機(jī)械密封用于各種類型的泵。機(jī)械密封是一種精度較高的密封裝置，對(duì)安裝和使用條件均有一定的要求。1、機(jī)械密封安裝使用的一般原則(1)弄清設(shè)備的情況，要了解設(shè)備轉(zhuǎn)軸的轉(zhuǎn)速、軸徑;設(shè)備制造精度及密封腔尺寸，設(shè)備本身的使用壽命以及設(shè)備在生產(chǎn)工藝中的地位等要做***均衡的考慮。(2)估算介質(zhì)壓力。泵的密封腔壓力一般不是泵的出口壓力，而是低于泵的出口壓力。(3)弄清密封介質(zhì)情況。要知道密封介質(zhì)的狀態(tài)，是氣態(tài)還是液態(tài)，介質(zhì)是否含顆粒及顆粒狀況;了解介質(zhì)的性質(zhì)、溫度，以便合理選型及采取必要的冷卻、沖洗、潤(rùn)滑措施。2、機(jī)械密封安裝使用的技術(shù)要求(1)安裝機(jī)械密封部位的軸或軸套的徑向跳動(dòng)公差：Ф10~50mmФ50~120mm,。軸或軸套的表面粗糙度應(yīng)符合技術(shù)要求，外徑尺寸公差為h6。(2)傳動(dòng)軸的軸向竄動(dòng)量不超過。(3)密封腔體端面對(duì)軸表面的跳動(dòng)公差：軸或軸套外徑端面跳動(dòng)公差:Ф10~50mm，Ф50~120mm,(4)軸或軸套的端面及密封腔體的端面要有倒角。軸徑≤Φ30mm時(shí)為3×10°，軸徑>Φ30mm時(shí)為4×10°。(5)當(dāng)輸送介質(zhì)溫度偏高、過低或含有雜質(zhì)顆粒、易燃、易爆、有毒時(shí)，應(yīng)采取相應(yīng)的阻封、沖洗、冷卻、過濾等措施。(6)對(duì)某些靠彈簧傳動(dòng)的機(jī)械密封必須注意彈簧的旋向。哈爾濱502神通博格曼機(jī)械密封502神通博格曼機(jī)械密封。</p><div

泵用機(jī)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(huì)影響密封性能，要正確安裝必須注意以下幾點(diǎn)：一、泵用機(jī)械密封的冷卻和沖洗1、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。2、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(shí)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(qiáng)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(shí)。再進(jìn)入密封腔冷卻沖洗，該形式是冷卻效果良好的一種。3、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)。二、泵用機(jī)械密封的安裝和技術(shù)要求1、對(duì)機(jī)、泵以及機(jī)械密封的配合部分技術(shù)要求：a.軸彎曲度不得超過。b.部件內(nèi)各零件均符合圖紙要求。上緊壓蓋時(shí)應(yīng)在聯(lián)軸器找正后進(jìn)行，壓緊螺絲應(yīng)均上緊，防止法蘭面偏斜。c.彈簧的壓縮量按圖紙規(guī)定進(jìn)行允許誤差±2mm。軸在安裝機(jī)械密封處的振擺量不得大于。軸的軸向竄動(dòng)量不允許大于。綏化神通博格曼機(jī)械密封。</p><div

一、汽輪機(jī)組輔機(jī)泵1、鍋爐給水泵由于鍋爐給水泵揚(yáng)程很高，高達(dá)百米以上(大型給水泵可達(dá)千米)，因而機(jī)械密封的應(yīng)力很大，在高壓高速水流沖刷下若仍采用普通的不銹鋼，浸蝕將非常嚴(yán)重，故機(jī)械密封要選用抗蝕、抗沖刷和機(jī)械性能良好的材料，如基礎(chǔ)框架采用316或316L精加工而成。摩擦副采用Tc/Tc，這種節(jié)段式泵的泵體結(jié)構(gòu)簡(jiǎn)單，但拆裝麻煩，檢修時(shí)間長(zhǎng)，另外因?yàn)檠剌S線水流對(duì)泵體四周的加熱不易均勻，所以需要較長(zhǎng)的暖泵啟動(dòng)時(shí)間。所用的機(jī)械密封要求壽命時(shí)間長(zhǎng)，對(duì)介質(zhì)溫度變化要求有適當(dāng)?shù)倪m應(yīng)能力。主要注意的泵的汽蝕機(jī)械密封的影響。前置給水泵的轉(zhuǎn)速較高，為解決汽蝕問題一般都采用前置給水泵，以提高主給水泵進(jìn)口壓力。前置給水泵密封形式和鍋爐給水泵的密封形式類似，都要考慮汽蝕對(duì)機(jī)械密封的影響。2、循環(huán)水泵循環(huán)水泵的功用是向汽輪機(jī)的凝汽器、冷油器和發(fā)電機(jī)的空氣(氫氣、水)冷卻器等供應(yīng)冷卻水。發(fā)電廠冷卻水用量很大，但壓力一般不高，因此，對(duì)循環(huán)水泵的要求是大流量、低揚(yáng)程，所用機(jī)械密封輔助常采用氟醚橡膠或硅橡膠。3、凝結(jié)水泵從結(jié)構(gòu)上可以分為臥式、立式以及立式筒袋式多級(jí)凝結(jié)水泵。臥式凝結(jié)水泵適用于小容量機(jī)組。福州神通博格曼機(jī)械密封。哈爾濱502神通博格曼機(jī)械密封</p><p
