(2)間隙。間隙指螺旋葉片與外殼之間的間隙。間隙越小，水漏損失就越小，泵的效率就越高。 </p> <p> (3)轉(zhuǎn)速(n)。螺旋泵的轉(zhuǎn)速較慢，一般為20～80 r/min。實驗資料證明：螺旋泵的外徑較大時，轉(zhuǎn)速宜減小。 </p> <p> (4)提升高度(H)。螺旋泵只有提升高度，而沒有壓水高度。它的提升高度一般為3～8 m。 </p> <p> (5)螺旋葉片直徑(D)。泵的葉片直徑越大，其效率越高，螺旋泵的葉片直徑與泵軸直徑的比較好比例為2:1。 </p> <p> (6)頭數(shù)(Z)。頭數(shù)指螺旋葉片的片數(shù)，一般為1～4片。它們相隔一定的間距環(huán)繞泵軸螺旋上升。頭數(shù)越多，泵效率也越高。對于一定直徑的螺旋泵，每增加一個葉片頭數(shù)，提升能力約增加20%，揭陽螺桿泵批發(fā)廠家。

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(zhuǎn)，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(zhuǎn)時，水就進入葉片，沿螺旋型流道上升，直至出流。結(jié)構(gòu)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(zhuǎn)速低，需設(shè)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

style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揭陽螺桿泵批發(fā)廠家,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876901611328/4013793.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，就會被分隔成一個或多個密封空間。隨著螺桿的轉(zhuǎn)動和嚙合，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)時被不斷向前推進的情形那樣，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，液體被吸入后就進入螺紋與泵殼所圍的密封空間，當主動螺桿旋轉(zhuǎn)時，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。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。污泥螺桿泵特點為：螺桿泵損失小，經(jīng)濟性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動機直聯(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。單螺桿泵體積小，重量輕、噪聲低，結(jié)構(gòu)簡單，維修方便.揭陽螺桿泵批發(fā)廠家</p><p style="text-indent:25px">使泵排量與流入井底的液量相匹配，就可以提高效率和降低成本。揭陽螺桿泵批發(fā)廠家</p><p> 三、確保雜物不進入泵體 </p> <p> 濕污泥中混入的固體雜物會對螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機，也有的安裝格柵裝置或濾網(wǎng)，阻擋雜物進入螺桿泵，對于格柵應(yīng)及時清撈以免造成堵塞。 </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，粉碎機完好，格柵暢通是污泥螺桿泵正常運轉(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裝置，當發(fā)生斷料時，由于螺桿泵其有自吸功能的特性，腔體內(nèi)會產(chǎn)生真空，真空裝置會使螺桿泵停止運轉(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，當出口端受阻以后，壓力會逐漸升高，以至于超過預(yù)定的壓力值。此時電機負荷急劇增加。傳動機械相關(guān)零件的負載也會超出設(shè)計值，嚴重時會發(fā)生電機燒毀、傳動零件斷裂。為了避免螺桿泵損壞，一般會在螺桿泵出口處安裝旁通溢流閥，用以穩(wěn)定出口壓力，保持泵的正常運轉(zhuǎn)。 </p> <p> <br />
