粉體氣力輸送機的幾種形式

    氣(qi)力(li)(li)輸(shu)送(song)系(xi)(xi)統(tong)(tong)有幾種氣(qi)力(li)(li)輸(shu)送(song)形式，包括(kuo)正壓氣(qi)力(li)(li)輸(shu)送(song)系(xi)(xi)統(tong)(tong)、負壓氣(qi)力(li)(li)輸(shu)送(song)系(xi)(xi)統(tong)(tong)、混合系(xi)(xi)統(tong)(tong)和雙ji混合系(xi)(xi)統(tong)(tong)。下面簡單(dan)介紹一(yi)下這幾種氣(qi)力(li)(li)輸(shu)送(song)：

1、正壓氣力輸送系統

    正(zheng)(zheng)壓氣(qi)力輸送系統是(shi)行業中常用的，適用于(yu)文(wen)丘里式、螺桿(gan)泵、倉(cang)式泵等(deng)大多(duo)(duo)數給料機。在管(guan)道系統中安裝(zhuang)二通閥可(ke)實現多(duo)(duo)點卸料和加料。但(dan)多(duo)(duo)點供料喂料器過多(duo)(duo)，會造成大量(liang)漏風。特別是(shi)旋轉葉片(pian)送料器的泄(xie)漏量(liang)約占總(zong)供氣(qi)量(liang)的20%左右。目前(qian)，*內水(shui)泥廠輸送原料、煤(mei)粉、水(shui)泥等(deng)粉狀物(wu)料的氣(qi)力輸送系統基本采(cai)用正(zheng)(zheng)壓系統。

2、負壓氣力輸送(song)系統

    負壓(ya)氣(qi)(qi)力輸送系統(tong)適用于(yu)將物料(liao)(liao)(liao)從多個進料(liao)(liao)(liao)點(dian)輸送到一(yi)個卸料(liao)(liao)(liao)點(dian)。優(you)點(dian)是通過給料(liao)(liao)(liao)機(ji)(ji)的漏(lou)氣(qi)(qi)和(he)壓(ya)降都(dou)很(hen)小，因此旋片給料(liao)(liao)(liao)機(ji)(ji)可以令人滿意(yi)地使用。該系統(tong)在(zai)中*經常用于(yu)卸載(zai)小型散裝水泥(ni)駁船。

3、混合氣力輸送機系統

    混合(he)式氣力(li)輸送(song)系統(tong)(tong)(tong)結合(he)了正(zheng)壓(ya)和負壓(ya)系統(tong)(tong)(tong)的(de)優點。在該(gai)系統(tong)(tong)(tong)中，負壓(ya)部(bu)分將物料從多(duo)個(ge)進料倉吸走，而正(zheng)壓(ya)部(bu)分將物料送(song)入多(duo)個(ge)出料倉。空氣源(yuan)由(you)通風機或(huo)鼓風機提供。

4、兩級混合氣力輸送系統

    兩(liang)級混合氣(qi)(qi)力輸送(song)(song)系統(tong)(tong)比普通混合系統(tong)(tong)能更*地輸送(song)(song)物料(liao)。雖然(ran)普通攪拌系統(tong)(tong)非常適合許多車間的(de)短距離物料(liao)輸送(song)(song)，但由于(yu)系統(tong)(tong)壓力較(jiao)低，物料(liao)輸送(song)(song)量和(he)(he)輸送(song)(song)距離受到限(xian)制。兩(liang)級混合系統(tong)(tong)采用中間室將(jiang)負壓和(he)(he)正(zheng)壓系統(tong)(tong)分開(kai)，將(jiang)負壓和(he)(he)正(zheng)壓系統(tong)(tong)所需(xu)的(de)氣(qi)(qi)源分為兩(liang)個(ge)獨(du)立的(de)供氣(qi)(qi)裝(zhuang)置，以(yi)便zui*的(de)真空(kong)泵和(he)(he)空(kong)氣(qi)(qi)壓縮機(ji)可以(yi)分別選擇(ze)。
