不同金屬在電解質(zhì)溶液中的電位不同，它們之間會產(chǎn)生電位差；同一金屬由于本身**不均勻在電解質(zhì)溶液中也有可能產(chǎn)生電位差；同一金屬在電解質(zhì)溶液中所處的環(huán)境條件有差別（如濃度、溫度和應(yīng)力差別等）也會產(chǎn)生電位差。而在酸、堿、鹽等電解質(zhì) </p> <p> <br /> </p> <p>

式中，Q為實踐排量，m3÷d；Gv為容積效力，％。上述兩式中公平距、轉(zhuǎn)子截面直徑D、定子導(dǎo)程T都是螺桿泵的構(gòu)造參數(shù)。構(gòu)造參數(shù)肯定后，螺桿泵的實踐排量就只與轉(zhuǎn)速n和容積效力Gv有關(guān)，而容積效力重要與泵的外部走漏量有關(guān)，也即與定子和轉(zhuǎn)子的配合間隙（過盈）以及所舉升介質(zhì)的粘度有關(guān)。

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(jìn)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(jìn)展，使表面缺口向深處擴(kuò)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(qiáng)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(dá)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(jìn)人微裂紋加速了裂紋向深處擴(kuò)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(kuò)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 /> 主要工作部件是偏心螺桿（轉(zhuǎn)子）和固定的襯套（定子）。性能優(yōu)良螺桿泵服務(wù)商</p><p style="text-indent:25px">一部分泵排量受氣干擾而損失，如果消除泵內(nèi)氣的干擾和控制泵的運(yùn)轉(zhuǎn)時間。東莞豪華螺桿泵</p><p> 但是其缺點(diǎn)也是非常明顯：加工精度要求更高，增加了加工的難度，特別是加二精度不夠就會影響轉(zhuǎn)子和定子的配合均勻度，使上述的第4)、5)和6)點(diǎn)優(yōu)點(diǎn)不再存在；而且加工工時多和生產(chǎn)成本較高，這就是目前生產(chǎn)較少的原因。 </p> <p> <br /> </p> <p> 當(dāng)然，也可以制造轉(zhuǎn)子和定子螺旋頭數(shù)更多的單螺桿泵，如三頭螺旋的轉(zhuǎn)子和四頭內(nèi)螺旋定子構(gòu)成的泵等，但對制造精度的要求更髙，且流量并不是總隨螺旋頭 </p> <p> <br /> </p> <p> 增加而增大，故已無多少實際意義。雖然這種更多螺旋頭數(shù)的轉(zhuǎn)子和定子的嚙合副在單螺桿泵中并沒有得到應(yīng)用，但在石油機(jī)械的螺桿鉆具這一領(lǐng)域卻得到了***的應(yīng)用。 </p> <p> <br /> </p> <p> <br /> 東莞豪華螺桿泵</p><p
