擺動式液壓缸
擺動(dong)(dong)(dong)(dong)式液壓缸(gang)是輸出扭矩并實現往復(fu)運動(dong)(dong)(dong)(dong)的(de)執(zhi)行元(yuan)件(jian)，有單(dan)葉(xie)(xie)片、雙葉(xie)(xie)片、螺(luo)(luo)旋(xuan)擺動(dong)(dong)(dong)(dong)等幾種形式。葉(xie)(xie)片式式：定子塊固定在(zai)缸(gang)體上，而(er)葉(xie)(xie)片和轉(zhuan)(zhuan)子連接(jie)在(zai)一起。根據進油方向，葉(xie)(xie)片將帶動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子作往復(fu)擺動(dong)(dong)(dong)(dong)。螺(luo)(luo)旋(xuan)擺動(dong)(dong)(dong)(dong)式又(you)分單(dan)螺(luo)(luo)旋(xuan)擺動(dong)(dong)(dong)(dong)和雙螺(luo)(luo)旋(xuan)兩(liang)(liang)種，現在(zai)雙螺(luo)(luo)旋(xuan)比較常用(yong)，靠兩(liang)(liang)個螺(luo)(luo)旋(xuan)副降液壓缸(gang)內活塞(sai)的(de)直線運動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變為(wei)直線運動(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)運動(dong)(dong)(dong)(dong)的(de)復(fu)he運動(dong)(dong)(dong)(dong)，從(cong)而(er)實現擺動(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)。
其次是裝配(pei)時有異(yi)物進入及(ji)密封(feng)材(cai)料質(zhi)量不好。其后果(guo)則(ze)是動作(zuo)緩慢、無(wu)力，嚴重(zhong)時還會造成(cheng)活(huo)塞及(ji)缸筒的(de)損壞(huai)，出現“拉缸”現象。處理方(fang)法是調整速度(du)控(kong)制閥，對照安裝說明應做(zuo)必要的(de)操作(zuo)和改(gai)進。
(2)液壓回路泄漏(lou)。包括(kuo)閥及液壓管路的泄漏(lou)。檢修方(fang)法是通過(guo)操縱換向閥檢查并消除液壓連接管路的泄漏(lou)。
(3)液壓油經溢(yi)流閥(fa)旁通(tong)回油箱。
液壓缸(gang)(gang)結構(gou)基本上(shang)可(ke)以分為缸(gang)(gang)筒(tong)和缸(gang)(gang)蓋(gai)、活塞(sai)和活塞(sai)桿、密封裝(zhuang)置、緩沖裝(zhuang)置和排氣裝(zhuang)置五個部(bu)分。今天威海力建(jian)小編著(zhu)重帶(dai)著(zhu)大家(jia)了解一下缸(gang)(gang)筒(tong)和缸(gang)(gang)蓋(gai)。
缸筒和缸蓋
一(yi)般來說，缸(gang)(gang)(gang)筒和(he)(he)缸(gang)(gang)(gang)蓋的結(jie)構(gou)(gou)形式和(he)(he)其使(shi)(shi)(shi)用(yong)(yong)的材料(liao)有關。工(gong)(gong)(gong)作壓(ya)力p＜10MPa時(shi)(shi)，使(shi)(shi)(shi)用(yong)(yong)鑄(zhu)鐵；p＜20MPa時(shi)(shi)，使(shi)(shi)(shi)用(yong)(yong)無縫鋼管(guan)；p＞20MPa時(shi)(shi)，使(shi)(shi)(shi)用(yong)(yong)鑄(zhu)鋼或鍛鋼。法(fa)蘭(lan)連接(jie)式，結(jie)構(gou)(gou)簡單(dan)(dan)，容(rong)易(yi)(yi)(yi)加(jia)(jia)工(gong)(gong)(gong)，也(ye)容(rong)易(yi)(yi)(yi)裝拆(chai)(chai)，但外形尺寸和(he)(he)重(zhong)(zhong)(zhong)量都(dou)較大(da)(da)，常(chang)用(yong)(yong)于鑄(zhu)鐵制的缸(gang)(gang)(gang)筒上(shang)。半環(huan)連接(jie)式，它的缸(gang)(gang)(gang)筒壁(bi)(bi)部因開了環(huan)形槽而削弱(ruo)了強度，為此有時(shi)(shi)要加(jia)(jia)厚缸(gang)(gang)(gang)壁(bi)(bi)，它容(rong)易(yi)(yi)(yi)加(jia)(jia)工(gong)(gong)(gong)和(he)(he)裝拆(chai)(chai)，重(zhong)(zhong)(zhong)量較輕，常(chang)用(yong)(yong)于無縫鋼管(guan)或鍛鋼制的缸(gang)(gang)(gang)筒上(shang)。螺紋(wen)連接(jie)式，它的缸(gang)(gang)(gang)筒端部結(jie)構(gou)(gou)復雜，外徑(jing)加(jia)(jia)工(gong)(gong)(gong)時(shi)(shi)要求保證內外徑(jing)同心，裝拆(chai)(chai)要使(shi)(shi)(shi)用(yong)(yong)工(gong)(gong)(gong)具，它的外形尺寸和(he)(he)重(zhong)(zhong)(zhong)量都(dou)較小，常(chang)用(yong)(yong)于無縫鋼管(guan)或鑄(zhu)鋼制的缸(gang)(gang)(gang)筒上(shang)。拉桿連接(jie)式，結(jie)構(gou)(gou)的通(tong)用(yong)(yong)性大(da)(da)，容(rong)易(yi)(yi)(yi)加(jia)(jia)工(gong)(gong)(gong)和(he)(he)裝拆(chai)(chai)，但外形尺寸較大(da)(da)，且較重(zhong)(zhong)(zhong)。焊接(jie)連接(jie)式，結(jie)構(gou)(gou)簡單(dan)(dan)，尺寸小，但缸(gang)(gang)(gang)底(di)處內徑(jing)不易(yi)(yi)(yi)加(jia)(jia)工(gong)(gong)(gong)，且可能引起(qi)變形。
