</p> <p> 給機(jī)封增加冷卻沖洗裝置。 </p> <p> 選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機(jī)械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，淮安管道泵密封批發(fā)價(jià)，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動(dòng)環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動(dòng)環(huán)和動(dòng)環(huán)座的連接松動(dòng)。 </p> <p> 選擇金屬波紋管機(jī)械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機(jī)封中，金屬波紋管取代了普通機(jī)封中的彈簧，省去了動(dòng)環(huán)輔助密封圈，不需要克服動(dòng)環(huán)補(bǔ)償時(shí)與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯(cuò)的效果，淮安管道泵密封批發(fā)價(jià)，淮安管道泵密封批發(fā)價(jià)。

該類泵的機(jī)械密封采用靜止結(jié)構(gòu)（溫度高于200℃泵采用波紋管結(jié)構(gòu)）。一是避免由于高速攪拌產(chǎn)生的熱量；二是防止彈簧傳遞扭矩。 </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“WC-C”結(jié)構(gòu)。在選擇輔助密封材料時(shí)要考慮以下主要因素： </p> <p>

輕油泵機(jī)械密封輔助措施我們采用了密封腔夾套冷卻、無折流板急冷。 </p> <p> 浙江容積泵密封批發(fā)廠影響密封的主要因素有哪些？密封本身質(zhì)量、工藝操作條件、裝配安裝精度、主機(jī)本身精度、密封輔助系統(tǒng)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

對連續(xù)運(yùn)轉(zhuǎn)的設(shè)備,介質(zhì)內(nèi)若含有較多的固體顆粒,此時(shí)選用“硬對硬”結(jié)構(gòu)較好, 在實(shí)際應(yīng)用中選了YG6- YG6, 一般連續(xù)運(yùn)轉(zhuǎn)壽命在800Oh以上; </p> <p> 對間歇性的運(yùn)轉(zhuǎn)設(shè)備,摩擦副選用碳化鎢或碳化硅對特種石墨。 </p> <p> 對金屬波紋管部分進(jìn)行適當(dāng)?shù)臒崽幚砟芟附訋淼臍堄鄳?yīng)力,以避免長期運(yùn)行過程中產(chǎn)生疲勞破裂. </p> <p> 由于在低溫條件下,摩擦副端面的氣化對機(jī)械密封性能影響很大,除選取較適合的材料外,合理選取端面比壓,主要是波紋管的壓縮量,一般比通常使用中所給的壓縮量大15%～30%為宜。在機(jī)械密封元件靠近大氣側(cè)通入25℃左右的冷卻水,以改善摩擦副潤滑環(huán)境。 </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(dòng)和停機(jī)時(shí)，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(jī)械密封的設(shè)計(jì)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(yùn)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(huì)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(diǎn)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(diǎn)是非常重要的。 </p> <p> <br /> </p> 因端面密封載荷的存在，在密封腔缺乏液體時(shí)啟動(dòng)泵而發(fā)生干摩擦。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="淮安管道泵密封批發(fā)價(jià),封"

在新增的水泵中全部采用了機(jī)械密封，與原有水泵的盤根密封形成了鮮明的對比：（1）機(jī)械密封與盤根密封在密封性能上，機(jī)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(tái)循環(huán)水泵、兩臺(tái)射水泵、凝結(jié)水泵共6臺(tái)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(jī)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(jià)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(fèi)用在7000元左右，不計(jì)人工費(fèi)用每臺(tái)水泵每年消耗在2500元左右。而改為機(jī)械密封后費(fèi)用方面每臺(tái)泵的機(jī)械密封價(jià)格在600元左右，至少一個(gè)大修期在3年以上，由于摩擦阻力的降低使電耗每小時(shí)下降8度，全年節(jié)電在58000度，降低成本3萬元左右。因此機(jī)械密封于盤根密封相比優(yōu)勢十分明顯。 </p> <p> <br /> </p> <p> <br /> </p> 機(jī)械密封的密封面要有一定的比壓，從而達(dá)到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。浙江容積泵密封批發(fā)廠</p><p
