式中Qth為實(shí)踐排量，m3÷d；e為公平距，mm；D為轉(zhuǎn)子截面直徑，mm；T為定子導(dǎo)程，mm；n為轉(zhuǎn)子轉(zhuǎn)速，r÷min。 </p> <p> <br /> </p> <p> 螺桿泵的實(shí)踐排量為： </p> <p> <br /> </p> <p>

<br /> </p> <p> 經(jīng)過***檢查，確認(rèn)一切正常后，才可作啟動(dòng)的準(zhǔn)備工作。應(yīng)有以下幾項(xiàng)工作。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （1）關(guān)閉排水管路上的閥門，以降低啟動(dòng)電流； </p> <p> <br />

完成以上準(zhǔn)備工作后，便可啟動(dòng)螺桿泵。啟動(dòng)后待水螺桿泵轉(zhuǎn)速穩(wěn)定，電流表指針擺動(dòng)到指定位置，這時(shí)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(jìn)人正常運(yùn)行。與此同時(shí)還應(yīng)將水封管的閥門打開。 </p> <p> <br /> </p> <p> <br /> </p>

螺桿泵按螺桿數(shù)量分為。 </p> <p> 單螺桿泵——單根螺桿在泵體的內(nèi)螺紋槽中嚙合轉(zhuǎn)動(dòng)的泵。 </p> <p> 雙螺桿泵——由兩個(gè)螺桿相互嚙合輸送液體的泵。 </p> <p> 三螺桿泵——由多個(gè)螺桿相互嚙合輸送液體的泵。單螺桿泵 </p> <p> 是一種單螺桿式輸運(yùn)泵，它的主要工作部件是偏心螺旋體的螺桿（稱轉(zhuǎn)子）和內(nèi)表面呈雙線螺旋面的螺桿襯套（稱定子）。其工作原理是當(dāng)電動(dòng)機(jī)帶動(dòng)泵軸轉(zhuǎn)動(dòng)時(shí)，螺桿一方面繞本身的軸線旋轉(zhuǎn)，另一方面它又沿襯套內(nèi)表面滾動(dòng)，于是形成泵的密封腔室。螺桿每轉(zhuǎn)一周，密封腔內(nèi)的液體向前推進(jìn)一個(gè)螺距，隨著螺桿的連續(xù)轉(zhuǎn)動(dòng)，液體螺旋形方式從一個(gè)密封腔壓向另一個(gè)密封腔，***擠出泵體。螺桿泵是一種新型的輸送液體的機(jī)械，具有結(jié)構(gòu)簡單、工作安全可靠、使用維修方便、出液連續(xù)均勻、壓力穩(wěn)定等優(yōu)點(diǎn)。 </p> <p> <br /> 當(dāng)主動(dòng)螺桿旋轉(zhuǎn)時(shí)，螺桿泵密封容積在螺牙的擠壓下提高螺桿泵壓力，并沿軸向移動(dòng)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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(xiǎn)的腐蝕損壞。

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(shí)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(shí)就會(huì)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(gè)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。

螺桿泵應(yīng)在吸入截止閥完全打開的情況下啟動(dòng)，以防止過載或抽吸。螺桿泵雖然具有干燥和吸收的能力，但必須防止干旋，以免刮傷工作面。當(dāng)油溫較低或粘度很高時(shí)，泵需要啟動(dòng)時(shí)，螺桿泵應(yīng)從吸入閥和旁通閥的完全開啟開始，使泵啟動(dòng)時(shí)的負(fù)荷比較低，直到原動(dòng)機(jī)達(dá)到額定轉(zhuǎn)速為止。旁通閥逐漸關(guān)閉。當(dāng)旁通閥打開時(shí)，液體在節(jié)流狀態(tài)下在泵內(nèi)循環(huán)，循環(huán)油越多，循環(huán)時(shí)間越長，液體的熱越嚴(yán)重，甚至由于高溫變形而損壞泵。必須注意。 </p> <p> <br /> </p> <p> 2、單螺桿泵的運(yùn)行 </p> <p> 螺桿泵必須按規(guī)定的方向工作，以產(chǎn)生一定的吸力和流量。在工作時(shí)，應(yīng)檢查壓力、溫度和機(jī)械密封。對于軸封，應(yīng)有輕微泄漏。如果泄漏量不超過20-30秒/滴，則認(rèn)為是正常的。如果螺桿泵在工作中產(chǎn)生噪聲，則經(jīng)常是由于油溫度低、油粘度高、油中空氣、耦合損失和泵的過度磨損造成的。 </p> <p> <br />
