粉體氣力輸送機是一(yi)種常用(yong)(yong)的粉狀物(wu)(wu)料輸(shu)(shu)送(song)(song)方式，適用(yong)(yong)于(yu)輸(shu)(shu)送(song)(song)各(ge)種粉狀、顆粒狀和纖維狀物(wu)(wu)料。負壓(ya)氣力輸(shu)(shu)送(song)(song)的工作原理(li)是利用(yong)(yong)氣流將物(wu)(wu)料從一(yi)個輸(shu)(shu)送(song)(song)點(dian)輸(shu)(shu)送(song)(song)到另(ling)一(yi)個輸(shu)(shu)送(song)(song)點(dian)，通過控制(zhi)氣流來控制(zhi)物(wu)(wu)料的輸(shu)(shu)送(song)(song)量(liang)和輸(shu)(shu)送(song)(song)速度(du)。

       在(zai)實際應用中，負壓(ya)氣(qi)力輸(shu)送(song)(song)的輸(shu)送(song)(song)高(gao)度(du)取(qu)決于(yu)(yu)很(hen)多因素，如(ru)物(wu)料(liao)的性質、輸(shu)送(song)(song)距(ju)離、輸(shu)送(song)(song)管(guan)道的直徑、風速等(deng)。一(yi)般來說，對(dui)于(yu)(yu)一(yi)些較輕的物(wu)料(liao)，如(ru)水泥、石灰等(deng)，負壓(ya)氣(qi)力輸(shu)送(song)(song)輸(shu)送(song)(song)高(gao)度(du)可達50米甚至更高(gao)。但對(dui)于(yu)(yu)一(yi)些比較重的物(wu)料(liao)，如(ru)鈣粉、鍋爐灰等(deng)，由(you)于(yu)(yu)密度(du)大，其輸(shu)送(song)(song)高(gao)度(du)較低，一(yi)般在(zai)10-15米左右。

       另外需(xu)要注意的(de)是，在(zai)負(fu)壓(ya)輸(shu)送(song)(song)(song)中(zhong)，輸(shu)送(song)(song)(song)高(gao)度越(yue)高(gao)，對輸(shu)送(song)(song)(song)氣流(liu)的(de)要求越(yue)高(gao)，輸(shu)送(song)(song)(song)阻力(li)也越(yue)大。需(xu)要加(jia)大壓(ya)縮空氣的(de)流(liu)量(liang)和壓(ya)力(li)，增加(jia)能耗，又會增加(jia)設備成(cheng)本。因此，在(zai)實際應用中(zhong)，需(xu)要綜合考慮物料的(de)性質、輸(shu)送(song)(song)(song)距(ju)離、輸(shu)送(song)(song)(song)管道的(de)直(zhi)徑等，確定(ding)合適的(de)輸(shu)送(song)(song)(song)高(gao)度和輸(shu)送(song)(song)(song)方式，以實現節(jie)能減料輸(shu)送(song)(song)(song)。
