G型單螺桿泵螺桿軸磨損原因分析，G型單螺桿泵螺桿軸磨損五點(diǎn)原因： </p> <p> 1、每種塑料，都有一個(gè)理想塑化的加工溫度范圍，應(yīng)該控制料筒加工溫度，使之接近這個(gè)溫度范圍。粒狀塑料從料斗進(jìn)入料筒，首先會到達(dá)加料段，在加料段必然會出現(xiàn)干性磨擦，當(dāng)這些塑料受熱不足，熔融不均時(shí)，很易造成料筒內(nèi)壁及螺桿表面磨損增大。同樣，在壓縮段和均化段，如果塑料的熔融狀態(tài)紊亂不均，也會造成磨損增快。2、轉(zhuǎn)速應(yīng)調(diào)校得當(dāng)。由于部分塑料加有強(qiáng)化劑，如玻璃纖維、礦物質(zhì)或其他填充料。這些物質(zhì)對金屬材質(zhì)的磨擦力往往比熔融塑料的大得多。在注塑這些塑料時(shí)，如果用高的轉(zhuǎn)速成，則在提高對塑料的剪切力的同時(shí)，亦將令強(qiáng)化相應(yīng)地產(chǎn)生更多被撕碎的纖維，被撕碎的纖維含有鋒利末端，令磨損力大為增加。無機(jī)礦物質(zhì)在金屬表面高速滑行時(shí)，其刮削作用也不小。所以轉(zhuǎn)速不宜調(diào)得太高。

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(dòng)軸等零件。卸下短節(jié)后，即可取出密封盒。對采用機(jī)械密封的，則要非常小心翼翼地進(jìn)行，否則極易造成動(dòng)、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(xiàng)更換、維修的準(zhǔn)備工作。嚴(yán)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(shí)，注意調(diào)整不要過緊。待試車進(jìn)料后逐步壓緊，以介質(zhì)略有滴漏為宜。如機(jī)械密封。則應(yīng)注意動(dòng)、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(hù)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(shí)，橡膠表面涂以潤滑脂(包括轉(zhuǎn)子)，有利于安裝及試運(yùn)轉(zhuǎn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> </p><p style="text-indent:25px">螺桿泵的腐蝕與防護(hù)，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(dá)幾百度，壓力可達(dá)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(qiáng)，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(gè)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(dāng)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。其**簡單的形式（阿基米德螺桿泵）中，一個(gè)單螺桿在一個(gè)圓柱形的空腔中旋轉(zhuǎn)。</p><div

四、避免斷料 </p> <p> <br /> </p> <p> 螺桿泵決不允許在斷料的情形下運(yùn)轉(zhuǎn)，一經(jīng)發(fā)生，橡膠定子由于干摩擦，瞬間產(chǎn)生高溫而燒壞，所以，粉碎機(jī)完好，格柵暢通是螺桿泵正常運(yùn)轉(zhuǎn)的必要條件之一，為此，有些螺桿泵還在泵身上安裝了斷料停機(jī)裝置，當(dāng)發(fā)生斷料時(shí)，由于螺桿泵其有自吸功能的特性，腔體內(nèi)會產(chǎn)生真空，真空裝置會使螺桿泵停止運(yùn)轉(zhuǎn)。五、保持恒定的出口壓力 </p> <p> <br /> </p> <p> 螺桿泵是一種容積式回轉(zhuǎn)泵，當(dāng)出口端受阻以后，壓力會逐漸升高，以至于超過預(yù)定的壓力值。此時(shí)電機(jī)負(fù)荷急劇增加。傳動(dòng)機(jī)械相關(guān)零件的負(fù)載也會超出設(shè)計(jì)值，嚴(yán)重時(shí)會發(fā)生電機(jī)燒毀、傳動(dòng)零件斷裂。為了避免螺桿泵損壞，一般會在螺桿泵出口處會安裝回油閥，用以穩(wěn)定出口壓力，保持泵的正常運(yùn)轉(zhuǎn)。螺桿泵可以用于高粘度流體的輸送和含有硬質(zhì)懸浮顆粒介質(zhì)或含有纖維介質(zhì)的輸送。正規(guī)螺桿泵歡迎咨詢</p><p style="text-indent:25px">單螺桿泵能輸送高固體含量的介質(zhì).茂名螺桿泵歡迎咨詢</p><p> 1、單螺桿泵的啟動(dòng) </p> <p> 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 />
