SMC液壓缸的安裝注(zhu)意(yi)事項：

1、液壓油缸安裝時，要(yao)特(te)別(bie)注意安裝時的垂(chui)直度(du)和平(ping)行(xing)度(du)等的尺寸精度(du)。為(wei)此(ci)安裝前，要(yao)先檢查活(huo)塞(sai)桿(gan)是否(fou)彎曲，特(te)別(bie)是對(dui)長行(xing)程液壓油缸，活(huo)塞(sai)桿(gan)彎曲會造成缸蓋(gai)密封損(sun)壞(huai)，導致泄漏、爬行(xing)和動作失(shi)靈等故障，并(bing)且加劇活(huo)塞(sai)桿(gan)與導向套之間的偏(pian)磨損(sun)現象(xiang)。

2、液(ye)壓油缸(gang)(gang)軸(zhou)心(xin)線應與安裝面及(ji)導軌(gui)面平(ping)行(xing)(xing)，特別是要注意活塞桿全(quan)部伸出時的情況。 若二者不平(ping)行(xing)(xing)，會產生(sheng)較大(da)的側向力(li)，造成液(ye)壓缸(gang)(gang)別勁(jing)、換向不良、爬行(xing)(xing)和液(ye)壓缸(gang)(gang)密封損壞失效(xiao)等(deng)故障。一(yi)般(ban)可以導軌(gui)面為(wei)基準，用百分(fen)表(biao)調整液(ye)壓缸(gang)(gang)，使活塞桿（08mm／m母線與V形導軌(gui)（或(huo)圓柱導軌(gui)）平(ping)行(xing)(xing)，上母線與平(ping)導軌(gui)平(ping)行(xing)(xing)，允(yun)差為(wei)o．04～o．08mm／m。活塞桿軸(zhou)心(xin)線對(dui)兩端支座的安裝面，其平(ping)行(xing)(xing)度誤差不得大(da)于0.05mm。

SMC液壓缸的工作原理：
SMC液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)是液(ye)(ye)(ye)壓(ya)(ya)傳(chuan)動(dong)(dong)(dong)系(xi)統中(zhong)的(de)執行元件， 它是把液(ye)(ye)(ye)壓(ya)(ya)能(neng)(neng)(neng)轉(zhuan)(zhuan)換成(cheng)(cheng)(cheng)機(ji)(ji)械能(neng)(neng)(neng)的(de)能(neng)(neng)(neng)量轉(zhuan)(zhuan)換裝(zhuang) 置(zhi)(zhi)。液(ye)(ye)(ye)壓(ya)(ya)馬達實(shi)現(xian)的(de)是連續回轉(zhuan)(zhuan)運(yun)動(dong)(dong)(dong)，而液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)實(shi)現(xian)的(de)則是往(wang)(wang)復(fu)運(yun)動(dong)(dong)(dong)。液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)的(de)結(jie)(jie)構 型式有活(huo)塞(sai)缸(gang)(gang)、柱(zhu)塞(sai)缸(gang)(gang)、擺動(dong)(dong)(dong)缸(gang)(gang)三大類(lei)，活(huo) 塞(sai)缸(gang)(gang)和(he)柱(zhu)塞(sai)缸(gang)(gang)實(shi)現(xian)往(wang)(wang)復(fu)直(zhi)線運(yun)動(dong)(dong)(dong)，輸(shu)出速(su)度 和(he)推力(li)(li)，擺動(dong)(dong)(dong)缸(gang)(gang)實(shi)現(xian)往(wang)(wang)復(fu)擺動(dong)(dong)(dong)，輸(shu)出角速(su)度 （轉(zhuan)(zhuan)速(su)） 和(he)轉(zhuan)(zhuan)矩。液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)除了單(dan)個地(di)使用(yong)(yong) 外，還(huan)可(ke)以兩個或多個地(di)組(zu)合起(qi)(qi)來或和(he)其(qi)他(ta)(ta) 機(ji)(ji)構組(zu)合起(qi)(qi)來使用(yong)(yong)。以完成(cheng)(cheng)(cheng)特殊的(de)功用(yong)(yong)。液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)結(jie)(jie)構簡(jian)單(dan)，工(gong)作可(ke)靠，在機(ji)(ji)床(chuang)的(de) 液(ye)(ye)(ye)壓(ya)(ya)系(xi)統中(zhong)得到(dao)了廣(guang)泛(fan)的(de)應用(yong)(yong)。液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)是將液(ye)(ye)(ye)壓(ya)(ya)能(neng)(neng)(neng)轉(zhuan)(zhuan)變為機(ji)(ji)械能(neng)(neng)(neng)的(de)、做(zuo)直(zhi)線往(wang)(wang)復(fu)運(yun)動(dong)(dong)(dong)（或擺動(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)）的(de)液(ye)(ye)(ye)壓(ya)(ya)執行元件。它結(jie)(jie)構簡(jian)單(dan)、工(gong)作可(ke)靠。用(yong)(yong)它來實(shi)現(xian)往(wang)(wang)復(fu)運(yun)動(dong)(dong)(dong)時，可(ke)免去減速(su)裝(zhuang)置(zhi)(zhi)，并(bing)且沒(mei)有傳(chuan)動(dong)(dong)(dong)間隙(xi)，運(yun)動(dong)(dong)(dong)平穩，因此在各種(zhong)機(ji)(ji)械的(de)液(ye)(ye)(ye)壓(ya)(ya)系(xi)統中(zhong)得到(dao)廣(guang)泛(fan)應用(yong)(yong)。液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)輸(shu)出力(li)(li)和(he)活(huo)塞(sai)有效面積及其(qi)兩邊(bian)的(de)壓(ya)(ya)差成(cheng)(cheng)(cheng)正(zheng)比；液(ye)(ye)(ye)壓(ya)(ya)缸(gang)(gang)基(ji)本上由缸(gang)(gang)筒(tong)和(he)缸(gang)(gang)蓋、活(huo)塞(sai)和(he)活(huo)塞(sai)桿、密封裝(zhuang)置(zhi)(zhi)、緩(huan)沖裝(zhuang)置(zhi)(zhi)與(yu)排氣(qi)裝(zhuang)置(zhi)(zhi)組(zu)成(cheng)(cheng)(cheng)。緩(huan)沖裝(zhuang)置(zhi)(zhi)與(yu)排氣(qi)裝(zhuang)置(zhi)(zhi)視具體應用(yong)(yong)場合而定(ding)，其(qi)他(ta)(ta)裝(zhuang)置(zhi)(zhi)則*。
