<p> 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，以略有介質(zhì)滴出為宜。調(diào)整填料壓蓋，若壓得過緊會使填料的相對轉(zhuǎn)動處因過熱而加磨損。更換填料時，應(yīng)全部更換，軸若磨損嚴(yán)重也應(yīng)更換。 </p> <p> <br /> </p> <p> <br /> </p> <p> 拆卸與零件的更換 </p> <p> <br /> </p> <p> 1、泵在拆卸前，須先行脫離動力端，以防止人身***的發(fā)生，云浮螺桿泵排名靠前。 </p> <p> <br /> </p> <p> 2、拆卸泵頭，卸下泵頭固定螺母，云浮螺桿泵排名靠前，取下泵頭。如無泵頭而只有輸出法蘭的泵，可不用拆下法蘭，便于下一步拉出定子。需要更換定子時拆下此法蘭。 </p> <p> <br /> </p> <p> 3、借助工具拉出定子。 </p> <p> <br /> </p> <p> <br /> </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。云浮螺桿泵排名靠前</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

點腐蝕是由局部電作用引起的，腐蝕從金屬表面開始，***產(chǎn)生凹坑，凹坑可能會被腐蝕產(chǎn)物覆蓋，結(jié)成瘤狀形的硬疤，疤的下面就是一個點蝕坑。點蝕經(jīng)常發(fā)生在金屬表面上有停滯或緩慢流動介質(zhì)的區(qū)域。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 晶間腐蝕先從金屬表面晶粒之間的邊緣開始，腐蝕介質(zhì)逐步滲人到金屬的深處，破壞了金屬晶粒之間的結(jié)合力，在金屬表面不會留下宏觀的跡象，從表面不易發(fā)現(xiàn)，但金屬材料的強度和塑性幾乎完全喪失，只要在很小的外力作用下就可能破壞。比如，不銹鋼經(jīng)過嚴(yán)重晶間腐蝕后，表面看起來仍十分光滑，但只要用錘輕輕敲擊，它就會碎成粉末。由于設(shè)備在工作過程中晶間腐蝕不容易被發(fā)現(xiàn)，所以它是一種危險性比較大的腐蝕破壞形式。 </p> <p> <br /> </p> <p> <br /> 云浮螺桿泵排名靠前測定泵充滿系數(shù)百分率，應(yīng)用綜合數(shù)據(jù)采集系統(tǒng)可同時獲得馬達功率和示功數(shù)據(jù)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

在螺桿泵的水力特征檢測中，輕易涌現(xiàn)容積效力大于100％的狀況，同時螺桿泵實踐排量的盤算方式存在爭議，為處理這個問題筆者在對螺桿泵水力特征實驗數(shù)據(jù)和檢測體系鉆研基本上，展開了螺桿泵容積效力的鉆研，對螺桿泵容積效力的檢測提出了幾點熟悉。 </p> <p> 螺桿泵是一種旋轉(zhuǎn)容積泵，其容積效力隨壓力的降低而降落，額外壓力下的容積效力大小是判斷泵及格與否的重要根據(jù)。在螺桿泵的水力特征實驗中，會涌現(xiàn)容積效力大于100％的狀況，一種是在零壓力點和非零壓力點下都涌現(xiàn)容積效力大于100％，同時在零壓力點容積效力為100％時在非零壓力點也會涌現(xiàn)容積效力大于100％的狀況。針對這個問題筆者對螺桿泵容積效力展開了實驗鉆研，并對實驗數(shù)據(jù)進行了剖析。 </p> <p> <br /> </p><p> 2.按腐蝕的破壞特征，可分為***腐蝕和局部腐蝕 </p> <p> <br /> </p> <p> ***腐蝕也稱為均勻腐蝕，它的特點是腐蝕均勻地發(fā)生在整個金屬的表面，腐蝕的結(jié)果是設(shè)備壁厚的均勻減薄。***腐蝕容易被發(fā)現(xiàn)和測量，因此這種臠蝕的危險性較小，只要在螺桿泵的設(shè)計時考慮足夠的腐蝕裕量就可以保證螺桿泵的機械強度和*吏用壽命。 </p> <p> <br /> </p> <p> 局部腐蝕又稱為非均勻腐蝕，它的特點是腐蝕集中在金屬表面的一定區(qū)域，而其他區(qū)域不腐蝕或腐蝕很輕微。這類腐蝕又包括區(qū)域腐蝕、點腐蝕、晶間腐蝕、應(yīng)力腐蝕、腐蝕疲勞和空泡腐蝕等。 </p> <p> <br /> </p> <p> <br /> 單螺桿泵一泵多用可以輸送不同粘度的介質(zhì).</p><div style="width:100%;text-align:

應(yīng)力腐蝕是指拉應(yīng)力和腐蝕環(huán)境的聯(lián)合作用而引起的金屬腐蝕破裂，應(yīng)力和腐蝕是相互促進的。一方面腐蝕使金屬有效截面積減小和表面形成缺口產(chǎn)生應(yīng)力集中，另一方面應(yīng)力的增大使材料產(chǎn)生大的變形又加速了腐蝕的進展，使表面缺口向深處擴展，往往在沒有任何預(yù)兆的情況下導(dǎo)致設(shè)備的破壞，因此應(yīng)力腐蝕破裂也是一種很危險的腐蝕損壞。 </p> <p> <br /> </p> <p> 腐蝕疲勞又稱疲勞腐蝕，是指金屬材料或結(jié)構(gòu)在交變載荷和腐蝕介質(zhì)共同作用下引起的疲勞強度或疲勞壽命降低的現(xiàn)象。材料在長時間的交變載荷作用下，應(yīng)力值達到或超過材私的疲勞極限時就會使金屬表面產(chǎn)生微小裂紋，腐蝕介質(zhì)進人微裂紋加速了裂紋向深處擴展:***可能造成金屬構(gòu)件突然斷裂，從宏觀上看，斷口有兩個明顯不同的區(qū)域：一是腐蝕疲勞裂紋的產(chǎn)生和擴展區(qū)，二是截面嶄新的***斷裂區(qū)。在石油化工生產(chǎn)行業(yè)的設(shè)備當(dāng)中，螺桿泵轱等均有可能發(fā)生腐蝕疲勞。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 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。云浮螺桿泵排名靠前</p><p style="text-indent:25px">能使泵長期可靠工作的先決條件——應(yīng)使泵有良好的潤滑。云浮螺桿泵排名靠前</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(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(zhuǎn)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(yīng)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。云浮螺桿泵排名靠前</p><p
