擺動式液壓缸
擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式液壓缸是輸出扭矩(ju)并實現往復運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)執(zhi)行元件，有單(dan)葉片(pian)、雙(shuang)葉片(pian)、螺(luo)(luo)旋(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)等幾種(zhong)(zhong)形式。葉片(pian)式式：定子(zi)塊固定在(zai)缸體上，而葉片(pian)和轉(zhuan)(zhuan)(zhuan)子(zi)連接(jie)在(zai)一起。根據進油方向，葉片(pian)將帶動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)(zhuan)子(zi)作往復擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)旋(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式又分單(dan)螺(luo)(luo)旋(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)和雙(shuang)螺(luo)(luo)旋(xuan)兩種(zhong)(zhong)，現在(zai)雙(shuang)螺(luo)(luo)旋(xuan)比較(jiao)常用，靠兩個螺(luo)(luo)旋(xuan)副降液壓缸內活塞的(de)直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)(zhuan)變(bian)為(wei)直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)與自(zi)轉(zhuan)(zhuan)(zhuan)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)復he運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，從而實現擺動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。
其(qi)次(ci)是裝(zhuang)配時有異物進入及(ji)(ji)密封材料(liao)質量不好。其(qi)后(hou)果則是動作(zuo)緩慢(man)、無力，嚴重(zhong)時還會造成活塞及(ji)(ji)缸(gang)筒的(de)損壞，出(chu)現(xian)“拉缸(gang)”現(xian)象。處理方法(fa)是調整速(su)度控制閥，對照安(an)裝(zhuang)說明應做必要的(de)操作(zuo)和改進。
(2)液(ye)壓(ya)回路(lu)泄漏(lou)。包括閥及液(ye)壓(ya)管路(lu)的泄漏(lou)。檢修(xiu)方法是通過操縱換向(xiang)閥檢查(cha)并消(xiao)除(chu)液(ye)壓(ya)連接管路(lu)的泄漏(lou)。
(3)液壓油經溢流閥旁通回油箱。
、液壓(ya)缸低速爬行的現象
液(ye)壓(ya)缸的活塞桿在油壓(ya)的作用(yong)下伸(shen)出(chu)(chu)或縮回時，經常(chang)出(chu)(chu)現(xian)(xian)速(su)(su)度不均勻現(xian)(xian)象，并(bing)有時伴有振(zhen)(zhen)(zhen)動(dong)(dong)和(he)異響，從而引起整個液(ye)壓(ya)系統的振(zhen)(zhen)(zhen)動(dong)(dong)，并(bing)帶動(dong)(dong)主機其它(ta)部件振(zhen)(zhen)(zhen)動(dong)(dong)，在主機調(diao)試過(guo)程中經常(chang)出(chu)(chu)現(xian)(xian)，有時速(su)(su)度快了(le)，這(zhe)種現(xian)(xian)象會減(jian)輕(qing)。除因液(ye)壓(ya)系統管路引起這(zhe)種現(xian)(xian)象以外，液(ye)壓(ya)缸自身產生的振(zhen)(zhen)(zhen)動(dong)(dong)也經常(chang)引發此類現(xian)(xian)象。
原因分析
液壓(ya)缸有桿腔和無桿腔存有氣(qi)體(ti)而產生(sheng)的低速(su)爬行，由于氣(qi)體(ti)混在(zai)(zai)液壓(ya)油(you)中，在(zai)(zai)壓(ya)力(li)的作用下，容器內(nei)體(ti)積變化，在(zai)(zai)高壓(ya)作用下甚至發生(sheng)氣(qi)體(ti)瞬間，從而引(yin)起液壓(ya)缸的速(su)度不穩定。
