style="text-indent:25px">油缸是工程機(jī)械很主要的部件，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(shí)間上對(duì)比：磨削缸體1米大概在1-2天的時(shí)間，滾壓缸體1米大概在10-30分鐘的時(shí)間。投入對(duì)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，能提高缸筒的表面質(zhì)量。高壓油缸的主要原材料是鋼材及其他配件，高壓油缸是為挖掘機(jī)等大型基建設(shè)備、船舶、海洋工程設(shè)備和工業(yè)設(shè)備配套的關(guān)鍵零部件，產(chǎn)品屬于中間產(chǎn)品，這也決定了本產(chǎn)業(yè)與上游產(chǎn)業(yè)原材料供應(yīng)商和下游產(chǎn)業(yè)中相關(guān)設(shè)備制造商具有較強(qiáng)的關(guān)聯(lián)性。標(biāo)準(zhǔn)高速液壓缸油缸的購買要對(duì)油缸的廠家進(jìn)行多家了解并對(duì)比。</p><div

style="text-indent:25px">液壓油缸在使用的過程中出現(xiàn)磨損是很正常的，造成這個(gè)的主要原因是：（1）液壓油缸零件公差與配合的選擇有問題；（2）相對(duì)運(yùn)動(dòng)件表面質(zhì)量差,表面硬度低或硬度差不對(duì)；（3）工作介質(zhì)(嚴(yán)重)污染或劣化；（4）高溫或低溫下零件尺寸(形狀)變化；（5）液壓油缸零件加工工藝選擇不合理,如缸筒選擇滾壓還是珩磨做精整加工以適應(yīng)不；同材料的密封件、支承環(huán)和擋圈；（6）缸零件及零件間幾何精度、表面粗糙度等有問題；（7）裝配質(zhì)量有問題；（8）缸安裝和/或連接有問題；（9）缸零件變形,尤其是活塞桿彎曲或失穩(wěn)；（10）已達(dá)到使用壽命等。</p><p style="text-indent:25px">液壓油缸的安裝注意事項(xiàng)：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(jì)要求，注意油溫和油壓的變化?？蛰d時(shí)，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(shí)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(shí)的參數(shù)進(jìn)行比較。5. 對(duì)于腳座固定式的移動(dòng)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(duì)移動(dòng)物體的液壓缸安裝時(shí)使缸與移動(dòng)物體在導(dǎo)軌面上的運(yùn)動(dòng)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(dòng)靈活，無阻滯和輕重不均勻的現(xiàn)象為宜。螺釘擰得過緊，會(huì)增加阻力，加速磨損；過松會(huì)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。液壓缸輸出力和活塞有效面積及其兩邊的壓差成正比。</p><div

style="text-indent:25px">油缸在使用方面，應(yīng)增加防止污染物侵入的措施應(yīng)采取有效措施控制污染物的侵入，如在油箱呼吸孔增裝高效能的空氣濾清器、新油必須過濾等外，還必須提高液壓缸自身的抗污染能力。污染嚴(yán)重的環(huán)境下更要注意，如井下用液壓缸應(yīng)采用氟橡膠(FRM)和丁腈橡膠(NBR)防塵圈，地面機(jī)械液壓缸應(yīng)采用丁腈橡膠防塵圈；自卸車、工程機(jī)械、工作平臺(tái)及其它設(shè)備的液壓缸的進(jìn)油口處增加過濾裝置，而為了減少進(jìn)油阻力，應(yīng)盡量提高(增大)其過流面積。密封件的材質(zhì)、形狀、壓縮量對(duì)液壓缸的使用壽命、工作效率影響淮螅除要求有可靠的密封外，還應(yīng)有較長的使用壽命和少的摩擦損失。目前全國密封件生產(chǎn)廠家很多，選擇質(zhì)量可靠穩(wěn)定的優(yōu)良密封件也是至關(guān)重要的。不同的液壓油選用不同材質(zhì)的油封，以保證液壓缸的壽命。東莞高低壓油缸</p><p style="text-indent:25px">液壓油缸的安裝要注意平行度和直線度。東莞高低壓油缸</p><p style="text-indent:25px">液壓油缸主要有什么特點(diǎn)？1、由于氣動(dòng)系統(tǒng)使用壓力一般在0.2-1.0Mpa范圍，因此氣缸是不能做大功率的動(dòng)力元件。液壓缸就可以做比較大的功率的元件，使用液壓系統(tǒng)。2、從介質(zhì)講空氣是可以用之不竭的，沒有費(fèi)用和供應(yīng)上的困難，將用過的氣體直接排入大氣，處理方便，不會(huì)污染，液壓油則相反。3、空氣黏度小，阻力就小于液壓油。4、但空氣的壓縮率遠(yuǎn)大于液壓油，所以它的工作平穩(wěn)性和響應(yīng)方面就差很遠(yuǎn)。液壓缸是液壓系統(tǒng)中較重要的執(zhí)行元件，它將液壓能轉(zhuǎn)換機(jī)械能，并與各種傳動(dòng)機(jī)構(gòu)相配合，完成各種的機(jī)械運(yùn)動(dòng)。液壓缸具有結(jié)構(gòu)簡單、輸出力大、性能穩(wěn)定可靠、使用維護(hù)方便、應(yīng)用范圍普遍等特點(diǎn)。東莞高低壓油缸</p></p><br
