擺動式液壓缸

擺動(dong)(dong)(dong)(dong)式(shi)(shi)液(ye)壓(ya)缸(gang)(gang)(gang)是輸(shu)出扭矩(ju)并(bing)實現往(wang)復(fu)運(yun)(yun)動(dong)(dong)(dong)(dong)的(de)執行元件，YHG1型(xing)冶(ye)金設(she)備(bei)標(biao)準(zhun)液(ye)壓(ya)缸(gang)(gang)(gang)廠商，有單(dan)葉(xie)片(pian)(pian)、雙(shuang)葉(xie)片(pian)(pian)、螺(luo)旋擺動(dong)(dong)(dong)(dong)等幾種形式(shi)(shi)。葉(xie)片(pian)(pian)式(shi)(shi)式(shi)(shi)：定(ding)子塊固定(ding)在缸(gang)(gang)(gang)體上，而(er)葉(xie)片(pian)(pian)和轉(zhuan)子連接在一(yi)起(qi)。根(gen)據進油方向，葉(xie)片(pian)(pian)將帶動(dong)(dong)(dong)(dong)轉(zhuan)子作(zuo)往(wang)復(fu)擺動(dong)(dong)(dong)(dong)。螺(luo)旋擺動(dong)(dong)(dong)(dong)式(shi)(shi)又(you)分單(dan)螺(luo)旋擺動(dong)(dong)(dong)(dong)和雙(shuang)螺(luo)旋兩(liang)種，液(ye)壓(ya)缸(gang)(gang)(gang)廠商，現在雙(shuang)螺(luo)旋比較常用(yong)，靠(kao)兩(liang)個螺(luo)旋副(fu)降液(ye)壓(ya)缸(gang)(gang)(gang)內活塞的(de)直線運(yun)(yun)動(dong)(dong)(dong)(dong)轉(zhuan)變為直線運(yun)(yun)動(dong)(dong)(dong)(dong)與自轉(zhuan)運(yun)(yun)動(dong)(dong)(dong)(dong)的(de)復(fu)he運(yun)(yun)動(dong)(dong)(dong)(dong)，從而(er)實現擺動(dong)(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)(dong)。

故障(zhang)診斷(威海力(li)建冶金(jin)液(ye)壓(ya)設備廠)

液(ye)壓(ya)(ya)缸(gang)是液(ye)壓(ya)(ya)系統中(zhong)將液(ye)壓(ya)(ya)能(neng)(neng)轉(zhuan)換為機(ji)(ji)械能(neng)(neng)的執行元件(jian)。其故(gu)障可基(ji)本歸納為液(ye)壓(ya)(ya)缸(gang)誤動(dong)作、無力推動(dong)負載以及(ji)活塞滑(hua)移或爬行等。由于液(ye)壓(ya)(ya)缸(gang)出(chu)現故(gu)障而導致設備停機(ji)(ji)的現象屢見不(bu)鮮，因此(ci)，應重視液(ye)壓(ya)(ya)缸(gang)的故(gu)障診斷與使用維護(hu)工作。

一、故障診斷及處理

1、誤動(dong)作或(huo)動(dong)作失靈

原因和處理方法有以下幾種(zhong)：

液壓缸的介紹

液(ye)(ye)壓(ya)(ya)(ya)缸(gang)(gang)(gang)是(shi)將(jiang)液(ye)(ye)壓(ya)(ya)(ya)能轉變為(wei)機械(xie)能的、做直線往復運(yun)動(dong)（或擺動(dong)運(yun)動(dong)）的液(ye)(ye)壓(ya)(ya)(ya)執(zhi)行元件。它結構簡單、工作可靠。用它來實現往復運(yun)動(dong)時，7-14MPa CJT拉桿式液(ye)(ye)壓(ya)(ya)(ya)缸(gang)(gang)(gang)廠商，可免去減速裝(zhuang)置，并(bing)且沒有傳(chuan)動(dong)間隙，運(yun)動(dong)平穩，因此在各種機械(xie)的液(ye)(ye)壓(ya)(ya)(ya)系統中得(de)到廣泛應用。液(ye)(ye)壓(ya)(ya)(ya)缸(gang)(gang)(gang)輸出力和活(huo)塞有效面積及其兩(liang)邊(bian)的壓(ya)(ya)(ya)差成正(zheng)比；液(ye)(ye)壓(ya)(ya)(ya)缸(gang)(gang)(gang)基(ji)本上(shang)由缸(gang)(gang)(gang)筒和缸(gang)(gang)(gang)蓋、活(huo)塞和活(huo)塞桿、密封裝(zhuang)置、緩(huan)沖(chong)裝(zhuang)置與排(pai)氣(qi)裝(zhuang)置組成。緩(huan)沖(chong)裝(zhuang)置與排(pai)氣(qi)裝(zhuang)置視具體應用場合而定，其他裝(zhuang)置則必不可少。
