用于壓縮機的高速機械密封的直徑較大，而用于高速泵的機械密封尺寸一般都在2in左右.高速泵用的機械密封以美國約翰克蘭公司(JohnCranePackingCompany)的9AB型密封為典型[圖10-17(a),(b)]，這種密封常用在美國Sundstrand公司高速泵的齒輪箱和泵體的密封上.為了節(jié)省空間并獲得較高的重量與功率比，無論泵的結(jié)構(gòu)和機械密封結(jié)構(gòu)都很緊湊，一般石油化工公司都引進這種高速泵‘，目前揚子石油化工公司有關(guān)裝置使用51臺(見表3-41)，中國石油化工總公司系統(tǒng)使用近200臺。圖中60C用于齒輪箱密封，60A或60A+60B用于泵葉輪端密封.低溫機械密封一般低溫機械密封是指工作溫度在0~-50℃的密封，API-610的低溫含義指溫度低于-29℃，國內(nèi)通常以密封腔溫度低于-20℃為低溫.實際上，低溫范圍較寬，可以劃分為:低溫:-20~-50℃中低溫:-50~-100℃極低溫:-100~-196℃**溫:<-196℃泵送低溫介質(zhì)主要指液化氣體和易揮發(fā)的液體，如液態(tài)氮、液態(tài)氧、甲烷、乙烷、乙烯等液化氣。關(guān)于氮、氧、空氣等液化氣體的物理性能如表10-3所示.關(guān)于乙烯、丙烯、甲烷、乙烷、丙烷的物理性能如圖10-18(a)、(b)、(c)，安慶FMY212釜用機械密封件，安慶FMY212釜用機械密封件、(d)所示·一，安慶FMY212釜用機械密封件、低溫機械密封的要求1.材料要求金屬材料隨著溫度降低。廈門MR-D釜用機械密封件。安慶FMY212釜用機械密封件</p><div

***節(jié)機械密封原理機械密封是一種旋轉(zhuǎn)機械的軸封裝置。比如離心泵、離心機、反應(yīng)釜和壓縮機等設(shè)備。由于傳動軸貫穿在設(shè)備內(nèi)外，這樣，軸與設(shè)備之間存在一個圓周間隙，設(shè)備中的介質(zhì)通過該間隙向外泄漏，如果設(shè)備內(nèi)壓力低于大氣壓，則空氣向設(shè)備內(nèi)泄漏，因此必須有一個阻止泄漏的軸封裝置。軸封的種類很多，由于機械密封具有泄漏量少和壽命長等優(yōu)點，所以當(dāng)今世界上機械密封是這些設(shè)備主要的軸密封方式。機械密封又叫端面密封，在國家有關(guān)標準中是這樣定義的：“由至少一對垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補償機構(gòu)彈力（或磁力）的作用以及輔助密封的配合下保持貼合并相對滑動而構(gòu)成的防止流體泄漏的裝置?！币?、機械密封的分類機械密封近年來發(fā)展很快，根據(jù)不同的工況出現(xiàn)了各種各樣的結(jié)構(gòu)，但無論哪種結(jié)構(gòu)都由以下四部分組成：一部分是由動環(huán)和靜環(huán)組成的密封端面，有時也稱為摩擦副。第二部分是由彈性元件為主要零件組成的緩沖補償機構(gòu)，其作用是使密封端面緊密貼合。第三部分是輔助密封圈，其中有動環(huán)和靜環(huán)密封圈。第四部分是使動環(huán)隨軸旋轉(zhuǎn)的傳動機構(gòu)。機械密封實現(xiàn)的原理如圖所示：軸通過傳動座（6）和推環(huán)（4），帶動動環(huán)（2）旋轉(zhuǎn)，靜環(huán)(1)固定不動。太原搪玻璃釜用機械密封德州M481釜用機械密封件。</p><div

還與軸徑尺寸有關(guān).當(dāng)摩擦副環(huán)基體為不銹鋼、高鎳合金、欽合金時，熱鑲硬質(zhì)合金的允許使用溫度對不同軸徑的關(guān)系如圖10-9所示.5.摩擦副環(huán)與軸之間的許用間隙高溫條件下，由于摩擦副環(huán)與軸兩者的熱脹系數(shù)的差異，會出現(xiàn)摩擦副環(huán)與軸之間間隙趨近于零的現(xiàn)象，因而造成摩擦副環(huán)浮動性消失導(dǎo)致密封失效。所以在設(shè)計時必須合理和正確選擇摩擦副環(huán)與軸之間的間隙。二、高溫機械密封實例1.布格曼公司的HSHF+MFL型密封芳烴裝置循環(huán)油泵GA-102AB.功率1650kW，轉(zhuǎn)速6748r/min,輸送介質(zhì)為汽油，操作溫度262~284度，進口壓力，出口壓力~175MPa，機械密封采用布格曼公司HSHF+MFL混合結(jié)構(gòu)，這是適合高溫、高壓和高速工作條件下的密封。這里HSHF是單端面、流體動壓式帶泵效螺旋結(jié)構(gòu)MFL是單端面金屬波紋管結(jié)構(gòu).HSHF和MFL都是彈簧靜止式，以適應(yīng)高速運轉(zhuǎn)的要求.該密封從結(jié)構(gòu)上布置成串聯(lián)式，裝于油泵的吸人端和排出端，因HSHF帶有泵效螺旋，它與軸的旋轉(zhuǎn)方向有關(guān).在吸入端的泵效套(12A)是右螺旋，泵效外殼(25A)提左螺旋;在排出端的泵效套(12B)是左螺旋，泵效外殼(25B)是右螺旋，安裝時按圖上要求裝配不能搞錯.，圖10-10為HSHF2/103+MFL65/88的結(jié)構(gòu)圖.。</p><p> 這兩套密封與旋轉(zhuǎn)方向有關(guān)，進出口端不能裝錯，泵效套也不能互換。高速機械密封當(dāng)線速度超過25~30m/s時，可視為高速，有的密封公司把滑動面速度高達33m/s，才作為高速機械密封.’我國ZBJ22-001-88規(guī)定密封端面平均線速度為25~100m/s時為高速機械密封，密封端面平均線速度大于100m/S時為超高速機械密封.在高速時，由于離心力的影響，造成振動和不平衡度，高速如同高壓一樣，產(chǎn)生熱變形、熱應(yīng)力裂紋及磨損物、沉淀物引起泄漏損失，而且這種損失將隨滑動速度的增加而強烈地增加.一、高速機械密封的要求1.減少轉(zhuǎn)動件的重量(質(zhì)量)，提高動力平衡度高速時，離心力的影響使彈簧扭曲和偏離銷孔中心，因此，彈簧必須是靜止式。這樣減少了轉(zhuǎn)動件的重量及由此造成的不平衡度。2.及時排除摩擦熱加大冷卻介質(zhì)的流量，高速泵為10~20L/min，有的高速密封的沖洗量達50~100L/min。用油作阻封液時，為了使氣體的溶解度和結(jié)焦盡量小，應(yīng)選用粘度低的油。如摩擦副處于高溫條件下工作時，要盡一切可能使密封液在蒸發(fā)時不留殘渣，所以使用聚乙二醇這類合成介質(zhì)作阻封液，3.及時檢查滑動端面磨損量當(dāng)端面磨損量達到，就要對端面進行研磨，并重新檢查端面粗糙度和平直度。二、9AB型高速泵機械密封。鶴壁2009釜用機械密封件。</p><div

依靠介質(zhì)壓力和彈簧力使動靜環(huán)之間的密封端面緊密貼合，阻止了介質(zhì)的泄漏。摩擦副表面磨損后，在彈簧（5）的推動下實現(xiàn)補償。為了防止介質(zhì)通過動環(huán)與軸之間泄漏，裝有動環(huán)密封圈（3）；而靜環(huán)密封圈（7）則阻止了介質(zhì)沿靜環(huán)和壓蓋（8）之間的泄漏。長期的實踐證明，輔助設(shè)施的作用不可忽視。從國外進來的泵，在提供的機械密封圖紙上，不僅有密封結(jié)構(gòu)圖，而且在這張圖上明確地畫出了輔助設(shè)施的安裝圖，并注明輔助設(shè)施的種類和數(shù)量。國內(nèi)的制造廠有的開始注意這個問題；有的還沒認識，這是不應(yīng)該的。輔助設(shè)施不僅起冷卻和潤滑作用，還可改善密封的工作環(huán)境，從而減少泄漏量和延長使用壽命。因此有人把輔助設(shè)施看作是機械密封的組成部分。無疑，這一觀點將被越來越多的人接受。機械密封被***地應(yīng)用于各種旋轉(zhuǎn)機械的軸封，工況不同，使用的密封也不同。機械密封按使用條件可分為高速和普通機械密封；高壓和低壓機械密封；高溫、常溫和低溫機械密封；泵用、壓縮機用和釜用機械密封以及耐腐蝕機械密封和抗顆粒的機械密封等。通常都按機械密封的結(jié)構(gòu)和原理來分類，例如旋轉(zhuǎn)式和靜止式機械密封；內(nèi)流式和外流式機械密封；平衡型和非平衡型機械密封等。威海M461釜用機械密封件。昌平區(qū)加氯釜用機械密封</p><p

密封液壓力平衡系統(tǒng)的壓力源由氮氣瓶提供。密封腔壓力固定控制在比釜內(nèi)壓力高。為了適應(yīng)釜內(nèi)壓力的變化，機械密封下端面也應(yīng)采用平衡型結(jié)構(gòu)。四、液壓泵站密封液循環(huán)系統(tǒng)液壓泵站密封液循環(huán)系統(tǒng)與釜用機械密封組合型式見圖1一17。在高負荷的密封裝置中，應(yīng)采用液壓泵站密封液循環(huán)系統(tǒng)來強制密封液的冷卻循環(huán)。液壓泵站中密封液的壓力源由離心泵、齒輪泵或柱塞泵等提供。利用泵送壓力強迫密封液在密封腔內(nèi)循環(huán)。該系統(tǒng)還應(yīng)配合過濾器、冷卻器、儲能器、調(diào)節(jié)閥、壓力表等使用。調(diào)節(jié)好閥的壓力，使密封腔的壓力大于釜內(nèi)壓力。使用液壓泵站密封液循環(huán)系統(tǒng)的雙端面機械密封，下端面也必須采用平衡型結(jié)構(gòu)。除此之外，還有手壓泵增壓系統(tǒng)等型式。只有合理選用輔助系統(tǒng)，才能保證雙端面密封的使用。安慶FMY212釜用機械密封件</p><p
