起重機制動器如何選購

　　起重機制動器如何(he)選(xuan)購

　　我們考慮(lv)到起(qi)重機制(zhi)(zhi)動(dong)器(qi)(qi)的使用場所，如(ru)制(zhi)(zhi)動(dong)器(qi)(qi)安裝有足夠的空間，可選(xuan)用塊(kuai)式、帶式制(zhi)(zhi)動(dong)器(qi)(qi)或(huo)臂(bei)式盤形制(zhi)(zhi)動(dong)器(qi)(qi)，空間受(shou)***時，可選(xuan)用內蹄(ti)式或(huo)鉗(qian)形起(qi)重機制(zhi)(zhi)動(dong)器(qi)(qi)。

　　起重機制動器的類(lei)型的選擇，主(zhu)要根據主(zhu)機(ji)或機(ji)構(gou)(gou)的產品標(biao)準(zhun)要求和實(shi)際需要，確定制動(dong)器(qi)(qi)的類(lei)型。如(ru)標(biao)準(zhun)規定：起升機(ji)構(gou)(gou)、變(bian)幅機(ji)構(gou)(gou)必須設置(zhi)常閉式(shi)制動(dong)器(qi)(qi)，行走或回(hui)轉機(ji)構(gou)(gou)可選用常閉式(shi)制動(dong)器(qi)(qi)。

　　考慮到配套主機(ji)的使(shi)用環(huan)(huan)境，起重機(ji)制(zhi)動(dong)器(qi)對滲漏油有嚴格要求(qiu)的場(chang)合應(ying)選(xuan)(xuan)用電(dian)(dian)磁或氣(qi)動(dong)制(zhi)動(dong)器(qi)，對環(huan)(huan)境溫度較高的冶金場(chang)所可選(xuan)(xuan)用絕緣等(deng)級較高的電(dian)(dian)力液壓(ya)制(zhi)動(dong)器(qi)或冶金型電(dian)(dian)磁制(zhi)動(dong)器(qi)。在環(huan)(huan)境溫度較低或較高，且露(lu)天場(chang)所選(xuan)(xuan)用電(dian)(dian)力液壓(ya)制(zhi)動(dong)器(qi)時(shi)，應(ying)注意更換相(xiang)應(ying)牌號的液壓(ya)油。

　　在含鐵屑、粉塵嚴(yan)重(zhong)的(de)(de)(de)(de)環境(jing)中(zhong)，應避免(mian)使(shi)用電磁鐵制動(dong)(dong)(dong)器(qi)，防止粉塵進入電磁鐵間隙影響(xiang)電磁鐵的(de)(de)(de)(de)吸合。對于(yu)(yu)特(te)殊(shu)或重(zhong)要的(de)(de)(de)(de)場合，應根據(ju)需要增(zeng)(zeng)設制動(dong)(dong)(dong)器(qi)的(de)(de)(de)(de)附加(jia)(jia)功能。起重(zhong)機制動(dong)(dong)(dong)器(qi)在溫度(du)較(jiao)低的(de)(de)(de)(de)環境(jing)中(zhong)，可使(shi)用電力(li)液壓推動(dong)(dong)(dong)器(qi)的(de)(de)(de)(de)加(jia)(jia)熱(re)器(qi)。對于(yu)(yu)啟動(dong)(dong)(dong)與制動(dong)(dong)(dong)過(guo)程轉換(huan)有嚴(yan)格要求時，加(jia)(jia)裝(zhuang)行程開(kai)(kai)關以了(le)解(jie)制動(dong)(dong)(dong)器(qi)的(de)(de)(de)(de)開(kai)(kai)閉狀態。對于(yu)(yu)維護、調(diao)整較(jiao)難實施的(de)(de)(de)(de)環境(jing)，可加(jia)(jia)裝(zhuang)制動(dong)(dong)(dong)間隙均等裝(zhuang)置和摩擦片磨損(sun)自動(dong)(dong)(dong)補償裝(zhuang)置。增(zeng)(zeng)設手動(dong)(dong)(dong)松閘裝(zhuang)置可在特(te)殊(shu)情況(kuang)下人工打開(kai)(kai)制動(dong)(dong)(dong)器(qi)。
