</p> <p> <br /> </p> <p> 第二梯度是在我國進(jìn)行生產(chǎn)銷售的合資企業(yè)和外資企業(yè)產(chǎn)品。這類企業(yè)具有技術(shù)上的優(yōu)勢，且在國內(nèi)生產(chǎn)，物流周期短，生產(chǎn)成本也得以降低，因而市場價(jià)格相對進(jìn)口產(chǎn)品也有所下調(diào)。 </p> <p> <br />

應(yīng)力腐蝕是指拉應(yīng)力和腐蝕環(huán)境的聯(lián)合作用而引起的金屬腐蝕破裂，應(yīng)力和腐蝕是相互促進(jìn)的。一方面腐蝕使金屬有效截面積減小和表面形成缺口產(chǎn)生應(yīng)力集中，另一方面應(yīng)力的增大使材料產(chǎn)生大的變形又加速了腐蝕的進(jìn)展，使表面缺口向深處擴(kuò)展，往往在沒有任何預(yù)兆的情況下導(dǎo)致設(shè)備的破壞，因此應(yīng)力腐蝕破裂也是一種很危險(xiǎn)的腐蝕損壞。 </p> <p> <br /> </p> <p> 腐蝕疲勞又稱疲勞腐蝕，是指金屬材料或結(jié)構(gòu)在交變載荷和腐蝕介質(zhì)共同作用下引起的疲勞強(qiáng)度或疲勞壽命降低的現(xiàn)象。材料在長時(shí)間的交變載荷作用下，應(yīng)力值達(dá)到或超過材私的疲勞極限時(shí)就會(huì)使金屬表面產(chǎn)生微小裂紋，腐蝕介質(zhì)進(jìn)人微裂紋加速了裂紋向深處擴(kuò)展:***可能造成金屬構(gòu)件突然斷裂，從宏觀上看，斷口有兩個(gè)明顯不同的區(qū)域：一是腐蝕疲勞裂紋的產(chǎn)生和擴(kuò)展區(qū)，二是截面嶄新的***斷裂區(qū)。在石油化工生產(chǎn)行業(yè)的設(shè)備當(dāng)中，螺桿泵轱等均有可能發(fā)生腐蝕疲勞。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> 4、拆卸轉(zhuǎn)子、連桿、短節(jié)、密封盒先卸下三通。卸去鋼絲卡圈或緊定螺釘。退出圓柱銷防落套后，取下圓銷。接下來可分離轉(zhuǎn)子、連桿、短節(jié)、傳動(dòng)軸等零件。卸下短節(jié)后，即可取出密封盒。對采用機(jī)械密封的，則要非常小心翼翼地進(jìn)行，否則極易造成動(dòng)、靜環(huán)的破碎。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 5、重新裝泵前，應(yīng)做好各項(xiàng)更換、維修的準(zhǔn)備工作。嚴(yán)格檢查待裝零件的質(zhì)量，清洗是否干凈，外表是否損壞。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 6、裝配步驟正好與拆卸步驟相反。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 7、在裝配填料密封時(shí)，注意調(diào)整不要過緊。待試車進(jìn)料后逐步壓緊，以介質(zhì)略有滴漏為宜。如機(jī)械密封。則應(yīng)注意動(dòng)、靜環(huán)上無雜質(zhì)，并涂上潤滑脂。靜環(huán)必須平整地裝手密封盒。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 8、連桿節(jié)頭處應(yīng)檢查橡膠護(hù)套是否損壞。在空腔內(nèi)是否充滿潤滑脂。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 9、安裝定子時(shí)，橡膠表面涂以潤滑脂(包括轉(zhuǎn)子)，有利于安裝及試運(yùn)轉(zhuǎn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 污泥螺桿泵工作時(shí)，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間。</p><div

style="text-indent:25px">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(huì)被分隔成一個(gè)或多個(gè)密封空間。隨著螺桿的轉(zhuǎn)動(dòng)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(shí)被不斷向前推進(jìn)的情形那樣，這就是G型污泥螺桿泵的基本工作原理。污泥螺桿泵工作時(shí)，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間，當(dāng)主動(dòng)螺桿旋轉(zhuǎn)時(shí)，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(dòng)。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。污泥螺桿泵特點(diǎn)為：螺桿泵損失小，經(jīng)濟(jì)性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動(dòng)機(jī)直聯(lián)。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。測定井底生產(chǎn)壓力和精確的生產(chǎn)測試數(shù)據(jù)。汕頭螺桿泵來電咨詢</p><p style="text-indent:25px">拆卸轉(zhuǎn)子、連桿、短節(jié)、密封盒先卸下三通。河源高質(zhì)量螺桿泵</p><p> Q：DP型微型螺桿泵和MP型微型磁力驅(qū)動(dòng)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(huì)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(jì)量泵是雙隔膜的嗎？ </p> <p> <br /> </p> <p> A：液壓隔膜式計(jì)量泵有單膜片的也有帶雙隔膜報(bào)警的，雙膜片的好處就是，當(dāng)***張膜片破損的情況下，不會(huì)馬上泄露，第二張膜片起到密封作用，通知泵上會(huì)有聲光報(bào)警，提醒現(xiàn)場及時(shí)停機(jī)檢測，更換膜片。 </p> <p> <br /> 河源高質(zhì)量螺桿泵</p><p
