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(yao)是用于容易卡料的工況下使用。因為(wei)殼體與(yu)葉(xie)片(pian)之間增(zeng)加了耐磨襯(chen)板(ban)。

螺旋(xuan)(xuan)輸(shu)(shu)送(song)(song)(song)機(ji)(ji)為了防(fang)卡的(de)(de)(de)話，就(jiu)(jiu)可以(yi)(yi)做成無(wu)軸的(de)(de)(de)，它的(de)(de)(de)輸(shu)(shu)送(song)(song)(song)量和輸(shu)(shu)送(song)(song)(song)距(ju)離以(yi)(yi)及(ji)(ji)輸(shu)(shu)送(song)(song)(song)角(jiao)度不會變，但是我們考慮到(dao)無(wu)軸螺旋(xuan)(xuan)輸(shu)(shu)送(song)(song)(song)機(ji)(ji)的(de)(de)(de)輸(shu)(shu)送(song)(song)(song)方式就(jiu)(jiu)是靠著(zhu)螺旋(xuan)(xuan)葉(xie)片的(de)(de)(de)推動來進(jin)行輸(shu)(shu)送(song)(song)(song)的(de)(de)(de)，所以(yi)(yi)螺旋(xuan)(xuan)輸(shu)(shu)送(song)(song)(song)機(ji)(ji)的(de)(de)(de)葉(xie)片厚度，以(yi)(yi)及(ji)(ji)螺距(ju)及(ji)(ji)螺旋(xuan)(xuan)葉(xie)片的(de)(de)(de)內徑和外徑設計。
