旋回式破碎機堵料跳(tiao)停(ting)的主要原因是破碎(sui)機下腔體中(zhong)積料太(tai)多排不出,頂住動錐,造成電念頭過載跳(tiao)停(ting)。通過多年經驗總結出以下兩種跳(tiao)停(ting)的原因及其(qi)解決(jue)辦法(fa)。
1、 破碎(sui)機產(chan)量高,板式(shi)輸送(song)機來不及拉走(zou);
2、 下(xia)游(you)設(she)備(bei)跳停,破(po)碎機繼承破(po)碎。這種情況一(yi)量發生,要(yao)將破(po)碎腔內的物料全部理出來才(cai)能繼承開機,費(fei)時(shi)費(fei)力,一(yi)般起碼都(dou)要(yao)3~4小(xiao)時(shi)才(cai)能完成。
該(gai)方法簡樸(pu)、可靠、本(ben)錢(qian)低.同(tong)時也(ye)減輕了工人的(de)勞動負擔,進步了破(po)碎(sui)機的(de)出產(chan)效率。
設(she)定(ding)的板(ban)式(shi)(shi)輸送(song)(song)(song)機(ji)(ji)報警電(dian)流值(zhi)要適當(dang),不(bu)能太低(di),也不(bu)能太高(gao)。太低(di)破(po)(po)碎(sui)(sui)(sui)(sui)機(ji)(ji)會常常斷料(liao)(liao)(liao),石頭會砸(za)板(ban)式(shi)(shi)輸送(song)(song)(song)機(ji)(ji),設(she)定(ding)太高(gao),下腔體(ti)(ti)積(ji)料(liao)(liao)(liao)多,緩(huan)沖空間不(bu)夠(gou),假如下游(you)設(she)備故(gu)障也輕易(yi)導致破(po)(po)碎(sui)(sui)(sui)(sui)機(ji)(ji)堵料(liao)(liao)(liao)。實踐證實33A設(she)定(ding)值(zhi)即保(bao)證破(po)(po)碎(sui)(sui)(sui)(sui)機(ji)(ji)出料(liao)(liao)(liao)連續不(bu)亂,也給破(po)(po)碎(sui)(sui)(sui)(sui)機(ji)(ji)下腔體(ti)(ti)留有(you)足(zu)夠(gou)的緩(huan)沖空間,能有(you)效防止堵料(liao)(liao)(liao)。因(yin)為破(po)(po)碎(sui)(sui)(sui)(sui)機(ji)(ji)下重型式(shi)(shi)輸送(song)(song)(song)機(ji)(ji)的運(yun)行(xing)電(dian)流與下腔體(ti)(ti)內(nei)的物(wu)料(liao)(liao)(liao)多少有(you)很好的相關性,而且每(mei)次下腔體(ti)(ti)內(nei)多引(yin)起(qi)破(po)(po)碎(sui)(sui)(sui)(sui)機(ji)(ji)跳停時,板(ban)式(shi)(shi)輸送(song)(song)(song)機(ji)(ji)的電(dian)流都超過了一(yi)個固定(ding)的峰值(zhi)(38A),空載電(dian)流也是(shi)一(yi)個固定(ding)值(zhi)(18A)。
在破碎機倒(dao)(dao)(dao)料(liao)(liao)口安裝一個電(dian)(dian)鈴及報(bao)(bao)警閃爍(shuo)燈(deng),與電(dian)(dian)氣(qi)柜內繼電(dian)(dian)器(qi)直接相連,當板(ban)式(shi)輸送(song)機達到一個設(she)定的電(dian)(dian)流(liu)(liu)值(33A)時(shi),繼電(dian)(dian)器(qi)吸(xi)合,報(bao)(bao)警燈(deng)開始閃爍(shuo),電(dian)(dian)鈴也響起來。假如下(xia)游設(she)備(bei)跳停,板(ban)式(shi)輸送(song)機電(dian)(dian)流(liu)(liu)為零時(shi),聲(sheng)光(guang)報(bao)(bao)警也會有提(ti)示(shi)(shi)。礦車司機接到報(bao)(bao)警提(ti)示(shi)(shi)后會休止(zhi)(zhi)倒(dao)(dao)(dao)料(liao)(liao),從而(er)防止(zhi)(zhi)堵料(liao)(liao)。為了防止(zhi)(zhi)堵料(liao)(liao),采用(yong)通過聲(sheng)光(guang)指(zhi)示(shi)(shi)器(qi)方(fang)式(shi)直接指(zhi)示(shi)(shi)倒(dao)(dao)(dao)料(liao)(liao),效果很(hen)好(hao)。
