SMH440R40E6.7W23三螺桿泵、臥式SMH三螺桿泵
三螺桿泵的安裝位置距油面太高，特別是在泵轉(zhuǎn)速降低時，因不能保證泵吸油腔有必要的真空度造成吸油不足而吸入空氣。此時應(yīng)調(diào)整泵與油面的相對高度，使其知足劃定的要求。
The installation position of the three screw pump from the oil surface is too high, especially in the pump speed is reduced, because the vacuum pump suction chamber can not guarantee the necessary degree of suction
caused by insufficient inhalation of air. You should adjust the oil pump and the relative height, make it satisfy formularyrequirement.
吸油濾油器被污物堵塞或其容量過小，導(dǎo)致吸油阻力增加而吸入空氣；另外，進(jìn)、出油口的口徑較大也有可能帶入空氣。此時，可清洗濾油器，或選取較大容量、且進(jìn)出口徑適當(dāng)?shù)臑V油器。三螺桿泵不但能防止吸入空氣，還能防止產(chǎn)生噪聲。
Oil filter is blocked by dirt or its capacity is too small, resulting in increase in inhaled air oil resistance; in addition,inlet, outlet of large caliber may also into the air. At this time, can clean the oil filter, or select a larger capacity,

油箱內(nèi)油量不夠，或吸油管口未插至油面以下，泵便會吸入空氣，此時應(yīng)往油箱內(nèi)增補(bǔ)油液至油標(biāo)線；若回油管口露出油面，有時也會因系統(tǒng)內(nèi)瞬間負(fù)壓而使空氣反灌進(jìn)入系統(tǒng)，所以回油管口一般也應(yīng)插至油面以下。
The amount of oil in the tank is not enough, or the suction nozzle is not inserted into the oil, pump will be inhaled air, at this time should go to the tank added oil to oil line; if the oil return pipe exposed out of the oil surface,
sometimes as a result of system pressure and make the air moment in anti poured into the system, so the oil return pipe generally should be inserted the following to the oil surface.
三螺桿泵的泵體與兩側(cè)端蓋為直接接觸的硬密封，若接觸面的平面度達(dá)不到劃定要求，則泵在工作時輕易吸入空氣；同樣，泵的端蓋與壓蓋之間也為直接接觸，空氣也輕易侵入；若壓蓋為塑料制品，因為其損壞或因溫度變化而變形，也會使密封不嚴(yán)而進(jìn)入空氣。排除這種故障的方法是：當(dāng)泵體或泵蓋的平面度達(dá)不到劃定的要求時，可以在平板上用金鋼砂按字形路線往返研磨，也可以在平面磨床上磨削，使其平面度不超過5μm，并需要保證其平面與孔的垂直度要求；對于泵蓋與壓蓋處的泄漏，可采用涂敷環(huán)氧樹脂等膠粘劑進(jìn)行密封。

泵軸一般采用骨架式油封進(jìn)行密封。若卡緊唇部的彈簧脫落，或?qū)⒂头庋b反，或其唇部被拉傷、老化，都將使油封后端常常處于負(fù)壓狀態(tài)而吸入空氣，一般可更換新油封予以解決

用于點(diǎn)火油泵噴然點(diǎn)火的介質(zhì)主要是輕柴油，輕柴油的特性是粘度很低，3mm2/s~8mm2/s，潤滑性很差，如果輕柴油再含有添加劑的話，那輕柴油表面那層油膜就會遭到破壞，潤滑性就會變得更差，輕柴油的這些特性嚴(yán)重制約著點(diǎn)火油泵——三螺桿泵的使用效果，會令點(diǎn)火油泵很快失效，那怎樣才能保證點(diǎn)火油泵超長的使用壽命呢，除設(shè)備、工藝保證外，材料技術(shù)的合理運(yùn)用也是保證點(diǎn)火油泵良好性能的關(guān)鍵因素之一，黃山天曼能在泵行業(yè)中獨(dú)樹一幟，備受尊崇憑借的不僅是*的設(shè)備、*的工藝，還與我們多年來在材料領(lǐng)域的研究密不可分，以下就是關(guān)于點(diǎn)火油泵材料技術(shù)的基本運(yùn)用，希望能對大家有所幫助。所謂材料技術(shù)，主要包含兩個方面
一：材料合理配置技術(shù)
點(diǎn)火油泵——三螺桿泵在運(yùn)行過程中理論上螺桿與螺桿之間、螺桿與泵套之間是不會接觸的，但實(shí)際是在運(yùn)行過程中零部件相互間是可能會存在局部的接觸，同時由于輸送介質(zhì)粘度低、潤滑性差，這些因素都會造成運(yùn)動部件、與運(yùn)動部件接觸的零件磨損從而縮短泵的使用壽命，所謂合理配置就是指我們要對運(yùn)動部件、與運(yùn)動部件存在接觸的這樣兩個零部件的材料要進(jìn)行合理配置，對三螺桿泵來講，具體表現(xiàn)在三個方面：
1，主動螺桿與從動螺桿之間
2、螺桿與泵套之間
3、機(jī)械密封的動環(huán)與靜環(huán)。
以上三方面材料的合理配置決定著點(diǎn)火油泵的使用效果，那怎樣我們進(jìn)行合理配置呢。我們必須要兩個基本認(rèn)識
1、的、zui耐磨的材料結(jié)合在一起，點(diǎn)火油泵——三螺桿泵的使用效果并不能達(dá)到*，往往效果適得其反。
2、硬對軟的材料組合效果可能會更好
至于點(diǎn)火油泵各個零部件具體采用什么材料還需結(jié)合介質(zhì)特性、現(xiàn)場概況要求來定。
二：材料表面處理技術(shù)
點(diǎn)火油泵所有材料表面必須進(jìn)行處理，表面技術(shù)的應(yīng)用，主要是為了達(dá)到耐磨特性，延長點(diǎn)火油泵的使用壽命，增強(qiáng)了點(diǎn)火油泵的工作可靠性。具體采用什么處理方式還需結(jié)合介質(zhì)特性、現(xiàn)場概況要求來定，象涂覆技術(shù)和表面處理技術(shù)應(yīng)該都是一個不錯的選擇。
高壓三螺桿泵壓力高是因為三螺桿泵的螺桿導(dǎo)成比低壓三螺桿泵的導(dǎo)成多，一般低壓三螺桿泵螺桿的導(dǎo)成是2個或是4個，而高壓三螺桿泵（SM三螺桿泵）它的導(dǎo)成有6個，所以SM三螺桿泵比SN三螺桿泵的工作壓力要高，可能說到整理您還是不明白從哪里可以看出來從哪里可以辨認(rèn)三螺桿泵壓力是高是低，下面就說個簡單的辨認(rèn)方法，當(dāng)您把三螺桿泵拆解了，從泵芯里把螺桿抽出來的時候，看看螺桿泵的長度和螺桿的螺距，三螺桿泵的螺桿越長，螺距越多，那說明這臺三螺桿泵的工作壓力就會越高，相反如果三螺桿泵的螺桿越短，螺距越少那么他的工作壓力就會越低.
螺桿泵因其可變量輸送、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，廣泛地被使用在輸送水、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)計選型方面考慮不周，會給以后的使用、管理、維修帶來麻煩，所以選用的一臺按生產(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。
