</p> <p> <br /> </p> <p> A：二氟氫化鉀屬0性液體，所以選用隔膜式泵給客戶；泵體材質選用襯氟材質，膜片用F46材質，由于F46膜片里層還有加裝一付丁腈膜片，介質溫度再80-100℃，所以還要將里層的丁腈膜片換成三元乙丙橡膠膜片 </p> <p> <br /> </p> <p> Q：DP型微型螺桿泵說明書上寫吸程五米指的垂直自吸高度嗎？ A：經(jīng)車間測試，潮州螺桿泵價格網(wǎng)，DP型微型螺桿泵系列的自吸高度在5M左右 </p> <p> <br /> </p> <p> Q：液壓隔膜計量泵是雙隔膜的嗎？ </p> <p> <br /> </p> <p> A：液壓隔膜式計量泵有單膜片的也有帶雙隔膜報警的，雙膜片的好處就是，當***張膜片破損的情況下，不會馬上泄露，第二張膜片起到密封作用，通知泵上會有聲光報警，提醒現(xiàn)場及時停機檢測，潮州螺桿泵價格網(wǎng)，更換膜片。 </p> <p> <br /> 壓力高而均勻，流量均勻，潮州螺桿泵價格網(wǎng)，轉速高，能與原動機直聯(lián)。潮州螺桿泵價格網(wǎng)</p><div

單螺桿泵是一種單螺桿式輸運泵，它的主要工作部件是偏心螺旋體的螺桿（稱轉子）和內(nèi)表面呈雙線螺旋面的螺桿襯套（稱定子）。單螺桿泵工作原理是當電動機帶動泵軸轉動時，螺桿一方面則繞本身的軸線旋轉，另一方面它又沿襯套內(nèi)表面滾動，這樣便會形成泵的密封腔室。螺桿每轉一周，密封腔內(nèi)的液體向前推進一個螺距，隨著螺桿的連續(xù)轉動，液體螺旋形方式從一個密封腔壓向另一個密封腔，***擠出泵體。單螺桿泵常適用于石蠟、糖蜜、果肉、巧克力漿、油漆、柏油、淀粉糊、潤滑脂、泥漿、黏土、陶土等介質的傳送。雙螺桿泵是外嚙合的螺桿泵，它利用相互嚙合，互不接觸的兩根螺桿來抽送液體。雙螺桿泵的一端伸出泵外的主動螺桿由原動機驅動，主動螺桿與從動螺桿具有不同旋向的螺紋，螺桿與泵體緊密貼合，從動螺桿是通過同步齒輪由主動螺桿帶動的。泵內(nèi)吸入室應與排出室嚴密地隔開，因此，泵體與螺桿外圓表面及螺桿與螺桿間隙應盡可能小些，同時螺桿與泵體、螺桿與螺桿間又相互形成密封腔，保證密閉，否則就可能有液體從間隙中倒流回去。 </p> <p> 雙螺桿泵常適用于潤滑油、潤滑脂、原油、柏油、燃料油及其他高黏度油等介質的傳送。 </p> <p> <br /> </p> <p> <br /> 廣州螺桿泵高質量的選擇根據(jù)泵的大小不同可以輸送粘度從厘泊的介質。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="潮州螺桿泵價格網(wǎng),螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906914062/9768480.jpg"></div><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，有的介質呈酸性，有的介質呈堿性?有的介質腐蝕性強，有的介質腐蝕性弱等。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中的腐蝕情況各不相同，同一種材料在不同介質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。</p><p> 2、單螺桿泵的運行 </p> <p> 螺桿泵必須按規(guī)定的方向工作，以產(chǎn)生一定的吸力和流量。在工作時，應檢查壓力、溫度和機械密封。對于軸封，應有輕微泄漏。如果泄漏量不超過20-30秒/滴，則認為是正常的。如果螺桿泵在工作中產(chǎn)生噪聲，則經(jīng)常是由于油溫度低、油粘度高、油中空氣、耦合損失和泵的過度磨損造成的。 </p> <p> <br /> </p> <p> 3、單螺桿泵停車 </p> <p> 螺桿泵停止后，首先關閉排氣停止閥，關閉泵后關閉吸入截止閥。由于螺桿長度大，剛性差，螺桿泵容易產(chǎn)生彎曲，造成異常工作，軸系統(tǒng)的連接必須良好，中間工作比較好是在安裝和定位后進行，避免管路連接。應引起變形，連接管應**固定，盡可能減少泵的連接等，另外，備用螺絲比較好在存放期間懸掛和固定，以避免因放置不均勻引起的變形。 </p> <p> <br /> </p> <p> <br /> 污泥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><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="潮州螺桿泵價格網(wǎng),螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876905205078/500946.jpg"></div><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> <br

螺桿泵，螺旋泵，亦稱“螺旋揚水機”、“阿基米德螺旋泵”。利用螺旋葉片的旋轉，使水體沿軸向螺旋形上升的一種泵。由軸、螺旋葉片、外殼組成。抽水時，將泵斜置水中，使水泵主軸的傾角小于螺旋葉片的傾角，螺旋葉片的下端與水接觸。當原動機通過變速裝置帶動螺旋泵軸旋轉時，水就進入葉片，沿螺旋型流道上升，直至出流。結構簡單，制造容易，流量較大，水頭損失小，效率較高，便于維修和保養(yǎng)，但揚程低，轉速低，需設變速裝置。多用于灌溉、排澇，以及提升污水、污泥等場合。中國從20世紀70年代開始使用。螺旋泵的裝置包括原動機、變速傳動裝置和螺旋泵三部分，如圖1所示，具體是由螺旋葉片1、泵軸2、軸承座
