擺動式液壓缸
擺(bai)(bai)動(dong)式(shi)液壓缸(gang)(gang)是(shi)輸(shu)出扭矩并(bing)實(shi)現往復運動(dong)的執行(xing)元件，有單葉(xie)片(pian)、雙葉(xie)片(pian)、螺旋擺(bai)(bai)動(dong)等幾(ji)種(zhong)形(xing)式(shi)。葉(xie)片(pian)式(shi)式(shi)：定(ding)子(zi)(zi)塊固(gu)定(ding)在缸(gang)(gang)體上(shang)，而(er)葉(xie)片(pian)和轉(zhuan)子(zi)(zi)連接在一起。根據(ju)進(jin)油方(fang)向，葉(xie)片(pian)將(jiang)帶動(dong)轉(zhuan)子(zi)(zi)作(zuo)往復擺(bai)(bai)動(dong)。螺旋擺(bai)(bai)動(dong)式(shi)又(you)分(fen)單螺旋擺(bai)(bai)動(dong)和雙螺旋兩種(zhong)，現在雙螺旋比(bi)較(jiao)常(chang)用，靠(kao)兩個螺旋副降液壓缸(gang)(gang)內活塞的直線運動(dong)轉(zhuan)變為直線運動(dong)與自轉(zhuan)運動(dong)的復he運動(dong)，從而(er)實(shi)現擺(bai)(bai)動(dong)運動(dong)。
其(qi)次是裝配(pei)時有異物進入(ru)及密封材料質(zhi)量不好。其(qi)后果(guo)則是動作(zuo)緩慢、無力，嚴(yan)重時還會造(zao)成(cheng)活塞及缸筒(tong)的損壞，出現“拉缸”現象。處理方法是調整速度控制(zhi)閥，對照安裝說(shuo)明應做必(bi)要(yao)的操作(zuo)和改進。
(2)液(ye)(ye)壓回(hui)路泄(xie)漏(lou)。包(bao)括閥及液(ye)(ye)壓管(guan)路的(de)泄(xie)漏(lou)。檢修方(fang)法是通過操(cao)縱換向閥檢查(cha)并消除液(ye)(ye)壓連接(jie)管(guan)路的(de)泄(xie)漏(lou)。
(3)液(ye)壓油經溢流(liu)閥旁通回油箱。
液壓缸(gang)(gang)結構基本上可(ke)以分(fen)(fen)為缸(gang)(gang)筒和(he)缸(gang)(gang)蓋、活塞和(he)活塞桿、密封(feng)裝置(zhi)、緩沖裝置(zhi)和(he)排氣裝置(zhi)五個部分(fen)(fen)。今天(tian)威海力建小編著(zhu)重帶著(zhu)大家了解一下缸(gang)(gang)筒和(he)缸(gang)(gang)蓋。
缸(gang)筒和缸(gang)蓋
一般來說，缸(gang)筒(tong)(tong)和缸(gang)蓋(gai)的結(jie)構(gou)(gou)形(xing)式(shi)(shi)和其(qi)使(shi)用(yong)(yong)的材料有關。工(gong)(gong)作壓力p＜10MPa時，使(shi)用(yong)(yong)鑄(zhu)(zhu)鐵；p＜20MPa時，使(shi)用(yong)(yong)無縫鋼(gang)管；p＞20MPa時，使(shi)用(yong)(yong)鑄(zhu)(zhu)鋼(gang)或(huo)鍛鋼(gang)。法蘭連接式(shi)(shi)，結(jie)構(gou)(gou)簡(jian)單(dan)，容(rong)(rong)(rong)易(yi)加(jia)工(gong)(gong)，也容(rong)(rong)(rong)易(yi)裝(zhuang)(zhuang)拆，但(dan)外形(xing)尺寸(cun)(cun)(cun)和重(zhong)(zhong)量都較(jiao)(jiao)大(da)，常(chang)用(yong)(yong)于(yu)鑄(zhu)(zhu)鐵制(zhi)的缸(gang)筒(tong)(tong)上。半環(huan)連接式(shi)(shi)，它的缸(gang)筒(tong)(tong)壁(bi)部(bu)因開了環(huan)形(xing)槽而削(xue)弱(ruo)了強度(du)，為(wei)此(ci)有時要(yao)加(jia)厚缸(gang)壁(bi)，它容(rong)(rong)(rong)易(yi)加(jia)工(gong)(gong)和裝(zhuang)(zhuang)拆，重(zhong)(zhong)量較(jiao)(jiao)輕，常(chang)用(yong)(yong)于(yu)無縫鋼(gang)管或(huo)鍛鋼(gang)制(zhi)的缸(gang)筒(tong)(tong)上。螺紋連接式(shi)(shi)，它的缸(gang)筒(tong)(tong)端部(bu)結(jie)構(gou)(gou)復雜，外徑加(jia)工(gong)(gong)時要(yao)求保證(zheng)內外徑同心(xin)，裝(zhuang)(zhuang)拆要(yao)使(shi)用(yong)(yong)工(gong)(gong)具(ju)，它的外形(xing)尺寸(cun)(cun)(cun)和重(zhong)(zhong)量都較(jiao)(jiao)小，常(chang)用(yong)(yong)于(yu)無縫鋼(gang)管或(huo)鑄(zhu)(zhu)鋼(gang)制(zhi)的缸(gang)筒(tong)(tong)上。拉桿連接式(shi)(shi)，結(jie)構(gou)(gou)的通用(yong)(yong)性大(da)，容(rong)(rong)(rong)易(yi)加(jia)工(gong)(gong)和裝(zhuang)(zhuang)拆，但(dan)外形(xing)尺寸(cun)(cun)(cun)較(jiao)(jiao)大(da)，且(qie)較(jiao)(jiao)重(zhong)(zhong)。焊接連接式(shi)(shi)，結(jie)構(gou)(gou)簡(jian)單(dan)，尺寸(cun)(cun)(cun)小，但(dan)缸(gang)底處內徑不易(yi)加(jia)工(gong)(gong)，且(qie)可能引起變形(xing)。
