</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，注意調整不要過緊。待試車進料后逐步壓緊，以介質略有滴漏為宜。如機械密封。則應注意動、靜環(huán)上無雜質，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)，河源螺桿泵常用解決方案，有利于安裝及試運轉。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p>

</p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 從產(chǎn)品結構來看，螺桿泵產(chǎn)品種類較多，規(guī)格復雜，價格跨度較大。加上一些中小企業(yè)以低廉的價格進行惡性競爭，擾亂了市場價格。一般而言，原材料等級越高、產(chǎn)品規(guī)格越高的螺桿泵價格更高。分種類而言，三螺桿泵結構簡單，便于維修，價格也相對較低。雖然我國國內(nèi)的螺桿泵與國外專業(yè)公司相比還存在差距，但隨著我國螺桿泵科研力量的投入及應用實踐的增多，螺桿泵未來發(fā)展趨勢是開發(fā)低轉速，長導程，傳動量部件材質優(yōu)良，額定壽命長的產(chǎn)品替代原來傳統(tǒng)螺桿泵。

腐蝕是材料與環(huán)境發(fā)生反應的結果。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溶液產(chǎn)生化學作用而引起的腐蝕?；瘜W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，一些干燥介質中如混人水分常會由化學腐蝕轉化為電化學腐蝕。 </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> <br /> </p><p> 它的重要事情部件是偏愛螺旋體的螺桿（稱轉子）和內(nèi)外貌呈雙線螺旋面的螺桿襯套（稱定子）。其事情原理是當電動機動員泵軸轉動時，螺桿一方面繞自己的軸線旋轉，另一方面它又沿襯套內(nèi)外貌轉動，于是形成泵的密封腔室。螺桿每轉一周，密封腔內(nèi)的液體向前推進一個螺距，隨著螺桿的一連轉動，液體螺旋形方法從一個密封腔壓向另一個密封腔，末了擠出泵體。 </p> <p> 螺桿泵液壓防反轉技能是為防備通例螺桿泵井在停機或卡泵時出現(xiàn)桿柱反轉，造成桿脫、光桿甩彎、地面設置裝備部署破壞等題目標技能。螺桿泵井停機后常會出現(xiàn)桿柱反轉征象，桿柱內(nèi)部儲存的旋轉勢能以及油套壓差都大概導致桿柱反轉。各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合。</p><div style="width:100%;text-align:

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。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)。汕頭螺桿泵廠</p><p

經(jīng)過***檢查，確認一切正常后，才可作啟動的準備工作。應有以下幾項工作。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （1）關閉排水管路上的閥門，以降低啟動電流； </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （2）打開放氣旋塞，向水螺桿泵內(nèi)灌水，同時用手轉動聯(lián)軸器，使葉輪內(nèi)殘存的空氣盡可能排出，直至放氣旋塞有水冒出時，再將其關閉； </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （3）大型水螺桿泵用真空螺桿泵抽氣灌水時，應關閉放氣旋塞及真空表和壓力表的旋塞，以保護儀表的準確性。 3.啟動 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 完成以上準備工作后，便可啟動螺桿泵。啟動后待水螺桿泵轉速穩(wěn)定，電流表指針擺動到指定位置，這時再把真空表及壓力表的旋塞打開，并慢慢開啟出口閥門，水螺桿泵進人正常運行。與此同時還應將水封管的閥門打開。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 螺桿泵啟動后空轉時間不能太長，通常以2～4min為限，如果時間過長，水的溫度就會升高，可能導致汽蝕現(xiàn)象或其他不良后果。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 河源螺桿泵常用解決方案</p><p
