擺動式液壓缸
擺動(dong)(dong)(dong)(dong)式液(ye)壓缸是輸出扭矩并實(shi)現往復運(yun)動(dong)(dong)(dong)(dong)的執行元(yuan)件(jian)，有單葉片、雙(shuang)葉片、螺(luo)(luo)旋擺動(dong)(dong)(dong)(dong)等(deng)幾種(zhong)形式。葉片式式：定子塊固(gu)定在缸體上，而葉片和(he)轉(zhuan)子連接在一起。根據進油方向，葉片將帶(dai)動(dong)(dong)(dong)(dong)轉(zhuan)子作往復擺動(dong)(dong)(dong)(dong)。螺(luo)(luo)旋擺動(dong)(dong)(dong)(dong)式又(you)分(fen)單螺(luo)(luo)旋擺動(dong)(dong)(dong)(dong)和(he)雙(shuang)螺(luo)(luo)旋兩種(zhong)，現在雙(shuang)螺(luo)(luo)旋比較常用(yong)，靠兩個螺(luo)(luo)旋副(fu)降(jiang)液(ye)壓缸內活塞(sai)的直線運(yun)動(dong)(dong)(dong)(dong)轉(zhuan)變為直線運(yun)動(dong)(dong)(dong)(dong)與自轉(zhuan)運(yun)動(dong)(dong)(dong)(dong)的復he運(yun)動(dong)(dong)(dong)(dong)，從而實(shi)現擺動(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)。
其(qi)次是裝(zhuang)配時有(you)異(yi)物(wu)進入(ru)及(ji)密封材料質量不好。其(qi)后果則是動作緩慢、無力，嚴重(zhong)時還(huan)會(hui)造成活(huo)塞及(ji)缸(gang)(gang)筒(tong)的(de)損壞(huai)，出現“拉(la)缸(gang)(gang)”現象。處理方法是調整速度控制閥，對照安裝(zhuang)說明應做必(bi)要的(de)操作和改(gai)進。
(2)液壓(ya)回路泄漏。包括(kuo)閥(fa)及液壓(ya)管路的泄漏。檢(jian)修方(fang)法是通過操(cao)縱(zong)換向(xiang)閥(fa)檢(jian)查并消除液壓(ya)連接管路的泄漏。
(3)液(ye)壓油經(jing)溢流(liu)閥旁通(tong)回油箱(xiang)。
液壓缸(gang)結構(gou)基本上可(ke)以分(fen)為缸(gang)筒(tong)和缸(gang)蓋、活塞和活塞桿(gan)、密封裝置(zhi)、緩(huan)沖裝置(zhi)和排氣裝置(zhi)五個(ge)部(bu)分(fen)。今(jin)天威海(hai)力建小(xiao)編著(zhu)重帶著(zhu)大家了解一(yi)下缸(gang)筒(tong)和缸(gang)蓋。
缸(gang)筒和缸(gang)蓋
一般來(lai)說，缸(gang)(gang)筒和缸(gang)(gang)蓋的(de)(de)(de)結構(gou)(gou)形(xing)(xing)式(shi)和其使(shi)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)材(cai)料有(you)關。工(gong)(gong)(gong)作壓力p＜10MPa時，使(shi)用(yong)(yong)(yong)(yong)(yong)鑄鐵(tie)；p＜20MPa時，使(shi)用(yong)(yong)(yong)(yong)(yong)無(wu)縫鋼(gang)(gang)管(guan)；p＞20MPa時，使(shi)用(yong)(yong)(yong)(yong)(yong)鑄鋼(gang)(gang)或鍛鋼(gang)(gang)。法蘭(lan)連(lian)(lian)接式(shi)，結構(gou)(gou)簡單，容易(yi)(yi)加工(gong)(gong)(gong)，也(ye)容易(yi)(yi)裝拆，但外(wai)形(xing)(xing)尺寸和重量(liang)都較(jiao)大，常用(yong)(yong)(yong)(yong)(yong)于鑄鐵(tie)制(zhi)(zhi)的(de)(de)(de)缸(gang)(gang)筒上(shang)(shang)。半環連(lian)(lian)接式(shi)，它的(de)(de)(de)缸(gang)(gang)筒壁(bi)部(bu)因開了環形(xing)(xing)槽而削弱了強度，為此(ci)有(you)時要(yao)加厚缸(gang)(gang)壁(bi)，它容易(yi)(yi)加工(gong)(gong)(gong)和裝拆，重量(liang)較(jiao)輕(qing)，常用(yong)(yong)(yong)(yong)(yong)于無(wu)縫鋼(gang)(gang)管(guan)或鍛鋼(gang)(gang)制(zhi)(zhi)的(de)(de)(de)缸(gang)(gang)筒上(shang)(shang)。螺紋連(lian)(lian)接式(shi)，它的(de)(de)(de)缸(gang)(gang)筒端(duan)部(bu)結構(gou)(gou)復雜，外(wai)徑(jing)加工(gong)(gong)(gong)時要(yao)求保證內外(wai)徑(jing)同(tong)心，裝拆要(yao)使(shi)用(yong)(yong)(yong)(yong)(yong)工(gong)(gong)(gong)具，它的(de)(de)(de)外(wai)形(xing)(xing)尺寸和重量(liang)都較(jiao)小(xiao)，常用(yong)(yong)(yong)(yong)(yong)于無(wu)縫鋼(gang)(gang)管(guan)或鑄鋼(gang)(gang)制(zhi)(zhi)的(de)(de)(de)缸(gang)(gang)筒上(shang)(shang)。拉桿連(lian)(lian)接式(shi)，結構(gou)(gou)的(de)(de)(de)通用(yong)(yong)(yong)(yong)(yong)性大，容易(yi)(yi)加工(gong)(gong)(gong)和裝拆，但外(wai)形(xing)(xing)尺寸較(jiao)大，且較(jiao)重。焊接連(lian)(lian)接式(shi)，結構(gou)(gou)簡單，尺寸小(xiao)，但缸(gang)(gang)底(di)處內徑(jing)不(bu)易(yi)(yi)加工(gong)(gong)(gong)，且可能(neng)引起變(bian)形(xing)(xing)。
