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、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(gè)檔。2）F = PS，由力的計(jì)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、S有多種組合。100缸徑油缸，使用壓力打到14MPA時(shí)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、初選液壓工作壓力：壓力的選擇要根據(jù)載荷大?。碏）和設(shè)備類(lèi)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(lái)說(shuō)，對(duì)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(jì)壓力：根據(jù)主機(jī)類(lèi)型選擇液壓執(zhí)行器的設(shè)計(jì)壓力。濟(jì)南液壓油缸液壓系統(tǒng)進(jìn)行間歇性的運(yùn)作能夠提升清潔效果，一般的頻率是十分鐘一次。</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(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(wàn)——幾百萬(wàn)），滾壓刀（1仟——幾萬(wàn)）。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(shuō)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(guò)滾壓后，表面沒(méi)有鋒利的微小刃口，長(zhǎng)時(shí)間的運(yùn)動(dòng)摩擦也不會(huì)損傷密封圈或密封件，這點(diǎn)在液壓行業(yè)特別重要。在液壓油缸的工作中要控制速度適當(dāng)，不要超過(guò)2m/s。</p><div
