众所周知，失重式喂料(liao)(liao)系统，是一种散状(zhuang)物料(liao)(liao)的(de)输(shu)送(song)设(she)备。失重式喂料(liao)(liao)机(ji)一方(fang)面能够(gou)输(shu)送(song)颗粒大小在(zai)(zai)5mm以(yi)下的(de)细小物料(liao)(liao)，另一方(fang)面，此设(she)备还能输(shu)送(song)边长(zhang)1m以(yi)上(shang)的(de)大块(kuai)物料(liao)(liao)。它具有连续(xu)均匀输(shu)送(song)、可调节(jie)性(xing)以(yi)及适应(ying)性(xing)强(qiang)等(deng)优点，因此，在(zai)(zai)建材、冶金(jin)、电力、煤炭、化工(gong)铸造(zao)等(deng)行(xing)业的(de)物料(liao)(liao)的(de)处理生产线上(shang)得到(dao)广泛应(ying)用，在(zai)(zai)水泥行(xing)业中，用于(yu)大块(kuai)状(zhuang)石灰石或石膏从矿(kuang)仓底(di)部到(dao)破碎(sui)机(ji)的(de)输(shu)送(song)，起到(dao)连续(xu)均匀喂料(liao)(liao)作(zuo)用，可以(yi)大大提高工(gong)作(zuo)效率。

对于失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)不(bu)(bu)能(neng)(neng)重(zhong)(zhong)(zhong)(zhong)载(zai)(zai)启动(dong)问题，目前采取解决(jue)的(de)办法(fa)包括三条，di一，减(jian)小(xiao)矿(kuang)石对失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)的(de)冲(chong)击，传统做法(fa)是根据各单(dan)位具体(ti)情况，通过(guo)(guo)试验(yan)减(jian)小(xiao)料仓(cang)后(hou)壁的(de)倾(qing)角，但这种做法(fa)会使物料下(xia)滑不(bu)(bu)畅(chang)，对生(sheng)产产生(sheng)不(bu)(bu)利影响，这样(yang)为了一方面不(bu)(bu)影响生(sheng)产，另一方面又能(neng)(neng)解决(jue)冲(chong)击问题，可以(yi)对入(ru)料仓(cang)的(de)矿(kuang)石进行粒度限制，如(ru)必须小(xiao)于800毫米，对失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)后(hou)部(bu)(bu)的(de)厚度也要有一定要求，如(ru)必须在1米以(yi)上;第(di)二，还(hai)可以(yi)通过(guo)(guo)增强(qiang)失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)的(de)抗冲(chong)击能(neng)(neng)力(li)，这可以(yi)通过(guo)(guo)加(jia)强(qiang)失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)后(hou)部(bu)(bu)的(de)支撑横梁、增强(qiang)失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)后(hou)部(bu)(bu)滑轨的(de)抗冲(chong)击能(neng)(neng)力(li);第(di)三，还(hai)可以(yi)通过(guo)(guo)校核失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)主(zhu)电(dian)(dian)机(ji)(ji)(ji)(ji)的(de)启动(dong)能(neng)(neng)力(li)加(jia)以(yi)改善，通过(guo)(guo)一般的(de)受力(li)分析之后(hou)，结(jie)果表明，失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)不(bu)(bu)能(neng)(neng)重(zhong)(zhong)(zhong)(zhong)载(zai)(zai)启动(dong)的(de)原(yuan)因主(zhu)要是由于失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)主(zhu)电(dian)(dian)机(ji)(ji)(ji)(ji)的(de)启动(dong)转(zhuan)矩与(yu)负载(zai)(zai)转(zhuan)矩不(bu)(bu)匹配。因此对失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)主(zhu)电(dian)(dian)机(ji)(ji)(ji)(ji)进行了更换，可以(yi)选用既经济又能(neng)(neng)满足(zu)重(zhong)(zhong)(zhong)(zhong)载(zai)(zai)启动(dong)要求的(de)失(shi)重(zhong)(zhong)(zhong)(zhong)式(shi)(shi)喂(wei)(wei)料机(ji)(ji)(ji)(ji)主(zhu)电(dian)(dian)机(ji)(ji)(ji)(ji)。
