螺桿泵業(yè)計量螺桿泵配件選型指南，隨著工業(yè)化和城市化的進程逐步加快，螺桿泵閥制造業(yè)的需求越來越大，發(fā)展前景異常廣闊。螺桿泵閥產(chǎn)業(yè)是一個龐大的產(chǎn)業(yè)群體，在國民經(jīng)濟建設(shè)中發(fā)揮著重要的作用。目前，我國螺桿泵閥行業(yè)低端領(lǐng)域已基本實現(xiàn)國產(chǎn)化，中**領(lǐng)域亦憑借著成本、服務(wù)等優(yōu)勢實現(xiàn)著對進口產(chǎn)品的逐步替代，并致力于螺桿泵閥行業(yè)的國際化競爭中。在過去的幾十年中，明杰螺桿泵業(yè)的螺桿泵閥產(chǎn)品經(jīng)過不斷的技術(shù)更新、新品開發(fā)和品牌創(chuàng)新，一直保持著業(yè)界計量螺桿泵產(chǎn)品技術(shù)的前端地位。在技術(shù)的應(yīng)用，產(chǎn)品性能范圍、應(yīng)用領(lǐng)域、產(chǎn)品質(zhì)量、可靠性、效率、噪聲、振動、外觀等多方面突出優(yōu)勢受到相關(guān)行業(yè)采購商的***關(guān)注與青睞。 </p> <p> 螺桿泵定義計量螺桿泵是一種可以滿足各種嚴(yán)格的工藝流程需要，流量可以在0-**范圍內(nèi)無級調(diào)節(jié)，用來輸送液體（特別是腐蝕性液體）一種特殊容積螺桿泵。計量螺桿泵也稱定量螺桿泵或比例螺桿泵，計量螺桿泵屬于往復(fù)式容積螺桿泵，用于精確計量的，通常要求計量螺桿泵的穩(wěn)定性精度不超過±1%。隨著現(xiàn)代化工業(yè)朝著自動化操作、遠(yuǎn)距離自動控制這一形勢的不斷發(fā)展，計量螺桿泵的配套性強、適應(yīng)介質(zhì)（液體）***的優(yōu)勢尤為顯得突出。

src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906445312/5967838.jpg"></div><p> G型單螺桿泵螺桿軸磨損五點原因： </p> <p> 1、每種塑料，都有一個理想塑化的加工溫度范圍，應(yīng)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(xiàn)干性磨擦，當(dāng)這些塑料受熱不足，熔融不均時，很易造成料筒內(nèi)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(zhuǎn)速應(yīng)調(diào)校得當(dāng)。由于部分塑料加有強化劑，如玻璃纖維、礦物質(zhì)或其他填充料。這些物質(zhì)對金屬材質(zhì)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(zhuǎn)速成，則在提高對塑料的剪切力的同時，亦將令強化相應(yīng)地產(chǎn)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(zhì)在金屬表面高速滑行時，其刮削作用也不小。所以轉(zhuǎn)速不宜調(diào)得太高。 </p> <p> <br /> </p><p> 四、避免斷料 </p> <p> <br /> </p> <p> 螺桿泵決不允許在斷料的情形下運轉(zhuǎn)，一經(jīng)發(fā)生，橡膠定子由于干摩擦，瞬間產(chǎn)生高溫而燒壞，所以，粉碎機完好，格柵暢通是螺桿泵正常運轉(zhuǎn)的必要條件之一，為此，有些螺桿泵還在泵身上安裝了斷料停機裝置，當(dāng)發(fā)生斷料時，由于螺桿泵其有自吸功能的特性，腔體內(nèi)會產(chǎn)生真空，真空裝置會使螺桿泵停止運轉(zhuǎn)。五、保持恒定的出口壓力 </p> <p> <br /> </p> <p> 螺桿泵是一種容積式回轉(zhuǎn)泵，當(dāng)出口端受阻以后，壓力會逐漸升高，以至于超過預(yù)定的壓力值。此時電機負(fù)荷急劇增加。傳動機械相關(guān)零件的負(fù)載也會超出設(shè)計值，嚴(yán)重時會發(fā)生電機燒毀、傳動零件斷裂。為了避免螺桿泵損壞，一般會在螺桿泵出口處會安裝回油閥，用以穩(wěn)定出口壓力，保持泵的正常運轉(zhuǎn)。單螺桿泵的安裝位置可以任意傾斜.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河源螺桿泵推薦企業(yè),螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906074218/7463302.jpg"></div><p> 3、螺桿泵的螺桿在機筒內(nèi)轉(zhuǎn)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，機筒的內(nèi)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。可是，由于機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(jié)果使塑膠機械生產(chǎn)量下降。這種現(xiàn)象又使物料在機筒內(nèi)停留時間增加，造成物料分解。如果是聚乙烯，分解產(chǎn)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(zhuǎn)動扭矩力突然增加，這種扭矩超出螺桿的強度極限，使螺桿扭斷。這是一種非常規(guī)***損壞。 </p> <p> <br />
