一、環鏈電動葫蘆怎么接線
1、需先安裝(zhuang)鏈盒。
2、連接電源線。
環鏈電動葫蘆的(de)(de)電(dian)(dian)(dian)機接線(xian)(xian)(xian)(xian)(xian)(xian)(xian)非(fei)常簡單,電(dian)(dian)(dian)機里(li)面只(zhi)有(you)(you)(you)一(yi)(yi)跟很粗(cu)的(de)(de)電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian),這一(yi)(yi)根電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)里(li)面有(you)(you)(you)4根細線(xian)(xian)(xian)(xian)(xian)(xian)(xian)擰在(zai)一(yi)(yi)起,3根是(shi)火線(xian)(xian)(xian)(xian)(xian)(xian)(xian)然后對應接在(zai)380v的(de)(de)電(dian)(dian)(dian)壓上就可以(yi)了(le),380V指的(de)(de)都(dou)是(shi)三(san)相交流電(dian)(dian)(dian)其中(zhong)有(you)(you)(you)三(san)根相線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(火線(xian)(xian)(xian)(xian)(xian)(xian)(xian)),一(yi)(yi)根零線(xian)(xian)(xian)(xian)(xian)(xian)(xian)。三(san)根火線(xian)(xian)(xian)(xian)(xian)(xian)(xian)之間(jian)的(de)(de)電(dian)(dian)(dian)壓是(shi)交流380V,三(san)根火線(xian)(xian)(xian)(xian)(xian)(xian)(xian)與零線(xian)(xian)(xian)(xian)(xian)(xian)(xian)之間(jian)的(de)(de)電(dian)(dian)(dian)壓是(shi)交流220V。連接電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)時(shi),必須提(ti)前切斷電(dian)(dian)(dian)源(yuan)。同時(shi)地(di)(di)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)應良好接地(di)(di),否則(ze)操作(zuo)者(zhe)觸摸葫蘆(lu)或鏈條的(de)(de)任(ren)何部(bu)位時(shi),都(dou)可能會感到有(you)(you)(you)電(dian)(dian)(dian)擊的(de)(de)感覺。
3、潤滑環鏈電動葫蘆的負載鏈
鏈(lian)條(tiao)的潤滑程度是影(ying)響負(fu)載鏈(lian)使(shi)用壽命的一個(ge)重要因素。及時有效地(di)潤滑負(fu)載鏈(lian),才(cai)能保證鏈(lian)條(tiao)的有效使(shi)用壽命。
4、檢查(cha)鏈(lian)條的(de)排列
對于(yu)多行鏈的環鏈電動葫蘆(lu),應確(que)保(bao)下鉤架不被翻(fan)轉。如果翻(fan)轉,將(jiang)其恢(hui)復(fu)至(zhi)正常狀態(tai),確(que)保(bao)鏈條(tiao)的焊(han)接口(kou)排列成行。切勿在鏈條(tiao)扭曲的葫蘆(lu)上懸掛負載。
5、檢查工(gong)作電壓
由于環鏈電(dian)動葫蘆出廠時,是(shi)按用戶指定的(de)電(dian)壓(ya)或較高的(de)電(dian)壓(ya)裝備的(de)(僅對雙(shuang)電(dian)壓(ya)而(er)言),如(ru)230/460V,需(xu)檢查(cha)接線(xian)并確認是(shi)否滿(man)足(zu)電(dian)源電(dian)壓(ya)的(de)要(yao)求(qiu)(qiu)。如(ru)果不符合,請參照說明書(shu)加以(yi)更(geng)正以(yi)滿(man)足(zu)必須的(de)工(gong)作電(dian)壓(ya)要(yao)求(qiu)(qiu)。
二、環鏈電動葫蘆安裝維護方法
1、新安(an)裝或經(jing)拆(chai)檢后安(an)裝的電動葫蘆,首先應進行空車試(shi)運(yun)轉(zhuan)數次。但在(zai)未安(an)裝完畢前(qian),切忌通電試(shi)轉(zhuan)。
2、電動(dong)環(huan)鏈葫蘆在正常(chang)使用前應進行(xing)以額定負(fu)荷(he)的125%,起升離地面約100毫米(mi),10分鐘(zhong)的靜(jing)負(fu)荷(he)試驗,并(bing)檢查(cha)是否正常(chang)。
3、動負(fu)荷試(shi)驗(yan)是以額定負(fu)荷重量,作反(fan)復升(sheng)降與左右移動試(shi)驗(yan),試(shi)驗(yan)后(hou)檢查其機(ji)械傳動部分(fen),電器部分(fen)和(he)連(lian)接部分(fen)是否(fou)正常可靠。
4、在使用中(zhong),絕對(dui)禁(jin)止在不允許的環(huan)境下(xia),及超過額(e)定(ding)負荷(he)和每小時(shi)額(e)定(ding)合(he)閘次數(120次)的情況下(xia)使用。
5、安(an)(an)裝(zhuang)調(diao)試和維(wei)護時(shi),必(bi)(bi)須(xu)嚴格檢(jian)查限位裝(zhuang)置(zhi)是否靈(ling)活可靠(kao),當吊(diao)鉤升至上極限位置(zhi)時(shi),吊(diao)鉤外(wai)殼到(dao)卷筒外(wai)殼之距離(li)必(bi)(bi)須(xu)大于(yu)50mm(10t,16t,20t必(bi)(bi)須(xu)大于(yu)120mm)。當吊(diao)鉤降至下(xia)極限位置(zhi)時(shi),應(ying)保證(zheng)卷筒上鋼絲繩安(an)(an)全圈(quan),有效(xiao)安(an)(an)全圈(quan)必(bi)(bi)須(xu)在2圈(quan)以(yi)上。
6、不允許同時按下兩個(ge)使電(dian)動環(huan)鏈葫蘆按相(xiang)反(fan)方向運動的手電(dian)門按鈕(niu)。
7、工(gong)作完畢(bi)后必須把電(dian)(dian)源的總閘拉(la)開,切斷電(dian)(dian)源。
8、電(dian)動(dong)環(huan)鏈葫(hu)蘆(lu)應(ying)由專人(ren)操(cao)縱,操(cao)縱者應(ying)充分掌握安全操(cao)作規程,嚴(yan)禁歪拉(la)斜(xie)吊。
9、在使(shi)用中必須由專門(men)人員(yuan)定(ding)期對電動環鏈葫(hu)蘆進行檢查,發現故(gu)障(zhang)及時采取措(cuo)施,并仔(zi)細(xi)加以記錄。
10、調整電動環鏈葫蘆制動下(xia)滑(hua)量(liang)時,應保證額(e)定載荷下(xia),制動下(xia)滑(hua)量(liang)S≤V/100(V為負載下(xia)一分鐘內穩定起升(sheng)的(de)距(ju)離)。
