單螺桿泵的嚙合副型線，近十多年來國外有些廠商開發(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展很快，個別的廠商已發(fā)展到大批量生產(chǎn)和銷售。我國也有少數(shù)制造廠進行研制，目前尚處在開發(fā)階段。 </p> <p> 雙頭螺旋轉(zhuǎn)子和三頭內(nèi)螺旋定子構成的單螺桿泵與單頭螺旋轉(zhuǎn)子和雙頭內(nèi)螺旋定子構成的單螺桿泵相比較，有著如下的優(yōu)點： </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，或在相同激量時導程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,因此其流量脈動和壓力脈動較小。 </p> <p> 3 ）轉(zhuǎn)子的偏心距較小，因此噪聲和振動也隨之降低，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，吸上性能更好。 </p> <p> 4）容積效率和機械效率也更高。 </p> <p> 5)起動力距較小。 </p> <p> 6)壽命更長。 </p> <p> <br /> </p><p> 螺桿泵是否要配置安全閥？好處有哪些，選購螺桿泵的時候經(jīng)常困擾是否要給螺桿泵廢紙安全閥？到底有沒有必要？配置安全閥之后又有哪些好處呢？螺桿泵的一個重要特點是在泵的強度允許的情況下，其排出壓力取決于它的背壓。因此，當螺桿泵運行時，一旦排出管路堵塞或操作失誤未打開排出閥門等原因，排出壓力就會急劇升高，導致泵過載損壞。 </p> <p> 螺桿泵配置了安全閥就能使當排出壓力超過某規(guī)定值時，安全閥在排出壓力作用下，開啟安全閥內(nèi)的閥，介質(zhì)就回流至泵的進口端，從而使排出壓力回落，避免了排出壓力的進一步升高，保護螺桿泵不被破壞。泵配置安全閥的原因:長期以來螺桿泵為了防止泵過載引起的破壞，通常采用在泵上配置安全閥或在泵的出口管路上配囂安全閥的措施。以上就是答案，希望能夠幫助到被此問題困擾的客戶。 </p> <p>

單雙螺桿泵和普通的工作原理及產(chǎn)品介紹，螺桿泵是利用螺桿的回轉(zhuǎn)來吸排液體的。螺桿為主動螺桿，由原動機帶動回轉(zhuǎn)，兩邊的螺桿為從動螺桿，隨主動螺桿作反向旋轉(zhuǎn)。主、從動螺桿的螺紋均為雙頭螺紋。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，就會被分隔成一個或多個密封空間。隨著螺桿的轉(zhuǎn)動和嚙合，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)時被不斷向前推進的情形那樣，這就是螺桿泵的基本工作原理。 </p> <p> <br /> </p> <p> 螺桿泵有單螺桿泵、雙螺桿泵和三螺桿泵。 </p> <p> <br /> </p> <p> 螺桿泵的工作原理是：螺桿泵工作時，液體被吸入后就進入螺紋與泵殼所圍的密封空間，當主動螺桿旋轉(zhuǎn)時，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。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。 </p> <p> <br /> </p> <p> 螺桿泵特點為：螺桿泵損失小，經(jīng)濟性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動機直聯(lián)。 </p> <p> <br /> </p> <p> 螺桿泵可以輸送潤滑油，輸送燃油，輸送各種油類及高分子聚合物，用于輸送黏稠液體。 </p> <p> <br /> G型單螺桿泵故障與排除。茂名螺桿泵誠信互利</p><p

style="text-indent:25px">螺桿泵的腐蝕與防護，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幾百度，壓力可達幾十兆帕，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，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金屬材料的腐蝕情況，從而針對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，并且采取相應的防腐措施以延長螺桿泵的使用壽命，這也是石油化工用螺桿泵的一個非常重要的問題。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)品等化學介質(zhì)的腐蝕，但是對***、鹽酸、氫氟酸、鹵素、草酸等的化學穩(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。梅州螺桿泵經(jīng)銷批發(fā)</p><p
