style="text-indent:25px">液壓油缸的選型步驟：步驟一：掌握基本概念及公式，1）油缸基本參數(shù)，缸徑D（缸筒內(nèi)徑）、桿徑d（活塞桿直徑）、行程S、使用壓力P，安裝方式，新油缸修復(fù)、安裝尺寸。其中較重要的是缸徑、行程、使用壓力缸徑有標(biāo)準(zhǔn)系列可選，使用壓力也是分幾個檔。2）F = PS，由力的計算公式可知: F = PS（P：壓強(qiáng)； S：受壓面積—由油缸的缸徑、桿徑?jīng)Q定）。舉例：油缸的推力需要達(dá)到10噸，即F=10，則P，新油缸修復(fù)、S有多種組合。100缸徑油缸，使用壓力打到14MPA時可以達(dá)到10噸，80缸徑油缸，使用壓力打到21MPA同樣可以達(dá)到10噸。步驟二：確定系統(tǒng)壓力P，1，新油缸修復(fù)、初選液壓工作壓力：壓力的選擇要根據(jù)載荷大小（即F）和設(shè)備類型而定。還要考慮執(zhí)行元件的裝配空間、經(jīng)濟(jì)條件及元件供應(yīng)情況等的限制。一般來說，對于固定的尺寸不太受限的設(shè)備，壓力可以選低一些，行走機(jī)械重在設(shè)備壓力要選高一些。2、根據(jù)負(fù)載選擇液壓缸的設(shè)計壓力：根據(jù)主機(jī)類型選擇液壓執(zhí)行器的設(shè)計壓力。液壓油缸的調(diào)和材料要嚴(yán)格按照比例進(jìn)行調(diào)和，并攪拌均勻，直到?jīng)]有色差。新油缸修復(fù)</p><div

style="text-indent:25px">油缸是工程機(jī)械較主要部件，傳統(tǒng)的加工方法是：拉削缸體——精鏜缸體——磨削缸體。采用滾壓方法是：拉削缸體——精鏜缸體——滾壓缸體，工序是3部分，但時間上對比：磨削缸體1米大概在1-2天的時間，滾壓缸體1米大概在10-30分鐘的時間。投入對比：磨床或絎磨機(jī)（幾萬——幾百萬），滾壓刀（1仟——幾萬）。滾壓后，孔表面粗糙度由幢滾前Ra3.2～6.3um減小為Ra0.4～0.8&um，孔的表面硬度提高約30%，缸筒內(nèi)表面疲勞強(qiáng)度提高25%。油缸使用壽命若只考慮缸筒影響，提高2～3倍，鏜削滾壓工藝較磨削工藝效率提高3倍左右。以上數(shù)據(jù)說明，滾壓工藝是高效的，能很大提高缸筒的表面質(zhì)量。油缸經(jīng)過滾壓后，表面沒有鋒利的微小刃口，長時間的運(yùn)動摩擦也不會損傷密封圈或密封件，這點(diǎn)在液壓行業(yè)特別重要。</p><p style="text-indent:25px">液壓油缸卸卸前后要設(shè)法創(chuàng)造條件防止液壓缸的零件被周圍的灰塵和雜質(zhì)污染。例如，拆卸時應(yīng)盡量在干凈的環(huán)境下進(jìn)行；拆卸后所有零件要用塑料布蓋好，不要用棉布或其他工作用布覆蓋。油缸拆卸后要認(rèn)真檢查，以確定哪些零件可以繼續(xù)使用，哪些零件可以修理后再用，哪些零件必須更換。油缸裝配前必須對各零件仔細(xì)清洗。油缸要正確安裝各處的密封裝置。比如在安裝O形圈時，不要將其拉到長效變形的程度，也不要邊滾動邊套裝，否則可能因形成扭曲狀而漏油。拆卸后的O形密封圈和防塵圈應(yīng)全部換新。又或者是安裝Y形和V形密封圈時，要注意其安裝方向，避免因裝反而漏油。對Y形密封圈而言，其唇邊應(yīng)對著有壓力的油腔；此外，YX形密封圈還要注意區(qū)分是軸用還是孔用，不要裝錯。V形密封圈由形狀不同的支承環(huán)、密封環(huán)和壓環(huán)組成，當(dāng)壓環(huán)壓緊密封環(huán)時，支承環(huán)可使密封環(huán)產(chǎn)生為形而起密封作用，安裝時應(yīng)將密封環(huán)的開口面向壓力油腔；調(diào)整壓環(huán)時，應(yīng)以不漏油為限，不可壓得過緊，以防密封阻力過大。在液壓油缸的工作中要控制速度適當(dāng)，不要超過2m/s。</p><div

style="text-indent:25px">液壓油缸的安裝注意事項：1. 液壓缸及周圍環(huán)境應(yīng)清潔。油箱要保證密封，防止污染。管路和油箱應(yīng)清理，防止有脫落的氧化鐵皮及其他雜物。清潔要用無絨布或**紙。不能試用麻線和黏合劑作密封材料。液壓油按設(shè)計要求，注意油溫和油壓的變化?？蛰d時，擰開排氣螺栓進(jìn)行排氣。2. 配管鏈接不得有松弛現(xiàn)象。3. 液壓缸的基座必須有足夠的剛度，否則加壓時缸筒成弓形向上翹，使活塞桿彎曲。4. 在將液壓缸安裝到系統(tǒng)之前，應(yīng)將液壓缸標(biāo)牌上的參數(shù)與訂貨時的參數(shù)進(jìn)行比較。5. 對于腳座固定式的移動缸的中心軸線應(yīng)與負(fù)載作用力的中線同心，以避免引起側(cè)向力，側(cè)向力容易使密封件磨損及活塞損壞。對移動物體的液壓缸安裝時使缸與移動物體在導(dǎo)軌面上的運(yùn)動方向保持平行，其平行度一般不大于0.05mm/m。6. 安裝液壓缸體的密封壓蓋螺釘，其擰緊程度以保證活塞在全行程上移動靈活，無阻滯和輕重不均勻的現(xiàn)象為宜。螺釘擰得過緊，會增加阻力，加速磨損；過松會引起漏油。7. 有排氣閥或排氣羅塞的液壓缸，必須將排氣閥或排氣羅塞安裝在較高點(diǎn)，以便排除空氣。油缸運(yùn)轉(zhuǎn)初期，必須完全排清油缸內(nèi)的空氣。新油缸修復(fù)</p><p
