擺動式液壓缸
擺(bai)(bai)動(dong)(dong)(dong)(dong)式液壓缸是輸出(chu)扭矩并實現(xian)(xian)往復運(yun)(yun)動(dong)(dong)(dong)(dong)的執行元件，有單(dan)葉片(pian)、雙葉片(pian)、螺(luo)(luo)(luo)(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)等幾種(zhong)形式。葉片(pian)式式：定子(zi)塊固定在(zai)(zai)缸體上，而葉片(pian)和轉(zhuan)子(zi)連接在(zai)(zai)一(yi)起。根據(ju)進油(you)方(fang)向，葉片(pian)將(jiang)帶動(dong)(dong)(dong)(dong)轉(zhuan)子(zi)作往復擺(bai)(bai)動(dong)(dong)(dong)(dong)。螺(luo)(luo)(luo)(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)式又分單(dan)螺(luo)(luo)(luo)(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)和雙螺(luo)(luo)(luo)(luo)旋(xuan)兩(liang)種(zhong)，現(xian)(xian)在(zai)(zai)雙螺(luo)(luo)(luo)(luo)旋(xuan)比較常(chang)用，靠兩(liang)個(ge)螺(luo)(luo)(luo)(luo)旋(xuan)副降液壓缸內活塞的直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)轉(zhuan)變為直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)與自(zi)轉(zhuan)運(yun)(yun)動(dong)(dong)(dong)(dong)的復he運(yun)(yun)動(dong)(dong)(dong)(dong)，從而實現(xian)(xian)擺(bai)(bai)動(dong)(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)(dong)。
緩沖裝置
在液(ye)壓系(xi)統中使(shi)用液(ye)壓缸(gang)(gang)驅動(dong)(dong)具有(you)一(yi)定質(zhi)量的機構，當液(ye)壓缸(gang)(gang)運動(dong)(dong)至行(xing)程(cheng)終點時(shi)具有(you)較大動(dong)(dong)能，如(ru)未作減(jian)速處理(li)，液(ye)壓缸(gang)(gang)活塞與缸(gang)(gang)蓋將發生(sheng)機械碰撞，產生(sheng)沖(chong)(chong)擊、噪聲，有(you)破(po)壞性。為緩和及防(fang)止(zhi)這種危害發生(sheng)，因(yin)此可在液(ye)壓回(hui)路中設置減(jian)速裝(zhuang)置或在缸(gang)(gang)體(ti)內設緩沖(chong)(chong)裝(zhuang)置。
加工
缸(gang)筒作(zuo)為(wei)液(ye)壓(ya)缸(gang)、礦用單體(ti)支(zhi)柱、液(ye)壓(ya)支(zhi)架、炮管(guan)等產品(pin)的主(zhu)要部件，其(qi)加(jia)工(gong)質(zhi)量的好壞直(zhi)接(jie)影響整個產品(pin)的壽(shou)命(ming)和可靠性(xing)。缸(gang)筒加(jia)工(gong)要求高，其(qi)內表面粗糙度(du)要求為(wei)Ra0.4～0.8&um，對同(tong)軸度(du)、耐磨性(xing)要求嚴格。缸(gang)筒的基本(ben)特征是深孔加(jia)工(gong)，其(qi)加(jia)工(gong)一(yi)直(zhi)困擾加(jia)工(gong)人員。
若(ruo)溢(yi)流閥進入臟物卡住閥芯，使(shi)溢(yi)流閥常(chang)開，液(ye)壓(ya)(ya)(ya)油會經溢(yi)流閥旁通(tong)直接流回(hui)油箱，導致(zhi)液(ye)壓(ya)(ya)(ya)缸沒油進入。若(ruo)負(fu)載過大，溢(yi)流閥的調(diao)節壓(ya)(ya)(ya)力(li)(li)(li)(li)雖已達(da)到極大額定值，但液(ye)壓(ya)(ya)(ya)缸仍(reng)得不(bu)到連續動(dong)作所需的推力(li)(li)(li)(li)而不(bu)動(dong)作。若(ruo)調(diao)節壓(ya)(ya)(ya)力(li)(li)(li)(li)較低，則因(yin)壓(ya)(ya)(ya)力(li)(li)(li)(li)不(bu)足(zu)達(da)不(bu)到仍(reng)載所需的椎(zhui)力(li)(li)(li)(li)，表現為推力(li)(li)(li)(li)不(bu)夠。此時應檢查并調(diao)整溢(yi)流閥。(威海力(li)(li)(li)(li)建冶(ye)金(jin)液(ye)壓(ya)(ya)(ya)設(she)備廠)
