擺動式液壓缸
擺(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)液(ye)壓缸是輸出扭矩(ju)并實現(xian)(xian)往復運(yun)動(dong)(dong)(dong)(dong)的執行元件，有單(dan)葉(xie)片(pian)(pian)、雙葉(xie)片(pian)(pian)、螺(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)等幾種形式(shi)。葉(xie)片(pian)(pian)式(shi)式(shi)：定子塊固定在(zai)缸體上(shang)，而(er)葉(xie)片(pian)(pian)和轉子連接在(zai)一起(qi)。根(gen)據(ju)進油方(fang)向，葉(xie)片(pian)(pian)將(jiang)帶動(dong)(dong)(dong)(dong)轉子作(zuo)往復擺(bai)(bai)動(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)又分單(dan)螺(luo)旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)和雙螺(luo)旋(xuan)兩(liang)種，現(xian)(xian)在(zai)雙螺(luo)旋(xuan)比(bi)較常用，靠(kao)兩(liang)個螺(luo)旋(xuan)副降液(ye)壓缸內活塞(sai)的直線運(yun)動(dong)(dong)(dong)(dong)轉變為(wei)直線運(yun)動(dong)(dong)(dong)(dong)與自轉運(yun)動(dong)(dong)(dong)(dong)的復he運(yun)動(dong)(dong)(dong)(dong)，從而(er)實現(xian)(xian)擺(bai)(bai)動(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)。
其次是裝(zhuang)配時有異物進入及密封材料質量(liang)不(bu)好。其后果(guo)則是動作緩慢、無力，嚴重時還會造(zao)成活塞及缸(gang)(gang)筒的損(sun)壞，出現(xian)(xian)“拉缸(gang)(gang)”現(xian)(xian)象。處理方法是調整速度控制閥(fa)，對照安裝(zhuang)說(shuo)明(ming)應做必要的操作和改進。
(2)液壓(ya)回路泄漏(lou)。包括閥(fa)及液壓(ya)管(guan)路的泄漏(lou)。檢修(xiu)方法是通過操縱(zong)換向閥(fa)檢查并消除液壓(ya)連接管(guan)路的泄漏(lou)。
(3)液壓油經溢流閥(fa)旁通回油箱(xiang)。
液壓缸結構基本上可以分(fen)(fen)為(wei)缸筒和缸蓋、活塞和活塞桿、密封裝置(zhi)、緩沖裝置(zhi)和排(pai)氣裝置(zhi)五(wu)個(ge)部分(fen)(fen)。今天威海力(li)建(jian)小編著(zhu)重(zhong)帶著(zhu)大家了解一(yi)下(xia)缸筒和缸蓋。
缸筒和缸蓋
一般來(lai)說，缸(gang)筒(tong)(tong)和(he)(he)缸(gang)蓋(gai)的(de)結構(gou)形(xing)(xing)(xing)(xing)式(shi)(shi)和(he)(he)其(qi)使(shi)(shi)(shi)用(yong)(yong)(yong)的(de)材料有關(guan)。工(gong)作(zuo)壓力p＜10MPa時(shi)(shi)，使(shi)(shi)(shi)用(yong)(yong)(yong)鑄鐵；p＜20MPa時(shi)(shi)，使(shi)(shi)(shi)用(yong)(yong)(yong)無縫鋼(gang)管；p＞20MPa時(shi)(shi)，使(shi)(shi)(shi)用(yong)(yong)(yong)鑄鋼(gang)或(huo)鍛鋼(gang)。法蘭連接(jie)式(shi)(shi)，結構(gou)簡(jian)單，容(rong)(rong)(rong)易(yi)(yi)加工(gong)，也容(rong)(rong)(rong)易(yi)(yi)裝(zhuang)(zhuang)拆，但外(wai)形(xing)(xing)(xing)(xing)尺寸和(he)(he)重(zhong)(zhong)量都較(jiao)大(da)(da)，常用(yong)(yong)(yong)于(yu)鑄鐵制(zhi)的(de)缸(gang)筒(tong)(tong)上(shang)。半環連接(jie)式(shi)(shi)，它的(de)缸(gang)筒(tong)(tong)壁(bi)部(bu)因開了(le)環形(xing)(xing)(xing)(xing)槽而削(xue)弱了(le)強度，為此有時(shi)(shi)要(yao)加厚缸(gang)壁(bi)，它容(rong)(rong)(rong)易(yi)(yi)加工(gong)和(he)(he)裝(zhuang)(zhuang)拆，重(zhong)(zhong)量較(jiao)輕，常用(yong)(yong)(yong)于(yu)無縫鋼(gang)管或(huo)鍛鋼(gang)制(zhi)的(de)缸(gang)筒(tong)(tong)上(shang)。螺紋連接(jie)式(shi)(shi)，它的(de)缸(gang)筒(tong)(tong)端(duan)部(bu)結構(gou)復雜(za)，外(wai)徑(jing)加工(gong)時(shi)(shi)要(yao)求保證內(nei)外(wai)徑(jing)同心(xin)，裝(zhuang)(zhuang)拆要(yao)使(shi)(shi)(shi)用(yong)(yong)(yong)工(gong)具，它的(de)外(wai)形(xing)(xing)(xing)(xing)尺寸和(he)(he)重(zhong)(zhong)量都較(jiao)小(xiao)(xiao)，常用(yong)(yong)(yong)于(yu)無縫鋼(gang)管或(huo)鑄鋼(gang)制(zhi)的(de)缸(gang)筒(tong)(tong)上(shang)。拉桿連接(jie)式(shi)(shi)，結構(gou)的(de)通(tong)用(yong)(yong)(yong)性大(da)(da)，容(rong)(rong)(rong)易(yi)(yi)加工(gong)和(he)(he)裝(zhuang)(zhuang)拆，但外(wai)形(xing)(xing)(xing)(xing)尺寸較(jiao)大(da)(da)，且較(jiao)重(zhong)(zhong)。焊接(jie)連接(jie)式(shi)(shi)，結構(gou)簡(jian)單，尺寸小(xiao)(xiao)，但缸(gang)底處內(nei)徑(jing)不(bu)易(yi)(yi)加工(gong)，且可能引起變形(xing)(xing)(xing)(xing)。
