螺桿泵業(yè)計(jì)量螺桿泵配件選型指南，隨著工業(yè)化和城市化的進(jìn)程逐步加快，螺桿泵閥制造業(yè)的需求越來(lái)越大，發(fā)展前景異常廣闊。螺桿泵閥產(chǎn)業(yè)是一個(gè)龐大的產(chǎn)業(yè)群體，在國(guó)民經(jīng)濟(jì)建設(shè)中發(fā)揮著重要的作用。目前，我國(guó)螺桿泵閥行業(yè)低端領(lǐng)域已基本實(shí)現(xiàn)國(guó)產(chǎn)化，中**領(lǐng)域亦憑借著成本、服務(wù)等優(yōu)勢(shì)實(shí)現(xiàn)著對(duì)進(jìn)口產(chǎn)品的逐步替代，并致力于螺桿泵閥行業(yè)的國(guó)際化競(jìng)爭(zhēng)中。在過(guò)去的幾十年中，明杰螺桿泵業(yè)的螺桿泵閥產(chǎn)品經(jīng)過(guò)不斷的技術(shù)更新、新品開發(fā)和品牌創(chuàng)新，一直保持著業(yè)界計(jì)量螺桿泵產(chǎn)品技術(shù)的前端地位。在技術(shù)的應(yīng)用，產(chǎn)品性能范圍、應(yīng)用領(lǐng)域、產(chǎn)品質(zhì)量、可靠性、效率、噪聲、振動(dòng)、外觀等多方面突出優(yōu)勢(shì)受到相關(guān)行業(yè)采購(gòu)商的***關(guān)注與青睞。 </p> <p> 螺桿泵定義計(jì)量螺桿泵是一種可以滿足各種嚴(yán)格的工藝流程需要，流量可以在0-**范圍內(nèi)無(wú)級(jí)調(diào)節(jié)，用來(lái)輸送液體（特別是腐蝕性液體）一種特殊容積螺桿泵。計(jì)量螺桿泵也稱定量螺桿泵或比例螺桿泵，計(jì)量螺桿泵屬于往復(fù)式容積螺桿泵，用于精確計(jì)量的，通常要求計(jì)量螺桿泵的穩(wěn)定性精度不超過(guò)±1%。隨著現(xiàn)代化工業(yè)朝著自動(dòng)化操作、遠(yuǎn)距離自動(dòng)控制這一形勢(shì)的不斷發(fā)展，計(jì)量螺桿泵的配套性強(qiáng)、適應(yīng)介質(zhì)（液體）***的優(yōu)勢(shì)尤為顯得突出。

src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900634765/2986980.jpg"></div><p> 三、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)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> 四、避免斷料 </p> <p> 污泥螺桿泵決不允許在斷料的情形下運(yùn)轉(zhuǎn)，一經(jīng)發(fā)生，橡膠定子由于干磨擦，瞬間產(chǎn)生高溫而燒壞，所以，粉碎機(jī)完好，格柵暢通是污泥螺桿泵正常運(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(huì)產(chǎn)生真空，真空裝置會(huì)使螺桿泵停止運(yùn)轉(zhuǎn)。 </p> <p> 五、保持恒定的出口壓力 </p> <p> 污泥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，以至于超過(guò)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(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)。 </p> <p> <br /> </p><p> 1、容積效力的實(shí)踐盤算 </p> <p> <br /> </p> <p> 1、螺桿泵的排量 </p> <p> <br /> </p> <p> 螺桿泵的實(shí)踐排量由下式肯定： </p> <p> <br /> </p> <p> 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> 式中，Q為實(shí)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(shí)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(guò)盈）以及所舉升介質(zhì)的粘度有關(guān)。 </p> <p> <br /> </p> <p> <br /> G型單螺桿泵故障與排除。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="茂名螺桿泵排名靠前,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900322265/6521222.jpg"></div><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 /> 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。口碑好螺桿泵生產(chǎn)廠商</p><p style="text-indent:25px">壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動(dòng)機(jī)直聯(lián)。茂名螺桿泵排名靠前</p><p> 給大家介紹螺桿泵保養(yǎng)技巧： </p> <p> 1、經(jīng)常加脂，電動(dòng)油桶泵為高速運(yùn)轉(zhuǎn)，潤(rùn)滑脂易于揮發(fā)，故必須使軸承處的潤(rùn)滑能保持清潔，并注意添?yè)Q。 </p> <p> 2、螺桿泵經(jīng)常檢查維修，電動(dòng)油桶泵應(yīng)經(jīng)常檢查，維修，須檢查電源線：內(nèi)接線，插頭，開關(guān)是否良好，絕緣電阻是否正常，刷尾座是事松動(dòng)，換向器與電刷接觸良好，電樞繞級(jí)擴(kuò)定子繞組是否是有適中斷路現(xiàn)象，軸承及轉(zhuǎn)動(dòng)零件是否的損壞等等。 </p> <p> 3、注意保存電動(dòng)抽油泵應(yīng)放于干燥，清潔和沒(méi)有腐蝕性氣體的環(huán)境中。 </p> <p> 4、保存好每零件和調(diào)換相同零件，在拆檢螺桿泵時(shí)，應(yīng)保存好每個(gè)零件，要特別注意隔爆零件的隔爆面不能使其損傷拉毛包括絕緣襯墊及套管，如有損壞，必須調(diào)換上新的相同零件，不得采用低于原材料性能的代用材料或原有規(guī)格不符的零件，裝配時(shí)應(yīng)將所有零件按原先位置裝好，不能遺漏。 </p> <p> 5、螺桿泵注意絕緣電阻，長(zhǎng)期擱置不用的或在潮濕環(huán)境中使用的電動(dòng)抽液泵，使用前必須用500伏兆歐表測(cè)量繞組的絕緣電阻。如繞組與電機(jī)殼間絕緣電阻小于7兆歐時(shí)，必須對(duì)繞組進(jìn)行干燥處理。 </p> <p> <br /> 茂名螺桿泵排名靠前</p><p
