粉體氣力輸送機是(shi)利用(yong)(yong)空氣的(de)(de)能量來(lai)進(jin)行粉(fen)粒狀散裝物料連(lian)續輸(shu)(shu)(shu)送的(de)(de)輸(shu)(shu)(shu)運技術(shu)。氣力(li)(li)輸(shu)(shu)(shu)送的(de)(de)研究(jiu)涉及多(duo)個學科(ke)分支，對工業生產具有重要的(de)(de)現實(shi)意義。由(you)于(yu)氣力(li)(li)輸(shu)(shu)(shu)送為氣固(gu)(gu)兩相流(liu)，內部流(liu)型(xing)復雜，氣力(li)(li)輸(shu)(shu)(shu)送中氣固(gu)(gu)的(de)(de)比例是(shi)多(duo)少(shao)?主要看(kan)選(xuan)用(yong)(yong)的(de)(de)是(shi)哪種輸(shu)(shu)(shu)送形式(shi)？

       氣力輸送機從輸(shu)送(song)(song)形(xing)式上簡單來說(shuo)分為(wei)(wei)正(zheng)壓氣(qi)力輸(shu)送(song)(song)和負(fu)壓氣(qi)力輸(shu)送(song)(song)，負(fu)壓氣(qi)力輸(shu)送(song)(song)采用(yong)(yong)的(de)動力源泉有離(li)心風(feng)機料(liao)(liao)氣(qi)比較低，一般(ban)為(wei)(wei)0.5-3左右。而(er)正(zheng)壓氣(qi)力輸(shu)送(song)(song)采用(yong)(yong)的(de)是旋渦風(feng)機、羅茨風(feng)機、水環(huan)真空(kong)泵(beng)之類要高些(xie)大(da)概在3-10左右。如果用(yong)(yong)壓縮空(kong)氣(qi)即倉泵(beng)來輸(shu)送(song)(song)的(de)話料(liao)(liao)氣(qi)比就高些(xie)，一般(ban)為(wei)(wei)20-50左右，總而(er)言之，正(zheng)壓的(de)料(liao)(liao)氣(qi)比相對負(fu)壓的(de)料(liao)(liao)氣(qi)比要高些(xie)。
