class="title">詳細(xì)說(shuō)明</p><div id="hrjgipm" class="box"><p><p> G型單螺桿泵螺桿軸磨損五點(diǎn)原因： </p> <p> 1、每種塑料，都有一個(gè)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(gè)溫度范圍。粒狀塑料從料斗進(jìn)入料筒，首先會(huì)到達(dá)加料段，原裝螺桿泵性價(jià)比高，原裝螺桿泵性價(jià)比高，在加料段必然會(huì)出現(xiàn)干性磨擦，原裝螺桿泵性價(jià)比高，當(dāng)這些塑料受熱不足，熔融不均時(shí)，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(huì)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(qiáng)化劑，如玻璃纖維、礦物質(zhì)或其他填充料。這些物質(zhì)對(duì)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(shí)，如果用高的轉(zhuǎn)速成，則在提高對(duì)塑料的剪切力的同時(shí)，亦將令強(qiáng)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(wú)機(jī)礦物質(zhì)在金屬表面高速滑行時(shí)，其刮削作用也不小。所以轉(zhuǎn)速不宜調(diào)得太高。 </p> <p> <br /> 單螺桿泵流量均勻壓力穩(wěn)定，低轉(zhuǎn)速時(shí)更為明顯.原裝螺桿泵性價(jià)比高</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="原裝螺桿泵性價(jià)比高,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906572265/7384951.jpg"></div><p style="text-indent:25px">螺桿泵的腐蝕與防護(hù)，螺桿泵輸送的液體種類很多，液體的性質(zhì)和螺桿泵的操作條件也是千差萬(wàn)別的，如液體的溫度可高達(dá)幾百度，壓力可達(dá)幾十兆帕，有的介質(zhì)呈酸性，有的介質(zhì)呈堿性?有的介質(zhì)腐蝕性強(qiáng)，有的介質(zhì)腐蝕性弱等。為了滿足以上要求，除了采用不同類型的螺桿泵以外，還要了解不同的液體在各種條件下對(duì)金屬材料的腐蝕情況，從而針對(duì)不同的液體來(lái)選擇合適的耐腐蝕螺桿泵用于各類化工生產(chǎn)工藝流程中去，并且采取相應(yīng)的防腐措施以延長(zhǎng)螺桿泵的使用壽命，這也是石油化工用螺桿泵的一個(gè)非常重要的問(wèn)題。多數(shù)螺桿泵是由金屬材料制造的，金屬材料腐蝕的規(guī)律比較復(fù)雜，不同的材料在同一種介質(zhì)中的腐蝕情況各不相同，同一種材料在不同介質(zhì)中的腐蝕情況也大相徑庭，比如碳鋼在稀***中腐蝕速度很快，但在濃***中卻相當(dāng)穩(wěn)定；普通的18-8型奧氏體不銹鋼能耐硝酸、冷磷酸、許多鹽類及堿溶液、水和蒸汽、石油產(chǎn)品等化學(xué)介質(zhì)的腐蝕，但是對(duì)***、鹽酸、氫氟酸、鹵素、草酸等的化學(xué)穩(wěn)定性比較差；鋁在稀***和發(fā)煙***中穩(wěn)定，在中等和高濃度的***中卻不穩(wěn)定。因此，必須首先了解金屬腐蝕的原因和種類，才能針對(duì)特定的化工物料，正確選用合適的耐腐蝕螺桿泵并采取合理的防腐措施。本地螺桿泵生產(chǎn)廠商嚴(yán)格檢查待裝零件的質(zhì)量，清洗是否干凈，外表是否損壞。</p><div

1.螺桿泵因氣蝕而導(dǎo)致的問(wèn)題：泵產(chǎn)生氣蝕的原因主要有泵入口管阻大、輸送介質(zhì)氣相較多、灌泵不充分、泵入口能頭不夠等原因。氣蝕對(duì)泵的危害比較大，發(fā)生氣蝕時(shí)泵劇烈振動(dòng)，平衡嚴(yán)重破壞，將導(dǎo)致泵軸承、轉(zhuǎn)子或葉輪損壞。這是螺桿泵故障發(fā)生的常見(jiàn)原因。 </p> <p> <br /> </p><p> 3、螺桿泵的螺桿在機(jī)筒內(nèi)轉(zhuǎn)動(dòng)，物料與二者的摩擦，使螺桿與機(jī)筒的工作表面逐漸磨損：螺桿直徑逐漸縮小，機(jī)筒的內(nèi)孔直徑逐漸加大。這樣，螺桿與機(jī)筒的配合直徑間隙，隨著二者的逐漸磨損而一點(diǎn)點(diǎn)加大?？墒?，由于機(jī)筒前面機(jī)頭和分流板的阻力沒(méi)有改變，這就增加了被擠塑物料前進(jìn)時(shí)的漏流量，即物料從直徑間隙處向進(jìn)料方向流動(dòng)量增加。結(jié)果使塑膠機(jī)械生產(chǎn)量下降。這種現(xiàn)象又使物料在機(jī)筒內(nèi)停留時(shí)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(qiáng)了對(duì)螺桿和機(jī)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(jī)筒的磨損。 </p> <p> <br /> </p> <p> 5、由于物料沒(méi)有塑化均勻，或是有金屬異物混入料中，使螺桿轉(zhuǎn)動(dòng)扭矩力突然增加，這種扭矩超出螺桿的強(qiáng)度極限，使螺桿扭斷。這是一種非常規(guī)***損壞。 </p> <p> <br /> 對(duì)采用機(jī)械密封的，則要非常小心翼翼地進(jìn)行，否則極易造成動(dòng)、靜環(huán)的破碎。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="原裝螺桿泵性價(jià)比高,螺桿泵"

不同金屬在電解質(zhì)溶液中的電位不同，它們之間會(huì)產(chǎn)生電位差；同一金屬由于本身**不均勻在電解質(zhì)溶液中也有可能產(chǎn)生電位差；同一金屬在電解質(zhì)溶液中所處的環(huán)境條件有差別（如濃度、溫度和應(yīng)力差別等）也會(huì)產(chǎn)生電位差。而在酸、堿、鹽等電解質(zhì) </p> <p> <br /> </p> <p> 溶液中都存在著帶正電荷的陽(yáng)離子和帶負(fù)電荷的陰離子，電位差成了電解質(zhì)溶液中離子移動(dòng)的推動(dòng)力，離子移動(dòng)到電極上得失電子的同時(shí)便會(huì)產(chǎn)生金屬的腐蝕，并同時(shí)產(chǎn)生電流。因此，電化學(xué)腐蝕是由于金屬發(fā)生腐蝕電池作用引起的。如果將兩種電位不同的金屬（如銅和鋅）用導(dǎo)線連接起來(lái)，放在電解質(zhì)溶液（如?。?SO4溶液）中,這樣就構(gòu)成了導(dǎo)電回路，回路中的電子將從低電位的鋅流向高電位的銅，電子的移動(dòng)產(chǎn)生電流，形成腐蝕電池。鋅不斷失去電子，變?yōu)殇\離子進(jìn)人溶液，鋅電極成為腐蝕電池的極，出現(xiàn)腐蝕；銅電極成為腐蝕電池的陰極而被保護(hù)，溶液中的H＋不斷移動(dòng)到銅電極上得到電子而析出H2。
