class="title">詳細(xì)說明</p><div id="ic2ya78" class="box"><p><p> G型單螺桿泵螺桿軸磨損五點(diǎn)原因： </p> <p> 1、每種塑料，都有一個(gè)理想塑化的加工溫度范圍，應(yīng)該控制料筒加工溫度，使之接近這個(gè)溫度范圍。粒狀塑料從料斗進(jìn)入料筒，首先會(huì)到達(dá)加料段，清遠(yuǎn)螺桿泵誠(chéng)邀品鑒，在加料段必然會(huì)出現(xiàn)干性磨擦，當(dāng)這些塑料受熱不足，熔融不均時(shí)，很易造成料筒內(nèi)壁及螺桿表面磨損增大，清遠(yuǎn)螺桿泵誠(chéng)邀品鑒。同樣，清遠(yuǎn)螺桿泵誠(chéng)邀品鑒，在壓縮段和均化段，如果塑料的熔融狀態(tài)紊亂不均，也會(huì)造成磨損增快。 </p> <p> 2、轉(zhuǎn)速應(yīng)調(diào)校得當(dāng)。由于部分塑料加有強(qiáng)化劑，如玻璃纖維、礦物質(zhì)或其他填充料。這些物質(zhì)對(duì)金屬材質(zhì)的磨擦力往往比熔融塑料的大得多。在注塑這些塑料時(shí)，如果用高的轉(zhuǎn)速成，則在提高對(duì)塑料的剪切力的同時(shí)，亦將令強(qiáng)化相應(yīng)地產(chǎn)生更多被撕碎的纖維，被撕碎的纖維含有鋒利末端，令磨損力大為增加。無機(jī)礦物質(zhì)在金屬表面高速滑行時(shí)，其刮削作用也不小。所以轉(zhuǎn)速不宜調(diào)得太高。 </p> <p> <br /> 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。清遠(yuǎn)螺桿泵誠(chéng)邀品鑒</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="清遠(yuǎn)螺桿泵誠(chéng)邀品鑒,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876901093750/5238493.jpg"></div><p> 點(diǎn)腐蝕是由局部電作用引起的，腐蝕從金屬表面開始，***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)過嚴(yán)重晶間腐蝕后，表面看起來仍十分光滑，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。

alt="清遠(yuǎn)螺桿泵誠(chéng)邀品鑒,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906972656/3705264.jpg"></div><p 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 style="text-indent:25px">常見螺桿泵的特點(diǎn)和應(yīng)用，螺桿泵依靠螺桿相互嚙合（或螺桿與定子嚙合）空間的容積變化來輸送液體。當(dāng)螺桿轉(zhuǎn)動(dòng)時(shí)吸入腔一端作軸向移動(dòng)，使吸入腔的容積增大，壓力降低，液體在壓差作用下沿吸入管進(jìn)入吸入腔。隨著螺桿的轉(zhuǎn)動(dòng)，密封腔內(nèi)的液體連續(xù)而均勻地沿軸向移動(dòng)到排出腔，由于排出腔一端的容積逐漸縮小，即將液體排出。螺桿泵的特點(diǎn)是流量和壓力脈動(dòng)小、運(yùn)轉(zhuǎn)平穩(wěn)、噪聲低、效率高、壽命長(zhǎng)、有較強(qiáng)的自吸能力而且結(jié)構(gòu)簡(jiǎn)單緊湊；其突出的優(yōu)點(diǎn)是輸送介質(zhì)時(shí)不形成渦流、對(duì)介質(zhì)的粘性不敏感，可輸送高粘度介質(zhì)。螺桿泵按螺桿數(shù)目分為單螺桿泵、雙、三和五螺桿泵。單螺桿泵的結(jié)構(gòu)為單頭陽螺旋轉(zhuǎn)子在特殊的雙頭陰螺旋定子內(nèi)偏心地轉(zhuǎn)動(dòng)（定子是柔性的），能沿泵中心線來回?cái)[動(dòng)，與定子始終保持嚙合；雙螺桿泵結(jié)構(gòu)為有兩根同樣大小的螺桿軸，一根為主動(dòng)軸，一根為從動(dòng)軸，通過齒輪傳動(dòng)達(dá)到同步旋轉(zhuǎn)；三螺桿泵結(jié)構(gòu)為有一根主動(dòng)螺桿和兩根與之相嚙合的從動(dòng)螺桿所構(gòu)成；五螺桿泵的結(jié)構(gòu)為定子內(nèi)裝有五根左、右旋的螺桿軸，螺桿的共軛齒廓上有一段漸開線，它起主動(dòng)螺桿泵向從動(dòng)螺桿傳遞運(yùn)動(dòng)的作用。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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="清遠(yuǎn)螺桿泵誠(chéng)邀品鑒,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906445312/5967838.jpg"></div><p> 與葉片泵相比較，螺旋泵具有以下優(yōu)點(diǎn)： </p> <p> ①轉(zhuǎn)速低(一般為20r/min～90r/min)，機(jī)械磨損小，不會(huì)發(fā)生汽蝕。 </p> <p> ②流道寬，可以輸送含有固體物的水。 </p> <p> ③泵體結(jié)構(gòu)是半開的，可以觀察到泵內(nèi)的運(yùn)行情況。 </p> <p> ④吸入側(cè)流態(tài)對(duì)水力性能影響甚微，對(duì)吸水池?zé)o特殊要求，基礎(chǔ)開挖深度小，水工建筑物施工簡(jiǎn)單，土建費(fèi)用少。 </p> <p> 其缺點(diǎn)是： </p> <p> ①尺寸大，占地面積也大。 </p> <p> ②受機(jī)械加工條件限制，泵軸不能太長(zhǎng)，因而揚(yáng)程較低，一般不超過10m。 </p> <p> ③吸水面、出水面高度變化不能太大，否則會(huì)影響工作效率，增加能耗。 </p> <p> <br /> 單螺桿泵、污泥螺桿泵、濃漿泵是一種正排量泵。清遠(yuǎn)螺桿泵誠(chéng)邀品鑒</p><p style="text-indent:25px">采用***無味的食用橡膠，工作溫度可達(dá)120攝氏度。清遠(yuǎn)螺桿泵誠(chéng)邀品鑒</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> 四、避免斷料 </p> <p> 污泥螺桿泵決不允許在斷料的情形下運(yùn)轉(zhuǎn)，一經(jīng)發(fā)生，橡膠定子由于干磨擦，瞬間產(chǎn)生高溫而燒壞，所以，粉碎機(jī)完好，格柵暢通是污泥螺桿泵正常運(yùn)轉(zhuǎn)的必要條件之一，為此，有些螺桿泵還在泵身上安裝了斷料停機(jī)裝置，當(dāng)發(fā)生斷料時(shí)，由于螺桿泵其有自吸功能的特性，腔體內(nèi)會(huì)產(chǎn)生真空，真空裝置會(huì)使螺桿泵停止運(yùn)轉(zhuǎn)。 </p> <p> 五、保持恒定的出口壓力 </p> <p> 污泥螺桿泵是一種容積式回轉(zhuǎn)泵，當(dāng)出口端受阻以后，壓力會(huì)逐漸升高，以至于超過預(yù)定的壓力值。此時(shí)電機(jī)負(fù)荷急劇增加。傳動(dòng)機(jī)械相關(guān)零件的負(fù)載也會(huì)超出設(shè)計(jì)值，嚴(yán)重時(shí)會(huì)發(fā)生電機(jī)燒毀、傳動(dòng)零件斷裂。為了避免螺桿泵損壞，一般會(huì)在螺桿泵出口處安裝旁通溢流閥，用以穩(wěn)定出口壓力，保持泵的正常運(yùn)轉(zhuǎn)。
