活塞式(shi)液壓缸的工作原理

活塞式(shi)(shi)液(ye)(ye)壓(ya)(ya)缸(gang)(gang)可分(fen)為(wei)單桿式(shi)(shi)和雙桿式(shi)(shi)兩(liang)種結構，其固(gu)定方式(shi)(shi)由缸(gang)(gang)體固(gu)定和活塞桿固(gu)定兩(liang)種，液(ye)(ye)壓(ya)(ya)缸(gang)(gang)價格，按液(ye)(ye)壓(ya)(ya)力(li)的(de)作用(yong)情況(kuang)有單作用(yong)式(shi)(shi)和雙作用(yong)式(shi)(shi)。在單作用(yong)式(shi)(shi)液(ye)(ye)壓(ya)(ya)缸(gang)(gang)中，HSG型工(gong)程用(yong)液(ye)(ye)壓(ya)(ya)缸(gang)(gang)價格，壓(ya)(ya)力(li)油只供液(ye)(ye)壓(ya)(ya)缸(gang)(gang)的(de)一腔(qiang)，靠(kao)液(ye)(ye)壓(ya)(ya)力(li)使缸(gang)(gang)實現(xian)單方向(xiang)運(yun)動，反方向(xiang)運(yun)動則靠(kao)外(wai)力(li)（如彈(dan)簧力(li)、自(zi)重或(huo)外(wai)部載荷等）來實現(xian)；（威海力(li)建(jian)冶金液(ye)(ye)壓(ya)(ya)設備廠(chang)提供）

擺動式液壓缸

擺(bai)動(dong)(dong)(dong)(dong)(dong)式液(ye)壓(ya)缸(gang)是輸出扭矩并(bing)實現往復(fu)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的執(zhi)行元件，拉桿式液(ye)壓(ya)缸(gang)價格，有單(dan)葉(xie)片(pian)、雙(shuang)(shuang)葉(xie)片(pian)、螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)等幾種形(xing)式。葉(xie)片(pian)式式：定子塊(kuai)固定在缸(gang)體上，而葉(xie)片(pian)和轉(zhuan)子連接在一起。根據(ju)進油方向，葉(xie)片(pian)將帶動(dong)(dong)(dong)(dong)(dong)轉(zhuan)子作(zuo)往復(fu)擺(bai)動(dong)(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)式又(you)分單(dan)螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)和雙(shuang)(shuang)螺(luo)旋(xuan)兩(liang)(liang)種，現在雙(shuang)(shuang)螺(luo)旋(xuan)比較(jiao)常用，靠兩(liang)(liang)個螺(luo)旋(xuan)副降液(ye)壓(ya)缸(gang)內活塞(sai)的直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)變為直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的復(fu)he運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，從(cong)而實現擺(bai)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)。

活塞(sai)式液(ye)壓缸的工作原(yuan)理

它只在活(huo)塞(sai)的(de)一側設有活(huo)塞(sai)桿，因而兩腔(qiang)的(de)有效作(zuo)用面積不(bu)(bu)同(tong)(tong)。在供油(you)量相同(tong)(tong)時(shi)，不(bu)(bu)同(tong)(tong)腔(qiang)進油(you)，活(huo)塞(sai)的(de)運(yun)(yun)動速度不(bu)(bu)同(tong)(tong)；在需克服的(de)負(fu)載力(li)相同(tong)(tong)時(shi)，不(bu)(bu)同(tong)(tong)腔(qiang)進油(you)，所需要(yao)的(de)供油(you)壓(ya)力(li)不(bu)(bu)同(tong)(tong)，或者說在系統壓(ya)力(li)調定后，環衛(wei)垃(la)圾車液壓(ya)缸兩個(ge)方(fang)向運(yun)(yun)動所能克服的(de)負(fu)載力(li)不(bu)(bu)同(tong)(tong)。
