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。要求輸送壓力穩(wěn)定，介質(zhì)固有結(jié)構(gòu)不受破壞時(shí)，選用單螺桿泵輸送**為理想。</p><div

它主要是由固定在泵體中的襯套（泵缸）以及安插在泵缸中的主動(dòng)螺桿和與其嚙合的兩根從動(dòng)螺桿所組成。三根互相嚙合的螺桿，在泵缸內(nèi)按每個(gè)導(dǎo)程形成為一個(gè)密封腔，造成吸排口之間的密封。 </p> <p> 泵工作時(shí)，由于兩從動(dòng)螺桿與主動(dòng)螺桿左右對(duì)稱嚙合，故作用在主動(dòng)螺桿上的徑向力完全平衡，主動(dòng)螺桿不承受彎曲負(fù)荷。從動(dòng)螺桿所受徑向力沿其整個(gè)長(zhǎng)度都由泵缸襯套來支承，因此，不需要在外端另設(shè) 軸承，基本上也不承受彎曲負(fù)荷。在運(yùn)行中，螺桿外圓表面和泵缸內(nèi)壁之間形成的一層油膜，可防止金屬之間的直接接觸，使螺桿齒面的磨損**減少。 </p> <p> 螺桿泵工作時(shí)，兩端分別作用著液體的吸排壓力，因此對(duì)螺桿要產(chǎn)生軸向推力。對(duì)于壓差小于10千克力/cm2 的小型泵，可以采用止推軸承。此外，還通過主動(dòng)螺桿的**油孔將高壓油引入各螺桿軸套的底部，從而在螺桿下端產(chǎn)生一個(gè)與軸向推力方向相反的平衡推力。 </p> <p> 螺桿泵和其它容積泵一樣，當(dāng)泵的排出口完全封閉時(shí)，泵內(nèi)的壓力就會(huì)上升到使泵損壞或使電動(dòng)機(jī)過載的危險(xiǎn)程度。所以，在泵的吸排口處，就必須設(shè)置安全閥。 </p> <p> 螺桿泵的軸封，通常采用機(jī)械軸封，并可根據(jù)工作壓力的高低采取不同的形式。 </p> <p> <br />

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，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 /> 清遠(yuǎn)螺桿泵批發(fā)廠家</p><p
