</p> <p> <br /> </p> <p> 現(xiàn)在市場(chǎng)上的螺桿泵的種類較多，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> <br />

螺桿泵型號(hào)的選型首先得確定螺桿泵所輸送的液體介質(zhì)具體是什么，里面所含有哪些化學(xué)成分以便確定選擇合適橡膠套滿足工況，列入家具行業(yè)輸送油漆，客戶只提供輸送油漆，得了解清楚油漆里面是否含有甲苯，如含有甲苯得選用氟橡膠材質(zhì)的橡膠套才能滿足工況，不然選擇普通的丁晴橡膠套很容易壞掉，用戶不了解的情況下誤認(rèn)為是廠家質(zhì)量的問(wèn)題所致，還有介質(zhì)的粘度及比重，如粘度大或者介質(zhì)含固量大的物料，要在普通轉(zhuǎn)速的基礎(chǔ)上降低螺桿泵的轉(zhuǎn)速，轉(zhuǎn)速低磨損就會(huì)降低，所以螺桿泵型號(hào)的選型及為重要。1級(jí)螺桿泵：比較高工作壓力為0.6 MPa； </p> <p> 2級(jí)螺桿泵：比較高工作壓力為1.2 MPa； </p> <p> 3級(jí)螺桿泵：比較高工作壓力為1.8Mpa； </p> <p> 4級(jí)螺桿泵：比較高工作壓力為2.4 MPa； </p> <p> 由于螺桿泵輸送介質(zhì)情況不同，對(duì)于含有嚴(yán)重磨損性的介質(zhì)，請(qǐng)參照表一選擇襯套級(jí)數(shù)。 </p> <p> <br /> 汕頭螺桿泵哪個(gè)廠家質(zhì)量好主要用途之一是診斷泵是怎樣運(yùn)行的和分析井下問(wèn)題。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江門螺桿泵質(zhì)量代理商,螺桿泵"

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?，由于機(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 /> </p><p> 試運(yùn)轉(zhuǎn) </p> <p> 1、污泥螺桿泵切忌干運(yùn)轉(zhuǎn)，哪怕很短時(shí)間空轉(zhuǎn)也會(huì)造成定子的損壞。 </p> <p> 在啟動(dòng)泵前，先將要輸送的介質(zhì)注入泵的吸入腔內(nèi)(若介質(zhì)濃度高，稀釋后注入)。以確保潤(rùn)滑橡膠定子。泵停止運(yùn)轉(zhuǎn)時(shí)，應(yīng)留有足夠的介質(zhì)在吸入腔內(nèi)。用記在設(shè)計(jì)管道時(shí)應(yīng)予以專門考慮。 </p> <p> 2、污泥螺桿泵不能在閥門關(guān)閉時(shí)工作，以避免容積泵的壓力急劇升高而造成管道破裂及泵的損壞。尤其在輸送危險(xiǎn)介質(zhì)時(shí)，安裝壓力開(kāi)關(guān)等安全裝置是尤其重要的。 </p> <p> 3、泵應(yīng)瞬時(shí)通電，確認(rèn)泵的轉(zhuǎn)身與所示的方向相同。 </p> <p> 4、啟動(dòng)前，再一次檢查，多種管道閥門的開(kāi)啟關(guān)閉情況。無(wú)誤時(shí)，方可開(kāi)機(jī)。 </p> <p> 5、輸送易沉淀，易固化介質(zhì)，應(yīng)定期清洗泵及管線。 </p> <p> 6、對(duì)已存放二年以上的泵，應(yīng)對(duì)泵內(nèi)所有的橡膠進(jìn)行更換(包括定子)，發(fā)確保泵的運(yùn)轉(zhuǎn)正常及安全，從而延長(zhǎng)泵的使用壽命。 </p> <p> 維護(hù)與保養(yǎng) </p> <p> <br /> 單螺桿泵能輸送高固體含量的介質(zhì).</p><div

螺桿泵必須按規(guī)定的方向工作，以產(chǎn)生一定的吸力和流量。在工作時(shí)，應(yīng)檢查壓力、溫度和機(jī)械密封。對(duì)于軸封，應(yīng)有輕微泄漏。如果泄漏量不超過(guò)20-30秒/滴，則認(rèn)為是正常的。如果螺桿泵在工作中產(chǎn)生噪聲，則經(jīng)常是由于油溫度低、油粘度高、油中空氣、耦合損失和泵的過(guò)度磨損造成的。 </p> <p> <br /> </p> <p> 3、單螺桿泵停車 </p> <p> 螺桿泵停止后，首先關(guān)閉排氣停止閥，關(guān)閉泵后關(guān)閉吸入截止閥。由于螺桿長(zhǎng)度大，剛性差，螺桿泵容易產(chǎn)生彎曲，造成異常工作，軸系統(tǒng)的連接必須良好，中間工作比較好是在安裝和定位后進(jìn)行，避免管路連接。應(yīng)引起變形，連接管應(yīng)**固定，盡可能減少泵的連接等，另外，備用螺絲比較好在存放期間懸掛和固定，以避免因放置不均勻引起的變形。 </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。珠海螺桿泵歡迎咨詢</p><p style="text-indent:25px">采用填料密封結(jié)構(gòu)的泵，需經(jīng)常檢查介質(zhì)匯漏情況。江門螺桿泵質(zhì)量代理商</p><p> 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。江門螺桿泵質(zhì)量代理商</p><p
