第三梯度是國內(nèi)企業(yè)產(chǎn)品。國內(nèi)螺桿泵企業(yè)在技術(shù)上和品牌上處于劣勢，只能通過壓低價(jià)格、提高服務(wù)質(zhì)量、減少交貨周期來贏得客戶，因而價(jià)格往往比進(jìn)口螺桿泵要低20％－30％。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 從產(chǎn)品結(jié)構(gòu)來看，螺桿泵產(chǎn)品種類較多，規(guī)格復(fù)雜，價(jià)格跨度較大。加上一些中小企業(yè)以低廉的價(jià)格進(jìn)行惡性競爭，擾亂了市場價(jià)格。一般而言，原材料等級越高、產(chǎn)品規(guī)格越高的螺桿泵價(jià)格更高。分種類而言，三螺桿泵結(jié)構(gòu)簡單，便于維修，價(jià)格也相對較低。雖然我國國內(nèi)的螺桿泵與國外專業(yè)公司相比還存在差距，但隨著我國螺桿泵科研力量的投入及應(yīng)用實(shí)踐的增多，螺桿泵未來發(fā)展趨勢是開發(fā)低轉(zhuǎn)速，長導(dǎo)程，傳動(dòng)量部件材質(zhì)優(yōu)良，額定壽命長的產(chǎn)品替代原來傳統(tǒng)螺桿泵。 </p> <p> <br /> </p> <p> <br /> </p><p> 污水處理是把廢水、污水集聚在污水池后，通過水泵提升、輸送到污水處理設(shè)備中，達(dá)到分離、凈化及回收再利用的工藝。從水池底部抽取出來，去做污泥處理。 </p> <p> 污泥螺桿泵，主要用在產(chǎn)生污泥的池子，比如沉淀池、污泥池、生化池、過濾池等。污泥螺桿泵把產(chǎn)生的污泥抽送給壓濾機(jī)，壓濾機(jī)把污泥中的水分去除，實(shí)現(xiàn)污泥處理。污泥螺桿泵的壓力大小，決定污泥螺桿泵抽送污泥的含水量大小，對后面的壓濾機(jī)的污泥處理產(chǎn)生直接影響。 </p> <p> 污水處理選用單螺桿泵的優(yōu)點(diǎn) </p> <p> 1.單螺桿泵能輸送高固體含量的介質(zhì)； </p> <p> 2.單螺桿泵流量均勻壓力穩(wěn)定，低轉(zhuǎn)速時(shí)更為明顯； </p> <p> 3.單螺桿泵流量與泵的轉(zhuǎn)速成正比，因而具有良好的變量調(diào)節(jié)性； </p> <p> 4.單螺桿泵一泵多用可以輸送不同粘度的介質(zhì)； </p> <p> 5.單螺桿泵的安裝位置可以任意傾斜； </p> <p> 6.單螺桿泵適合輸送敏性物品和易受離心力等破壞的物品； </p> <p> 7.單螺桿泵體積小，重量輕、噪聲低，結(jié)構(gòu)簡單，維修方便； </p> <p> 8.在輸送介質(zhì)的進(jìn)程中具有不受攪動(dòng)、脈動(dòng)小、無剪切等特點(diǎn)。 </p> <p> <br /> 特點(diǎn)是流量平穩(wěn)、壓力脈動(dòng)小、有一定自吸能力、噪聲低、效率高、壽命長、工作可靠。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="質(zhì)量螺桿泵歡迎選購,螺桿泵"

***梯度是進(jìn)口螺桿泵產(chǎn)品。由于國外企業(yè)具有品牌和技術(shù)上的優(yōu)勢，目前國內(nèi)許多客戶選擇購買從國外進(jìn)口的螺桿泵。由于運(yùn)輸?shù)雀鞣N成本加上國外企業(yè)的定價(jià)往往較高，使得進(jìn)口螺桿泵價(jià)格居高不下。而且由于交貨期長，客戶要滿足生產(chǎn)則往往需要一次性購買較多產(chǎn)品，影響了企業(yè)資金周轉(zhuǎn)。 </p> <p> <br /> </p> <p> 第二梯度是在我國進(jìn)行生產(chǎn)銷售的合資企業(yè)和外資企業(yè)產(chǎn)品。這類企業(yè)具有技術(shù)上的優(yōu)勢，且在國內(nèi)生產(chǎn)，物流周期短，生產(chǎn)成本也得以降低，因而市場價(jià)格相對進(jìn)口產(chǎn)品也有所下調(diào)。 </p> <p> <br />

空泡腐蝕是金屬與液體介質(zhì)之間作高速相對運(yùn)動(dòng)時(shí)，液體介質(zhì)對金屬產(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，稱為沖刷腐蝕。如螺桿泵的葉輪產(chǎn)生沖刷腐蝕后會使螺桿泵的揚(yáng)程和效率***降低，甚至使螺桿泵無法工作，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，也會給螺桿泵帶來嚴(yán)重?fù)p壞。質(zhì)量螺桿泵歡迎選購</p><p
