3、螺桿泵的螺桿在機筒內轉動，物料與二者的摩擦，使螺桿與機筒的工作表面逐漸磨損：螺桿直徑逐漸縮小，正規(guī)螺桿泵詢問報價，機筒的內孔直徑逐漸加大。這樣，螺桿與機筒的配合直徑間隙，隨著二者的逐漸磨損而一點點加大?？墒牵捎跈C筒前面機頭和分流板的阻力沒有改變，這就增加了被擠塑物料前進時的漏流量，即物料從直徑間隙處向進料方向流動量增加。結果使塑膠機械生產量下降。這種現象又使物料在機筒內停留時間增加，造成物料分解。如果是聚乙烯，分解產生的氯化氫氣體加強了對螺桿和機筒的腐蝕。 </p> <p> <br /> </p> <p> 4、物料中如有碳酸鈣和玻璃纖維等填充料，能加快螺桿和機筒的磨損。 </p> <p> <br /> </p> <p> 5、由于物料沒有塑化均勻，或是有金屬異物混入料中，使螺桿轉動扭矩力突然增加，這種扭矩超出螺桿的強度極限，正規(guī)螺桿泵詢問報價，使螺桿扭斷，正規(guī)螺桿泵詢問報價。這是一種非常規(guī)***損壞。 </p> <p>

1、每種塑料，都有一個理想塑化的加工溫度范圍，應該控制料筒加工溫度，使之接近這個溫度范圍。粒狀塑料從料斗進入料筒，首先會到達加料段，在加料段必然會出現干性磨擦，當這些塑料受熱不足，熔融不均時，很易造成料筒內壁及螺桿表面磨損增大。同樣，在壓縮段和均化段，如果塑料的熔融狀態(tài)紊亂不均，也會造成磨損增快。 </p> <p> 2、轉速應調校得當。由于部分塑料加有強化劑，如玻璃纖維、礦物質或其他填充料。這些物質對金屬材質的磨擦力往往比熔融塑料的大得多。在注塑這些塑料時，如果用高的轉速成，則在提高對塑料的剪切力的同時，亦將令強化相應地產生更多被撕碎的纖維，被撕碎的纖維含有鋒利末端，令磨損力大為增加。無機礦物質在金屬表面高速滑行時，其刮削作用也不小。所以轉速不宜調得太高。 </p> <p> <br /> </p><p> 單螺桿泵的驅動優(yōu)缺點介紹，單螺桿泵，顧名思義，意味著泵中只有一個螺桿。繼續(xù)使用中國螺桿泵行業(yè)的習慣，單螺桿泵的螺桿被稱為轉子，而螺桿襯套稱為定子，由外部動力源驅動的轉子是EngA。通過定子的Ge形成一個密封腔，在吸入室和排出室之間分離，從而使泵能夠有效地工作。 </p> <p> <br /> </p> <p> 目前，世界各國生產的單螺桿泵都是轉子和定子的嚙合副。絕大多數產品仍與單螺旋轉子定子和雙頭內螺旋嚙合，過去10多年來，國外一些廠家開發(fā)了雙螺桿轉子和三內嚙合螺旋定子，單螺桿泵正在運行。迅速發(fā)展，一些廠家已經發(fā)展到批量生產和銷售，在中國也有一些制造廠，目前仍處于發(fā)展階段。 </p> <p> <br /> </p> <p> <br />
