擺動式液壓缸
擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)液壓缸是(shi)輸出扭(niu)矩并(bing)實現(xian)往(wang)復運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)執行(xing)元件(jian)，有(you)單(dan)葉(xie)片(pian)、雙(shuang)葉(xie)片(pian)、螺(luo)旋(xuan)(xuan)(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)等幾種形式(shi)。葉(xie)片(pian)式(shi)式(shi)：定(ding)(ding)子(zi)塊固(gu)定(ding)(ding)在(zai)缸體上(shang)，而(er)(er)葉(xie)片(pian)和轉(zhuan)(zhuan)子(zi)連接在(zai)一起。根據進油(you)方向，葉(xie)片(pian)將帶(dai)動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子(zi)作往(wang)復擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)(xuan)(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)又分單(dan)螺(luo)旋(xuan)(xuan)(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)和雙(shuang)螺(luo)旋(xuan)(xuan)(xuan)兩種，現(xian)在(zai)雙(shuang)螺(luo)旋(xuan)(xuan)(xuan)比較常(chang)用，靠兩個螺(luo)旋(xuan)(xuan)(xuan)副降(jiang)液壓缸內活塞的(de)直(zhi)線(xian)(xian)運動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變為(wei)直(zhi)線(xian)(xian)運動(dong)(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)復he運動(dong)(dong)(dong)(dong)(dong)(dong)，從而(er)(er)實現(xian)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)(dong)(dong)。
若溢(yi)流閥(fa)(fa)(fa)進(jin)入(ru)臟物卡住閥(fa)(fa)(fa)芯，使溢(yi)流閥(fa)(fa)(fa)常(chang)開(kai)，液(ye)壓(ya)(ya)(ya)油會經溢(yi)流閥(fa)(fa)(fa)旁通(tong)直(zhi)接流回(hui)油箱，導(dao)致液(ye)壓(ya)(ya)(ya)缸(gang)沒油進(jin)入(ru)。若負載過大(da)，溢(yi)流閥(fa)(fa)(fa)的(de)調節(jie)壓(ya)(ya)(ya)力雖已達到(dao)極大(da)額定值，但液(ye)壓(ya)(ya)(ya)缸(gang)仍(reng)得(de)不(bu)(bu)到(dao)連續動作所需的(de)推力而(er)不(bu)(bu)動作。若調節(jie)壓(ya)(ya)(ya)力較(jiao)低，則因壓(ya)(ya)(ya)力不(bu)(bu)足達不(bu)(bu)到(dao)仍(reng)載所需的(de)椎力，表現為推力不(bu)(bu)夠(gou)。此時應檢查并(bing)調整(zheng)溢(yi)流閥(fa)(fa)(fa)。(威(wei)海(hai)力建冶(ye)金液(ye)壓(ya)(ya)(ya)設備廠(chang))
①缸體組件
缸(gang)體組(zu)件由液壓(ya)缸(gang)缸(gang)筒(tong)與端蓋組(zu)成(cheng),缸(gang)筒(tong)與端蓋有多種聯接形式.
②活塞組件
活(huo)塞組件由活(huo)塞與活(huo)塞桿構成,活(huo)塞和活(huo)塞桿除常用的螺紋(wen)(wen)聯(lian)接(jie)外,也(ye)可采用'非螺紋(wen)(wen)式'聯(lian)接(jie). ③密封裝置
在活(huo)塞和(he)活(huo)塞桿的(de)(de)(de)運動(dong)部(bu)分,端蓋和(he)缸筒間的(de)(de)(de)靜(jing)止部(bu)分等處都需要設置可(ke)靠的(de)(de)(de)密(mi)封(feng).密(mi)封(feng)是提高系統性能與效率的(de)(de)(de)有效措(cuo)施.
④緩沖裝置
大(da)型,高速(su)及(ji)精(jing)度的液壓缸應(ying)設(she)有緩沖裝(zhuang)置,常見的液壓缸緩沖裝(zhuang)置有環狀間隙式(shi),節流口可(ke)調式(shi)和節流口可(ke)變(bian)式(shi)等幾(ji)種.
⑤排氣裝置
液(ye)壓(ya)(ya)缸(gang)(gang)中(zhong)存在(zai)空氣(qi)將使其運(yun)動不平穩,當壓(ya)(ya)力(li)增大時會產生(sheng)絕熱壓(ya)(ya)縮而造成(cheng)局部高溫,因此應(ying)在(zai)液(ye)壓(ya)(ya)缸(gang)(gang)的高部位上(shang)設(she)置(zhi)排氣(qi)裝置(zhi).
排氣裝置通常有珠形(xing)閥式排氣閥和錐(zhui)形(xing)閥式排氣閥兩種形(xing)式.
