給水泵內(nèi)的高壓水雖經(jīng)過密封件，但依然有一定的壓力，蘇州葉輪泵密封經(jīng)銷廠家，為了不讓給水泵內(nèi)的水通過軸與密封件之間的間隙外泄，就從凝結(jié)水泵出口或除鹽水母管引以水源為密封水。 </p> <p> 給水泵內(nèi)的水是具有一定溫度的水，高溫水會通過泵的轉(zhuǎn)軸或泵體金屬把熱量傳遞給軸承，使軸承溫度升高。為了控制熱量外傳，所以密封水也起著冷卻的作用。 </p> <p> 在密封水通過密封件時，水在軸與密封件之間形成水膜，防止在此處軸與密封件之間的間隙外泄，造成大量的工質(zhì)損失；同時高溫給水會通過泵軸和泵體金屬把熱量傳遞給軸承使軸承溫度升高。嚴(yán)重時還會使軸承燒毀；高速旋轉(zhuǎn)的軸與密封件之間的間隙很小，當(dāng)失去密封水時，此處的水膜也就遭到破壞，軸與密封件很可能發(fā)生摩擦，蘇州葉輪泵密封經(jīng)銷廠家，使給水泵振動增大，嚴(yán)重時將造成設(shè)備損壞。密封水的回水一般采用多級水封管引入凝汽器。 </p> <p> <br /> 在實際安裝過程中，應(yīng)該做好對裝配圖的核對工作，蘇州葉輪泵密封經(jīng)銷廠家，并檢各種零件表面是否出現(xiàn)了劃痕、缺點等情況。蘇州葉輪泵密封經(jīng)銷廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

水泵出現(xiàn)滲水的部位主要是兩個部分，一是水泵的軸承密封件，一般此處漏是從水泵的溢流孔流出，此時需要更換水泵；二是水泵的也發(fā)動機(jī)結(jié)合部件的密封件，這里可以單獨更換此零件（提醒大家要注意避免“小病大治”）。 </p> <p> 水泵滲漏的原因：由于水泵設(shè)計原因，水泵軸承收到側(cè)面單邊力量過大，也就是皮帶輪側(cè)偏心力大，容易導(dǎo)致水泵軸承偏磨；加之大家平時急加速的和急收油等加速皮帶對水泵軸承的沖擊（這是從用的角度出發(fā)）；內(nèi)部缺水，水泵軸承得不到冷卻液的潤滑，也會導(dǎo)致密封件損壞（這是從養(yǎng)的角度出發(fā)）；防凍液長時間不更換，雜質(zhì)增加加速磨損（同樣也是養(yǎng)的問題）；南通葉輪泵密封哪家比較好機(jī)械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機(jī)械密封，耐高壓、耐腐蝕機(jī)械密封等。</p><div

造成泄漏的原因主要有兩個方面：一是密封面上有間隙。二是密封部位兩側(cè)存在壓力差，消除或減小任何一個因素都可以阻止或減小泄漏，達(dá)到密封的目的。泵的設(shè)計壓力和使用壓力是客觀存在不能減小，所以泵的密封該解決的是消除或減小密封面之間的間隙。這種間隙包括密封面之間的間隙和密封裝置本生內(nèi)部的間隙。 </p> <p> <br /> </p><p> 低溫輕烴泵用機(jī)械密封 </p> <p> 多彈簧機(jī)械密封采用靜止結(jié)構(gòu)。 </p> <p> 采取增加非補(bǔ)償環(huán)尾部長度和采用副后蓋結(jié)構(gòu)等措施，增加輕烴泵機(jī)械密封的抗抽空能力。 </p> <p> 采用靜環(huán)背冷措施。 </p> <p> 對介質(zhì)易汽化的輕烴泵軸封我們增設(shè)背部冷卻,在軸封正常操作時,可對端面溫度進(jìn)行調(diào)節(jié),使相變半徑靠近內(nèi)徑,增大液膜比例。在泵抽空時,由于端面溫度降低,使閃蒸壓力降低,對防止端面分離有積極作用。 </p> <p> 摩擦副材料的選取。 </p> <p> 對摩擦副材料的選取我們采用“SiC-C”結(jié)構(gòu)。輔助密封材料選擇耐低溫的硅橡膠材料。 </p> <p> 采用自沖洗措施。 </p> <p> 通過沖洗來提高密封腔壓力以防止抽空造成的密封干摩擦。自沖洗措施不僅可保證密封腔內(nèi)有較高的介質(zhì)壓力,避免介質(zhì)在密封腔內(nèi)汽化或氣體積聚,而且還可把摩擦副產(chǎn)生的摩擦熱及時帶走,有效控制密封端面溫升,增大液相面積,改善摩擦狀態(tài)。根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及選擇潤滑、沖洗、保溫、冷卻機(jī)械密封循環(huán)保護(hù)系統(tǒng)等。</p><div

高溫重質(zhì)油泵的介質(zhì)具有以下共同的特點: </p> <p> 溫度高:一般在340一400℃; </p> <p> 介質(zhì)粘度大:在溫度下一般運(yùn)動粘度為(12一180)X 10一6m/s; </p> <p> 介質(zhì)有顆粒:如催化劑、焦炭、含有砂粒等其他雜質(zhì)。 </p> <p> 對于高溫重油介質(zhì)泵用機(jī)械密封?，F(xiàn)在各個企業(yè)都采用焊接金屬波紋管械密封?，F(xiàn)在使用情況較好的有DBM型、XL-604/606/609型、YH-604/606/609型等。波紋管材料采用八AM350、INCONEL718、哈氏B、C等不銹鋼;耐腐蝕高溫合金等，有的波片采用雙層結(jié)構(gòu)，使其承壓力從2MPa上升到5MPa，這些都有效解決了波紋紋管的失彈問題。密封件必須避開強(qiáng)光照射，避免密封件被空氣中臭氧侵蝕或提早老化。蘇州葉輪泵密封哪家質(zhì)量好</p><p

機(jī)械密封裝配前的檢查有哪些內(nèi)容？答：一般性檢查：主要檢查個零件的型號、規(guī)格、性能、配合尺寸及有無缺口、點坑、變形和裂紋等損傷。動、靜環(huán)的檢查：密封端面要光潔明亮、物崩邊、點坑、溝槽、劃痕等缺點。對石墨環(huán)，還要浸沒有檢查是否有裂紋。 </p> <p> .機(jī)械密封彈簧的檢查都包括哪些內(nèi)容？答：彈簧的檢查包括：總?cè)?shù)、有效圈數(shù)、自由高度、軸心對端面是否垂直、彈簧旋向。但彈簧必須檢查旋向，多彈簧不需要檢查旋向。新彈簧要檢查其原始自由高度，自由高度要測量，并與原始記錄比較，殘余變形過大的要更換掉。舊彈簧清洗干凈后，要測量其彈力，彈力減少20%的要更換掉。多彈簧機(jī)械密封，各彈簧自由高度差不得小于0.5mm。蘇州葉輪泵密封經(jīng)銷廠家</p><p
