擺動式液壓缸
擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)液壓缸(gang)是輸出(chu)扭矩并實現往(wang)復運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的執行元件，有單(dan)葉片(pian)、雙葉片(pian)、螺(luo)(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)等幾種形式(shi)(shi)。葉片(pian)式(shi)(shi)式(shi)(shi)：定子塊固定在(zai)缸(gang)體上(shang)，而葉片(pian)和轉子連接在(zai)一(yi)起。根據(ju)進油方向，葉片(pian)將帶動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉子作往(wang)復擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)又分單(dan)螺(luo)(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)和雙螺(luo)(luo)旋兩(liang)種，現在(zai)雙螺(luo)(luo)旋比較常(chang)用，靠兩(liang)個螺(luo)(luo)旋副降(jiang)液壓缸(gang)內活塞的直線運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉變為直線運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)與自轉運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的復he運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，從而實現擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。
(1)閥(fa)芯卡住或(huo)閥(fa)孔(kong)堵(du)塞(sai)。當流量閥(fa)或(huo)方(fang)向閥(fa)閥(fa)芯卡住或(huo)閥(fa)孔(kong)堵(du)塞(sai)時(shi)，液壓(ya)缸(gang)易發(fa)生誤動作(zuo)或(huo)動作(zuo)失(shi)靈。此時(shi)應檢(jian)查油液的污染(ran)情況；檢(jian)查臟物或(huo)膠質(zhi)沉(chen)淀物是否卡住閥(fa)芯或(huo)堵(du)塞(sai)閥(fa)孔(kong)；檢(jian)查閥(fa)體的磨損情況，清洗、更換(huan)系統過濾器，清洗油箱，更換(huan)液壓(ya)介質(zhi)。
(2)活塞桿(gan)與缸筒卡住(zhu)或液(ye)壓缸堵塞。此時無論如(ru)何操(cao)縱，液(ye)壓缸都不動(dong)作或動(dong)作甚微。這(zhe)時應檢查活塞及(ji)(ji)活塞桿(gan)密(mi)封是(shi)否(fou)太緊(jin)，是(shi)否(fou)進入臟物(wu)及(ji)(ji)膠質沉淀物(wu)：活塞桿(gan)與缸筒的(de)軸心線是(shi)否(fou)對中(zhong)，易損件(jian)和密(mi)封件(jian)是(shi)否(fou)失效，所帶負荷是(shi)否(fou)太大。
這樣，活塞在液(ye)壓(ya)缸內工(gong)作時(shi)(shi)，摩(mo)擦阻力會時(shi)(shi)大時(shi)(shi)小，產生(sheng)滑移或爬(pa)行(xing)。排除辦法是先修磨(mo)液(ye)壓(ya)缸，再按(an)配合要求配制活塞，修磨(mo)活塞桿(gan)，配置導向套。
(3)液壓(ya)(ya)泵(beng)或(huo)液壓(ya)(ya)缸進(jin)入空(kong)氣(qi)。空(kong)氣(qi)壓(ya)(ya)縮(suo)或(huo)膨(peng)脹會造(zao)成活塞滑移或(huo)爬行。排除措施是檢查液壓(ya)(ya)泵(beng)，設置(zhi)專門的排氣(qi)裝置(zhi)，快(kuai)速操作全行程往返數(shu)次排氣(qi)。
(4)密封件質量與滑移或(huo)爬行有(you)直接關系。
