疲勞失效主要是在交變應(yīng)力作用影響下形成的，一般表現(xiàn)為低應(yīng)力脆性斷裂，且局部性質(zhì)發(fā)生改變。長時間使用后，使得橡膠材料性能發(fā)生變化而產(chǎn)生漏失問題，難以滿足實際工作要求，因此，設(shè)備結(jié)構(gòu)對于設(shè)備密封性具有直接影響。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 3、橡膠襯套剪切應(yīng)力 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 在過盈配合作用影響下，變形抗力在襯套與密封位置產(chǎn)生接觸應(yīng)力，確保相鄰兩個腔室間密封。設(shè)備在運行過程中，轉(zhuǎn)子與液壓力之間會產(chǎn)生剪切力，一旦超過橡膠材料強度，勢必會撕裂橡膠襯套，從而產(chǎn)生漏失，難以滿足生產(chǎn)需求。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 江門螺桿泵制作廠家以略有介質(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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="**螺桿泵廠家直供,螺桿泵"

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 /> </p><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(yīng)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(fù)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(xué)介質(zhì)的腐蝕，但是對***、鹽酸、氫氟酸、鹵素、草酸等的化學(xué)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。螺桿泵抽油的高產(chǎn)率具體做法。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="**螺桿泵廠家直供,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900634765/2986980.jpg"></div><p> 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(jié)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(jié)果，也會給螺桿泵帶來嚴重損壞。使泵排量與流入井底的液量相匹配，就可以提高效率和降低成本。**螺桿泵廠家直供</p><p

4、拆卸轉(zhuǎn)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(zhuǎn)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(yīng)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(yīng)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(yīng)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(zhuǎn)子)，有利于安裝及試運轉(zhuǎn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br
