擺動式液壓缸
擺動(dong)(dong)式(shi)液壓(ya)缸是輸出扭(niu)矩并實(shi)現往復(fu)運(yun)(yun)動(dong)(dong)的(de)執行元件，有單(dan)葉片(pian)、雙葉片(pian)、螺(luo)(luo)旋(xuan)(xuan)擺動(dong)(dong)等幾種(zhong)形式(shi)。葉片(pian)式(shi)式(shi)：定(ding)子塊(kuai)固定(ding)在缸體上，而葉片(pian)和轉(zhuan)(zhuan)子連接在一(yi)起。根據進油方向，葉片(pian)將(jiang)帶(dai)動(dong)(dong)轉(zhuan)(zhuan)子作往復(fu)擺動(dong)(dong)。螺(luo)(luo)旋(xuan)(xuan)擺動(dong)(dong)式(shi)又分單(dan)螺(luo)(luo)旋(xuan)(xuan)擺動(dong)(dong)和雙螺(luo)(luo)旋(xuan)(xuan)兩種(zhong)，現在雙螺(luo)(luo)旋(xuan)(xuan)比較(jiao)常(chang)用，靠兩個螺(luo)(luo)旋(xuan)(xuan)副(fu)降液壓(ya)缸內(nei)活(huo)塞的(de)直(zhi)(zhi)線(xian)運(yun)(yun)動(dong)(dong)轉(zhuan)(zhuan)變為直(zhi)(zhi)線(xian)運(yun)(yun)動(dong)(dong)與自轉(zhuan)(zhuan)運(yun)(yun)動(dong)(dong)的(de)復(fu)he運(yun)(yun)動(dong)(dong)，從而實(shi)現擺動(dong)(dong)運(yun)(yun)動(dong)(dong)。
其次(ci)是(shi)裝配時(shi)有(you)異物進(jin)入(ru)及(ji)密封材(cai)料質量不好。其后果則是(shi)動(dong)作(zuo)緩慢(man)、無力，嚴重時(shi)還(huan)會造(zao)成活塞及(ji)缸筒的損壞，出現(xian)“拉缸”現(xian)象。處理方法是(shi)調整速度(du)控(kong)制閥，對照安裝說明應做(zuo)必(bi)要(yao)的操作(zuo)和(he)改進(jin)。
(2)液壓回路泄漏。包括閥及(ji)液壓管路的泄漏。檢修方法是(shi)通過操縱換向閥檢查(cha)并消(xiao)除液壓連接(jie)管路的泄漏。
(3)液壓油經(jing)溢流閥旁通回油箱。
液(ye)壓缸(gang)(gang)結構基本上可以分為缸(gang)(gang)筒和缸(gang)(gang)蓋、活塞和活塞桿、密封裝置、緩沖裝置和排氣裝置五個部分。今天威(wei)海力建小編著(zhu)(zhu)重(zhong)帶著(zhu)(zhu)大家了解一下(xia)缸(gang)(gang)筒和缸(gang)(gang)蓋。
缸筒(tong)和缸蓋
一(yi)般(ban)來說，缸(gang)(gang)(gang)筒(tong)和(he)缸(gang)(gang)(gang)蓋(gai)的(de)(de)(de)結構(gou)(gou)形式(shi)和(he)其使用(yong)的(de)(de)(de)材(cai)料有關。工(gong)(gong)(gong)作壓力p＜10MPa時，使用(yong)鑄(zhu)鐵；p＜20MPa時，使用(yong)無(wu)(wu)縫鋼管；p＞20MPa時，使用(yong)鑄(zhu)鋼或鍛鋼。法蘭連(lian)接(jie)式(shi)，結構(gou)(gou)簡單(dan)(dan)，容(rong)易加工(gong)(gong)(gong)，也容(rong)易裝拆，但外(wai)(wai)形尺(chi)寸和(he)重量都較(jiao)(jiao)(jiao)大(da)，常(chang)用(yong)于鑄(zhu)鐵制的(de)(de)(de)缸(gang)(gang)(gang)筒(tong)上(shang)。半環連(lian)接(jie)式(shi)，它的(de)(de)(de)缸(gang)(gang)(gang)筒(tong)壁部因開了環形槽而削弱了強度，為此有時要(yao)(yao)(yao)加厚(hou)缸(gang)(gang)(gang)壁，它容(rong)易加工(gong)(gong)(gong)和(he)裝拆，重量較(jiao)(jiao)(jiao)輕，常(chang)用(yong)于無(wu)(wu)縫鋼管或鍛鋼制的(de)(de)(de)缸(gang)(gang)(gang)筒(tong)上(shang)。螺紋(wen)連(lian)接(jie)式(shi)，它的(de)(de)(de)缸(gang)(gang)(gang)筒(tong)端部結構(gou)(gou)復雜，外(wai)(wai)徑(jing)加工(gong)(gong)(gong)時要(yao)(yao)(yao)求保證(zheng)內外(wai)(wai)徑(jing)同心，裝拆要(yao)(yao)(yao)使用(yong)工(gong)(gong)(gong)具(ju)，它的(de)(de)(de)外(wai)(wai)形尺(chi)寸和(he)重量都較(jiao)(jiao)(jiao)小(xiao)，常(chang)用(yong)于無(wu)(wu)縫鋼管或鑄(zhu)鋼制的(de)(de)(de)缸(gang)(gang)(gang)筒(tong)上(shang)。拉桿連(lian)接(jie)式(shi)，結構(gou)(gou)的(de)(de)(de)通用(yong)性大(da)，容(rong)易加工(gong)(gong)(gong)和(he)裝拆，但外(wai)(wai)形尺(chi)寸較(jiao)(jiao)(jiao)大(da)，且較(jiao)(jiao)(jiao)重。焊接(jie)連(lian)接(jie)式(shi)，結構(gou)(gou)簡單(dan)(dan)，尺(chi)寸小(xiao)，但缸(gang)(gang)(gang)底(di)處內徑(jing)不易加工(gong)(gong)(gong)，且可能引起變形。
