特點和用途
管式(shi)螺(luo)旋(xuan)輸送機具有(you)著以下優點：
1）構造較(jiao)為簡單，成(cheng)本費較(jiao)低[4]。
2）運行(xing)可靠，維護保養(yang)管理方法簡單(dan)。
3）規格緊密，斷面(mian)規格小(xiao)，占地總(zong)面(mian)積小(xiao)。在海港的卸車(che)卸船工作(zuo)中易進出艙口、車(che)廂。
4）能達到密封性傳(chuan)輸，有助于傳(chuan)輸易飛揚的(de)、熾熱的(de)及味道刺鼻(bi)的(de)材(cai)料，可減(jian)小對環境的(de)生態破壞(huai)，有所(suo)改善(shan)海港工人的(de)工作條件。
5）裝載卸載便捷(jie)。水平螺(luo)旋(xuan)(xuan)輸送機(ji)可在(zai)其傳輸機(ji)路上的任一(yi)點(dian)裝載卸載；對豎(shu)直螺(luo)旋(xuan)(xuan)輸送機(ji)配置(zhi)相對螺(luo)旋(xuan)(xuan)式取料(liao)裝置(zhi)可具有著優良的取料(liao)特(te)性。
6）能反向傳輸(shu)，也(ye)能夠讓一(yi)臺輸(shu)送設備同一(yi)時間向兩個方(fang)向傳輸(shu)材料，即集向中心(xin)或遠離中心(xin)。
7）單位耗能較大。
8）材(cai)料在傳輸全過程中(zhong)非常容易磨(mo)(mo)碎及磨(mo)(mo)損(sun)(sun)，螺旋葉片和料槽的(de)磨(mo)(mo)損(sun)(sun)也較為嚴重(zhong)。
結構特征
（1）螺(luo)(luo)旋(xuan)輸(shu)送機(ji)的螺(luo)(luo)旋(xuan)葉(xie)(xie)片(pian)(pian)有實物螺(luo)(luo)旋(xuan)面(mian)型、帶式(shi)螺(luo)(luo)旋(xuan)面(mian)型及葉(xie)(xie)片(pian)(pian)螺(luo)(luo)旋(xuan)面(mian)型三種。實物螺(luo)(luo)旋(xuan)面(mian)被稱(cheng)作s制(zhi)法，其(qi)螺(luo)(luo)旋(xuan)式(shi)節(jie)(jie)距GX型為葉(xie)(xie)片(pian)(pian)直(zhi)經(jing)的0.8倍(bei)，LS型螺(luo)(luo)旋(xuan)輸(shu)送機(ji)主(zhu)要運用(yong)于傳輸(shu)粉(fen)末狀和(he)顆粒狀材(cai)料(liao)。帶式(shi)螺(luo)(luo)旋(xuan)面(mian)又稱(cheng)D制(zhi)法，其(qi)螺(luo)(luo)旋(xuan)式(shi)節(jie)(jie)距與螺(luo)(luo)旋(xuan)葉(xie)(xie)片(pian)(pian)直(zhi)經(jing)一樣，主(zhu)要運用(yong)于傳輸(shu)粉(fen)末狀及小(xiao)塊材(cai)料(liao)。葉(xie)(xie)片(pian)(pian)式(shi)螺(luo)(luo)旋(xuan)面(mian)用(yong)途較(jiao)少，主(zhu)要運用(yong)于傳輸(shu)黏(nian)度較(jiao)大(da)和(he)可(ke)壓縮性材(cai)料(liao)，在傳輸(shu)全(quan)過程中，同一時間完成攪拌、混合等工序，其(qi)螺(luo)(luo)旋(xuan)式(shi)節(jie)(jie)距約為螺(luo)(luo)旋(xuan)葉(xie)(xie)片(pian)(pian)直(zhi)經(jing)的1.2倍(bei)。
（2）螺旋(xuan)輸(shu)送(song)機的螺旋(xuan)葉片有左旋(xuan)與右旋(xuan)二種旋(xuan)向(xiang)。
（3）螺(luo)旋輸(shu)(shu)送(song)(song)機(ji)的類型有水平固定式螺(luo)旋輸(shu)(shu)送(song)(song)機(ji)、豎直(zhi)式螺(luo)旋輸(shu)(shu)送(song)(song)機(ji)。水平固定式螺(luo)旋輸(shu)(shu)送(song)(song)機(ji)是最常用的種(zhong)型式。
