style="text-indent:25px">油缸的安裝要注意缸與導(dǎo)軌的平行度和直線度，其偏差應(yīng)在0.1毫米/全長(zhǎng)之內(nèi)。如果液壓缸上母線全長(zhǎng)超差，應(yīng)修刮液壓缸的支架底面或修刮機(jī)床的接觸面來(lái)達(dá)到要求；如果側(cè)母線超差、可松開液壓缸和固定螺釘，拔掉定位鎖，校正其側(cè)母線的精度。拆裝液壓缸時(shí)，嚴(yán)防損傷活塞桿頂端的螺紋、缸口螺紋和活塞桿表面。嚴(yán)禁用錘打缸筒和活塞表面，如缸孔和活塞表面有損失，不允許用砂紙打磨，要用細(xì)油石精心研磨。油缸的軸向兩端不能固定死，且一端必須保持浮動(dòng)以防止熱膨脹的影響。由于缸內(nèi)受液壓力和熱膨脹等因素的作用，有軸向伸縮。若缸兩端固定死，將導(dǎo)致缸各部分變形。</p><p 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(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)類型選擇液壓執(zhí)行器的設(shè)計(jì)壓力。平時(shí)要經(jīng)常清理油缸動(dòng)密封防塵圈部位和裸露的活塞桿上的泥沙。</p><div
