擺動式液壓缸

擺(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)液壓缸(gang)(gang)是(shi)輸出扭矩并實現(xian)往(wang)復(fu)運動(dong)(dong)(dong)(dong)的(de)執(zhi)行元(yuan)件，有單葉(xie)(xie)片、雙(shuang)(shuang)葉(xie)(xie)片、螺(luo)(luo)(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)等(deng)幾種形式(shi)。葉(xie)(xie)片式(shi)式(shi)：定子塊固定在(zai)缸(gang)(gang)體(ti)上(shang)，而葉(xie)(xie)片和轉子連接在(zai)一起。根據進油方向，葉(xie)(xie)片將帶(dai)動(dong)(dong)(dong)(dong)轉子作往(wang)復(fu)擺(bai)(bai)動(dong)(dong)(dong)(dong)。螺(luo)(luo)(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)又分單螺(luo)(luo)(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)和雙(shuang)(shuang)螺(luo)(luo)(luo)旋(xuan)兩種，現(xian)在(zai)雙(shuang)(shuang)螺(luo)(luo)(luo)旋(xuan)比(bi)較常用，靠兩個螺(luo)(luo)(luo)旋(xuan)副降液壓缸(gang)(gang)內(nei)活塞(sai)的(de)直線(xian)運動(dong)(dong)(dong)(dong)轉變為直線(xian)運動(dong)(dong)(dong)(dong)與自轉運動(dong)(dong)(dong)(dong)的(de)復(fu)he運動(dong)(dong)(dong)(dong)，從而實現(xian)擺(bai)(bai)動(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)。

① 裝(zhuang)配時(shi)混(hun)入異(yi)物(wu)造(zao)成傷痕液壓缸在總(zong)組裝(zhuang)前(qian)，所有零(ling)(ling)件(jian)必須充分去除毛(mao)刺(ci)并洗凈， 零(ling)(ling)件(jian)上帶有毛(mao)刺(ci)或臟物(wu)進行安裝(zhuang)時(shi)，由(you)于'別勁(jing)'及(ji)零(ling)(ling)件(jian)自重，異(yi)物(wu)易嵌(qian)進缸壁(bi)表面，造(zao)成傷痕。

② 安裝零件(jian)中(zhong)發生(sheng)的傷(shang)痕液(ye)壓缸安裝時(shi)，活塞及缸蓋等零件(jian)質(zhi)量(liang)大(da)(da)、尺寸大(da)(da)、慣性大(da)(da)，即使有起(qi)重設備輔助(zhu)安裝，由于規定配(pei)合間隙都(dou)較小，無論怎樣均會別(bie)勁投(tou)入(ru)，

叉車起(qi)升缸活(huo)塞桿動作慢、起(qi)升時(shi)門(men)架有間斷或沖(chong)擊

故障檢查1：系統油(you)量不(bu)足

故障排除(chu)：加油(you)至油(you)標線

故障檢查(cha)2：密封不良、油(you)(you)管(guan)連(lian)接不緊造成漏油(you)(you)、油(you)(you)管(guan)損壞

故障(zhang)排除：加(jia)密封，擰緊管接頭，更換油管

故障檢(jian)查(cha)3：油泵故障致供油不足

故障排除：修理或更(geng)換油泵

故障檢查4：安全閥(fa)調整(zheng)不當或(huo)損壞(huai)

故障排除：調整或修理安全閥

故障檢查5：液壓過(guo)濾器堵(du)塞

故障排除(chu)：清洗或(huo)更換(huan)液壓油濾清器

故(gu)障檢(jian)查6：液(ye)壓系統中(zhong)有空氣(qi)

故(gu)障(zhang)排除：將空(kong)氣排除
