威海力建(jian)冶(ye)金液(ye)(ye)壓(ya)(ya)(ya)設(she)備(bei)廠座落在膠東半島美麗的海濱城市----威海，主要生產重載(zai)液(ye)(ye)壓(ya)(ya)(ya)缸(gang)、標準(zhun)液(ye)(ye)壓(ya)(ya)(ya)缸(gang)、工程液(ye)(ye)壓(ya)(ya)(ya)缸(gang)、車輛液(ye)(ye)壓(ya)(ya)(ya)缸(gang)、拉桿多(duo)液(ye)(ye)壓(ya)(ya)(ya)缸(gang)、液(ye)(ye)壓(ya)(ya)(ya)系統等系列多(duo)種(zhong)規(gui)格設(she)備(bei)及(ji)液(ye)(ye)壓(ya)(ya)(ya)元件。可以根據用(yong)戶需要設(she)計制造(zao)(zao)各種(zhong)工程用(yong)、冶(ye)金用(yong)標準(zhun)和非標準(zhun)液(ye)(ye)壓(ya)(ya)(ya)（氣）缸(gang)及(ji)冶(ye)金、礦(kuang)山、化工、交通等行業用(yong)液(ye)(ye)壓(ya)(ya)(ya)系統。同時還從(cong)事特種(zhong)鑄(zhu)造(zao)(zao)設(she)備(bei)（離(li)心(xin)鑄(zhu)造(zao)(zao)機、低壓(ya)(ya)(ya)鑄(zhu)造(zao)(zao)機）的研發﹑設(she)計、制造(zao)(zao)及(ji)安裝調試和咨(zi)詢服務。
液(ye)壓缸(gang)結構基本上可以分為缸(gang)筒和缸(gang)蓋、活塞(sai)和活塞(sai)桿、密封裝置、緩(huan)沖裝置和排氣(qi)裝置五個部分。今天威海力建小(xiao)編著重帶著大家了(le)解一下缸(gang)筒和缸(gang)蓋。
缸筒和缸蓋
一般來(lai)說，缸(gang)(gang)(gang)(gang)筒和(he)(he)缸(gang)(gang)(gang)(gang)蓋的(de)(de)(de)結(jie)構(gou)形(xing)(xing)式(shi)和(he)(he)其(qi)使(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)材料有(you)(you)關。工(gong)(gong)(gong)作壓力p＜10MPa時(shi)(shi)，使(shi)(shi)用(yong)(yong)(yong)鑄(zhu)(zhu)鐵；p＜20MPa時(shi)(shi)，使(shi)(shi)用(yong)(yong)(yong)無(wu)縫(feng)鋼管；p＞20MPa時(shi)(shi)，使(shi)(shi)用(yong)(yong)(yong)鑄(zhu)(zhu)鋼或(huo)鍛鋼。法(fa)蘭連接式(shi)，結(jie)構(gou)簡單，容(rong)(rong)易(yi)加工(gong)(gong)(gong)，也容(rong)(rong)易(yi)裝(zhuang)拆(chai)，但(dan)外(wai)形(xing)(xing)尺(chi)寸(cun)和(he)(he)重(zhong)(zhong)量都較大(da)，常(chang)用(yong)(yong)(yong)于(yu)鑄(zhu)(zhu)鐵制(zhi)的(de)(de)(de)缸(gang)(gang)(gang)(gang)筒上(shang)。半(ban)環(huan)連接式(shi)，它(ta)的(de)(de)(de)缸(gang)(gang)(gang)(gang)筒壁(bi)部因開了(le)環(huan)形(xing)(xing)槽而削(xue)弱了(le)強度，為(wei)此(ci)有(you)(you)時(shi)(shi)要加厚(hou)缸(gang)(gang)(gang)(gang)壁(bi)，它(ta)容(rong)(rong)易(yi)加工(gong)(gong)(gong)和(he)(he)裝(zhuang)拆(chai)，重(zhong)(zhong)量較輕，常(chang)用(yong)(yong)(yong)于(yu)無(wu)縫(feng)鋼管或(huo)鍛鋼制(zhi)的(de)(de)(de)缸(gang)(gang)(gang)(gang)筒上(shang)。螺紋連接式(shi)，它(ta)的(de)(de)(de)缸(gang)(gang)(gang)(gang)筒端部結(jie)構(gou)復雜，外(wai)徑(jing)加工(gong)(gong)(gong)時(shi)(shi)要求保證(zheng)內外(wai)徑(jing)同心，裝(zhuang)拆(chai)要使(shi)(shi)用(yong)(yong)(yong)工(gong)(gong)(gong)具，它(ta)的(de)(de)(de)外(wai)形(xing)(xing)尺(chi)寸(cun)和(he)(he)重(zhong)(zhong)量都較小，常(chang)用(yong)(yong)(yong)于(yu)無(wu)縫(feng)鋼管或(huo)鑄(zhu)(zhu)鋼制(zhi)的(de)(de)(de)缸(gang)(gang)(gang)(gang)筒上(shang)。拉桿連接式(shi)，結(jie)構(gou)的(de)(de)(de)通用(yong)(yong)(yong)性大(da)，容(rong)(rong)易(yi)加工(gong)(gong)(gong)和(he)(he)裝(zhuang)拆(chai)，但(dan)外(wai)形(xing)(xing)尺(chi)寸(cun)較大(da)，且(qie)較重(zhong)(zhong)。焊接連接式(shi)，結(jie)構(gou)簡單，尺(chi)寸(cun)小，但(dan)缸(gang)(gang)(gang)(gang)底處內徑(jing)不易(yi)加工(gong)(gong)(gong)，且(qie)可(ke)能(neng)引起(qi)變形(xing)(xing)。
線形、帶(dai)形密(mi)(mi)封(feng)材料的纏繞方(fang)法如果不對，密(mi)(mi)封(feng)帶(dai)將(jiang)被切斷，隨著(zhu)進(jin)入缸內。線帶(dai)形密(mi)(mi)封(feng)件對滑(hua)動(dong)部分的繞接(jie)不會造成什么影響(xiang)，但是會引(yin)起缸的單(dan)向閥(fa)動(dong)作不靈(ling)或造成緩(huan)沖調節(jie)閥(fa)不能(neng)調到底；對回(hui)路(lu)來說，可能(neng)引(yin)起換向閥(fa)、溢(yi)流(liu)閥(fa)和減壓(ya)閥(fa)的動(dong)作失靈(ling)。
傳(chuan)統的修(xiu)復方法是(shi)將損壞的部件(jian)進(jin)(jin)行拆卸后的外協修(xiu)復，或是(shi)進(jin)(jin)行刷鍍或是(shi)進(jin)(jin)行表面的整體刮(gua)研，修(xiu)復周期液壓(ya)缸缸體劃(hua)傷(shang)修(xiu)復長(chang)，修(xiu)復費用(yong)高。
