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。可是，肇慶螺桿泵制造廠家，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，肇慶螺桿泵制造廠家，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。

src="http://tyunfile.71360.com/UploadFile/qunxun/637211876905917968/581422.jpg"></div><p> 給大家介紹螺桿泵保養(yǎng)技巧： </p> <p> 1、經(jīng)常加脂，電動(dòng)油桶泵為高速運(yùn)轉(zhuǎn)，潤(rùn)滑脂易于揮發(fā)，故必須使軸承處的潤(rùn)滑能保持清潔，并注意添?yè)Q。 </p> <p> 2、螺桿泵經(jīng)常檢查維修，電動(dòng)油桶泵應(yīng)經(jīng)常檢查，維修，須檢查電源線：內(nèi)接線，插頭，開關(guān)是否良好，絕緣電阻是否正常，刷尾座是事松動(dòng)，換向器與電刷接觸良好，電樞繞級(jí)擴(kuò)定子繞組是否是有適中斷路現(xiàn)象，軸承及轉(zhuǎn)動(dòng)零件是否的損壞等等。 </p> <p> 3、注意保存電動(dòng)抽油泵應(yīng)放于干燥，清潔和沒(méi)有腐蝕性氣體的環(huán)境中。 </p> <p> 4、保存好每零件和調(diào)換相同零件，在拆檢螺桿泵時(shí)，應(yīng)保存好每個(gè)零件，要特別注意隔爆零件的隔爆面不能使其損傷拉毛包括絕緣襯墊及套管，如有損壞，必須調(diào)換上新的相同零件，不得采用低于原材料性能的代用材料或原有規(guī)格不符的零件，裝配時(shí)應(yīng)將所有零件按原先位置裝好，不能遺漏。 </p> <p> 5、螺桿泵注意絕緣電阻，長(zhǎng)期擱置不用的或在潮濕環(huán)境中使用的電動(dòng)抽液泵，使用前必須用500伏兆歐表測(cè)量繞組的絕緣電阻。如繞組與電機(jī)殼間絕緣電阻小于7兆歐時(shí)，必須對(duì)繞組進(jìn)行干燥處理。 </p> <p> <br /> </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，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，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 /> 單螺桿泵流量與泵的轉(zhuǎn)速成正比，因而具有良好的變量調(diào)節(jié)性.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="肇慶螺桿泵制造廠家,螺桿泵"

***腐蝕也稱為均勻腐蝕，它的特點(diǎn)是腐蝕均勻地發(fā)生在整個(gè)金屬的表面，腐蝕的結(jié)果是設(shè)備壁厚的均勻減薄。***腐蝕容易被發(fā)現(xiàn)和測(cè)量，因此這種臠蝕的危險(xiǎn)性較小，只要在螺桿泵的設(shè)計(jì)時(shí)考慮足夠的腐蝕裕量就可以保證螺桿泵的機(jī)械強(qiáng)度和*吏用壽命。 </p> <p> <br /> </p> <p> 局部腐蝕又稱為非均勻腐蝕，它的特點(diǎn)是腐蝕集中在金屬表面的一定區(qū)域，而其他區(qū)域不腐蝕或腐蝕很輕微。這類腐蝕又包括區(qū)域腐蝕、點(diǎn)腐蝕、晶間腐蝕、應(yīng)力腐蝕、腐蝕疲勞和空泡腐蝕等。 </p> <p> <br /> </p> <p> <br /> 單螺桿泵正是基于這種結(jié)構(gòu)研發(fā)的新型泵種。汕頭本地螺桿泵</p><p style="text-indent:25px">螺桿泵可以用于高粘度流體的輸送和含有硬質(zhì)懸浮顆粒介質(zhì)或含有纖維介質(zhì)的輸送。肇慶螺桿泵制造廠家</p><p> 污泥螺桿泵因其有可變量輸送、自吸能力強(qiáng)、可逆轉(zhuǎn)、能輸送含固體顆粒的液體等特點(diǎn)，在污水處理廠中，***地被使用在輸送水、濕污泥和絮凝劑藥液方面。螺桿泵選用應(yīng)遵循經(jīng)濟(jì)、合理的原則。如果在設(shè)計(jì)選型方面考慮不周，會(huì)給以后的使用、管理、維修帶來(lái)麻煩，所以選用一臺(tái)按生產(chǎn)實(shí)際需要，合理可靠的污泥螺桿泵既能保證生產(chǎn)順利進(jìn)行，又可降低修理成本。 </p> <p> 一、污泥螺桿泵的轉(zhuǎn)速選用 </p> <p> 螺桿泵的流量與轉(zhuǎn)速成線性關(guān)系，相對(duì)于低轉(zhuǎn)速的污泥螺桿泵，高轉(zhuǎn)速的污泥螺桿泵雖能增加了流量和揚(yáng)程，但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使污泥螺桿泵過(guò)早失效，而且高轉(zhuǎn)速污泥螺桿泵的定轉(zhuǎn)子長(zhǎng)度很短，極易磨損，因而縮短了螺桿泵的使用壽命。
