螺桿泵應(yīng)在吸入截止閥完全打開的情況下啟動，以防止過載或抽吸。螺桿泵雖然具有干燥和吸收的能力，但必須防止干旋，以免刮傷工作面。當(dāng)油溫較低或粘度很高時，泵需要啟動時，螺桿泵應(yīng)從吸入閥和旁通閥的完全開啟開始，使泵啟動時的負(fù)荷比較低，直到原動機(jī)達(dá)到額定轉(zhuǎn)速為止。旁通閥逐漸關(guān)閉。當(dāng)旁通閥打開時，液體在節(jié)流狀態(tài)下在泵內(nèi)循環(huán)，循環(huán)油越多，循環(huán)時間越長，液體的熱越嚴(yán)重，甚至由于高溫變形而損壞泵。必須注意。 </p> <p> <br /> </p> <p> 2、單螺桿泵的運(yùn)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(yīng)檢查壓力、溫度和機(jī)械密封。對于軸封，應(yīng)有輕微泄漏。如果泄漏量不超過20-30秒/滴，則認(rèn)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 /> 原裝螺桿泵一部分泵排量受氣干擾而損失，如果消除泵內(nèi)氣的干擾和控制泵的運(yùn)轉(zhuǎn)時間。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="東莞螺桿泵廠家電話地址,螺桿泵"

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)子因為使用的是鋼材所以比橡膠耐磨，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)。因為螺桿泵的工作環(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 /> </p><p> Q：DP型微型螺桿泵和MP型微型磁力驅(qū)動泵是否可以更換材質(zhì)輸送有機(jī)溶劑？（**、薏米） </p> <p> <br /> </p> <p> A：DP型微型螺桿泵/MP系列微型磁力泵，均不可以輸送有機(jī)溶劑類介質(zhì) </p> <p> <br /> </p> <p> Q：輸送二氟氫化鉀溫度低于80-100度液體會變成固體，螺桿泵是否可以輸送? </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(zhì)選用襯氟材質(zhì)，膜片用F46材質(zhì)，由于F46膜片里層還有加裝一付丁腈膜片，介質(zhì)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，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(dāng)***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(jī)檢測，更換膜片。 </p> <p> <br /> 重新裝泵前，應(yīng)做好各項更換、維修的準(zhǔn)備工作。</p><div style="width:100%;text-align:

不同金屬在電解質(zhì)溶液中的電位不同，它們之間會產(chǎn)生電位差；同一金屬由于本身**不均勻在電解質(zhì)溶液中也有可能產(chǎn)生電位差；同一金屬在電解質(zhì)溶液中所處的環(huán)境條件有差別（如濃度、溫度和應(yīng)力差別等）也會產(chǎn)生電位差。而在酸、堿、鹽等電解質(zhì) </p> <p> <br /> </p> <p> 溶液中都存在著帶正電荷的陽離子和帶負(fù)電荷的陰離子，電位差成了電解質(zhì)溶液中離子移動的推動力，離子移動到電極上得失電子的同時便會產(chǎn)生金屬的腐蝕，并同時產(chǎn)生電流。因此，電化學(xué)腐蝕是由于金屬發(fā)生腐蝕電池作用引起的。如果將兩種電位不同的金屬（如銅和鋅）用導(dǎo)線連接起來，放在電解質(zhì)溶液（如?。?SO4溶液）中,這樣就構(gòu)成了導(dǎo)電回路，回路中的電子將從低電位的鋅流向高電位的銅，電子的移動產(chǎn)生電流，形成腐蝕電池。鋅不斷失去電子，變?yōu)殇\離子進(jìn)人溶液，鋅電極成為腐蝕電池的極，出現(xiàn)腐蝕；銅電極成為腐蝕電池的陰極而被保護(hù)，溶液中的H＋不斷移動到銅電極上得到電子而析出H2。

單螺桿泵是一種單螺桿式輸運(yùn)泵，它的主要工作部件是偏心螺旋體的螺桿（稱轉(zhuǎn)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(dāng)電動機(jī)帶動泵軸轉(zhuǎn)動時，螺桿一方面則繞本身的軸線旋轉(zhuǎn)，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(zhuǎn)一周，密封腔內(nèi)的液體向前推進(jìn)一個螺距，隨著螺桿的連續(xù)轉(zhuǎn)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(zhì)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(jī)驅(qū)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(yīng)與排出室嚴(yán)密地隔開，因此，泵體與螺桿外圓表面及螺桿與螺桿間隙應(yīng)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(zhì)的傳送。 </p> <p> <br /> </p> <p> <br /> 東莞螺桿泵廠家電話地址</p><p
