活塞，伸縮式液壓缸中活塞伸出的順序式從大到小，而空載縮回的順序則一般是從小到大。伸縮缸可實(shí)現(xiàn)較長的行程，而縮回時(shí)長度較短，結(jié)構(gòu)較為緊湊。此種液壓缸常用于工程機(jī)械和農(nóng)業(yè)機(jī)械上。4）擺動(dòng)式，擺動(dòng)式液壓缸是輸出扭矩并實(shí)現(xiàn)往復(fù)運(yùn)動(dòng)的執(zhí)行元件，也稱擺動(dòng)式液壓馬達(dá)。有單葉片和雙葉片兩種形式。定子塊固定在缸體上，而葉片和轉(zhuǎn)子連接在一起。根據(jù)進(jìn)油方向，葉片將帶動(dòng)轉(zhuǎn)子作往復(fù)擺動(dòng)。</p><p style="text-indent:25px">液壓系統(tǒng)的優(yōu)點(diǎn)：1、體積小和重量輕；2、剛度大、精度高、響應(yīng)**、驅(qū)動(dòng)力大，適合重載直接驅(qū)動(dòng)；4、調(diào)速范圍寬，速度控制方式多樣；5、自潤滑、自冷卻和長壽命；6、易于實(shí)現(xiàn)安全保護(hù)。液壓系統(tǒng)的常見故障：壓力損失。由于液體具有黏性，在管路中流動(dòng)時(shí)又不可避免地存在著摩擦力，所以液體在流動(dòng)過程中必然要損耗一部分能量。這部分能量損耗主要表現(xiàn)為壓力損失。壓力損失有沿程損失和局部損失兩種。沿程損失是當(dāng)液體在直徑不變的直管中流過一段距離時(shí)，因摩擦而產(chǎn)生的壓力損失。局部損失是由于管路截面形狀突然變化、液流方向改變或其他形式的液流阻力而引起的壓力損失?？偟膲毫p失等于沿程損失和局部損失之和。由于壓力損失的必然存在，所以泵的額定壓力要略大于系統(tǒng)工作時(shí)所需的較大工作壓力，一般可將系統(tǒng)工作所需的較大工作壓力乘以一個(gè)1.3~1.5的系數(shù)來估算。按液壓泵組輸出流量特性，可將液壓泵站分為定量型和變量型兩種。</p><div
