溶液中都存在著帶正電荷的陽離子和帶負電荷的陰離子，珠海螺桿泵聯(lián)系人，電位差成了電解質(zhì)溶液中離子移動的推動力，離子移動到電極上得失電子的同時便會產(chǎn)生金屬的腐蝕，并同時產(chǎn)生電流。因此，電化學腐蝕是由于金屬發(fā)生腐蝕電池作用引起的。如果將兩種電位不同的金屬（如銅和鋅）用導線連接起來，放在電解質(zhì)溶液（如?。?SO4溶液）中,這樣就構成了導電回路，回路中的電子將從低電位的鋅流向高電位的銅，電子的移動產(chǎn)生電流，形成腐蝕電池，珠海螺桿泵聯(lián)系人。鋅不斷失去電子，變?yōu)殇\離子進人溶液，鋅電極成為腐蝕電池的極，出現(xiàn)腐蝕；銅電極成為腐蝕電池的陰極而被保護，溶液中的H＋不斷移動到銅電極上得到電子而析出H2，珠海螺桿泵聯(lián)系人。

alt="珠海螺桿泵聯(lián)系人,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876901093750/5238493.jpg"></div><p> G型螺桿泵的橡膠套又名定子，橡膠套內(nèi)壁是橡膠材料制作而成，由于橡膠套與轉(zhuǎn)子（螺桿）之間間隙較小，所以G型單螺桿泵是***禁止空轉(zhuǎn)，必須要有液體使橡膠套與螺桿軸之間有潤滑作用。 </p> <p> 目前，國內(nèi)很多螺桿泵廠家選擇使用新材料改善設備整體性能，延長螺桿泵設備使用壽命，但是，從設備密封性能整體情況來看，螺桿泵密封性能故障存在很多影響因素，具體表現(xiàn)在以下幾個方面: </p> <p> 1、橡膠襯套與轉(zhuǎn)子之間壓力過大 </p> <p> <br /> </p> <p> 在實際螺桿泵的運動過程中，橡膠襯套與轉(zhuǎn)子之間處于過盈狀態(tài)，充分利用過盈接觸，這樣能夠比較大的減少流體漏失。但是，當螺桿泵受到內(nèi)壁壓力、密封腔室間壓差等因素影響時，就會造成接觸壓力下降，從而產(chǎn)生泄漏，降低設備密封性。2、結構參數(shù) </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 湛江螺桿泵制作廠家污泥螺桿泵工作時，液體被吸入后就進入螺紋與泵殼所圍的密封空間。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="珠海螺桿泵聯(lián)系人,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876905917968/581422.jpg"></div><p> 二、螺桿泵的轉(zhuǎn)速選用 </p> <p> <br /> </p> <p> 螺桿泵的流量與轉(zhuǎn)速成線性關系，相對于低轉(zhuǎn)速的螺桿泵，高轉(zhuǎn)速的螺桿泵雖然能增加了流量和揚程，但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長度很短，極易磨損，因而縮短了螺桿泵的使用壽命。 </p> <p> <br /> </p> <p> 三、確保雜物不進入泵體 </p> <p> <br /> </p> <p> 濕污泥中混入的固體雜物會對螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機，也有的安裝格柵裝置或濾網(wǎng)，阻擋雜物進入螺桿泵，對于格柵應及時清撈以免造成堵塞。 </p> <p> <br /> </p><p> 應力腐蝕是指拉應力和腐蝕環(huán)境的聯(lián)合作用而引起的金屬腐蝕破裂，應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)生應力集中，另一方面應力的增大使材料產(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，往往在沒有任何預兆的情況下導致設備的破壞，因此應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，是指金屬材料或結構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)的設備當中，螺桿泵轱等均有可能發(fā)生腐蝕疲勞。

2、螺桿泵經(jīng)常檢查維修，電動油桶泵應經(jīng)常檢查，維修，須檢查電源線：內(nèi)接線，插頭，開關是否良好，絕緣電阻是否正常，刷尾座是事松動，換向器與電刷接觸良好，電樞繞級擴定子繞組是否是有適中斷路現(xiàn)象，軸承及轉(zhuǎn)動零件是否的損壞等等。 </p> <p> 3、注意保存電動抽油泵應放于干燥，清潔和沒有腐蝕性氣體的環(huán)境中。 </p> <p> 4、保存好每零件和調(diào)換相同零件，在拆檢螺桿泵時，應保存好每個零件，要特別注意隔爆零件的隔爆面不能使其損傷拉毛包括絕緣襯墊及套管，如有損壞，必須調(diào)換上新的相同零件，不得采用低于原材料性能的代用材料或原有規(guī)格不符的零件，裝配時應將所有零件按原先位置裝好，不能遺漏。 </p> <p> 5、螺桿泵注意絕緣電阻，長期擱置不用的或在潮濕環(huán)境中使用的電動抽液泵，使用前必須用500伏兆歐表測量繞組的絕緣電阻。如繞組與電機殼間絕緣電阻小于7兆歐時，必須對繞組進行干燥處理。 </p> <p> <br /> 測定井底生產(chǎn)壓力和精確的生產(chǎn)測試數(shù)據(jù)。湛江螺桿泵制作廠家</p><p
