擺動式液壓缸
擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)液壓缸是輸出扭矩并實現(xian)往(wang)復(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)執行(xing)元件，有單葉片、雙葉片、螺(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)等幾種形式(shi)(shi)。葉片式(shi)(shi)式(shi)(shi)：定子(zi)(zi)塊(kuai)固定在缸體上，而(er)葉片和轉(zhuan)子(zi)(zi)連接(jie)在一起。根(gen)據(ju)進油方向，葉片將帶動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)子(zi)(zi)作往(wang)復(fu)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)又分單螺(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)和雙螺(luo)旋(xuan)(xuan)兩(liang)種，現(xian)在雙螺(luo)旋(xuan)(xuan)比(bi)較常用(yong)，靠兩(liang)個螺(luo)旋(xuan)(xuan)副降(jiang)液壓缸內活塞的(de)直線運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)變為直線運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)復(fu)he運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，從而(er)實現(xian)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。
(1)閥(fa)(fa)芯(xin)卡住或(huo)(huo)(huo)閥(fa)(fa)孔(kong)堵塞。當流量閥(fa)(fa)或(huo)(huo)(huo)方(fang)向閥(fa)(fa)閥(fa)(fa)芯(xin)卡住或(huo)(huo)(huo)閥(fa)(fa)孔(kong)堵塞時，液(ye)壓缸(gang)易發生(sheng)誤動作或(huo)(huo)(huo)動作失靈。此時應檢(jian)查(cha)(cha)油(you)液(ye)的污染(ran)情(qing)況(kuang)；檢(jian)查(cha)(cha)臟物(wu)或(huo)(huo)(huo)膠質(zhi)(zhi)沉淀物(wu)是否卡住閥(fa)(fa)芯(xin)或(huo)(huo)(huo)堵塞閥(fa)(fa)孔(kong)；檢(jian)查(cha)(cha)閥(fa)(fa)體的磨損情(qing)況(kuang)，清(qing)洗、更換系統過濾器，清(qing)洗油(you)箱，更換液(ye)壓介質(zhi)(zhi)。
(2)活(huo)(huo)塞(sai)桿(gan)(gan)與缸(gang)筒(tong)卡住(zhu)或(huo)液壓缸(gang)堵塞(sai)。此時(shi)無論如何操縱，液壓缸(gang)都不動(dong)作或(huo)動(dong)作甚微。這時(shi)應檢查活(huo)(huo)塞(sai)及活(huo)(huo)塞(sai)桿(gan)(gan)密(mi)封(feng)是否(fou)太緊，是否(fou)進入臟物及膠質沉淀物：活(huo)(huo)塞(sai)桿(gan)(gan)與缸(gang)筒(tong)的軸(zhou)心線是否(fou)對中，易損件(jian)和密(mi)封(feng)件(jian)是否(fou)失效(xiao)，所(suo)帶(dai)負(fu)荷是否(fou)太大(da)。
這樣(yang)，活(huo)塞(sai)在液壓缸內工作時(shi)，摩擦阻力(li)會時(shi)大時(shi)小，產生(sheng)滑移(yi)或爬行。排除辦法是先修(xiu)(xiu)磨液壓缸，再按配合要求配制(zhi)活(huo)塞(sai)，修(xiu)(xiu)磨活(huo)塞(sai)桿，配置導向套(tao)。
(3)液(ye)壓泵或液(ye)壓缸進入空氣。空氣壓縮或膨脹會造成活塞滑移或爬行。排(pai)(pai)除措施是檢(jian)查液(ye)壓泵，設置專門(men)的排(pai)(pai)氣裝置，快(kuai)速操作全行程往返數(shu)次排(pai)(pai)氣。
(4)密封件質量與滑(hua)移或(huo)爬行(xing)有直接(jie)關系。
