材料（通常是指金屬材料）或材料的性質(zhì)由于與它所處的環(huán)境發(fā)生反應(yīng)而惡化變質(zhì)，稱為腐蝕。它包括三個(gè)方面的研究?jī)?nèi)容，即材料、環(huán)境及反應(yīng)的種類。 </p> <p> <br /> </p> <p> 材料 </p> <p> <br /> </p> <p>

環(huán)境是腐蝕發(fā)生的外部條件，任何材料在使用過程中總是處于特定的環(huán)境中，對(duì)腐蝕起作用的環(huán)境因素主要有介質(zhì)的成分、濃度、溫度，佛山螺桿泵性價(jià)比高、流速和壓力等，佛山螺桿泵性價(jià)比高。 </p> <p> <br /> </p> <p> <br />

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 /> </p> <p> 3、單螺桿泵停車 </p> <p> 螺桿泵停止后，首先關(guān)閉排氣停止閥，關(guān)閉泵后關(guān)閉吸入截止閥。由于螺桿長(zhǎng)度大，剛性差，螺桿泵容易產(chǎn)生彎曲，造成異常工作，軸系統(tǒng)的連接必須良好，中間工作比較好是在安裝和定位后進(jìn)行，避免管路連接。應(yīng)引起變形，連接管應(yīng)**固定，盡可能減少泵的連接等，另外，備用螺絲比較好在存放期間懸掛和固定，以避免因放置不均勻引起的變形。

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。在過去的幾十年中，明杰螺桿泵業(yè)的螺桿泵閥產(chǎn)品經(jīng)過不斷的技術(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)無級(jí)調(diào)節(jié)，用來輸送液體（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±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。 </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 3.水泵不出水： </p> <p> <br /> </p> <p> 產(chǎn)生原因：泵體和吸水管沒灌滿引水；動(dòng)水位低于水泵濾水管；吸水管破裂等。螺桿泵因其有可變量輸送、自吸能力強(qiáng)、可逆轉(zhuǎn)、能輸送含固體顆粒的液體等特點(diǎn)，在污水處理廠中，***地被使用在輸送水、濕污泥和絮凝劑藥液方面。螺桿泵選用應(yīng)遵循經(jīng)濟(jì)、合理、可靠的原則。如果在設(shè)計(jì)選型方面考慮不周，會(huì)給以后的使用、管理、維修帶來麻煩，所以選用一臺(tái)按生產(chǎn)實(shí)際需要，合理可靠的螺桿泵既能保證生產(chǎn)順利進(jìn)行，又可降低修理成本。
