輔助密封圈是機(jī)械密封上**薄弱環(huán)節(jié)，當(dāng)溫度超過(guò)80℃時(shí)普通橡膠已不適用，溫度超過(guò)230~250℃，長(zhǎng)春泵用機(jī)械密封型號(hào)，聚四氟乙烯也不能使用.此外，由于高溫、易燃介質(zhì)的裂解物沉積會(huì)使彈簧阻塞.所以，當(dāng)溫度超過(guò)220℃時(shí)就應(yīng)采用金屬波紋管型機(jī)械密封，或者采用金屬波紋管與普通機(jī)械密封相結(jié)合的密封結(jié)構(gòu).3.采取冷卻措施在高溫下，為了使密封可靠運(yùn)行，盡可能對(duì)機(jī)械密封進(jìn)行冷卻，要避免在干摩擦狀態(tài)下工作.必須保持密封間隙中的溫度在密封液的汽化溫度以下.冷卻措施就是對(duì)密封進(jìn)行溫度控制，常用的溫度控制有沖洗、阻封、加強(qiáng)液體循環(huán)等(詳見(jiàn)第七章***節(jié)溫度控制裝置)。在高溫下，還可采用以下措施:(1)用Diphy1(二苯及二苯氧化物的混合物)作為阻封液，它是冷態(tài)無(wú)壓的換熱劑(阻封液由泵效螺旋輸送);(2)在超高溫下或者沒(méi)有適當(dāng)?shù)囊后w時(shí)，也可通人氮?dú)?、氬氣，以防止空氣引起的氧化，長(zhǎng)春泵用機(jī)械密封型號(hào).4.鑲嵌摩擦副問(wèn)題密封環(huán)鑲嵌是充分利用端面材料和基體材料的特性，提高材料使用價(jià)值，長(zhǎng)春泵用機(jī)械密封型號(hào)，一般對(duì)高溫密封采用熱鑲法.但是，由于端面耐磨材料和基體材料的熱脹系數(shù)有差異，在高溫下使用時(shí)會(huì)產(chǎn)生摩擦環(huán)松動(dòng)、脫落。因此，對(duì)鑲嵌結(jié)構(gòu)的摩擦環(huán)采用的溫度應(yīng)予以特別注意.熱鑲結(jié)構(gòu)產(chǎn)生松動(dòng)、脫落的原因，除了與使用溫度有關(guān)外。延安化工泵用機(jī)械密封選型。長(zhǎng)春泵用機(jī)械密封型號(hào)</p><div

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)式機(jī)械密封傳動(dòng)座和動(dòng)環(huán)的傳動(dòng)方式1）銷(xiāo)釘傳動(dòng)。通過(guò)推環(huán)，在推環(huán)和動(dòng)環(huán)之間用銷(xiāo)釘實(shí)現(xiàn)傳動(dòng)（圖35），這種傳動(dòng)方式多用在小彈簧的結(jié)構(gòu)上。2）突耳傳動(dòng)。國(guó)內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。在動(dòng)環(huán)外緣制成圓弧槽，而將與此接觸的傳動(dòng)座壓成突耳，使之嵌入動(dòng)環(huán)的槽中，實(shí)現(xiàn)傳動(dòng)（圖13）。這種結(jié)構(gòu)可用于大彈簧，也可用于小彈簧的密封結(jié)構(gòu)。3）并圈彈簧傳動(dòng)。傳動(dòng)座與彈簧以及彈簧和動(dòng)環(huán)之間，完全依靠大彈簧內(nèi)徑的過(guò)盈值實(shí)現(xiàn)傳動(dòng)（圖34），當(dāng)然也有旋向的要求。這種結(jié)構(gòu)都用在大彈簧的密封結(jié)構(gòu)上。4）勾圈彈簧傳動(dòng)。為了增加并圈彈簧傳動(dòng)的可靠性，彈簧的兩個(gè)端頭制成彎勾形，分別鉤住傳動(dòng)座和動(dòng)環(huán)（圖36）。5）離合器傳動(dòng)。傳動(dòng)座和動(dòng)環(huán)（或通過(guò)推環(huán)）分別制成方形的凸起和缺口，組裝好后凸起插入缺口中實(shí)現(xiàn)傳動(dòng)（圖37）。6）波紋管傳動(dòng)。這種方式是波紋管型密封的特有結(jié)構(gòu)，波紋管兩端分別與傳動(dòng)座和動(dòng)環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定。例如，對(duì)金屬波紋管，則采用焊接；對(duì)于橡膠和四氟波紋管，則采用整體或其他方式聯(lián)接。靜止式機(jī)械密封的動(dòng)環(huán)的旋轉(zhuǎn)靜止式機(jī)械密封的動(dòng)環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。</p><p> 石油化工流程泵大都選用內(nèi)流型機(jī)械密封，只有在壓力和溫度不高的腐蝕性介質(zhì)中才選用外流型機(jī)械密封。按補(bǔ)償機(jī)構(gòu)中彈簧的數(shù)量可分為多彈簧和單彈簧機(jī)械密封。補(bǔ)償機(jī)構(gòu)中有多個(gè)彈簧的密封稱(chēng)為多彈簧機(jī)械密封（圖5）；補(bǔ)償機(jī)構(gòu)中只有一個(gè)彈簧的機(jī)械密封稱(chēng)為單彈簧機(jī)械密封（圖6），多彈簧機(jī)械密封又稱(chēng)小彈簧機(jī)械密封，這種結(jié)構(gòu)軸向尺寸較小，可用改變彈簧數(shù)量的方法改變彈性力，軸向力較均勻，適用于高速機(jī)械密封，在腐蝕性介質(zhì)中不宜采用。單彈簧機(jī)械密封又稱(chēng)大彈簧機(jī)械密封，密封結(jié)構(gòu)較為簡(jiǎn)單。有的密封型式還用彈簧傳遞扭矩。國(guó)產(chǎn)密封應(yīng)用大彈簧較多，但不能用于高速。圖5多彈簧機(jī)械密封圖6單彈簧機(jī)械密封補(bǔ)償機(jī)構(gòu)的作用是使密封端面緊密貼合，為達(dá)到此目的，采用的方法有兩種，一是彈性力，二是磁力。只有在系統(tǒng)內(nèi)壓力較低時(shí)采用磁力機(jī)械密封（圖7），大多數(shù)都用前者。除了用彈簧形成彈性力外還有用波紋管的，稱(chēng)為波紋管式機(jī)械密封。波紋管的材料可用橡膠、聚四氟乙烯和焊接的金屬薄片（圖8）等。（圖8）根據(jù)密封面上介質(zhì)載荷的作用情況可分為平衡型和非平衡型密封（圖9）。非平衡型：載荷系數(shù)k≥1的密封稱(chēng)為非平衡型密封，換言之。北京格蘭富泵用機(jī)械密封型號(hào)。</p><div

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。長(zhǎng)春泵用機(jī)械密封型號(hào)</p><p
