三、區(qū)分骨架油封型號(hào)C型骨架油封為內(nèi)骨架油封可分為SC型、TC型、VC型、KC型、DC型這五種，分別是單唇內(nèi)骨架油封、雙唇內(nèi)骨架油封、單唇無(wú)簧內(nèi)骨架油封、雙唇無(wú)簧內(nèi)骨架油封、雙唇雙簧內(nèi)骨架油封。G型骨架油封是外出有螺紋狀，其類(lèi)型和C型一樣，只是在工藝上在外側(cè)修改成有螺紋狀，類(lèi)似于O型圈的作用，即起到加強(qiáng)密封效果的作用，還能起到固定油封不松動(dòng)。B型骨架油封是骨架內(nèi)側(cè)有膠料或者骨架內(nèi)外都沒(méi)有膠料，沒(méi)有膠料會(huì)讓散熱性能更好。A型骨架油封是裝配式油封，結(jié)構(gòu)相對(duì)上述三種相對(duì)復(fù)雜，特點(diǎn)是承壓性能更好更優(yōu)異。四、骨架油封的密封原理及應(yīng)用?骨架油封共分三部分：自緊彈簧、密封主體、加強(qiáng)骨架。?骨架油封的密封原理：由于在油封與軸之間存在著油封刃口控制的油膜，此油膜具有流體潤(rùn)滑特性。?密封原理解析：骨架油封的作用下，油膜的剛度恰好使油膜與空氣接觸端形成一個(gè)新月面，防止了工作介質(zhì)的泄漏，從而實(shí)現(xiàn)旋轉(zhuǎn)軸的密封。油封的密封能力，取決于密封面油膜的厚度，厚度過(guò)大，油封泄漏；厚度過(guò)小，可能發(fā)生干摩擦，引起油封和軸磨損；密封唇與軸之間沒(méi)有油膜，則易引起發(fā)熱、磨損。因此，在安裝時(shí)，必須在密封圈上涂些油，同時(shí)保證骨架油封與軸心線垂直。CDL8-2/1機(jī)械密封安徽109-25機(jī)械密封件。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="CDL8-2/1機(jī)械密封,機(jī)械密封"

普通油封的使用壓力一般不超過(guò)。當(dāng)工作壓力超過(guò)這個(gè)值時(shí)應(yīng)選用耐壓型油封。在同一直徑條件下，不同材料制造的油封，適應(yīng)軸面旋轉(zhuǎn)線速度的能力不同。油封使用的線速度范圍一般小于15m/s。油封的工作范圍與油封使用的材料有關(guān)：材料為丁腈橡膠(NBR)時(shí)為-40~120℃，亞力克橡膠(ACM)-30~180℃，氟橡膠(FPM)-25~300℃。七、對(duì)應(yīng)軸及腔體的設(shè)計(jì)要求軸的設(shè)計(jì)：1、表面粗糙度，由于軸的速度與油量不同，一般軸的粗糙度過(guò)大或過(guò)小，都會(huì)影響到油封的泄漏與磨損。軸的表面粗糙度容許范圍為～μm；～μm。對(duì)旋轉(zhuǎn)軸用油封取～μmRz。2、硬度，旋轉(zhuǎn)軸的表面硬度一般取≥35HRC。當(dāng)介質(zhì)較臟，有來(lái)自外界的污染雜質(zhì)，或軸表速度>12m/s時(shí)，軸表面硬度應(yīng)為55HRC以上，軸表面淬火層深度>。3、軸的倒角，推薦值15°~30°，以能讓油封確實(shí)裝入，不損傷油封唇緣為原則。4、軸的加工，正確的軸加工是保證密封系統(tǒng)正常工作的決定性因素，適宜的油封軸加工方法是橫向給進(jìn)精研磨，金剛砂紙磨光。不適宜的加工方法是在車(chē)床上精加工，超精加工，滾光加工，金剛砂紙磨光（砂紙?jiān)谳S向移動(dòng)磨光）。5、軸的材料，主要是普通碳素結(jié)構(gòu)鋼，如C35和C45，另外還有鑄鐵，陶瓷類(lèi)，樹(shù)脂塑料。</p><p> 所以不會(huì)發(fā)生O型環(huán)的磨蝕引起的軸或軸套的磨損，從而起到保護(hù)泵走的作用適用于腐蝕性流體：只要選用耐腐蝕性高的哈氏合金276等材料制造焊接波紋管同樣避免了彈簧和O型環(huán)的腐蝕問(wèn)題，有效實(shí)現(xiàn)密封。不會(huì)發(fā)生懸掛泄漏：普通的推環(huán)式機(jī)械密封，泄漏出來(lái)的微量流體遇空氣會(huì)固化沉積，阻止O型動(dòng)環(huán)的前進(jìn)，使密封端面的貼合力變?nèi)趸蛳В瑥亩鴮?dǎo)致泄漏。相反焊接波紋管機(jī)械密封沒(méi)有O型環(huán)圈，即使有固化，影響也不大，仍可安穩(wěn)地旋轉(zhuǎn)，故適用壽命較長(zhǎng)。具有螺紋泵送作用：波紋管本身具有螺紋泵送作用，可有效對(duì)應(yīng)含固體顆粒的流體，并有助于沖洗。機(jī)械密封與填料密封對(duì)比：與填料密封相比，機(jī)械密封具有密封性能可靠、泄漏量小、壽命長(zhǎng)等優(yōu)點(diǎn)?？捎糜诟鞣N不同粘度、強(qiáng)腐蝕性和含顆粒的介質(zhì)。機(jī)械密封適用于輸送石油及化工介質(zhì)。但是機(jī)械密封價(jià)格貴，加工安裝維修保養(yǎng)比一般密封要求高。填料密封結(jié)構(gòu)簡(jiǎn)單、價(jià)格便宜、維修方便，但泄漏量大、功率損失大。因此，填料密封用于輸送一般介質(zhì)，如水；不適用于石油及化工介質(zhì)，特別是不能用在貴重、易爆和有毒介質(zhì)中。所以在機(jī)泵的運(yùn)行巡回檢查過(guò)程中對(duì)填料函的檢查是特別要注意。在運(yùn)行600個(gè)小時(shí)左右就要對(duì)填料進(jìn)行更換。無(wú)錫輕型機(jī)械密封件。</p><div
