空泡腐蝕是金屬與液體介質(zhì)之間作高速相對運動時，液體介質(zhì)對金屬產(chǎn)生的沖擊加腐蝕的一種腐蝕形式，空泡腐蝕的結果使金屬表面產(chǎn)生蜂窩狀的腐蝕坑。離心螺桿泵葉輪等通常會遭受空泡腐蝕。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 螺桿泵輸送帶有固體顆粒的懸浮液時，由于固體粒子在螺桿泵的過流部件表面上的沖刷，常常使這些部件產(chǎn)生嚴重的磨損，稱為沖刷腐蝕。如螺桿泵的葉輪產(chǎn)生沖刷腐蝕后會使螺桿泵的揚程和效率***降低，甚至使螺桿泵無法工作，必須更換新的葉輪。此外，螺桿泵的汽蝕是機械剝蝕和腐蝕共同作用的結果，也會給螺桿泵帶來嚴重損壞。河源螺桿泵詢問報價根據(jù)泵的大小不同可以輸送粘度從厘泊的介質(zhì)。</p><div

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，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時，水就進入葉片，沿螺旋型流道上升，直至出流。結構簡單，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，轉速低，需設變速裝置。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> 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量輸入原動機的功率、測定井底生產(chǎn)壓力和精確的生產(chǎn)測試數(shù)據(jù)。一般抽油系統(tǒng)的總效率應為50％左右,若低于此應提高其性能。提高總效率的技術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器控制抽油)和換掉過大的電動機。 </p> <p> <br /> </p> <p> 4、井下氣分離。無效的泵運轉常是氣干擾造成的，可通過聲波液面測量和示功圖進行診斷。比較好是將泵吸入口置于流體進入層段的下方，若置于上方則應使用氣體分離器。若閥座短節(jié)布置于流體進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。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="河源螺桿泵詢問報價,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876899248047/2424011.jpg"></div><p style="text-indent:25px">螺桿泵的腐蝕與防護，螺桿泵輸送的液體種類很多，液體的性質(zhì)和螺桿泵的操作條件也是千差萬別的，如液體的溫度可高達幾百度，壓力可達幾十兆帕，有的介質(zhì)呈酸性，有的介質(zhì)呈堿性?有的介質(zhì)腐蝕性強，有的介質(zhì)腐蝕性弱等。為了滿足以上要求，除了采用不同類型的螺桿泵以外，還要了解不同的液體在各種條件下對金屬材料的腐蝕情況，從而針對不同的液體來選擇合適的耐腐蝕螺桿泵用于各類化工生產(chǎn)工藝流程中去，并且采取相應的防腐措施以延長螺桿泵的使用壽命，這也是石油化工用螺桿泵的一個非常重要的問題。多數(shù)螺桿泵是由金屬材料制造的，金屬材料腐蝕的規(guī)律比較復雜，不同的材料在同一種介質(zhì)中的腐蝕情況各不相同，同一種材料在不同介質(zhì)中的腐蝕情況也大相徑庭，比如碳鋼在稀***中腐蝕速度很快，但在濃***中卻相當穩(wěn)定；普通的18-8型奧氏體不銹鋼能耐硝酸、冷磷酸、許多鹽類及堿溶液、水和蒸汽、石油產(chǎn)品等化學介質(zhì)的腐蝕，但是對***、鹽酸、氫氟酸、鹵素、草酸等的化學穩(wěn)定性比較差；鋁在稀***和發(fā)煙***中穩(wěn)定，在中等和高濃度的***中卻不穩(wěn)定。因此，必須首先了解金屬腐蝕的原因和種類，才能針對特定的化工物料，正確選用合適的耐腐蝕螺桿泵并采取合理的防腐措施。應用生產(chǎn)液面測量結合示功圖可了解井是否以比較大產(chǎn)量生產(chǎn)。揭陽螺桿泵承諾守信</p><p

4、拆卸轉子、連桿、短節(jié)、密封盒先卸下三通。卸去鋼絲卡圈或緊定螺釘。退出圓柱銷防落套后，取下圓銷。接下來可分離轉子、連桿、短節(jié)、傳動軸等零件。卸下短節(jié)后，即可取出密封盒。對采用機械密封的，則要非常小心翼翼地進行，否則極易造成動、靜環(huán)的破碎。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 5、重新裝泵前，應做好各項更換、維修的準備工作。嚴格檢查待裝零件的質(zhì)量，清洗是否干凈，外表是否損壞。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 6、裝配步驟正好與拆卸步驟相反。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 7、在裝配填料密封時，注意調(diào)整不要過緊。待試車進料后逐步壓緊，以介質(zhì)略有滴漏為宜。如機械密封。則應注意動、靜環(huán)上無雜質(zhì)，并涂上潤滑脂。靜環(huán)必須平整地裝手密封盒。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 8、連桿節(jié)頭處應檢查橡膠護套是否損壞。在空腔內(nèi)是否充滿潤滑脂。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 9、安裝定子時，橡膠表面涂以潤滑脂(包括轉子)，有利于安裝及試運轉。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />
