伸縮式液壓缸
伸縮式液壓缸(gang)(gang)具有二級(ji)或(huo)多(duo)級(ji)活(huo)(huo)塞(sai)，伸縮式液壓缸(gang)(gang)中活(huo)(huo)塞(sai)伸出(chu)(chu)的(de)順(shun)序式從大到小，而空載縮回的(de)順(shun)序則一般是(shi)從小到大。伸縮缸(gang)(gang)可實現較(jiao)長(chang)的(de)行程，而縮回時長(chang)度(du)較(jiao)短，結構(gou)較(jiao)為緊湊(cou)。此種液壓缸(gang)(gang)常用于工程機(ji)械和(he)農(nong)業(ye)機(ji)械上。有多(duo)個一次(ci)運動(dong)(dong)的(de)活(huo)(huo)塞(sai)，各活(huo)(huo)塞(sai)逐次(ci)運動(dong)(dong)時，其(qi)輸出(chu)(chu)速度(du)和(he)輸出(chu)(chu)力(li)均是(shi)變化(hua)的(de)。(威海力(li)建冶金液壓設備廠)
擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)液壓(ya)缸(gang)(gang)是輸出(chu)扭(niu)矩并實現往(wang)復(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)的執行(xing)元件，有單葉(xie)片(pian)、雙葉(xie)片(pian)、螺(luo)(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)等幾(ji)種形式(shi)。葉(xie)片(pian)式(shi)式(shi)：定(ding)子(zi)塊固定(ding)在缸(gang)(gang)體上，而葉(xie)片(pian)和轉子(zi)連(lian)接(jie)在一(yi)起。根據進(jin)油方向，葉(xie)片(pian)將帶動(dong)(dong)(dong)(dong)(dong)轉子(zi)作往(wang)復(fu)擺(bai)動(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)又分單螺(luo)(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)和雙螺(luo)(luo)旋(xuan)兩(liang)(liang)種，現在雙螺(luo)(luo)旋(xuan)比較常用，靠兩(liang)(liang)個螺(luo)(luo)旋(xuan)副降液壓(ya)缸(gang)(gang)內活塞(sai)的直線運(yun)動(dong)(dong)(dong)(dong)(dong)轉變(bian)為直線運(yun)動(dong)(dong)(dong)(dong)(dong)與自轉運(yun)動(dong)(dong)(dong)(dong)(dong)的復(fu)he運(yun)動(dong)(dong)(dong)(dong)(dong)，從而實現擺(bai)動(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)。
例如(ru)：活(huo)塞與活(huo)塞桿不同心或活(huo)塞桿彎(wan)曲(qu)，液壓缸或活(huo)塞桿對導軌安裝(zhuang)位置偏移，密封環裝(zhuang)得過(guo)緊或過(guo)松等。解決方法是重新修理或調整，更換損(sun)傷的零件及清除(chu)鐵屑。
(2)潤(run)滑不良或液(ye)壓缸(gang)(gang)孔徑(jing)加(jia)工超差。因為活塞與缸(gang)(gang)筒(tong)、導軌(gui)與活塞桿等均有(you)相對運動，如果潤(run)滑不良或液(ye)壓缸(gang)(gang)孔徑(jing)超差，就會(hui)加(jia)劇磨損，使(shi)缸(gang)(gang)筒(tong)中心線直線性降低。（威(wei)海力建冶金(jin)液(ye)壓設備廠)
