</p> <p> 3、當(dāng)泵送高粘度、含顆?；蚋g性介質(zhì)時(shí)，在泵較長(zhǎng)期停止運(yùn)轉(zhuǎn)前，應(yīng)充分清洗，防止介質(zhì)沉積，然后在整個(gè)系統(tǒng)中用清水或清油循環(huán)洗泵。 </p> <p> 4、注意保持摩擦端表面清潔，防止損壞，尤其動(dòng)靜環(huán)材料為碳化硅時(shí)，因碳化硅很脆，梅州螺桿泵生產(chǎn)工藝，拆裝中必須特別注意，如摩擦端表面損壞，橡膠件破損應(yīng)及時(shí)更換，更換時(shí)必須加潤(rùn)滑脂。 </p> <p>

空泡腐蝕是金屬與液體介質(zhì)之間作高速相對(duì)運(yùn)動(dòng)時(shí)，液體介質(zhì)對(duì)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(huì)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(shí)，由于固體粒子在螺桿泵的過(guò)流部件表面上的沖刷，常常使這些部件產(chǎn)生嚴(yán)重的磨損，稱(chēng)為沖刷腐蝕。如螺桿泵的葉輪產(chǎn)生沖刷腐蝕后會(huì)使螺桿泵的揚(yáng)程和效率***降低，甚至使螺桿泵無(wú)法工作，必須更換新的葉輪。此外，螺桿泵的汽蝕是機(jī)械剝蝕和腐蝕共同作用的結(jié)果，也會(huì)給螺桿泵帶來(lái)嚴(yán)重?fù)p壞。梅州螺桿泵生產(chǎn)工藝但井的條件常不容許將泵置于流體進(jìn)入層下方，則考慮用井下氣分離器。</p><div

輸入污水時(shí)如何合理使用螺桿泵，螺桿泵現(xiàn)如今***的應(yīng)用在污水處理行業(yè)，因?yàn)槠淠軌蜃晕芰?qiáng)、可變量輸送、可逆轉(zhuǎn)、能輸送高粘度、含固體顆粒的液體等突出優(yōu)點(diǎn)，***地被使用在輸送水、濕污泥和絮凝劑藥液方面。 </p> <p> 螺桿泵選用時(shí)如果考慮不周，將會(huì)給以后的使用、管理、維修帶來(lái)巨大的麻煩，因此客戶(hù)在選擇螺桿泵時(shí)必須選用一臺(tái)按生產(chǎn)實(shí)際需要，合理可靠的螺桿泵，這樣既能保證生產(chǎn)順利進(jìn)行，又可降低修理成本。同時(shí)在輸送污水時(shí)還要注意合理使用我妮螺桿泵，現(xiàn)將我們?cè)趹?yīng)用螺桿泵的一些體會(huì)介紹如下：確保雜物不進(jìn)入泵體 </p> <p> 濕污泥中混入的固體雜物會(huì)對(duì)單螺桿泵的橡膠材質(zhì)定子造成損壞，所以必須確保雜物不進(jìn)入單螺桿泵泵的腔體，建議可以在泵前加裝粉碎機(jī)，或者安裝格柵裝置或?yàn)V網(wǎng)以便阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。計(jì)量泵保持恒定的出口壓力 </p> <p> 單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(huì)逐漸升高，甚至將會(huì)超過(guò)預(yù)定的壓力值，增加電機(jī)負(fù)荷，同時(shí)傳動(dòng)機(jī)械相關(guān)零件的負(fù)載也會(huì)超出設(shè)計(jì)值，嚴(yán)重時(shí)會(huì)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(huì)在螺桿泵出口處安裝旁通溢流閥，用以穩(wěn)定出口壓力，保持泵的正常運(yùn)轉(zhuǎn)。離心泵 </p> <p> <br /> </p><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(guān)系，相對(duì)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(yáng)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(guò)早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長(zhǎng)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(jìn)入泵體 </p> <p> <br /> </p> <p> 濕污泥中混入的固體雜物會(huì)對(duì)螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進(jìn)入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機(jī)，也有的安裝格柵裝置或?yàn)V網(wǎng)，阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。 </p> <p> <br /> 各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="梅州螺桿泵生產(chǎn)工藝,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900478515/127892.jpg"></div><p> 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(huì)到達(dá)加料段，在加料段必然會(huì)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(huì)造成磨損增快。 </p> <p> 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(duì)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(duì)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(wú)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。 </p> <p> <br /> 在輸送介質(zhì)的進(jìn)程中具有不受攪動(dòng)、脈動(dòng)小、無(wú)剪切等特點(diǎn).梅州螺桿泵生產(chǎn)工藝</p><p style="text-indent:25px">主要工作部件是偏心螺桿（轉(zhuǎn)子）和固定的襯套（定子）。梅州螺桿泵生產(chǎn)工藝</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(kāi)的情況下啟動(dòng)，以防止過(guò)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(kāi)啟開(kāi)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(kāi)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(zhǎng)，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(duì)于軸封，應(yīng)有輕微泄漏。如果泄漏量不超過(guò)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(guò)度磨損造成的。
