U型螺(luo)旋(xuan)輸(shu)(shu)(shu)送機(ji)是(shi)利(li)用旋(xuan)轉的螺(luo)旋(xuan)將物料沿著固定的機(ji)殼(ke)槽推(tui)移(yi)而進行輸(shu)(shu)(shu)送工(gong)作。螺(luo)旋(xuan)輸(shu)(shu)(shu)送機(ji)特點是(shi)密封傳動，結構簡(jian)單。螺(luo)旋(xuan)輸(shu)(shu)(shu)送機(ji)是(shi)冶金、建材、化工(gong)、糧食及機(ji)械(xie)加工(gong)等部門廣泛應用的一種連續(xu)輸(shu)(shu)(shu)送設備。

U型螺(luo)(luo)(luo)旋(xuan)(xuan)輸(shu)(shu)(shu)送(song)(song)機能輸(shu)(shu)(shu)送(song)(song)粉狀、粒狀和(he)(he)小(xiao)塊狀物(wu)料如面粉、谷物(wu)和(he)(he)卵(luan)石等。散料在(zai)(zai)(zai)自重和(he)(he)機殼的(de)摩(mo)擦力作(zuo)用(yong)下堆積在(zai)(zai)(zai)槽的(de)下部，不隨葉片(pian)旋(xuan)(xuan)轉(zhuan)而被葉片(pian)推動前進。輸(shu)(shu)(shu)送(song)(song)干燥的(de)、粘(zhan)性小(xiao)的(de)粉、粒狀物(wu)料時(shi)用(yong)實體葉片(pian)螺(luo)(luo)(luo)旋(xuan)(xuan)；輸(shu)(shu)(shu)送(song)(song)粘(zhan)性較大的(de)或(huo)塊狀物(wu)料時(shi)用(yong)帶(dai)式葉片(pian)螺(luo)(luo)(luo)旋(xuan)(xuan)；輸(shu)(shu)(shu)送(song)(song)易結團物(wu)料時(shi)用(yong)槳(jiang)式葉片(pian)螺(luo)(luo)(luo)旋(xuan)(xuan)，這種螺(luo)(luo)(luo)旋(xuan)(xuan)除推動物(wu)料外還有打散結團的(de)作(zuo)用(yong)。輸(shu)(shu)(shu)送(song)(song)距(ju)離一般在(zai)(zai)(zai)70米以(yi)內，螺(luo)(luo)(luo)旋(xuan)(xuan)的(de)投影直徑在(zai)(zai)(zai)1250毫米以(yi)下，輸(shu)(shu)(shu)送(song)(song)傾角(jiao)小(xiao)于20°，輸(shu)(shu)(shu)送(song)(song)能力大。螺(luo)(luo)(luo)旋(xuan)(xuan)輸(shu)(shu)(shu)送(song)(song)機可在(zai)(zai)(zai)多處裝(zhuang)料、卸(xie)料，密(mi)封性好，可輸(shu)(shu)(shu)送(song)(song)溫度低于200℃的(de)物(wu)料。

U型螺旋輸(shu)送(song)(song)機采用DIN15261-1986工藝(yi)標準，設計(ji)制(zhi)造   符(fu)合(he)《螺旋輸(shu)送(song)(song)機》標準。整機設計(ji)構(gou)造較為(wei)簡單，由U型槽、進料口、法蘭、驅(qu)動裝置、襯板(ban)、上蓋等部件組(zu)成(cheng)。橫(heng)截面(mian)積小，機體的密封性能(neng)好，設備的操作(zuo)簡單，操作(zuo)人員無   隱患，U型輸(shu)送(song)(song)機的制(zhi)造成(cheng)本較低，并(bing)且該(gai)輸(shu)送(song)(song)機的能(neng)源消耗(hao)較大。

U型螺旋輸(shu)(shu)送(song)(song)機有多種輸(shu)(shu)送(song)(song)方式，可以(yi)水平輸(shu)(shu)送(song)(song)、傾斜輸(shu)(shu)送(song)(song)、垂直輸(shu)(shu)送(song)(song)等甚(shen)至可以(yi)幾種形式組(zu)合使用。該輸(shu)(shu)送(song)(song)機中間吊軸(zhou)承采(cai)用滾(gun)動(dong)、滑動(dong)可互換的兩種結構(gou)。該螺旋輸(shu)(shu)送(song)(song)機可以(yi)和其它輸(shu)(shu)送(song)(song)設備聯合工(gong)作(zuo)。并可與其他(ta)輸(shu)(shu)送(song)(song)設備或(huo)工(gong)作(zuo)裝置配合使用。

U型螺旋輸送機的分類介紹：

U型螺旋輸(shu)送機按螺旋輸(shu)送機驅動方式(shi)分類

A、U型(xing)螺旋輸送機長度小于35m時，為單軸驅(qu)動螺旋。

B、U型螺旋輸(shu)送機長度(du)大于35m時，為(wei)雙(shuang)軸(zhou)驅(qu)動(dong)螺旋。

U型(xing)螺(luo)旋(xuan)(xuan)輸(shu)送機按(an)螺(luo)旋(xuan)(xuan)輸(shu)送機材質分(fen)類

A、普(pu)通碳(tan)鋼U型螺旋輸送機-主(zhu)要適用于水(shui)泥，煤炭、石料、等磨損較(jiao)大，對物料沒要求(qiu)的行業。
