液壓缸的分類
液壓缸的(de)結(jie)構形式(shi)(shi)(shi)(shi)多(duo)種多(duo)樣(yang)，其分(fen)(fen)(fen)類方(fang)法也有多(duo)種：按(an)運(yun)動方(fang)式(shi)(shi)(shi)(shi)可分(fen)(fen)(fen)為(wei)(wei)直線往(wang)復運(yun)動式(shi)(shi)(shi)(shi)和回轉擺(bai)動式(shi)(shi)(shi)(shi)；按(an)受液壓力作(zuo)用(yong)情(qing)況可分(fen)(fen)(fen)為(wei)(wei)單作(zuo)用(yong)式(shi)(shi)(shi)(shi)、雙作(zuo)用(yong)式(shi)(shi)(shi)(shi)；按(an)結(jie)構形式(shi)(shi)(shi)(shi)可分(fen)(fen)(fen)為(wei)(wei)活塞式(shi)(shi)(shi)(shi)、柱塞式(shi)(shi)(shi)(shi)、多(duo)級伸(shen)縮套筒式(shi)(shi)(shi)(shi)，齒(chi)輪齒(chi)條式(shi)(shi)(shi)(shi)等(deng)；按(an)安(an)裝形式(shi)(shi)(shi)(shi)可分(fen)(fen)(fen)為(wei)(wei)拉桿(gan)、耳環、底(di)腳、鉸(jiao)軸等(deng)；按(an)壓力等(deng)級可分(fen)(fen)(fen)為(wei)(wei)16Mpa、25Mpa、31.5Mpa等(deng)。（威海力建冶金液壓設備廠）
液(ye)壓缸(gang)結構(gou)基本上可以分為(wei)缸(gang)筒(tong)和缸(gang)蓋、活塞和活塞桿、密封裝置、緩沖裝置和排(pai)氣裝置五個部(bu)分。今天(tian)威海力建小編著重帶著大家了解一下缸(gang)筒(tong)和缸(gang)蓋。
缸筒和缸蓋(gai)
一(yi)般(ban)來(lai)說，缸(gang)筒(tong)(tong)(tong)和缸(gang)蓋的(de)(de)結(jie)(jie)構(gou)(gou)形式(shi)(shi)和其使(shi)用(yong)(yong)(yong)的(de)(de)材料有(you)關。工(gong)作(zuo)壓力p＜10MPa時，使(shi)用(yong)(yong)(yong)鑄鐵(tie)；p＜20MPa時，使(shi)用(yong)(yong)(yong)無縫鋼(gang)(gang)管(guan)；p＞20MPa時，使(shi)用(yong)(yong)(yong)鑄鋼(gang)(gang)或鍛鋼(gang)(gang)。法蘭連(lian)接(jie)式(shi)(shi)，結(jie)(jie)構(gou)(gou)簡(jian)單(dan)，容易加工(gong)，也容易裝(zhuang)拆，但(dan)外(wai)(wai)(wai)形尺(chi)(chi)寸和重(zhong)(zhong)量(liang)(liang)都較大，常(chang)(chang)用(yong)(yong)(yong)于鑄鐵(tie)制(zhi)的(de)(de)缸(gang)筒(tong)(tong)(tong)上(shang)。半環連(lian)接(jie)式(shi)(shi)，它的(de)(de)缸(gang)筒(tong)(tong)(tong)壁部(bu)因開了(le)環形槽(cao)而削弱了(le)強(qiang)度，為此有(you)時要加厚缸(gang)壁，它容易加工(gong)和裝(zhuang)拆，重(zhong)(zhong)量(liang)(liang)較輕，常(chang)(chang)用(yong)(yong)(yong)于無縫鋼(gang)(gang)管(guan)或鍛鋼(gang)(gang)制(zhi)的(de)(de)缸(gang)筒(tong)(tong)(tong)上(shang)。螺紋連(lian)接(jie)式(shi)(shi)，它的(de)(de)缸(gang)筒(tong)(tong)(tong)端部(bu)結(jie)(jie)構(gou)(gou)復雜(za)，外(wai)(wai)(wai)徑加工(gong)時要求保(bao)證內外(wai)(wai)(wai)徑同心，裝(zhuang)拆要使(shi)用(yong)(yong)(yong)工(gong)具，它的(de)(de)外(wai)(wai)(wai)形尺(chi)(chi)寸和重(zhong)(zhong)量(liang)(liang)都較小(xiao)，常(chang)(chang)用(yong)(yong)(yong)于無縫鋼(gang)(gang)管(guan)或鑄鋼(gang)(gang)制(zhi)的(de)(de)缸(gang)筒(tong)(tong)(tong)上(shang)。拉桿連(lian)接(jie)式(shi)(shi)，結(jie)(jie)構(gou)(gou)的(de)(de)通用(yong)(yong)(yong)性大，容易加工(gong)和裝(zhuang)拆，但(dan)外(wai)(wai)(wai)形尺(chi)(chi)寸較大，且較重(zhong)(zhong)。焊接(jie)連(lian)接(jie)式(shi)(shi)，結(jie)(jie)構(gou)(gou)簡(jian)單(dan)，尺(chi)(chi)寸小(xiao)，但(dan)缸(gang)底處內徑不易加工(gong)，且可能引起(qi)變形。
液壓缸泄漏帶來的危害很多，既是(shi)(shi)液壓缸產生各種(zhong)故障的原因之一，又是(shi)(shi)影響安全(quan)、污染環(huan)境的重要因素，所以應引起足夠的重視。
液壓(ya)缸(gang)的(de)(de)泄(xie)漏(lou)(lou)(lou)(lou)包(bao)括外(wai)泄(xie)漏(lou)(lou)(lou)(lou)和外(wai)泄(xie)漏(lou)(lou)(lou)(lou)兩種情況(kuang)。外(wai)泄(xie)漏(lou)(lou)(lou)(lou)是指(zhi)(zhi)液壓(ya)缸(gang)缸(gang)筒和缸(gang)蓋、缸(gang)底、油(you)口、排氣閥、緩沖調節(jie)閥、缸(gang)蓋與活塞(sai)(sai)桿處等外(wai)部(bu)的(de)(de)漏(lou)(lou)(lou)(lou)油(you)，容易(yi)從外(wai)部(bu)直接觀察出。內(nei)泄(xie)漏(lou)(lou)(lou)(lou)是指(zhi)(zhi)液壓(ya)缸(gang)內(nei)部(bu)高壓(ya)腔的(de)(de)壓(ya)力油(you)向低壓(ya)腔滲(shen)漏(lou)(lou)(lou)(lou)，它(ta)發生在活塞(sai)(sai)與缸(gang)內(nei)壁(bi)、活塞(sai)(sai)內(nei)孔與活塞(sai)(sai)桿連(lian)接處。內(nei)泄(xie)漏(lou)(lou)(lou)(lou)不(bu)能直接觀察到。不(bu)論(lun)是內(nei)泄(xie)漏(lou)(lou)(lou)(lou)和外(wai)泄(xie)漏(lou)(lou)(lou)(lou)，其泄(xie)漏(lou)(lou)(lou)(lou)的(de)(de)原因主要是密封不(bu)良、連(lian)接處接觸(chu)不(bu)良等。
