擠出機(jī)常見問題及處理方法之螺桿發(fā)熱現(xiàn)象。

1、絞刀嚴(yán)重磨損。絞刀與泥缸內(nèi)壁的間隙太大,或絞刀葉片的螺旋角不對,應(yīng)該在更換絞刀時應(yīng)注意保持其間隙為3~5mm,以及應(yīng)按照設(shè)計(jì)的角度制作絞刀葉片。

2、 絞刀葉片的表面過于粗糙,泥料和葉片的摩擦力太大,因此在堆焊絞刀時不要成組堆焊,一次全部換完,應(yīng)循序漸進(jìn),分批更換,以確保順利出磚。

3 、泥缸壁襯套嚴(yán)重磨損。絞刀葉片與泥缸壁間間隙過大,導(dǎo)致泥料在泥缸里的旋轉(zhuǎn)運(yùn)動太多,泥料出不來,也進(jìn)不去。這時應(yīng)更換新的泥缸襯套,或在其襯套內(nèi)壁裝上若干根平行或傾斜于軸向的肋條,以代替被磨掉的來復(fù)槽,阻止泥料無效的回轉(zhuǎn),增加其有效的擠出。

4 、壓泥刀板與絞刀的間隙過大壓不下泥料,此時應(yīng)調(diào)整或補(bǔ)焊、更新刀板,使其與絞刀葉片的間隙小于10mm。
