class="title">詳細(xì)說(shuō)明</p><div id="9jpxthv" class="box"><p><p> 螺桿泵定子磨損的原因有哪些？螺桿泵一般都是用鋼材作轉(zhuǎn)子，橡膠做定子。而制作定子的材料一般是丁腈橡膠，原因是丁腈橡膠具有很好的耐油性。轉(zhuǎn)子因?yàn)槭褂玫氖卿摬乃员认鹉z耐磨，因此注定了螺桿泵的失效形式主要是縣膠套的磨損。也就是說(shuō)，定子的使用壽命和螺桿泵的使用壽命緊密相關(guān)，想要延長(zhǎng)定子的使用壽命就要想辦法解決橡膠的磨損問(wèn)題。濕磨粒磨損 </p> <p> 濕磨粒磨損是顆粒磨損的一種情況，還有一種名為分干磨粒磨損。二者區(qū)分如下：濕磨粒磨損就是在磨粒和橡膠之間存在液體介質(zhì)，而干磨粒磨損就是在磨粒和橡膠之間不存在液體介質(zhì)。因?yàn)槁輻U泵的工作環(huán)境，原裝螺桿泵廠(chǎng)家直供，造成螺桿泵顆粒磨損的主要是濕磨粒磨損。 </p> <p> 疲勞磨損 </p> <p> 疲勞磨損是定子橡膠與轉(zhuǎn)子上圓鈍的對(duì)偶表面之間的摩擦力和接觸應(yīng)力都不太大的條件下產(chǎn)生的。這種磨損和磨粒磨損在很多方面都很相似，有的學(xué)者把疲勞磨損看作磨粒磨損的一種形式，原裝螺桿泵廠(chǎng)家直供，原裝螺桿泵廠(chǎng)家直供，即圓鈍磨粒磨損。但是與磨粒磨損相比，疲勞磨損是一種低強(qiáng)度的磨損。 </p> <p> <br /> 由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。原裝螺桿泵廠(chǎng)家直供</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="原裝螺桿泵廠(chǎng)家直供,螺桿泵"

style="text-indent:25px">由于各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合，在泵的吸入口和排出口之間，就會(huì)被分隔成一個(gè)或多個(gè)密封空間。隨著螺桿的轉(zhuǎn)動(dòng)和嚙合，這些密封空間在泵的吸入端不斷形成，將吸入室中的液體封入其中，并自吸入室沿螺桿軸向連續(xù)地推移至排出端，將封閉在各空間中的液體不斷排出，猶如一螺母在螺紋回轉(zhuǎn)時(shí)被不斷向前推進(jìn)的情形那樣，這就是G型污泥螺桿泵的基本工作原理。污泥螺桿泵工作時(shí)，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間，當(dāng)主動(dòng)螺桿旋轉(zhuǎn)時(shí)，螺桿泵密封容積在螺牙的擠壓下提高螺桿泵壓力，并沿軸向移動(dòng)。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。污泥螺桿泵特點(diǎn)為：螺桿泵損失小，經(jīng)濟(jì)性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動(dòng)機(jī)直聯(lián)。污泥螺桿泵可以輸送潤(rùn)滑油，輸送燃油，輸送各種油類(lèi)及高分子聚合物，用于輸送黏稠液體。湛江正規(guī)螺桿泵單螺桿泵一泵多用可以輸送不同粘度的介質(zhì).</p><div

在啟動(dòng)泵前，先將要輸送的介質(zhì)注入泵的吸入腔內(nèi)(若介質(zhì)濃度高，稀釋后注入)。以確保潤(rùn)滑橡膠定子。泵停止運(yùn)轉(zhuǎn)時(shí)，應(yīng)留有足夠的介質(zhì)在吸入腔內(nèi)。用記在設(shè)計(jì)管道時(shí)應(yīng)予以專(zhuān)門(mén)考慮。 </p> <p> 2、污泥螺桿泵不能在閥門(mén)關(guān)閉時(shí)工作，以避免容積泵的壓力急劇升高而造成管道破裂及泵的損壞。尤其在輸送危險(xiǎn)介質(zhì)時(shí)，安裝壓力開(kāi)關(guān)等安全裝置是尤其重要的。 </p> <p> 3、泵應(yīng)瞬時(shí)通電，確認(rèn)泵的轉(zhuǎn)身與所示的方向相同。 </p> <p> 4、啟動(dòng)前，再一次檢查，多種管道閥門(mén)的開(kāi)啟關(guān)閉情況。無(wú)誤時(shí)，方可開(kāi)機(jī)。 </p> <p> 5、輸送易沉淀，易固化介質(zhì)，應(yīng)定期清洗泵及管線(xiàn)。 </p> <p> 6、對(duì)已存放二年以上的泵，應(yīng)對(duì)泵內(nèi)所有的橡膠進(jìn)行更換(包括定子)，發(fā)確保泵的運(yùn)轉(zhuǎn)正常及安全，從而延長(zhǎng)泵的使用壽命。 </p> <p> 維護(hù)與保養(yǎng) </p> <p> <br /> </p><p> 單螺桿泵的嚙合副型線(xiàn)，近十多年來(lái)國(guó)外有些廠(chǎng)商開(kāi)發(fā)雙頭螺旋的轉(zhuǎn)子和三頭內(nèi)嚙合螺旋的定子相嚙合的單螺桿泵進(jìn)展很快，個(gè)別的廠(chǎng)商已發(fā)展到大批量生產(chǎn)和銷(xiāo)售。我國(guó)也有少數(shù)制造廠(chǎng)進(jìn)行研制，目前尚處在開(kāi)發(fā)階段。 </p> <p> 雙頭螺旋轉(zhuǎn)子和三頭內(nèi)螺旋定子構(gòu)成的單螺桿泵與單頭螺旋轉(zhuǎn)子和雙頭內(nèi)螺旋定子構(gòu)成的單螺桿泵相比較，有著如下的優(yōu)點(diǎn)： </p> <p> 1）在相同轉(zhuǎn)速和相同橫向尺寸的螺旋段情況下，有著較大的流量，或在相同激量時(shí)導(dǎo)程T的尺寸較小。 </p> <p> 2）由于轉(zhuǎn)子每轉(zhuǎn)一周，密封腔數(shù)為2×3 =6,而單頭螺旋轉(zhuǎn)子和雙頭內(nèi)螺旋定子的泵，密封腔數(shù)為1×2 =2,因此其流量脈動(dòng)和壓力脈動(dòng)較小。 </p> <p> 3 ）轉(zhuǎn)子的偏心距較小，因此噪聲和振動(dòng)也隨之降低，并允許采用較高的轉(zhuǎn) 速，或在相同的轉(zhuǎn)速和相同流量時(shí)，吸上性能更好。 </p> <p> 4）容積效率和機(jī)械效率也更高。 </p> <p> 5)起動(dòng)力距較小。 </p> <p> 6)壽命更長(zhǎng)。 </p> <p> <br /> 提高總效率的技術(shù)包括保持高容積效率.</p><div style="width:100%;text-align:
