太原料封泵的發展與*內外粉體氣力輸送機設備進行對比分析
料封泵的發展與*內外粉體氣力輸送機設備進行對比分析。
大宇機械對(dui)*內外(wai)料(liao)封泵(beng)(beng)(beng)氣(qi)力(li)輸(shu)送(song)裝(zhuang)置進行了(le)合理的(de)(de)分(fen)析比較(jiao)，并對(dui)料(liao)封泵(beng)(beng)(beng)進行了(le)合理的(de)(de)改造。目前，粉體輸(shu)送(song)設(she)備中使用的(de)(de)氣(qi)力(li)輸(shu)送(song)裝(zhuang)置主要有兩(liang)種(zhong)類型。一(yi)般(ban)的(de)(de)輸(shu)送(song)方(fang)(fang)式(shi)是通過負壓氣(qi)力(li)輸(shu)送(song)粉狀、顆粒狀物料(liao)，*內外(wai)大多(duo)采用正(zheng)壓輸(shu)送(song)方(fang)(fang)式(shi)。輸(shu)送(song)機結構(gou)主要分(fen)為兩(liang)類，由于這(zhe)種(zhong)輸(shu)送(song)方(fang)(fang)式(shi)輸(shu)送(song)距離(li)較(jiao)長，因此對(dui)料(liao)封泵(beng)(beng)(beng)的(de)(de)施工有良*的(de)(de)效果。
在老式的粉體氣力輸送機設備(bei)中(zhong)，當(dang)時(shi)粉(fen)體(ti)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)廣泛采用螺桿泵(beng)(beng)(beng)和(he)皮(pi)帶(dai)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)。由(you)(you)于(yu)(yu)(yu)工(gong)(gong)業環保的(de)(de)(de)(de)要(yao)(yao)求(qiu)(qiu)，皮(pi)帶(dai)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)粉(fen)料(liao)(liao)(liao)(liao)已被淘汰(tai)。20世紀80年代引進*際**的(de)(de)(de)(de)美(mei)*粉(fen)體(ti)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)設備(bei)。;螺桿泵(beng)(beng)(beng)為懸浮式稀相輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)機，輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)風速較高。結構簡(jian)單，幾乎沒有(you)運動部件(jian)，因(yin)此故障少，幾乎無(wu)噪音；由(you)(you)于(yu)(yu)(yu)高壓懸浮倉(cang)式氣力輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)泵(beng)(beng)(beng)的(de)(de)(de)(de)風速較高，脈沖螺栓流氣力輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)泵(beng)(beng)(beng)；它是(shi)料(liao)(liao)(liao)(liao)封(feng)(feng)泵(beng)(beng)(beng)發(fa)展的(de)(de)(de)(de)前身。其(qi)工(gong)(gong)作(zuo)原理是(shi)：將物(wu)料(liao)(liao)(liao)(liao)裝入推流泵(beng)(beng)(beng)中(zhong)，并在(zai)(zai)壓縮空(kong)氣的(de)(de)(de)(de)作(zuo)用下(xia)；常見的(de)(de)(de)(de)氣力輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)是(shi)依靠被輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)氣體(ti)的(de)(de)(de)(de)動壓力進行承載和(he)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)。20世紀80年代，由(you)(you)合肥院主辦，引進了*際**的(de)(de)(de)(de)美(mei)*FULLER公司M型(xing)F-K螺桿泵(beng)(beng)(beng)的(de)(de)(de)(de)設計(ji)和(he)制造(zao)技術。該(gai)設備(bei)再次在(zai)(zai)料(liao)(liao)(liao)(liao)封(feng)(feng)泵(beng)(beng)(beng)的(de)(de)(de)(de)研發(fa)中(zhong)發(fa)揮了至關(guan)重(zhong)要(yao)(yao)的(de)(de)(de)(de)作(zuo)用。其(qi)主要(yao)(yao)優點是(shi)：螺旋軸采用雙支撐，出(chu)料(liao)(liao)(liao)(liao)口可根據工(gong)(gong)藝要(yao)(yao)求(qiu)(qiu)直接或左右兩側出(chu)料(liao)(liao)(liao)(liao)，密(mi)(mi)封(feng)(feng)采用油封(feng)(feng)。且氣密(mi)(mi)封(feng)(feng)，工(gong)(gong)作(zuo)更可靠。該(gai)泵(beng)(beng)(beng)用于(yu)(yu)(yu)連續(xu)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)物(wu)料(liao)(liao)(liao)(liao)，并能(neng)以額定(ding)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)量(liang)的(de)(de)(de)(de)0～100%的(de)(de)(de)(de)可變速率輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)物(wu)料(liao)(liao)(liao)(liao)。輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)過程無(wu)脈沖，輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)量(liang)可達數百噸(dun)。在(zai)(zai)同等運輸(shu)(shu)(shu)(shu)體(ti)積的(de)(de)(de)(de)前提下(xia)，具有(you)Z小的(de)(de)(de)(de)體(ti)積。因(yin)此特(te)別適用于(yu)(yu)(yu)干法(fa)水泥(ni)生產線煅燒過程中(zhong)煤粉(fen)的(de)(de)(de)(de)運輸(shu)(shu)(shu)(shu)，也(ye)適用于(yu)(yu)(yu)大型(xing)散(san)裝水泥(ni)船(chuan)的(de)(de)(de)(de)運輸(shu)(shu)(shu)(shu)和(he)散(san)裝水泥(ni)船(chuan)的(de)(de)(de)(de)改造(zao)。因(yin)此，料(liao)(liao)(liao)(liao)封(feng)(feng)泵(beng)(beng)(beng)的(de)(de)(de)(de)發(fa)展離不開老式料(liao)(liao)(liao)(liao)倉(cang)泵(beng)(beng)(beng)的(de)(de)(de)(de)使用。
