擺動式液壓缸
擺動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)液(ye)壓缸(gang)(gang)是輸出(chu)扭矩并實現往復(fu)運動(dong)(dong)(dong)(dong)(dong)的(de)執行元件，有單(dan)葉(xie)片(pian)(pian)(pian)、雙(shuang)葉(xie)片(pian)(pian)(pian)、螺旋擺動(dong)(dong)(dong)(dong)(dong)等(deng)幾種(zhong)形式(shi)(shi)。葉(xie)片(pian)(pian)(pian)式(shi)(shi)式(shi)(shi)：定(ding)子(zi)(zi)塊固定(ding)在缸(gang)(gang)體上，而(er)(er)葉(xie)片(pian)(pian)(pian)和轉(zhuan)子(zi)(zi)連接(jie)在一(yi)起。根據進油方(fang)向，葉(xie)片(pian)(pian)(pian)將帶動(dong)(dong)(dong)(dong)(dong)轉(zhuan)子(zi)(zi)作往復(fu)擺動(dong)(dong)(dong)(dong)(dong)。螺旋擺動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)又分單(dan)螺旋擺動(dong)(dong)(dong)(dong)(dong)和雙(shuang)螺旋兩(liang)種(zhong)，現在雙(shuang)螺旋比較常(chang)用，靠兩(liang)個(ge)螺旋副降液(ye)壓缸(gang)(gang)內活塞的(de)直線運動(dong)(dong)(dong)(dong)(dong)轉(zhuan)變為(wei)直線運動(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)運動(dong)(dong)(dong)(dong)(dong)的(de)復(fu)he運動(dong)(dong)(dong)(dong)(dong)，從(cong)而(er)(er)實現擺動(dong)(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)(dong)。
其(qi)次是(shi)(shi)裝配時有異物進入及密(mi)封材料質量不好(hao)。其(qi)后果則(ze)是(shi)(shi)動作緩慢、無力，嚴重(zhong)時還會造成活塞及缸(gang)筒的損(sun)壞(huai)，出現(xian)“拉缸(gang)”現(xian)象。處(chu)理方法是(shi)(shi)調整速(su)度控制閥，對照安裝說明應做必要的操作和改進。
(2)液壓回(hui)路泄(xie)(xie)漏(lou)。包括閥(fa)及(ji)液壓管路的(de)泄(xie)(xie)漏(lou)。檢(jian)修方法是(shi)通過操縱換向閥(fa)檢(jian)查并消除液壓連接管路的(de)泄(xie)(xie)漏(lou)。
(3)液(ye)壓油經溢流(liu)閥旁通回油箱。
液壓缸結(jie)構基本上可以分為缸筒(tong)和缸蓋(gai)、活塞和活塞桿、密封裝置(zhi)、緩沖(chong)裝置(zhi)和排氣裝置(zhi)五(wu)個部分。今天威海力建(jian)小編著(zhu)重帶(dai)著(zhu)大家(jia)了解一下缸筒(tong)和缸蓋(gai)。
缸筒(tong)和(he)缸蓋
一(yi)般來說，缸(gang)筒(tong)和(he)缸(gang)蓋的結(jie)構(gou)(gou)(gou)形(xing)式(shi)和(he)其使(shi)用(yong)(yong)的材(cai)料有關。工(gong)(gong)作壓力p＜10MPa時(shi)，使(shi)用(yong)(yong)鑄鐵；p＜20MPa時(shi)，使(shi)用(yong)(yong)無縫(feng)鋼(gang)管；p＞20MPa時(shi)，使(shi)用(yong)(yong)鑄鋼(gang)或鍛鋼(gang)。法蘭連(lian)接式(shi)，結(jie)構(gou)(gou)(gou)簡單(dan)，容(rong)易(yi)加(jia)工(gong)(gong)，也容(rong)易(yi)裝(zhuang)(zhuang)拆(chai)(chai)，但(dan)外(wai)形(xing)尺寸和(he)重(zhong)量都較大，常用(yong)(yong)于鑄鐵制(zhi)(zhi)(zhi)的缸(gang)筒(tong)上(shang)。半環連(lian)接式(shi)，它(ta)的缸(gang)筒(tong)壁部(bu)因開了環形(xing)槽而削(xue)弱了強度，為(wei)此(ci)有時(shi)要加(jia)厚缸(gang)壁，它(ta)容(rong)易(yi)加(jia)工(gong)(gong)和(he)裝(zhuang)(zhuang)拆(chai)(chai)，重(zhong)量較輕，常用(yong)(yong)于無縫(feng)鋼(gang)管或鍛鋼(gang)制(zhi)(zhi)(zhi)的缸(gang)筒(tong)上(shang)。螺紋連(lian)接式(shi)，它(ta)的缸(gang)筒(tong)端部(bu)結(jie)構(gou)(gou)(gou)復雜，外(wai)徑加(jia)工(gong)(gong)時(shi)要求保證內(nei)外(wai)徑同心，裝(zhuang)(zhuang)拆(chai)(chai)要使(shi)用(yong)(yong)工(gong)(gong)具，它(ta)的外(wai)形(xing)尺寸和(he)重(zhong)量都較小，常用(yong)(yong)于無縫(feng)鋼(gang)管或鑄鋼(gang)制(zhi)(zhi)(zhi)的缸(gang)筒(tong)上(shang)。拉桿連(lian)接式(shi)，結(jie)構(gou)(gou)(gou)的通用(yong)(yong)性大，容(rong)易(yi)加(jia)工(gong)(gong)和(he)裝(zhuang)(zhuang)拆(chai)(chai)，但(dan)外(wai)形(xing)尺寸較大，且(qie)較重(zhong)。焊接連(lian)接式(shi)，結(jie)構(gou)(gou)(gou)簡單(dan)，尺寸小，但(dan)缸(gang)底處內(nei)徑不(bu)易(yi)加(jia)工(gong)(gong)，且(qie)可能引起變形(xing)。
