單雙螺桿泵和普通的工作原理及產(chǎn)品介紹，螺桿泵是利用螺桿的回轉(zhuǎn)來(lái)吸排液體的。螺桿為主動(dòng)螺桿，由原動(dòng)機(jī)帶動(dòng)回轉(zhuǎn)，兩邊的螺桿為從動(dòng)螺桿，隨主動(dòng)螺桿作反向旋轉(zhuǎn)。主、從動(dòng)螺桿的螺紋均為雙頭螺紋。由于各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合，在泵的吸入口和排出口之間，就會(huì)被分隔成一個(gè)或多個(gè)密封空間。隨著螺桿的轉(zhuǎn)動(dòng)和嚙合，這些密封空間在泵的吸入端不斷形成，將吸入室中的液體封入其中，并自吸入室沿螺桿軸向連續(xù)地推移至排出端，將封閉在各空間中的液體不斷排出，猶如一螺母在螺紋回轉(zhuǎn)時(shí)被不斷向前推進(jìn)的情形那樣，這就是螺桿泵的基本工作原理。 </p> <p> <br /> </p> <p> 螺桿泵有單螺桿泵、雙螺桿泵和三螺桿泵。 </p> <p> <br /> </p> <p> 螺桿泵的工作原理是：螺桿泵工作時(shí)，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間，當(dāng)主動(dòng)螺桿旋轉(zhuǎn)時(shí)，螺桿泵密封容積在螺牙的擠壓下提高螺桿泵壓力，并沿軸向移動(dòng)。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。 </p> <p> <br /> </p> <p> 螺桿泵特點(diǎn)為：螺桿泵損失小，經(jīng)濟(jì)性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動(dòng)機(jī)直聯(lián)。 </p> <p> <br /> </p> <p> 螺桿泵可以輸送潤(rùn)滑油，輸送燃油，輸送各種油類(lèi)及高分子聚合物，用于輸送黏稠液體。 </p> <p> <br />

第三梯度是國(guó)內(nèi)企業(yè)產(chǎn)品。國(guó)內(nèi)螺桿泵企業(yè)在技術(shù)上和品牌上處于劣勢(shì)，只能通過(guò)壓低價(jià)格、提高服務(wù)質(zhì)量、減少交貨周期來(lái)贏得客戶(hù)，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(lái)看，螺桿泵產(chǎn)品種類(lèi)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(jìng)爭(zhēng)，擾亂了市場(chǎng)價(jià)格。一般而言，原材料等級(jí)越高、產(chǎn)品規(guī)格越高的螺桿泵價(jià)格更高。分種類(lèi)而言，三螺桿泵結(jié)構(gòu)簡(jiǎn)單，便于維修，價(jià)格也相對(duì)較低。雖然我國(guó)國(guó)內(nèi)的螺桿泵與國(guó)外專(zhuān)業(yè)公司相比還存在差距，但隨著我國(guó)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(lái)發(fā)展趨勢(shì)是開(kāi)發(fā)低轉(zhuǎn)速，長(zhǎng)導(dǎo)程，傳動(dòng)量部件材質(zhì)優(yōu)良，額定壽命長(zhǎng)的產(chǎn)品替代原來(lái)傳統(tǒng)螺桿泵。 </p> <p> <br /> </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。 </p> <p> <br /> </p> <p> 3、單螺桿泵停車(chē) </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。 </p> <p> <br /> </p> <p> <br /> 如何保持螺桿泵高效率，螺桿泵的容量大于井的產(chǎn)量或泵吸入口處氣分離不好。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

</p> <p> <br /> </p> <p> 晶間腐蝕先從金屬表面晶粒之間的邊緣開(kāi)始，腐蝕介質(zhì)逐步滲人到金屬的深處，破壞了金屬晶粒之間的結(jié)合力，在金屬表面不會(huì)留下宏觀的跡象，從表面不易發(fā)現(xiàn)，但金屬材料的強(qiáng)度和塑性幾乎完全喪失，只要在很小的外力作用下就可能破壞。比如，不銹鋼經(jīng)過(guò)嚴(yán)重晶間腐蝕后，表面看起來(lái)仍十分光滑，但只要用錘輕輕敲擊，它就會(huì)碎成粉末。由于設(shè)備在工作過(guò)程中晶間腐蝕不容易被發(fā)現(xiàn)，所以它是一種危險(xiǎn)性比較大的腐蝕破壞形式。
