2）由于轉(zhuǎn)子每轉(zhuǎn)一周，密封腔數(shù)為2×3 =6,而單頭螺旋轉(zhuǎn)子和雙頭內(nèi)螺旋定子的泵，密封腔數(shù)為1×2 =2,因此其流量脈動(dòng)和壓力脈動(dòng)較小。 </p> <p> 3 ）轉(zhuǎn)子的偏心距較小，因此噪聲和振動(dòng)也隨之降低，并允許采用較高的轉(zhuǎn) 速，或在相同的轉(zhuǎn)速和相同流量時(shí)，吸上性能更好。 </p> <p> 4）容積效率和機(jī)械效率也更高。 </p> <p> 5)起動(dòng)力距較小。 </p> <p> 6)壽命更長(zhǎng)。 </p> <p> <br /> </p><p> 3、螺桿泵的螺桿在機(jī)筒內(nèi)轉(zhuǎn)動(dòng)，物料與二者的摩擦，使螺桿與機(jī)筒的工作表面逐漸磨損：螺桿直徑逐漸縮小，機(jī)筒的內(nèi)孔直徑逐漸加大。這樣，螺桿與機(jī)筒的配合直徑間隙，隨著二者的逐漸磨損而一點(diǎn)點(diǎn)加大?？墒牵捎跈C(jī)筒前面機(jī)頭和分流板的阻力沒(méi)有改變，這就增加了被擠塑物料前進(jìn)時(shí)的漏流量，即物料從直徑間隙處向進(jìn)料方向流動(dòng)量增加。結(jié)果使塑膠機(jī)械生產(chǎn)量下降。這種現(xiàn)象又使物料在機(jī)筒內(nèi)停留時(shí)間增加，造成物料分解。如果是聚乙烯，分解產(chǎn)生的氯化氫氣體加強(qiáng)了對(duì)螺桿和機(jī)筒的腐蝕。 </p> <p> <br /> </p> <p> 4、物料中如有碳酸鈣和玻璃纖維等填充料，能加快螺桿和機(jī)筒的磨損。 </p> <p> <br /> </p> <p> 5、由于物料沒(méi)有塑化均勻，或是有金屬異物混入料中，使螺桿轉(zhuǎn)動(dòng)扭矩力突然增加，這種扭矩超出螺桿的強(qiáng)度極限，使螺桿扭斷。這是一種非常規(guī)***損壞。 </p> <p> <br /> 診斷的方法是確定抽油系統(tǒng)的總效率,而確定總效率只需測(cè)量輸入原動(dòng)機(jī)的功率。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="***螺桿泵推薦企業(yè),螺桿泵"

輸入污水時(shí)如何合理使用螺桿泵，螺桿泵現(xiàn)如今***的應(yīng)用在污水處理行業(yè)，因?yàn)槠淠軌蜃晕芰?qiáng)、可變量輸送、可逆轉(zhuǎn)、能輸送高粘度、含固體顆粒的液體等突出優(yōu)點(diǎn)，***地被使用在輸送水、濕污泥和絮凝劑藥液方面。 </p> <p> 螺桿泵選用時(shí)如果考慮不周，將會(huì)給以后的使用、管理、維修帶來(lái)巨大的麻煩，因此客戶在選擇螺桿泵時(shí)必須選用一臺(tái)按生產(chǎn)實(shí)際需要，合理可靠的螺桿泵，這樣既能保證生產(chǎn)順利進(jìn)行，又可降低修理成本。同時(shí)在輸送污水時(shí)還要注意合理使用我妮螺桿泵，現(xiàn)將我們?cè)趹?yīng)用螺桿泵的一些體會(huì)介紹如下：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)單螺桿泵的橡膠材質(zhì)定子造成損壞，所以必須確保雜物不進(jìn)入單螺桿泵泵的腔體，建議可以在泵前加裝粉碎機(jī)，或者安裝格柵裝置或?yàn)V網(wǎng)以便阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。計(jì)量泵保持恒定的出口壓力 </p> <p> 單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，甚至將會(huì)超過(guò)預(yù)定的壓力值，增加電機(jī)負(fù)荷，同時(shí)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)。離心泵

3、診斷低能效井。診斷的方法是確定抽油系統(tǒng)的總效率,而確定總效率只需測(cè)量輸入原動(dòng)機(jī)的功率、測(cè)定井底生產(chǎn)壓力和精確的生產(chǎn)測(cè)試數(shù)據(jù)。一般抽油系統(tǒng)的總效率應(yīng)為50％左右,若低于此應(yīng)提高其性能。提高總效率的技術(shù)包括保持高容積效率(泵的規(guī)格與井筒注入量匹配、消除氣干擾、用抽空控制器或定時(shí)器控制抽油)和換掉過(guò)大的電動(dòng)機(jī)。 </p> <p> <br /> </p> <p> 4、井下氣分離。無(wú)效的泵運(yùn)轉(zhuǎn)常是氣干擾造成的，可通過(guò)聲波液面測(cè)量和示功圖進(jìn)行診斷。比較好是將泵吸入口置于流體進(jìn)入層段的下方，若置于上方則應(yīng)使用氣體分離器。若閥座短節(jié)布置于流體進(jìn)入層段底部以下至少10ft，則在環(huán)空中可發(fā)生有效氣分離，此時(shí)套管起分離器外筒的作用。但井的條件常不容許將泵置于流體進(jìn)入層下方，則考慮用井下氣分離器。常規(guī)的氣分離器由流體進(jìn)入部分(如射孔短節(jié))、外筒(如底部有堵頭的一節(jié)油管)和泵底部的封液管組成。
