干灰氣力輸送設備-75t鍋爐粉煤灰氣力輸送系統
噴射輸送泵和粉體氣力輸送機料封泵(beng)(beng)都是基于射(she)流泵(beng)(beng)原理工作的(de)，核心部件是一(yi)(yi)個噴嘴和一(yi)(yi)個文丘利管構成的(de)射(she)流泵(beng)(beng)。
噴射輸(shu)(shu)送泵(beng)在氣(qi)、汽(qi)、液、粉 物料的輸(shu)(shu)送上(shang)都(dou)有應用(yong)，氣(qi)力輸(shu)(shu)送泵(beng)基本(ben)上(shang)都(dou)用(yong)于粉料輸(shu)(shu)送。
噴射輸送(song)泵的噴嘴是連續工作（噴射）的，在輸送(song)粉(fen)(fen)料時需要(yao)另行將粉(fen)(fen)料流化后進入射流泵部分。
氣力輸送機料(liao)封泵的(de)噴嘴是工作在脈(mo)沖狀態下(xia)的(de)，這種(zhong)狀態在輸送粉料(liao)時有利于物(wu)料(liao)直(zhi)接流化進入(ru)射流泵部分。
低(di)壓(ya)氣(qi)力輸送泵是(shi)利用氣(qi)流(liu)射流(liu)作(zuo)用，使空(kong)氣(qi)帶(dai)動灰(hui)粒把灰(hui)送到灰(hui)庫(ku)，低(di)壓(ya)氣(qi)力輸送泵主要有四部(bu)(bu)分(fen)(fen)組成分(fen)(fen)別為(wei)噴嘴(zui)、圓柱形泵體、噴嘴(zui)調(diao)節裝(zhuang)(zhuang)置、底部(bu)(bu)汽化(hua)裝(zhuang)(zhuang)置，低(di)壓(ya)氣(qi)力輸送泵工作(zuo)時(shi)的能量來自二部(bu)(bu)分(fen)(fen)：一(yi)部(bu)(bu)分(fen)(fen)是(shi)風機的動能，另一(yi)部(bu)(bu)分(fen)(fen)是(shi)料柱的勢(shi)能。料柱高、勢(shi)能大、壓(ya)力大、輸送量相(xiang)應就大，反之(zhi)則小。
低(di)壓(ya)氣(qi)(qi)力(li)(li)(li)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)泵的(de)特點：結構(gou)簡單，操(cao)作簡單，操(cao)作量少，能(neng)連續不斷(duan)送(song)(song)(song)(song)(song)灰，它(ta)能(neng)夠(gou)自(zi)動調整料封泵出(chu)力(li)(li)(li)，能(neng)夠(gou)很*的(de)達到送(song)(song)(song)(song)(song)灰的(de)效(xiao)果，送(song)(song)(song)(song)(song)灰媒介壓(ya)力(li)(li)(li)低(di)，設備管道閥門不宜磨損。低(di)壓(ya)氣(qi)(qi)力(li)(li)(li)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)泵是一種新型的(de)粉體氣(qi)(qi)力(li)(li)(li)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)設備，在當量距離450m，高度40m范(fan)圍內使用(yong)效(xiao)果zui*。相較于傳統的(de)粉體輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)設備（倉(cang)泵、負壓(ya)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)）投資小(xiao)、無故障、維護費用(yong)低(di)。低(di)壓(ya)氣(qi)(qi)力(li)(li)(li)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)系統現(xian)在已(yi)廣泛(fan)應用(yong)于水泥廠(chang)成品(pin)水泥輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)及火電廠(chang)粉煤灰輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)系統。
