WLS型螺旋輸送機分為多種直徑的型號，無軸螺旋輸送機主要是用于容易卡料的工況下使用。因為殼體與葉片之(zhi)間(jian)增加(jia)了耐(nai)磨(mo)襯板。

螺(luo)(luo)旋(xuan)(xuan)輸(shu)(shu)(shu)送(song)(song)機為了防卡(ka)的話，就(jiu)(jiu)可以做成無軸的，它(ta)的輸(shu)(shu)(shu)送(song)(song)量和輸(shu)(shu)(shu)送(song)(song)距(ju)離以及(ji)輸(shu)(shu)(shu)送(song)(song)角度(du)不會變(bian)，但是(shi)我們考慮到無軸螺(luo)(luo)旋(xuan)(xuan)輸(shu)(shu)(shu)送(song)(song)機的輸(shu)(shu)(shu)送(song)(song)方式(shi)就(jiu)(jiu)是(shi)靠(kao)著螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)(pian)的推動來(lai)進行(xing)輸(shu)(shu)(shu)送(song)(song)的，所以螺(luo)(luo)旋(xuan)(xuan)輸(shu)(shu)(shu)送(song)(song)機的葉(xie)(xie)片(pian)(pian)厚度(du)，以及(ji)螺(luo)(luo)距(ju)及(ji)螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)(pian)的內徑(jing)和外徑(jing)設計。
