擺動式液壓缸
擺(bai)動(dong)(dong)式(shi)液壓缸是輸(shu)出扭矩(ju)并(bing)實現往復(fu)運(yun)動(dong)(dong)的執(zhi)行元件，有(you)單葉片、雙(shuang)葉片、螺(luo)旋(xuan)(xuan)擺(bai)動(dong)(dong)等幾種形(xing)式(shi)。葉片式(shi)式(shi)：定子(zi)塊固(gu)定在缸體上，而葉片和轉(zhuan)子(zi)連接在一起。根據進油方向，葉片將帶動(dong)(dong)轉(zhuan)子(zi)作往復(fu)擺(bai)動(dong)(dong)。螺(luo)旋(xuan)(xuan)擺(bai)動(dong)(dong)式(shi)又分單螺(luo)旋(xuan)(xuan)擺(bai)動(dong)(dong)和雙(shuang)螺(luo)旋(xuan)(xuan)兩種，現在雙(shuang)螺(luo)旋(xuan)(xuan)比較(jiao)常用(yong)，靠兩個螺(luo)旋(xuan)(xuan)副降液壓缸內活塞的直(zhi)線運(yun)動(dong)(dong)轉(zhuan)變為直(zhi)線運(yun)動(dong)(dong)與自轉(zhuan)運(yun)動(dong)(dong)的復(fu)he運(yun)動(dong)(dong)，從而實現擺(bai)動(dong)(dong)運(yun)動(dong)(dong)。
其次是(shi)裝配時有異物進入及密封材料質量不好(hao)。其后果則是(shi)動(dong)作(zuo)緩慢、無力，嚴重時還會(hui)造成活(huo)塞及缸(gang)筒的損壞，出(chu)現“拉缸(gang)”現象。處理方法是(shi)調整速度控制閥，對照安(an)裝說明(ming)應做必要的操作(zuo)和改(gai)進。
(2)液(ye)壓回路(lu)泄(xie)(xie)漏。包括閥及(ji)液(ye)壓管(guan)(guan)路(lu)的(de)(de)泄(xie)(xie)漏。檢(jian)修方法是通過操縱(zong)換向閥檢(jian)查(cha)并消除(chu)液(ye)壓連接管(guan)(guan)路(lu)的(de)(de)泄(xie)(xie)漏。
(3)液(ye)壓(ya)油經溢流閥旁(pang)通(tong)回油箱。
液(ye)壓缸(gang)(gang)結構基本上可(ke)以分為缸(gang)(gang)筒和(he)(he)缸(gang)(gang)蓋、活塞和(he)(he)活塞桿、密(mi)封(feng)裝置、緩沖(chong)裝置和(he)(he)排(pai)氣裝置五個(ge)部(bu)分。今天威海力建(jian)小編(bian)著(zhu)重帶(dai)著(zhu)大家了解一(yi)下缸(gang)(gang)筒和(he)(he)缸(gang)(gang)蓋。
缸(gang)筒和缸(gang)蓋
一般來說，缸(gang)筒(tong)和(he)缸(gang)蓋的結構(gou)形(xing)(xing)(xing)式(shi)(shi)(shi)和(he)其使(shi)用(yong)(yong)(yong)的材料(liao)有(you)關。工(gong)作壓力p＜10MPa時，使(shi)用(yong)(yong)(yong)鑄鐵；p＜20MPa時，使(shi)用(yong)(yong)(yong)無(wu)(wu)縫鋼(gang)(gang)(gang)管；p＞20MPa時，使(shi)用(yong)(yong)(yong)鑄鋼(gang)(gang)(gang)或鍛鋼(gang)(gang)(gang)。法蘭(lan)連接式(shi)(shi)(shi)，結構(gou)簡單，容(rong)易加(jia)工(gong)，也容(rong)易裝拆(chai)，但(dan)外形(xing)(xing)(xing)尺(chi)寸(cun)和(he)重(zhong)量都(dou)較(jiao)大，常用(yong)(yong)(yong)于(yu)鑄鐵制的缸(gang)筒(tong)上(shang)。半環連接式(shi)(shi)(shi)，它(ta)的缸(gang)筒(tong)壁部因開(kai)了環形(xing)(xing)(xing)槽而削弱了強度，為此有(you)時要加(jia)厚缸(gang)壁，它(ta)容(rong)易加(jia)工(gong)和(he)裝拆(chai)，重(zhong)量較(jiao)輕(qing)，常用(yong)(yong)(yong)于(yu)無(wu)(wu)縫鋼(gang)(gang)(gang)管或鍛鋼(gang)(gang)(gang)制的缸(gang)筒(tong)上(shang)。螺紋(wen)連接式(shi)(shi)(shi)，它(ta)的缸(gang)筒(tong)端部結構(gou)復雜，外徑(jing)加(jia)工(gong)時要求保證內外徑(jing)同心，裝拆(chai)要使(shi)用(yong)(yong)(yong)工(gong)具，它(ta)的外形(xing)(xing)(xing)尺(chi)寸(cun)和(he)重(zhong)量都(dou)較(jiao)小(xiao)，常用(yong)(yong)(yong)于(yu)無(wu)(wu)縫鋼(gang)(gang)(gang)管或鑄鋼(gang)(gang)(gang)制的缸(gang)筒(tong)上(shang)。拉(la)桿連接式(shi)(shi)(shi)，結構(gou)的通(tong)用(yong)(yong)(yong)性大，容(rong)易加(jia)工(gong)和(he)裝拆(chai)，但(dan)外形(xing)(xing)(xing)尺(chi)寸(cun)較(jiao)大，且較(jiao)重(zhong)。焊(han)接連接式(shi)(shi)(shi)，結構(gou)簡單，尺(chi)寸(cun)小(xiao)，但(dan)缸(gang)底處內徑(jing)不(bu)易加(jia)工(gong)，且可能(neng)引起變形(xing)(xing)(xing)。
