污水泵填料筒的徑向尺寸和軸向尺寸較小，影響了機械密封的安裝。在滿足強度的情況下，將填料筒的內(nèi)徑相應(yīng)地擴大;若有軸套，可將軸套的外徑相應(yīng)地縮小或?qū)⑤S套拆除。 </p> <p> 2.主要尺寸確定 </p> <p> (1)確定傳動套或彈簧座在軸套上的位置。如圖3所示。為了防止傳動套或彈簧座同填料內(nèi)套端面碰，把安裝機械密封的起點尺寸定為[H-K=5～15mm]。 </p> <p> (2)確定軸套總長度。軸套的總長度一般比原來的總長度稍稍長一點。因為考慮到軸套尾端部分要伸出密封壓蓋5～10mm左右，以利于安裝方便。尺寸根據(jù)設(shè)計的密封壓蓋厚度而定。常州機械密封制造廠家熱裂是高溫油泵，如油渣泵、回?zé)捰捅?、常減壓塔底泵等常見的失效現(xiàn)象。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">軸封（shaftseal）一種摩擦密封或填料函，用以防止壓縮機或其他流體輸送設(shè)備軸與軸承之間的液體泄漏。軸封是防止泵軸與殼體處泄漏而設(shè)置的密封裝置常用的軸封型式有填料密封、機械密封和動力封。往復(fù)泵的軸封通常是填料密封。當(dāng)輸送不允許泄漏介質(zhì)時，可采用隔膜式往復(fù)泵。旋轉(zhuǎn)式泵(含葉片式泵、轉(zhuǎn)子泵等)的軸封主要有填料密封、機械密封和動力密封。填料密封填料密封結(jié)構(gòu)簡單、價格便宜、維修方便。但泄漏量大、功耗損失大。因此填料密封用于輸送一般介質(zhì)，如水等;一般不適用于石油及化工介質(zhì)，特別是不能用在貴重、易爆和有危害介質(zhì)中。機械密封機械密封(也稱端面密封)的密封效果好，泄漏量很小，壽命長，但價格貴，加工安裝維修保養(yǎng)比一般密封要求高。機械密封適用于輸送石油及化工介質(zhì)，可用于各種不同粘度、強腐蝕性和含顆粒的介質(zhì)。美國石油學(xué)會標(biāo)準(zhǔn)API610(第8版)規(guī)定:除用戶有規(guī)定外，應(yīng)當(dāng)裝備集裝式機械密封。</p><p> 機械密封是一種依靠彈性元件對靜、動環(huán)端面密封副的預(yù)緊和介質(zhì)壓力與彈性元件壓力的壓緊而達到密封的軸向端面密封裝置，故又稱端面密封。 </p> <p> 其中動環(huán)和靜環(huán)的端面組成一對摩擦副，動環(huán)靠密封室中液體的壓力和彈性元件的推力使其壓緊在靜環(huán)端面上，并在兩環(huán)端面上產(chǎn)生適當(dāng)?shù)谋葔汉捅３忠粚訕O薄的液體膜而達到密封的目的。 </p> <p> 機械密封被廣泛應(yīng)用于工業(yè)泵產(chǎn)品中，尤其在石油化工領(lǐng)域內(nèi)的存在易燃、易爆、易揮發(fā)、劇毒等介質(zhì)場所，在國內(nèi)選煤、選礦行業(yè)中泵上的應(yīng)用也越來越普遍。 </p> <p> 其主要有以下優(yōu)點： </p> <p> ⑴.密封效果好，可達到介質(zhì)無泄露; </p> <p> ⑵.壽命長，在普通泵中一般可運行1~2年或更長時間;MAAG泵的機械密封在正常使用中壽命可達5~10年以上; </p> <p> ⑶.對軸(或軸套)無磨損; </p> <p> ⑷.適用范圍廣，可在目前常用介質(zhì)、轉(zhuǎn)速、溫度、壓力及軸徑條件下使用; 在使用單彈簧的機械密封時，忽略彈簧的旋轉(zhuǎn)方向與泵轉(zhuǎn)子轉(zhuǎn)動方向的正確組合也時有發(fā)生。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="常州機械密封制造廠家,密封"
