YHG1型冶金設備標(biao)準液(ye)壓缸
Y-HG1型冶金(jin)設備(bei)標準(zhun)液(ye)(ye)壓(ya)(ya)缸(gang)，為(wei)雙作(zuo)用(yong)單活(huo)塞桿液(ye)(ye)壓(ya)(ya)缸(gang)，缸(gang)徑從40~320mm共有(you)17種規格，額定壓(ya)(ya)力為(wei)16MPa，可以帶緩沖(chong)裝(zhuang)置。該系列液(ye)(ye)壓(ya)(ya)缸(gang)有(you)13種安裝(zhuang)連接型式(shi)，除軸向腳架式(shi)外(wai)，安裝(zhuang)連裝(zhuang)尺寸(cun)均符合ISO6021/1-1981的(de)規定。活(huo)塞桿端(duan)螺紋亦符合GB2350-80的(de)規定。適用(yong)于(yu)工(gong)作(zuo)溫度為(wei)-30C~+80C，工(gong)作(zuo)介質為(wei)液(ye)(ye)壓(ya)(ya)油(you)，乳化液(ye)(ye)的(de)冶金(jin)設備(bei)（不適用(yong)于(yu)磷酸脂(zhi)）。
液壓缸(gang)結構基本上可以分為缸(gang)筒(tong)和(he)缸(gang)蓋、活塞和(he)活塞桿、密封(feng)裝(zhuang)置、緩(huan)沖(chong)裝(zhuang)置和(he)排(pai)氣裝(zhuang)置五(wu)個部分。今天威海(hai)力建小編著重(zhong)帶著大(da)家了解一下缸(gang)筒(tong)和(he)缸(gang)蓋。
缸筒(tong)和缸蓋(gai)
一般來說，缸(gang)(gang)筒(tong)和(he)(he)缸(gang)(gang)蓋的(de)結(jie)(jie)構形(xing)(xing)式(shi)(shi)(shi)和(he)(he)其使(shi)用(yong)(yong)的(de)材料有關。工(gong)(gong)(gong)作壓力p＜10MPa時(shi)(shi)，使(shi)用(yong)(yong)鑄(zhu)(zhu)鐵；p＜20MPa時(shi)(shi)，使(shi)用(yong)(yong)無(wu)縫(feng)鋼(gang)(gang)管(guan)；p＞20MPa時(shi)(shi)，使(shi)用(yong)(yong)鑄(zhu)(zhu)鋼(gang)(gang)或(huo)(huo)鍛(duan)鋼(gang)(gang)。法蘭連接(jie)(jie)式(shi)(shi)(shi)，結(jie)(jie)構簡單，容(rong)(rong)易加(jia)(jia)工(gong)(gong)(gong)，也容(rong)(rong)易裝(zhuang)(zhuang)拆，但(dan)(dan)外(wai)(wai)形(xing)(xing)尺寸和(he)(he)重量都較(jiao)大，常(chang)用(yong)(yong)于鑄(zhu)(zhu)鐵制(zhi)的(de)缸(gang)(gang)筒(tong)上(shang)。半環連接(jie)(jie)式(shi)(shi)(shi)，它(ta)的(de)缸(gang)(gang)筒(tong)壁部(bu)因開(kai)了環形(xing)(xing)槽而削弱了強度，為此有時(shi)(shi)要(yao)加(jia)(jia)厚缸(gang)(gang)壁，它(ta)容(rong)(rong)易加(jia)(jia)工(gong)(gong)(gong)和(he)(he)裝(zhuang)(zhuang)拆，重量較(jiao)輕(qing)，常(chang)用(yong)(yong)于無(wu)縫(feng)鋼(gang)(gang)管(guan)或(huo)(huo)鍛(duan)鋼(gang)(gang)制(zhi)的(de)缸(gang)(gang)筒(tong)上(shang)。螺紋連接(jie)(jie)式(shi)(shi)(shi)，它(ta)的(de)缸(gang)(gang)筒(tong)端(duan)部(bu)結(jie)(jie)構復雜，外(wai)(wai)徑(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)時(shi)(shi)要(yao)求(qiu)保證內(nei)外(wai)(wai)徑(jing)(jing)同心，裝(zhuang)(zhuang)拆要(yao)使(shi)用(yong)(yong)工(gong)(gong)(gong)具，它(ta)的(de)外(wai)(wai)形(xing)(xing)尺寸和(he)(he)重量都較(jiao)小，常(chang)用(yong)(yong)于無(wu)縫(feng)鋼(gang)(gang)管(guan)或(huo)(huo)鑄(zhu)(zhu)鋼(gang)(gang)制(zhi)的(de)缸(gang)(gang)筒(tong)上(shang)。拉桿連接(jie)(jie)式(shi)(shi)(shi)，結(jie)(jie)構的(de)通用(yong)(yong)性(xing)大，容(rong)(rong)易加(jia)(jia)工(gong)(gong)(gong)和(he)(he)裝(zhuang)(zhuang)拆，但(dan)(dan)外(wai)(wai)形(xing)(xing)尺寸較(jiao)大，且較(jiao)重。焊(han)接(jie)(jie)連接(jie)(jie)式(shi)(shi)(shi)，結(jie)(jie)構簡單，尺寸小，但(dan)(dan)缸(gang)(gang)底處內(nei)徑(jing)(jing)不易加(jia)(jia)工(gong)(gong)(gong)，且可能(neng)引(yin)起變形(xing)(xing)。
零(ling)部件(jian)加(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)的影響(xiang)問(wen)題，在液壓(ya)缸(gang)(gang)的制造過程中(zhong)應嚴格(ge)控制缸(gang)(gang)體(ti)內(nei)壁(bi)和活(huo)塞(sai)桿表(biao)面(mian)加(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)，特(te)別是幾何精(jing)度(du)，尤其直(zhi)線度(du)是關鍵(jian)，在國內(nei)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)(yi)中(zhong)，活(huo)塞(sai)桿表(biao)面(mian)的加(jia)(jia)工(gong)(gong)(gong)基(ji)本上是車后(hou)磨(mo)(mo)削(xue)(xue)(xue)，保證直(zhi)線度(du)問(wen)題不(bu)大(da)，但對于缸(gang)(gang)體(ti)內(nei)壁(bi)的加(jia)(jia)工(gong)(gong)(gong)，其加(jia)(jia)工(gong)(gong)(gong)方法很多，有鏜削(xue)(xue)(xue)-滾壓(ya)、鏜削(xue)(xue)(xue)-珩(heng)磨(mo)(mo)、直(zhi)接(jie)珩(heng)磨(mo)(mo)等，但由于國內(nei)材(cai)料(liao)(liao)的基(ji)礎水平較國外有差距，管材(cai)坯(pi)(pi)料(liao)(liao)直(zhi)線度(du)差，壁(bi)厚不(bu)均勻、硬度(du)不(bu)均勻等因(yin)素，往(wang)往(wang)直(zhi)接(jie)影響(xiang)缸(gang)(gang)體(ti)內(nei)壁(bi)加(jia)(jia)工(gong)(gong)(gong)后(hou)的直(zhi)線度(du)，因(yin)此建議采用鏜削(xue)(xue)(xue)-滾壓(ya)、鏜削(xue)(xue)(xue)-珩(heng)磨(mo)(mo)工(gong)(gong)(gong)藝(yi)(yi)，如直(zhi)接(jie)珩(heng)磨(mo)(mo)，則必須首先(xian)提高管材(cai)坯(pi)(pi)料(liao)(liao)的直(zhi)線度(du)。

在允許的情況(kuang)(kuang)下(xia)，液(ye)壓缸(gang)的缸(gang)體(ti)壁厚(hou)安(an)全系數盡量(liang)選大一些，使缸(gang)體(ti)厚(hou)壁增(zeng)加，特別(bie)是高壓工(gong)況(kuang)(kuang)下(xia)使用(yong)的油缸(gang)，以減小油壓下(xia)的缸(gang)體(ti)變(bian)形，變(bian)形后(hou)的缸(gang)體(ti)也(ye)會(hui)引起液(ye)壓缸(gang)低速爬(pa)行。
