HSG型(xing)工程用液(ye)壓(ya)缸

HSG型工程用(yong)液壓缸(gang)為雙作(zuo)用(yong)單活塞桿式液壓缸(gang)。具有安(an)裝連接方(fang)式多(duo)樣以及可帶緩沖裝置等特點。適用(yong)于工程機(ji)(ji)械(xie)、起重運輸(shu)機(ji)(ji)械(xie)、船舶機(ji)(ji)械(xie)、冶金礦山(shan)機(ji)(ji)械(xie)以及其它液壓系統。

DG型車輛用液壓缸(gang)

DG型(xing)車輛(liang)(liang)用液(ye)壓缸為雙作用單活(huo)塞桿式(shi)液(ye)壓缸，主要用于車輛(liang)(liang)、工程機械、起重機械、礦山機械、冶金機械及其(qi)它機械的液(ye)壓系統(tong)。

(1)閥芯卡住或(huo)(huo)(huo)閥孔(kong)(kong)堵塞。當流量閥或(huo)(huo)(huo)方向閥閥芯卡住或(huo)(huo)(huo)閥孔(kong)(kong)堵塞時(shi)，液(ye)壓(ya)缸易(yi)發生誤(wu)動作或(huo)(huo)(huo)動作失(shi)靈。此時(shi)應檢查(cha)油液(ye)的(de)污染情況；檢查(cha)臟物或(huo)(huo)(huo)膠質(zhi)沉淀物是否卡住閥芯或(huo)(huo)(huo)堵塞閥孔(kong)(kong)；檢查(cha)閥體的(de)磨損情況，清洗(xi)、更(geng)換(huan)系統過濾器，清洗(xi)油箱，更(geng)換(huan)液(ye)壓(ya)介質(zhi)。

(2)活塞桿與缸(gang)筒(tong)卡住或液壓(ya)缸(gang)堵(du)塞。此時(shi)無論如何操縱，液壓(ya)缸(gang)都不(bu)動作或動作甚微。這時(shi)應(ying)檢查活塞及(ji)活塞桿密封是(shi)否太緊(jin)，是(shi)否進入臟物(wu)及(ji)膠質沉淀物(wu)：活塞桿與缸(gang)筒(tong)的軸(zhou)心線是(shi)否對中，易(yi)損件和密封件是(shi)否失效，所帶負荷是(shi)否太大。

液壓缸(gang)結構基本上可以分為缸(gang)筒和缸(gang)蓋(gai)、活塞和活塞桿、密封(feng)裝置(zhi)、緩沖裝置(zhi)和排氣裝置(zhi)五個部分。今(jin)天威海力建小(xiao)編著(zhu)重(zhong)帶著(zhu)大家(jia)了解一(yi)下(xia)缸(gang)筒和缸(gang)蓋(gai)。

 缸筒和(he)缸蓋

一(yi)般來說，缸(gang)(gang)筒(tong)(tong)(tong)和(he)缸(gang)(gang)蓋的(de)結構形(xing)式(shi)(shi)(shi)和(he)其(qi)使(shi)用的(de)材(cai)料(liao)有關(guan)。工(gong)(gong)(gong)作壓力p＜10MPa時，使(shi)用鑄(zhu)鐵；p＜20MPa時，使(shi)用無縫鋼(gang)管(guan)；p＞20MPa時，使(shi)用鑄(zhu)鋼(gang)或鍛鋼(gang)。法蘭(lan)連(lian)(lian)(lian)接(jie)式(shi)(shi)(shi)，結構簡(jian)單(dan)，容(rong)(rong)易(yi)加(jia)工(gong)(gong)(gong)，也容(rong)(rong)易(yi)裝(zhuang)(zhuang)拆(chai)，但(dan)(dan)外(wai)形(xing)尺寸和(he)重量(liang)(liang)都(dou)較大，常用于鑄(zhu)鐵制的(de)缸(gang)(gang)筒(tong)(tong)(tong)上。半環(huan)連(lian)(lian)(lian)接(jie)式(shi)(shi)(shi)，它的(de)缸(gang)(gang)筒(tong)(tong)(tong)壁部因開了環(huan)形(xing)槽而(er)削弱(ruo)了強度，為此有時要(yao)(yao)加(jia)厚缸(gang)(gang)壁，它容(rong)(rong)易(yi)加(jia)工(gong)(gong)(gong)和(he)裝(zhuang)(zhuang)拆(chai)，重量(liang)(liang)較輕(qing)，常用于無縫鋼(gang)管(guan)或鍛鋼(gang)制的(de)缸(gang)(gang)筒(tong)(tong)(tong)上。螺(luo)紋(wen)連(lian)(lian)(lian)接(jie)式(shi)(shi)(shi)，它的(de)缸(gang)(gang)筒(tong)(tong)(tong)端部結構復雜，外(wai)徑加(jia)工(gong)(gong)(gong)時要(yao)(yao)求保證內外(wai)徑同心，裝(zhuang)(zhuang)拆(chai)要(yao)(yao)使(shi)用工(gong)(gong)(gong)具，它的(de)外(wai)形(xing)尺寸和(he)重量(liang)(liang)都(dou)較小，常用于無縫鋼(gang)管(guan)或鑄(zhu)鋼(gang)制的(de)缸(gang)(gang)筒(tong)(tong)(tong)上。拉(la)桿連(lian)(lian)(lian)接(jie)式(shi)(shi)(shi)，結構的(de)通用性(xing)大，容(rong)(rong)易(yi)加(jia)工(gong)(gong)(gong)和(he)裝(zhuang)(zhuang)拆(chai)，但(dan)(dan)外(wai)形(xing)尺寸較大，且較重。焊接(jie)連(lian)(lian)(lian)接(jie)式(shi)(shi)(shi)，結構簡(jian)單(dan)，尺寸小，但(dan)(dan)缸(gang)(gang)底處內徑不(bu)易(yi)加(jia)工(gong)(gong)(gong)，且可能引起變形(xing)。
