機(jī)封的安裝位置隨機(jī)械密封型式、吸沙泵種類的不同而不同。安裝時(shí)注意事項(xiàng)1、在安裝、拆卸機(jī)械密封時(shí)要仔細(xì)，嚴(yán)禁動(dòng)用手錘和扁鏟，以免損壞密封元件。如果結(jié)垢拆卸不下時(shí)，應(yīng)清洗干凈后再進(jìn)行拆卸。2、如果在泵兩端都用機(jī)械密封時(shí)，在裝配，拆卸過(guò)程中互相照顧，防止顧此失彼。3、對(duì)運(yùn)行過(guò)的機(jī)械密封，凡有壓蓋松動(dòng)使密封發(fā)生移動(dòng)的情況，則動(dòng)靜環(huán)零件必須更換，不應(yīng)重新上緊繼續(xù)使用。因?yàn)樗蓜?dòng)后摩擦副原來(lái)運(yùn)轉(zhuǎn)軌跡會(huì)發(fā)生變動(dòng)，接觸面的密封性就很容易遭到破壞。吸沙泵啟動(dòng)前的準(zhǔn)備工作1、檢查機(jī)械密封，以及附屬裝置和管線安裝是否齊全，是否符合技術(shù)要求。2、機(jī)械密封啟動(dòng)前進(jìn)行靜壓試驗(yàn)，檢查機(jī)械密封是否有泄漏現(xiàn)象。若泄漏較多，應(yīng)查清原因設(shè)法消除。如仍無(wú)效，則應(yīng)拆卸檢查并重新安裝。一般靜壓試驗(yàn)壓力用2~3公斤/平方厘米。3、按吸沙泵的轉(zhuǎn)動(dòng)方向旋轉(zhuǎn)泵軸，檢查是否輕快均勻。如旋轉(zhuǎn)吃力或不動(dòng)時(shí)，則應(yīng)檢查裝配尺寸是否錯(cuò)誤，安裝是否合理。吸沙泵運(yùn)轉(zhuǎn)時(shí)注意事項(xiàng)1、吸沙泵啟動(dòng)后若有輕微泄漏現(xiàn)象，應(yīng)觀察一段時(shí)間。如連續(xù)運(yùn)行4小時(shí)，泄漏量仍不減小，則應(yīng)停泵檢查。2、吸沙泵的操作壓力應(yīng)平穩(wěn)，壓力波動(dòng)不大于1公斤/平方厘米。3、吸沙泵在運(yùn)轉(zhuǎn)中。太原CR1格蘭富機(jī)械密封CRNCM格蘭富機(jī)械密封。</p><div

對(duì)策：采用雙端面機(jī)械密封，這樣有助于改善潤(rùn)滑條件，提高密封性能。3、由于介質(zhì)引起的滲漏（1）大多數(shù)潛污泵機(jī)械密封拆解后，靜環(huán)和動(dòng)環(huán)的輔助密封件無(wú)彈性，有的已經(jīng)腐爛，造成了機(jī)封的大量滲漏甚至有磨軸的現(xiàn)象。由于高溫、污水中的弱酸、弱堿對(duì)靜環(huán)和動(dòng)環(huán)輔助橡膠密封件的腐蝕作用，造成了機(jī)械滲漏過(guò)大，動(dòng)、靜環(huán)橡膠密封圈材料為丁腈—40，不耐高溫，不耐酸堿，當(dāng)污水為酸性堿性時(shí)易腐蝕。對(duì)策：對(duì)腐蝕性介質(zhì)，橡膠件應(yīng)選用耐高溫、耐弱酸、弱堿的氟橡膠。（2）固體顆粒雜質(zhì)引起的機(jī)械密封滲漏如果固體顆粒進(jìn)入密封端面，將會(huì)劃傷或加快密封端面的磨損，水垢和油污在軸（套）表面的堆積速度超過(guò)摩擦副的磨損速度，致使動(dòng)環(huán)不能補(bǔ)償磨耗位移，硬對(duì)硬摩擦副的運(yùn)轉(zhuǎn)壽命要比硬對(duì)石墨摩擦副的長(zhǎng)，因?yàn)楣腆w顆粒會(huì)嵌入石墨密封環(huán)的密封面內(nèi)。對(duì)策：在固體顆粒容易進(jìn)入的位置應(yīng)選用碳化鎢對(duì)碳化鎢摩擦副的機(jī)械密封。4、因其他問(wèn)題引起的機(jī)械密封滲漏機(jī)械密封中還存在設(shè)計(jì)、選擇、安裝等不夠合理的地方。（1）彈簧壓縮量一定要按規(guī)定進(jìn)行，不允許有過(guò)大或過(guò)小的現(xiàn)象，誤差±2mm，壓縮量過(guò)大增加端面比壓，摩擦熱量過(guò)多，造成密封面熱變形和加速端面磨損。</p><p> 應(yīng)避免發(fā)生抽空現(xiàn)象，以免造成密封面干摩擦及密封破壞。4、密封情況要經(jīng)常檢查。運(yùn)轉(zhuǎn)中，當(dāng)其泄漏超過(guò)標(biāo)準(zhǔn)時(shí)，如2-3日內(nèi)仍無(wú)好轉(zhuǎn)趨勢(shì)，則應(yīng)停泵檢查密封裝置。吸沙泵配置機(jī)械密封的優(yōu)點(diǎn)是密封性好，但機(jī)械密封的造價(jià)成本高，更換不方便也是現(xiàn)實(shí)操作中存在的問(wèn)題。機(jī)械密封一旦發(fā)生損壞，維修成本要比填料密封高出不少。因?yàn)樵诎惭b使用時(shí)應(yīng)格外注意。減少不必要的操作。避免損害機(jī)封。海川泵業(yè)專業(yè)從事吸沙泵、抽沙泵、泥漿泵、混流泵等設(shè)備研發(fā)、生產(chǎn)和銷售。特別是在清淤、采沙、固堤方面，有著豐富的經(jīng)驗(yàn)。我們專注吸沙泵20年，不僅提供高質(zhì)量的產(chǎn)品和行業(yè)整體解決方案，還提供現(xiàn)場(chǎng)安裝服務(wù)，有關(guān)清淤、吸沙方面方案設(shè)計(jì)及設(shè)備問(wèn)題請(qǐng)隨時(shí)聯(lián)系我們。山東格蘭富機(jī)械密封廠家。</p><div

由于所輸送介質(zhì)具有腐蝕性，所以一般選用聚四氟乙烯做為墊片材料。隨著泵使用的領(lǐng)域越來(lái)越廣，所輸送介質(zhì)種類也越來(lái)越多，因此在選用墊片材質(zhì)時(shí)應(yīng)查閱相關(guān)資料或通過(guò)實(shí)驗(yàn)后再做出正確選擇。墊片失效的原因主要有下列幾種情況：1、墊片材質(zhì)內(nèi)部組織或厚度不均勻，以及使用了帶有裂縫或折皺的紙板，使墊片本身形成了間隙，當(dāng)作用在墊片上的力使墊片所產(chǎn)生的彈性變形不足以完全填充這些間隙時(shí)，泄漏也就不可避免了。2、墊片的材質(zhì)與所輸送的介質(zhì)不相適應(yīng)。由于泵所輸送化工產(chǎn)品化學(xué)性質(zhì)的多樣性，以及為提高燃油的燃燒值或改變其燃燒后的生成物而在燃油中增加入了一些少量的添加劑后而使燃油的某些性質(zhì)發(fā)生變化，所以選擇和輸送介質(zhì)相適的墊片材質(zhì)并非易事，因而也經(jīng)常發(fā)生由于不相適應(yīng)而使墊片發(fā)生侵蝕而產(chǎn)生泄漏的現(xiàn)象。3、作用在密封墊片上的壓力不足。由于密封面上總是存在著微觀的凹凸不平，有時(shí)還在密封面上加工出若干環(huán)形溝槽，若保證密封，就必須對(duì)密封墊片施加足夠大的壓力，使其發(fā)生彈性或塑性變形以填充這些間隙。各種墊片材質(zhì)的壓緊力大小通常在密封墊片生產(chǎn)廠家樣本或產(chǎn)品說(shuō)明書中給出，也可通過(guò)實(shí)驗(yàn)決定。陜西格蘭富機(jī)械密封大全。陽(yáng)泉格蘭富機(jī)械密封CR90-5A</p><p

國(guó)產(chǎn)碳化鎢硬質(zhì)合金的物理—力學(xué)性機(jī)械密封對(duì)輔助密封圈材料的要求：1）材料彈性好，特別是要求良好的復(fù)原性，長(zhǎng)久變形要??；2）不受流體介質(zhì)的侵蝕，而且在介質(zhì)中的膨脹和收縮都不大；3）摩擦因數(shù)小和耐磨性好；4）使用溫度范圍要廣，在高、低溫下不粘著、不變硬、脆和失彈；5）要有適當(dāng)?shù)牧W(xué)性能，如扯斷強(qiáng)度及其延伸率、耐壓等，在壓力作用下無(wú)顯著變形，有優(yōu)良的抗撕裂性、耐磨性和耐壓性等；6）便于加工并可得到高的精度；7）抗介質(zhì)腐蝕、溶解、溶脹、老化等性能好，對(duì)介質(zhì)不應(yīng)有污染等。作為輔助密封圈的材料有橡膠、塑料、石棉、膨脹石墨、石墨和金屬脹圈等。橡膠圈是使用**廣的一種輔助密封圈。常用的橡膠密封圈材料有丁腈橡膠、氟橡膠、硅橡膠、氯丁橡膠、丁苯橡膠等。丁腈橡膠是常用的一種耐油橡膠。它是丁二烯和丙烯腈的共聚物。根據(jù)丙烯腈含量多少分成若干種：低丙烯腈（丁腈-18）、中丙烯腈（丁腈-26）和高丙烯腈（丁腈-40）、丙烯腈含量越高，它的耐油性越好，抗張強(qiáng)度、硬度和耐磨性、耐水性增加，透氣性減小。隨之而來(lái)，它在極性溶劑中是溶解度卻增大，耐腐蝕性也受到影響，彈性和耐寒性也變差。丁腈橡膠不耐撓曲，抗撕裂也較差。鄂爾多斯CR4格蘭富機(jī)械密封</p><p
