擺動式液壓缸

擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)液壓缸(gang)是輸出扭(niu)矩并實現往復運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的執(zhi)行元件，有單葉(xie)(xie)片(pian)(pian)(pian)、雙(shuang)(shuang)葉(xie)(xie)片(pian)(pian)(pian)、螺(luo)旋擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)幾種形式(shi)。葉(xie)(xie)片(pian)(pian)(pian)式(shi)式(shi)：定子塊固定在缸(gang)體上(shang)，而葉(xie)(xie)片(pian)(pian)(pian)和轉子連接在一起。根據(ju)進油方向(xiang)，葉(xie)(xie)片(pian)(pian)(pian)將(jiang)帶(dai)動(dong)(dong)(dong)(dong)(dong)(dong)轉子作往復擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)旋擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)又分單螺(luo)旋擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)和雙(shuang)(shuang)螺(luo)旋兩種，現在雙(shuang)(shuang)螺(luo)旋比較常用，靠兩個螺(luo)旋副降液壓缸(gang)內活塞(sai)的直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)轉變為直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)與自轉運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的復he運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)，從而實現擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)。

(1)閥芯卡住(zhu)或閥孔堵(du)塞(sai)。當流量閥或方向閥閥芯卡住(zhu)或閥孔堵(du)塞(sai)時，液壓(ya)缸易發生誤動(dong)作或動(dong)作失(shi)靈。此時應(ying)檢查油液的污染情況(kuang)；檢查臟物或膠質沉(chen)淀物是否(fou)卡住(zhu)閥芯或堵(du)塞(sai)閥孔；檢查閥體(ti)的磨損情況(kuang)，清洗、更(geng)換系統過濾器(qi)，清洗油箱，更(geng)換液壓(ya)介質。

(2)活塞(sai)桿與缸筒(tong)卡住或(huo)液(ye)壓(ya)缸堵塞(sai)。此(ci)時無論如何操縱，液(ye)壓(ya)缸都不動(dong)作或(huo)動(dong)作甚微。這時應(ying)檢查活塞(sai)及活塞(sai)桿密(mi)封(feng)是(shi)否(fou)(fou)(fou)太緊，是(shi)否(fou)(fou)(fou)進入臟物(wu)及膠質沉(chen)淀物(wu)：活塞(sai)桿與缸筒(tong)的軸心線(xian)是(shi)否(fou)(fou)(fou)對中(zhong)，易損件和密(mi)封(feng)件是(shi)否(fou)(fou)(fou)失效，所帶負(fu)荷是(shi)否(fou)(fou)(fou)太大(da)。

3、叉(cha)車叉(cha)架下降速度太快

故障檢查：節流(liu)閥卡在打開位置(zhi)或裝反

故障排(pai)除：重裝(zhuang)節流閥

4、叉車起升(sheng)缸自(zi)由下滑量太大(da)或傾斜缸自(zi)傾角太大(da)

故障(zhang)檢(jian)查：換向閥閥桿內(nei)泄漏(lou)太大，傾斜缸活塞密封(feng)圈(quan)失(shi)效內(nei)漏(lou)

故障排除：更(geng)換閥(fa)桿(gan)或(huo)更(geng)換密封圈

5、液壓缸活塞(sai)桿帶油

故障檢查：油封是(shi)否損(sun)壞

故障排除(chu)：更換油(you)封（威海力建冶金(jin)液壓設備廠(chang)推(tui)薦）
