擺動式液壓缸
擺動(dong)(dong)(dong)式(shi)液(ye)壓缸(gang)是(shi)輸出扭矩(ju)并實現(xian)往(wang)復運(yun)(yun)(yun)動(dong)(dong)(dong)的執行元件，有(you)單(dan)葉(xie)片(pian)(pian)(pian)、雙(shuang)葉(xie)片(pian)(pian)(pian)、螺(luo)(luo)旋擺動(dong)(dong)(dong)等幾種形式(shi)。葉(xie)片(pian)(pian)(pian)式(shi)式(shi)：定子(zi)塊固(gu)定在(zai)缸(gang)體(ti)上，而(er)葉(xie)片(pian)(pian)(pian)和轉子(zi)連接在(zai)一起(qi)。根據(ju)進油方向，葉(xie)片(pian)(pian)(pian)將帶動(dong)(dong)(dong)轉子(zi)作往(wang)復擺動(dong)(dong)(dong)。螺(luo)(luo)旋擺動(dong)(dong)(dong)式(shi)又(you)分(fen)單(dan)螺(luo)(luo)旋擺動(dong)(dong)(dong)和雙(shuang)螺(luo)(luo)旋兩種，現(xian)在(zai)雙(shuang)螺(luo)(luo)旋比較常用，靠兩個螺(luo)(luo)旋副(fu)降液(ye)壓缸(gang)內活塞的直(zhi)線運(yun)(yun)(yun)動(dong)(dong)(dong)轉變為(wei)直(zhi)線運(yun)(yun)(yun)動(dong)(dong)(dong)與自轉運(yun)(yun)(yun)動(dong)(dong)(dong)的復he運(yun)(yun)(yun)動(dong)(dong)(dong)，從而(er)實現(xian)擺動(dong)(dong)(dong)運(yun)(yun)(yun)動(dong)(dong)(dong)。
其(qi)(qi)次是(shi)裝(zhuang)配時(shi)有異物進入(ru)及密封(feng)材料質量不(bu)好(hao)。其(qi)(qi)后果則是(shi)動作緩慢、無力(li)，嚴重時(shi)還會造成活(huo)塞及缸筒(tong)的損(sun)壞，出現“拉缸”現象(xiang)。處理方法是(shi)調整速(su)度控(kong)制閥，對(dui)照安裝(zhuang)說明(ming)應做必要(yao)的操作和改進。
(2)液壓(ya)回路泄漏。包括閥及液壓(ya)管(guan)路的泄漏。檢(jian)修方法是通(tong)過操縱換向閥檢(jian)查并消除液壓(ya)連接管(guan)路的泄漏。
(3)液壓油經溢流閥旁通回(hui)油箱。
液壓缸(gang)結構基本上可以分為缸(gang)筒(tong)(tong)和(he)缸(gang)蓋(gai)、活塞(sai)(sai)和(he)活塞(sai)(sai)桿、密封裝置、緩沖裝置和(he)排(pai)氣裝置五個部分。今天(tian)威海力(li)建小編著重帶著大(da)家了解一下缸(gang)筒(tong)(tong)和(he)缸(gang)蓋(gai)。
缸(gang)筒和缸(gang)蓋
一般來(lai)說，缸(gang)筒(tong)(tong)和(he)缸(gang)蓋(gai)的(de)(de)(de)結(jie)(jie)構形(xing)式(shi)和(he)其(qi)使(shi)(shi)用的(de)(de)(de)材(cai)料有(you)關。工(gong)(gong)作壓力(li)p＜10MPa時，使(shi)(shi)用鑄鐵(tie)；p＜20MPa時，使(shi)(shi)用無(wu)縫(feng)(feng)鋼管(guan)(guan)；p＞20MPa時，使(shi)(shi)用鑄鋼或鍛鋼。法蘭連(lian)接(jie)式(shi)，結(jie)(jie)構簡單(dan)，容(rong)易(yi)加(jia)(jia)工(gong)(gong)，也容(rong)易(yi)裝(zhuang)拆，但(dan)外(wai)(wai)形(xing)尺(chi)寸(cun)和(he)重(zhong)(zhong)量(liang)都較大(da)(da)，常用于(yu)鑄鐵(tie)制的(de)(de)(de)缸(gang)筒(tong)(tong)上。半環(huan)連(lian)接(jie)式(shi)，它(ta)的(de)(de)(de)缸(gang)筒(tong)(tong)壁(bi)部因開了環(huan)形(xing)槽(cao)而削弱了強度，為此有(you)時要(yao)加(jia)(jia)厚缸(gang)壁(bi)，它(ta)容(rong)易(yi)加(jia)(jia)工(gong)(gong)和(he)裝(zhuang)拆，重(zhong)(zhong)量(liang)較輕，常用于(yu)無(wu)縫(feng)(feng)鋼管(guan)(guan)或鍛鋼制的(de)(de)(de)缸(gang)筒(tong)(tong)上。螺紋連(lian)接(jie)式(shi)，它(ta)的(de)(de)(de)缸(gang)筒(tong)(tong)端部結(jie)(jie)構復雜，外(wai)(wai)徑(jing)加(jia)(jia)工(gong)(gong)時要(yao)求保證內外(wai)(wai)徑(jing)同心，裝(zhuang)拆要(yao)使(shi)(shi)用工(gong)(gong)具，它(ta)的(de)(de)(de)外(wai)(wai)形(xing)尺(chi)寸(cun)和(he)重(zhong)(zhong)量(liang)都較小，常用于(yu)無(wu)縫(feng)(feng)鋼管(guan)(guan)或鑄鋼制的(de)(de)(de)缸(gang)筒(tong)(tong)上。拉(la)桿連(lian)接(jie)式(shi)，結(jie)(jie)構的(de)(de)(de)通(tong)用性(xing)大(da)(da)，容(rong)易(yi)加(jia)(jia)工(gong)(gong)和(he)裝(zhuang)拆，但(dan)外(wai)(wai)形(xing)尺(chi)寸(cun)較大(da)(da)，且較重(zhong)(zhong)。焊接(jie)連(lian)接(jie)式(shi)，結(jie)(jie)構簡單(dan)，尺(chi)寸(cun)小，但(dan)缸(gang)底處內徑(jing)不(bu)易(yi)加(jia)(jia)工(gong)(gong)，且可能引起變形(xing)。
