3、使用中隨時(shí)注意泵的流量、壓力等狀況，如發(fā)現(xiàn)流量、壓力突然變化或有異聲，應(yīng)及時(shí)檢查解決。 </p> <p> 4、對(duì)于高粘度、有結(jié)晶、含顆?；蛴懈g性介質(zhì)的泵，使用完畢后，應(yīng)進(jìn)行清洗，防止沉積或損壞。 </p> <p> 安裝 </p> <p> <br /> </p> <p> <br /> </p> <p> 1、注意污泥螺桿泵的傳動(dòng)系統(tǒng)的同軸度，出廠前，泵及動(dòng)力端(有的包括底座)已作調(diào)整。但在安裝時(shí)，由于基礎(chǔ)不平，擰緊地腳螺栓，可能造成底座扭曲，造成聯(lián)軸器中心偏移。應(yīng)重新檢查聯(lián)軸器安裝偏差。 </p> <p> <br /> </p> <p> 2、出液口前應(yīng)安裝一段長(zhǎng)度略大于定子的易拆卸管線，以利于更換定子。 </p> <p> <br /> </p> <p> 3、泵的進(jìn)口在垂直方向，出口在水平方向，這樣可使密封在負(fù)壓狀態(tài)工作，減小密封腔的壓力，旋向：從出口方向看逆時(shí)針旋轉(zhuǎn)。另外泵的進(jìn)出口法蘭(管道)不應(yīng)承受管道重量，所以管道應(yīng)設(shè)支撐點(diǎn)。 </p> <p> <br /> </p> <p> 4、管道在安裝前必須清洗干凈，防止異物損壞定子、轉(zhuǎn)子，并造成堵塞。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 潮州螺桿泵收購(gòu)價(jià)G型單螺桿泵故障與排除。</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(rùn)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> 點(diǎn)腐蝕是由局部電作用引起的，腐蝕從金屬表面開(kāi)始，***產(chǎn)生凹坑，凹坑可能會(huì)被腐蝕產(chǎn)物覆蓋，結(jié)成瘤狀形的硬疤，疤的下面就是一個(gè)點(diǎn)蝕坑。點(diǎn)蝕經(jīng)常發(fā)生在金屬表面上有停滯或緩慢流動(dòng)介質(zhì)的區(qū)域。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 晶間腐蝕先從金屬表面晶粒之間的邊緣開(kāi)始，腐蝕介質(zhì)逐步滲人到金屬的深處，破壞了金屬晶粒之間的結(jié)合力，在金屬表面不會(huì)留下宏觀的跡象，從表面不易發(fā)現(xiàn)，但金屬材料的強(qiáng)度和塑性幾乎完全喪失，只要在很小的外力作用下就可能破壞。比如，不銹鋼經(jīng)過(guò)嚴(yán)重晶間腐蝕后，表面看起來(lái)仍十分光滑，但只要用錘輕輕敲擊，它就會(huì)碎成粉末。由于設(shè)備在工作過(guò)程中晶間腐蝕不容易被發(fā)現(xiàn)，所以它是一種危險(xiǎn)性比較大的腐蝕破壞形式。

螺桿泵的種類較多，相對(duì)而言，進(jìn)口的螺桿泵設(shè)計(jì)合理，材質(zhì)精良，但價(jià)格較高，服務(wù)方面有的不到位，配件價(jià)格高，訂貨周期長(zhǎng)，可能影響生產(chǎn)的正常運(yùn)行。 </p> <p> 國(guó)內(nèi)生產(chǎn)的大都仿制進(jìn)口產(chǎn)品，產(chǎn)品質(zhì)量良莠不齊，在選用國(guó)內(nèi)生產(chǎn)的產(chǎn)品時(shí)，在考慮其性價(jià)比的時(shí)候，選用低轉(zhuǎn)速，長(zhǎng)導(dǎo)程，傳動(dòng)量部件材質(zhì)優(yōu)良，額定壽命長(zhǎng)的產(chǎn)品。 </p> <p> 三、確保雜物不進(jìn)入泵體 </p> <p> 濕污泥中混入的固體雜物會(huì)對(duì)螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進(jìn)入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機(jī)，也有的安裝格柵裝置或?yàn)V網(wǎng)，阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。 </p> <p> <br /> </p> <p> <br /> </p> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 更換填料時(shí)，應(yīng)全部更換，軸若磨損嚴(yán)重也應(yīng)更換。汕尾螺桿泵批發(fā)廠家</p><p

產(chǎn)生原因：泵體和吸水管沒(méi)灌滿引水；動(dòng)水位低于水泵濾水管；吸水管破裂等。螺桿泵因其有可變量輸送、自吸能力強(qiáng)、可逆轉(zhuǎn)、能輸送含固體顆粒的液體等特點(diǎn)，在污水處理廠中，***地被使用在輸送水、濕污泥和絮凝劑藥液方面。螺桿泵選用應(yīng)遵循經(jīng)濟(jì)、合理、可靠的原則。如果在設(shè)計(jì)選型方面考慮不周，會(huì)給以后的使用、管理、維修帶來(lái)麻煩，所以選用一臺(tái)按生產(chǎn)實(shí)際需要，合理可靠的螺桿泵既能保證生產(chǎn)順利進(jìn)行，又可降低修理成本。
