擺動式液壓缸
擺動(dong)(dong)(dong)式液(ye)壓缸(gang)是輸出(chu)扭矩并實(shi)現(xian)往復(fu)運(yun)(yun)動(dong)(dong)(dong)的(de)執行元件，有單葉(xie)(xie)片、雙葉(xie)(xie)片、螺(luo)(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)等幾種形式。葉(xie)(xie)片式式：定子塊固定在(zai)缸(gang)體(ti)上，而(er)葉(xie)(xie)片和轉(zhuan)(zhuan)子連接在(zai)一(yi)起(qi)。根據(ju)進油方向(xiang)，葉(xie)(xie)片將帶動(dong)(dong)(dong)轉(zhuan)(zhuan)子作往復(fu)擺動(dong)(dong)(dong)。螺(luo)(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)式又分單螺(luo)(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)和雙螺(luo)(luo)旋(xuan)(xuan)兩種，現(xian)在(zai)雙螺(luo)(luo)旋(xuan)(xuan)比較(jiao)常用，靠兩個螺(luo)(luo)旋(xuan)(xuan)副(fu)降液(ye)壓缸(gang)內活塞(sai)的(de)直(zhi)線運(yun)(yun)動(dong)(dong)(dong)轉(zhuan)(zhuan)變為直(zhi)線運(yun)(yun)動(dong)(dong)(dong)與自轉(zhuan)(zhuan)運(yun)(yun)動(dong)(dong)(dong)的(de)復(fu)he運(yun)(yun)動(dong)(dong)(dong)，從而(er)實(shi)現(xian)擺動(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)。
其(qi)次(ci)是裝配時有異物進入及密封材料質量不好(hao)。其(qi)后(hou)果則是動作(zuo)(zuo)緩慢、無力，嚴重時還會造成活塞(sai)及缸筒(tong)的(de)損壞(huai)，出現(xian)“拉缸”現(xian)象。處理方法(fa)是調(diao)整速度控(kong)制閥，對照安裝說明應做必要的(de)操作(zuo)(zuo)和改進。
(2)液(ye)壓(ya)回(hui)路泄漏。包括(kuo)閥及液(ye)壓(ya)管路的泄漏。檢修方(fang)法是(shi)通過操(cao)縱換向閥檢查并(bing)消除液(ye)壓(ya)連接管路的泄漏。
(3)液(ye)壓油(you)經溢流閥旁通(tong)回油(you)箱。
液壓缸(gang)(gang)結構基本上可以分為缸(gang)(gang)筒(tong)和缸(gang)(gang)蓋、活塞和活塞桿(gan)、密(mi)封裝(zhuang)置、緩沖裝(zhuang)置和排氣裝(zhuang)置五個(ge)部(bu)分。今(jin)天威海力建小編(bian)著重帶著大家了解一下缸(gang)(gang)筒(tong)和缸(gang)(gang)蓋。
缸筒和(he)缸蓋
一般來說(shuo)，缸(gang)筒(tong)和(he)缸(gang)蓋的(de)(de)(de)(de)結構(gou)形(xing)式和(he)其使(shi)(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)材(cai)料(liao)有關(guan)。工(gong)作壓力p＜10MPa時，使(shi)(shi)(shi)用(yong)(yong)(yong)鑄(zhu)(zhu)鐵(tie)；p＜20MPa時，使(shi)(shi)(shi)用(yong)(yong)(yong)無縫(feng)鋼(gang)(gang)管(guan)；p＞20MPa時，使(shi)(shi)(shi)用(yong)(yong)(yong)鑄(zhu)(zhu)鋼(gang)(gang)或鍛鋼(gang)(gang)。法蘭連(lian)(lian)接(jie)(jie)(jie)式，結構(gou)簡單(dan)，容(rong)易加(jia)(jia)工(gong)，也(ye)容(rong)易裝(zhuang)拆，但外(wai)形(xing)尺(chi)(chi)寸(cun)和(he)重(zhong)量(liang)都(dou)較(jiao)(jiao)大，常用(yong)(yong)(yong)于鑄(zhu)(zhu)鐵(tie)制(zhi)的(de)(de)(de)(de)缸(gang)筒(tong)上。半環連(lian)(lian)接(jie)(jie)(jie)式，它(ta)的(de)(de)(de)(de)缸(gang)筒(tong)壁(bi)(bi)部(bu)因開了環形(xing)槽而削弱了強度，為此有時要加(jia)(jia)厚缸(gang)壁(bi)(bi)，它(ta)容(rong)易加(jia)(jia)工(gong)和(he)裝(zhuang)拆，重(zhong)量(liang)較(jiao)(jiao)輕，常用(yong)(yong)(yong)于無縫(feng)鋼(gang)(gang)管(guan)或鍛鋼(gang)(gang)制(zhi)的(de)(de)(de)(de)缸(gang)筒(tong)上。螺紋(wen)連(lian)(lian)接(jie)(jie)(jie)式，它(ta)的(de)(de)(de)(de)缸(gang)筒(tong)端(duan)部(bu)結構(gou)復雜(za)，外(wai)徑(jing)加(jia)(jia)工(gong)時要求保證(zheng)內外(wai)徑(jing)同心，裝(zhuang)拆要使(shi)(shi)(shi)用(yong)(yong)(yong)工(gong)具(ju)，它(ta)的(de)(de)(de)(de)外(wai)形(xing)尺(chi)(chi)寸(cun)和(he)重(zhong)量(liang)都(dou)較(jiao)(jiao)小(xiao)，常用(yong)(yong)(yong)于無縫(feng)鋼(gang)(gang)管(guan)或鑄(zhu)(zhu)鋼(gang)(gang)制(zhi)的(de)(de)(de)(de)缸(gang)筒(tong)上。拉桿連(lian)(lian)接(jie)(jie)(jie)式，結構(gou)的(de)(de)(de)(de)通(tong)用(yong)(yong)(yong)性大，容(rong)易加(jia)(jia)工(gong)和(he)裝(zhuang)拆，但外(wai)形(xing)尺(chi)(chi)寸(cun)較(jiao)(jiao)大，且較(jiao)(jiao)重(zhong)。焊接(jie)(jie)(jie)連(lian)(lian)接(jie)(jie)(jie)式，結構(gou)簡單(dan)，尺(chi)(chi)寸(cun)小(xiao)，但缸(gang)底處內徑(jing)不易加(jia)(jia)工(gong)，且可能引(yin)起變(bian)形(xing)。
