螺桿泵的特點及其選用方法，如果螺桿泵在設(shè)計選型方面考慮不周，會給以后的使用、管理、維修帶來麻煩，所以選用的一臺按生產(chǎn)實際需要，合理可靠的螺桿泵既能保證生產(chǎn)順利進行，又可降低修理成本。螺桿泵因其可變量輸送、自吸能力強、可逆轉(zhuǎn)、能輸送含固體顆粒的液體等特點，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。螺桿泵選用應遵循經(jīng)濟、合理、可靠的原則。一、螺桿泵的品質(zhì) </p> <p> <br /> </p> <p> 現(xiàn)在市場上的螺桿泵的種類較多，相對而言，進口的螺桿泵設(shè)計合理，材質(zhì)精良，但價格較高，服務方面有的不到位，配件價格高，訂貨周期長，可能影響生產(chǎn)的正常運行。 </p> <p> <br /> </p><p> 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 </p> <p> <br /> </p> <p> 螺旋泵裝置 </p> <p> 3和外殼4組成的。螺旋泵傾斜裝在上、下水池之間，螺旋泵的下端葉片浸入到水面以下。當泵軸旋轉(zhuǎn)時，螺旋葉片將水池中的水推入葉槽，水在螺旋的旋轉(zhuǎn)葉片作用下，沿螺旋軸一級一級往上提升，直至螺旋泵的出水口。螺旋泵只改變流體的位能，它不同于葉片式水泵將機械能轉(zhuǎn)換為輸送液體的位能和動能。 </p> <p> <br /> 如何保持螺桿泵高效率，螺桿泵的容量大于井的產(chǎn)量或泵吸入口處氣分離不好。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="清遠螺桿泵產(chǎn)品推薦,螺桿泵"

A：”2種方式**終結(jié)果都是調(diào)節(jié)螺桿泵的流量，區(qū)別就是，變頻電機+變頻器是通過改變電機頻率(轉(zhuǎn)速)，實現(xiàn)調(diào)節(jié)流量的效果；自動沖程變速器是通過改變螺桿泵的行程(電機轉(zhuǎn)速不變)，實現(xiàn)現(xiàn)調(diào)節(jié)流量的效果?！?</p> <p> <br /> </p> <p> Q：液壓隔膜計量螺桿泵是否可以配自動沖程變速器呢？ </p> <p> <br /> </p> <p> A：目前我們只有GB/GM2個系列的機械隔膜計量螺桿泵，才能加裝自動沖程控制器 </p> <p> <br /> </p> <p> Q：計量螺桿泵安裝什么情況下得加背壓閥？背壓閥起什么作用？ </p> <p> <br /> </p> <p> A：當計量螺桿泵的進口壓力大于出口壓力的時候，必須加裝背壓閥，否則，進口壓力會將計量螺桿泵單向閥內(nèi)的球頂開，起不到密封的效果，這臺螺桿泵是失效了，我們稱該現(xiàn)象為虹吸現(xiàn)象。 </p> <p> <br /> </p> <p> Q：計量螺桿泵調(diào)節(jié)在多少范圍內(nèi)重復精度可達正負1%？ </p> <p> <br /> </p> <p> A：計量螺桿泵在10%-90%的調(diào)節(jié)范圍內(nèi)，能達到正負1%的重復精度。 </p> <p> <br /> </p> <p> Q：請問廠里JLM電磁驅(qū)動小型微型計量螺桿泵可以做230v嗎？ </p> <p> <br /> </p> <p> A：JLM電磁驅(qū)動小型微型計量螺桿泵只有220V電壓。 </p> <p> <br />

</p> <p> <br /> </p> <p> 腐蝕是材料與環(huán)境發(fā)生反應的結(jié)果。金屬材料與環(huán)境通常發(fā)生化學反應或電化學反應，非金屬材料與環(huán)境則會發(fā)生溶脹、溶解、老化等反應。 (二）腐蝕的類型及機理 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 1.按腐蝕的機理分為化學腐蝕和電化學腐蝕兩大類 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 化學腐蝕是指金屬與干燥的氣體或非電解質(zhì)溶液產(chǎn)生化學作用而引起的腐蝕。化學腐蝕通常為干腐蝕，腐蝕速度相對較小。如碳鋼在鑄造、鍛造、熱處理過程中發(fā)生的高溫氧化以及鋁在無水乙醇中的腐蝕等均屬于此類腐蝕。實際上單純的化學腐蝕是相當少的，一些干燥介質(zhì)中如混人水分常會由化學腐蝕轉(zhuǎn)化為電化學腐蝕。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 電化學腐蝕是指金屬與電解質(zhì)溶液發(fā)生電化學反應而產(chǎn)生的破壞，反應過程均包括陽極反應和陰極反應兩個過程，腐蝕過程中伴有電流的流動，即電子和離子的運動。金屬在酸、堿、鹽等化學溶液和土壤、海水、潮濕的大氣中的腐蝕均屬于此類腐蝕。通常情況下，電化學腐蝕要比化學腐蝕強烈得多，金屬的腐蝕破壞大多數(shù)也是由電化學腐蝕引起的。 </p> <p> <br /> </p> <p>
