(1)閥芯卡住或(huo)(huo)閥孔堵(du)(du)塞。當流(liu)量閥或(huo)(huo)方向(xiang)閥閥芯卡住或(huo)(huo)閥孔堵(du)(du)塞時，液壓缸易發生誤動作或(huo)(huo)動作失靈(ling)。此時應檢查(cha)油(you)液的(de)(de)污染情況；檢查(cha)臟(zang)物或(huo)(huo)膠(jiao)質沉淀(dian)物是(shi)否卡住閥芯或(huo)(huo)堵(du)(du)塞閥孔；檢查(cha)閥體的(de)(de)磨損情況，清洗、更換(huan)系統(tong)過濾器，清洗油(you)箱，更換(huan)液壓介質。

(2)活塞(sai)桿與缸(gang)(gang)筒卡(ka)住或(huo)液壓缸(gang)(gang)堵塞(sai)。此時無論如何操縱(zong)，重載液壓缸(gang)(gang)價格，液壓缸(gang)(gang)都不動(dong)(dong)作(zuo)或(huo)動(dong)(dong)作(zuo)甚微。這時應(ying)檢查活塞(sai)及活塞(sai)桿密(mi)(mi)封是否(fou)太緊，是否(fou)進(jin)入臟物及膠(jiao)質(zhi)沉淀(dian)物：活塞(sai)桿與缸(gang)(gang)筒的(de)軸心線(xian)是否(fou)對(dui)中(zhong)，易損件和(he)密(mi)(mi)封件是否(fou)失效，所(suo)帶(dai)負荷是否(fou)太大(da)。

YHG1型(xing)冶金(jin)設備標準液壓缸

Y-HG1型冶(ye)金設備(bei)標準液壓(ya)缸，為(wei)雙作(zuo)用單活(huo)塞桿(gan)液壓(ya)缸，缸徑從(cong)40~320mm共有17種規(gui)格(ge)，CDCG350系列(lie)重載液壓(ya)缸價格(ge)，額定(ding)(ding)壓(ya)力為(wei)16MPa，可以帶緩(huan)沖裝(zhuang)(zhuang)(zhuang)置。該(gai)系列(lie)液壓(ya)缸有13種安裝(zhuang)(zhuang)(zhuang)連接型式，除軸向腳架式外，安裝(zhuang)(zhuang)(zhuang)連裝(zhuang)(zhuang)(zhuang)尺寸均符(fu)合ISO6021/1-1981的規(gui)定(ding)(ding)。活(huo)塞桿(gan)端螺紋亦(yi)符(fu)合GB2350-80的規(gui)定(ding)(ding)。適用于工(gong)作(zuo)溫度為(wei)-30C~+80C，工(gong)作(zuo)介質為(wei)液壓(ya)油，乳化液的冶(ye)金設備(bei)（不適用于磷酸(suan)脂）。

擺動式液壓缸

擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)液壓缸是輸出扭矩并實(shi)現(xian)往(wang)復(fu)運(yun)(yun)動(dong)(dong)(dong)(dong)的執(zhi)行元件(jian)，DG型車輛用(yong)液壓缸價(jia)格(ge)，有單(dan)葉(xie)片(pian)、雙葉(xie)片(pian)、螺(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)等幾種形式(shi)。葉(xie)片(pian)式(shi)式(shi)：定(ding)(ding)子塊(kuai)固定(ding)(ding)在(zai)缸體上，而葉(xie)片(pian)和轉子連接(jie)在(zai)一起(qi)。根據(ju)進油方向，葉(xie)片(pian)將(jiang)帶(dai)動(dong)(dong)(dong)(dong)轉子作往(wang)復(fu)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)。螺(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)又(you)分單(dan)螺(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)和雙螺(luo)旋兩(liang)種，液壓缸價(jia)格(ge)，現(xian)在(zai)雙螺(luo)旋比較常用(yong)，靠兩(liang)個螺(luo)旋副降液壓缸內活(huo)塞的直線運(yun)(yun)動(dong)(dong)(dong)(dong)轉變為直線運(yun)(yun)動(dong)(dong)(dong)(dong)與自轉運(yun)(yun)動(dong)(dong)(dong)(dong)的復(fu)he運(yun)(yun)動(dong)(dong)(dong)(dong)，從而實(shi)現(xian)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)(dong)。
