style="text-indent:25px">液壓系統(tǒng)如果液壓回路中某點(diǎn)的工作參數(shù)不正常，則系統(tǒng)已發(fā)生了故障或可能發(fā)生了故障，需維修人員馬上進(jìn)行處理。這樣在參數(shù)測(cè)量的基礎(chǔ)上，再結(jié)合邏輯分析法，即可快速、準(zhǔn)確地找出故障所在。參數(shù)測(cè)量法不僅可以診斷系統(tǒng)故障，而且還能預(yù)報(bào)可能發(fā)生的故障，并且這種預(yù)報(bào)和診斷都是定量的，很大提高了診斷的速度和準(zhǔn)確性。這種檢測(cè)為直接測(cè)量，檢測(cè)速度快，誤差小，檢測(cè)設(shè)備簡(jiǎn)單，便于在生產(chǎn)現(xiàn)場(chǎng)推廣使用。適合于任何液壓系統(tǒng)的檢測(cè)。測(cè)量時(shí)，既不需停機(jī)，又不損壞液壓系統(tǒng)，幾乎可以對(duì)系統(tǒng)中任何部位進(jìn)行檢測(cè)，不但可診斷已有故障，而且可進(jìn)行在線監(jiān)測(cè)、預(yù)報(bào)潛在故障。</p><p style="text-indent:25px">液壓系統(tǒng)的故障有流量損失，在液壓系統(tǒng)中，各被壓元件都有相對(duì)運(yùn)動(dòng)的表面，如液壓缸內(nèi)表面和活塞外表面，因?yàn)橐邢鄬?duì)運(yùn)動(dòng)，所以它們之間都有一定的間隙。如果間隙的一邊為高壓油，另一邊為低壓油，則高壓油就會(huì)經(jīng)間隙流向低壓區(qū)從而造成泄漏。同時(shí)，由于液壓元件密封不完善，一部分油液也會(huì)向外部泄漏。這種泄漏造成的實(shí)際流量有所減少，這就是我們所說(shuō)的流量損失。流量損失影響運(yùn)動(dòng)速度，而泄漏又難以一定避免，所以在液壓系統(tǒng)中泵的額定流量要略大于系統(tǒng)工作時(shí)所需的較大流量。通常也可以用系統(tǒng)工作所需的較大流量乘以一個(gè)1.1~1.3的系數(shù)來(lái)估算。液壓站是**的液壓裝置，它按驅(qū)動(dòng)裝置要求供油。</p><div

style="text-indent:25px">液壓系統(tǒng)可以在靜密封件在剛性固定表面之間防止油液外泄。合理設(shè)計(jì)密封槽尺寸及公差，使安裝后的密封件到一定擠壓產(chǎn)生變形以便填塞配合表面的微觀凹陷，并把密封件內(nèi)應(yīng)力提高到高于被密封的壓力。當(dāng)零件剛度或螺栓預(yù)緊力不夠大時(shí)，配合表面將在油液壓力作用下分離，造成間隙或加大由于密封表面不夠平而可能從開(kāi)始就存在的間隙。隨著配合表面的運(yùn)動(dòng)，靜密封就成了動(dòng)密封。粗糙的配合表面將磨損密封件，變動(dòng)的間隙將蠶食密封件邊緣。密封件過(guò)早變質(zhì)可能是由多種因素引起的，一個(gè)重要因素是油溫過(guò)高。溫度每升高10℃則密封件壽命就會(huì)減半，所以應(yīng)合理設(shè)計(jì)高效液壓系統(tǒng)或設(shè)置強(qiáng)制冷卻裝置，使較佳油液溫度保持在65℃以下。液壓泵的泄油管應(yīng)直接接油箱，回油背壓應(yīng)不大于0.05MPa。液壓配件哪里賣</p><p
