推動器推動器

更換連接制動(dong)器的元(yuan)件(jian)。檢查卡鉗和制動(dong)輪缸(gang)是否泄漏。如確實(shi)有泄漏，必要(yao)時(shi)更換這些(xie)部件(jian)。n制(zhi)動(dong)器(qi)(qi)的(de)(de)類型(xing)較多，首先介紹其主要的(de)(de)分(fen)(fen)類方(fang)法(fa)。按構造特征的(de)(de)不(bu)同(tong)，它(ta)可以分(fen)(fen)為：塊(kuai)式制(zhi)動(dong)器(qi)(qi)，盤式制(zhi)動(dong)器(qi)(qi)，帶式制(zhi)動(dong)器(qi)(qi)。按工作狀態的(de)(de)不(bu)同(tong)，它(ta)可以分(fen)(fen)為：常閉式制(zhi)動(dong)器(qi)(qi)：當(dang)起重機不(bu)工作時(shi)，制(zhi)動(dong)器(qi)(qi)處(chu)于閉合狀態，當(dang)起重機工作時(shi)，制(zhi)動(dong)器(qi)(qi)才松開(kai)。

常(chang)開式(shi)(shi)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)器(qi)：制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)器(qi)經常(chang)處于松開狀態，只有在需(xu)要制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)時才閉合。為(wei)了(le)保證安全(quan)，對于起(qi)升(sheng)機構(gou)(gou)(gou)、變幅(fu)機構(gou)(gou)(gou)，采用(yong)常(chang)閉式(shi)(shi)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)器(qi)。常(chang)開式(shi)(shi)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)器(qi)具(ju)(ju)(ju)有制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)力的(de)大(da)小(xiao)可以調節、制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)平穩等(deng)優點，它(ta)適用(yong)于輪式(shi)(shi)車輛的(de)運行(xing)機構(gou)(gou)(gou)和具(ju)(ju)(ju)有大(da)幅(fu)度的(de)旋轉(zhuan)機構(gou)(gou)(gou)。按驅動(dong)(dong)方(fang)式(shi)(shi)的(de)不同，它(ta)可以分為(wei)：自(zi)動(dong)(dong)作用(yong)式(shi)(shi)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)器(qi)，操縱式(shi)(shi)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)器(qi)。要求各種制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)器(qi)具(ju)(ju)(ju)備下列性(xing)能(neng)：制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)時具(ju)(ju)(ju)有足夠(gou)的(de)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)力矩。

易損零件要(yao)有較高(gao)的(de)(de)(de)耐(nai)磨(mo)性和耐(nai)熱性。在設(she)計或選擇制(zhi)(zhi)動器(qi)時，制(zhi)(zhi)動器(qi)的(de)(de)(de)制(zhi)(zhi)動力矩必(bi)須具有足夠的(de)(de)(de)儲(chu)備，即根據(ju)起重機使用情況(kuang)保證一定的(de)(de)(de)安(an)全系數(shu)，對于安(an)全性有高(gao)度要(yao)求的(de)(de)(de)機構(gou)，需要(yao)裝(zhuang)設(she)兩個(ge)支持制(zhi)(zhi)動器(qi)。n液壓制(zhi)(zhi)(zhi)動(dong)(dong)器(qi)的(de)工作情(qing)況是，踏下制(zhi)(zhi)(zhi)動(dong)(dong)踏板，活(huo)塞推(tui)桿推(tui)動(dong)(dong)活(huo)塞壓縮總泵(beng)(beng)內的(de)制(zhi)(zhi)(zhi)動(dong)(dong)液，使(shi)制(zhi)(zhi)(zhi)動(dong)(dong)液產(chan)生壓力經油管進入制(zhi)(zhi)(zhi)動(dong)(dong)分(fen)(fen)泵(beng)(beng)，分(fen)(fen)泵(beng)(beng)活(huo)塞將制(zhi)(zhi)(zhi)動(dong)(dong)蹄推(tui)靠到制(zhi)(zhi)(zhi)動(dong)(dong)鼓上。

產生秘動(dong)(dong)作用。那么今天就給大(da)家講解一下其制(zhi)(zhi)動(dong)(dong)不靈的原因(yin)是什么。液壓(ya)制(zhi)(zhi)動(dong)(dong)器制(zhi)(zhi)動(dong)(dong)不靈的主要原因(yin)是什么：制(zhi)(zhi)動(dong)(dong)系統中有(you)空氣(qi)；總泵補償孔或(huo)加油(you)(you)口蓋(gai)的通氣(qi)孔堵塞；總泵與分(fen)(fen)泵活(huo)塞磨損過(guo)甚而漏油(you)(you)；總泵、分(fen)(fen)泵皮碗(wan)損壞變形；油(you)(you)管有(you)裂縫或(huo)接頭松動(dong)(dong)而漏油(you)(you)；制(zhi)(zhi)動(dong)(dong)鼓(gu)失(shi)圓，磨出(chu)溝槽或(huo)鼓(gu)壁過(guo)薄；制(zhi)(zhi)動(dong)(dong)摩擦片接觸不良(liang)、硬化，鉚(liu)釘(ding)露出(chu)或(huo)有(you)油(you)(you)污。
