管鏈式粉體輸送機是在(zai)密閉管道(dao)內(nei)(nei)(nei)，以(yi)鏈(lian)(lian)片(pian)為傳動(dong)構件帶動(dong)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)沿管道(dao)運動(dong)。當(dang)水(shui)平輸送(song)時(shi)(shi)(shi)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)顆粒受到鏈(lian)(lian)片(pian)在(zai)運動(dong)方(fang)向(xiang)的(de)推(tui)力(li)。當(dang)料(liao)(liao)(liao)(liao)(liao)(liao)層間(jian)(jian)的(de)內(nei)(nei)(nei)摩擦(ca)力(li)大于物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)與(yu)管壁(bi)的(de)外摩擦(ca)力(li)時(shi)(shi)(shi)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)就(jiu)隨鏈(lian)(lian)片(pian)向(xiang)前運動(dong)，形成穩(wen)定的(de)料(liao)(liao)(liao)(liao)(liao)(liao)流(liu)；當(dang)垂直(zhi)輸送(song)時(shi)(shi)(shi)，管內(nei)(nei)(nei)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)顆粒受鏈(lian)(lian)片(pian)向(xiang)上(shang)推(tui)力(li)，因為下部給料(liao)(liao)(liao)(liao)(liao)(liao)阻止上(shang)部物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)下滑，產生(sheng)了(le)橫(heng)向(xiang)側壓力(li)，所以(yi)增強了(le)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)的(de)內(nei)(nei)(nei)摩擦(ca)力(li)，當(dang)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)間(jian)(jian)的(de)內(nei)(nei)(nei)摩擦(ca)力(li)大于物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)與(yu)管內(nei)(nei)(nei)壁(bi)外摩擦(ca)力(li)及(ji)物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)自重時(shi)(shi)(shi)，物(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)就(jiu)隨鏈(lian)(lian)片(pian)向(xiang)上(shang)輸送(song)，形成連續(xu)料(liao)(liao)(liao)(liao)(liao)(liao)流(liu)。
