style="text-indent:25px">蓄能器的作用是將液壓系統(tǒng)中的壓力油儲(chǔ)存起來(lái)，在需要時(shí)又重新放出。其主要作用表現(xiàn)在以下幾個(gè)方面。某些液壓系統(tǒng)的執(zhí)行元件是間歇?jiǎng)幼?，總的工作時(shí)間很短，有些液壓系統(tǒng)的執(zhí)行元件雖然不是間歇?jiǎng)幼?，但在一個(gè)工作循環(huán)內(nèi)(或一次行程內(nèi))速度差別很大。在這種系統(tǒng)中設(shè)置蓄能器后，即可采用一個(gè)功率較小的泵，以減小主傳動(dòng)的功率，使整個(gè)液壓系統(tǒng)的尺寸小、重量輕、價(jià)格便宜。對(duì)某些系統(tǒng)要求當(dāng)泵發(fā)生故障或停電(對(duì)執(zhí)行元件的供油突然中斷)時(shí)，執(zhí)行元件應(yīng)繼續(xù)完成必要的動(dòng)作。為了安全起見(jiàn)，液壓缸的活塞桿必須內(nèi)縮到缸內(nèi)。在這種場(chǎng)合下，需要有適當(dāng)容量的蓄能器作緊急動(dòng)力源。</p><p style="text-indent:25px">只要測(cè)得液壓系統(tǒng)回路中所需任意點(diǎn)處工作參數(shù)，將其與系統(tǒng)工作的正常值相比較，即可判斷出系統(tǒng)工作參數(shù)是否正常，是否發(fā)生了故障以及故障的所在部位。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，用通用儀器采用間接測(cè)量法測(cè)量時(shí)，首先需利用物理效應(yīng)將這些非電量轉(zhuǎn)換成電量，然后經(jīng)放大、轉(zhuǎn)換和顯示等處理，被測(cè)參數(shù)則可用轉(zhuǎn)換后的電信號(hào)表示并顯示。由此可判斷液壓系統(tǒng)是否有故障。但這種間接測(cè)量方法需各種傳感器，檢測(cè)裝置較復(fù)雜，測(cè)量結(jié)果誤差大、不直觀，不便于現(xiàn)場(chǎng)推廣使用。不斷變化的市場(chǎng)環(huán)境中，工業(yè)液壓系統(tǒng)無(wú)法免受發(fā)展的影響。</p><div

style="text-indent:25px">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。銅陵液壓系統(tǒng)質(zhì)量怎么樣</p><p
