在新增的水泵中全部采用了機械密封，與原有水泵的盤根密封形成了鮮明的對比：（1）機械密封與盤根密封在密封性能上，機械密封要比盤根密封漏泄量小的多，*為盤根密封漏泄量的1%。（2）使用壽命長，兩年以內(nèi)無需更換，以往盤根密封每60天左右就要進(jìn)行一次更換。（3）消耗功率較少同比盤根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過摸索對比先后將車間的兩臺循環(huán)水泵、兩臺射水泵、凝結(jié)水泵共6臺泵進(jìn)行了進(jìn)行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機械密封前，每年至少要更換4次油盤根，每次更換量在1公斤左右，市場價格30元.，由于盤根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費用在7000元左右，不計人工費用每臺水泵每年消耗在2500元左右。而改為機械密封后費用方面每臺泵的機械密封價格在600元左右，至少一個大修期在3年以上，由于摩擦阻力的降低使電耗每小時下降8度，全年節(jié)電在58000度，降低成本3萬元左右。因此機械密封于盤根密封相比優(yōu)勢十分明顯。 </p> <p> <br /> </p> <p> <br /> </p> </p><p> 泵用機械密封是精密的部件，制造精度及安裝精度要求都很嚴(yán)格，如果裝配不當(dāng)就會影響密封性能，要正確安裝必須注意以下幾點： </p> <p> 泵用機械密封的冷卻和沖洗 </p> <p> 第一種冷卻形式由水泵的出口或高壓端，將輸送的干凈介質(zhì)，直接沖洗密封端面，然后進(jìn)入泵腔內(nèi)，通過介質(zhì)的不斷循環(huán)，將磨擦端面的的磨擦熱帶走達(dá)到冷卻的效果。 </p> <p> 第二種冷卻方式在第一種冷卻形式的基礎(chǔ)上在靜環(huán)的背部增加一冷卻水套，冷卻效果有所改善，并可以沖洗，收集泄露出來的液體。當(dāng)密封介質(zhì)溫度＞150℃時除了在冷卻水套中通過冷卻水及靜環(huán)背部冷卻外，應(yīng)采取強制冷卻措施。即從泵出口的干凈介質(zhì)應(yīng)預(yù)先經(jīng)熱交換器冷卻至50℃時。再進(jìn)入密封腔冷卻沖洗，該形式是冷卻效果**良好的一種。 </p> <p> 如介質(zhì)中含有顆?；螂s質(zhì)，必須采用過濾措施，把常溫干凈沖洗液輸入密封腔內(nèi)。 O形密封圈雖然密封可靠，但如果不注意使用條件，也會發(fā)生泄漏。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

機械密封件屬于精密、結(jié)構(gòu)較為復(fù)雜的機械基礎(chǔ)元件之一，是各種泵類設(shè)備的關(guān)鍵部件。對于機泵，超過50%機率的泄露問題產(chǎn)生原因往往就在機械密封上！ </p> <p> 機械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機械密封，耐高壓、耐腐蝕機械密封，耐顆粒介質(zhì)機械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機械密封。 </p> <p> 選型的主要參數(shù)有：密封腔體壓力（MPa）、流體溫度（℃）、工作速度（m/s）、流體的特性以及安裝密封的有效空間等。 </p> <p> <p> 根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。 </p> <p> 根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動壓式或非接觸型。 </p> <p> 根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤滑、沖洗、保溫、冷卻等機械密封循環(huán)保護(hù)系統(tǒng)等。 </p> <p> 根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。 </p> 軸封腔壓力很高或者壓力接近該密封使用比較高極限時，由密封腔引液體至低壓區(qū)，使軸封液體流動以帶走摩擦熱?；窗搽x心泵密封源頭直供廠家</p><p style="text-indent:25px">為了比較大發(fā)揮機械密封的實際性能，應(yīng)對密封環(huán)的使用進(jìn)行調(diào)查，掌握其工作壓力、溫度等情況，合理進(jìn)行選擇。浙江清水密封制造廠家</p><p> <p> 在液泵的正常操作中，旋轉(zhuǎn)面和靜止面之間因填料盒中的液體所產(chǎn)生的壓力而使其保持在密封狀態(tài)，在起動和停機時，填料盒的壓力由彈簧產(chǎn)生的壓力維持(甚至可以由彈簧的壓力來代替)。 </p> <p> 大部分機械密封的設(shè)計采用較軟的材料來制作旋轉(zhuǎn)面，使其在較硬的靜止面上旋轉(zhuǎn)摩擦。多年來，**通用的組合是利用碳材料作為旋轉(zhuǎn)面，使其在陶瓷靜止面上運行。這類材料目前仍在普遍使用，但靜止面則選用不銹鋼或更硬的材料制作，例如碳化鎢或碳化硅。 </p> <p> 不管采用什么材料，總之在接觸面之間必須保持一層液體薄膜，以起到潤滑的作用。然而，在填料盒內(nèi)，采用彈簧負(fù)載和液體壓力相結(jié)合的方式，可以使密封面之間起到很好的密封作用。但密封壓力太高，則會影響接觸面之間形成液體薄膜，導(dǎo)致熱量增加和過早的磨損。如果密封壓力太低，接觸面之間的間隙增大，容易造成液體泄漏。 </p> <p> 密封制造廠正在不斷地努力提高接觸面的平直度，他們采用特殊的拋光板進(jìn)行研磨。然后，采用單色光源的光柵板對其檢測。從這一觀點出發(fā)，對這些密封接觸面必須小心處理，并嚴(yán)格按照安裝說明，保證密封面得到適當(dāng)?shù)谋Ｗo(hù)和正確就位，這一點是非常重要的。 </p> <p> <br /> </p> 浙江清水密封制造廠家</p><p
