普通油封的使用壓力一般不超過。當工作壓力超過這個值時應選用耐壓型油封。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)時為-40~120℃，亞力克橡膠(ACM)-30~180℃，氟橡膠(FPM)-25~300℃。七、對應軸及腔體的設計要求軸的設計：1、表面粗糙度，由于軸的速度與油量不同，一般軸的粗糙度過大或過小，都會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。當介質(zhì)較臟，有來自外界的污染雜質(zhì)，或軸表速度>12m/s時，軸表面硬度應為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精研磨，金剛砂紙磨光。不適宜的加工方法是在車床上精加工，超精加工，滾光加工，金剛砂紙磨光（砂紙在軸向移動磨光）。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，樹脂塑料。聊城機械密封件錫山區(qū)橡膠波紋管機械密封件。</p><div

以及機械密封的平衡程度，還有密封端面液膜的閃蒸等都是造成端面打開而使固體顆粒進入的主要原因。c）機械密封的平衡程度β也影響著密封的磨損。一般情況下，平衡程度β=75%左右適宜。β<75%，磨損量雖然降低，但泄漏增加，密封面打開的可能性增大。對于高負荷（高PV值）的機械密封，由于端面摩擦熱較大，β一般取65%～70%為宜，對低沸點的烴類介質(zhì)等，由于溫度對介質(zhì)氣化較敏感，為減少摩擦熱的影響，β取80%～85%為好。7.因安裝、運轉(zhuǎn)或設備本身所產(chǎn)生的誤差而造成機械密封泄漏a）由于安裝不良，造成機械密封泄漏。主要表現(xiàn)在以下幾方面：1）動、靜環(huán)接觸表面不平，安裝時碰傷、損壞；2）動、靜環(huán)密封圈尺寸有誤、損壞或未被壓緊；3）動、靜環(huán)表面有異物；4）動、靜環(huán)V型密封圈方向裝反，或安裝時反邊；5）軸套處泄漏，密封圈未裝或壓緊力不夠；6）彈簧力不均勻，單彈簧不垂直，多彈簧長短不一；7）密封腔端面與軸垂直度不夠；8）軸套上密封圈活動處有腐蝕點。b）設備在運轉(zhuǎn)中，機械密封發(fā)生泄漏的原因主要有：1）泵葉輪軸向竄動量超過標準，轉(zhuǎn)軸發(fā)生周期性振動及工藝操作不穩(wěn)定，密封腔內(nèi)壓力經(jīng)常變化等均會導致密封周期性泄漏。</p><p> 特別要注意彈簧的旋向，其旋向應與軸轉(zhuǎn)動方向相同，使彈簧越旋越緊，就是按定出的軸旋轉(zhuǎn)方向，從靜環(huán)朝動環(huán)方向看，順時針方向需要右旋彈簧，逆時針方向則要左旋彈簧.使用小彈簧時，要檢查各組彈簧的圈數(shù)和自由高度;6.對安裝機械密封的主機按技術(shù)要求檢查軸向串量、徑向跳動、有關(guān)的垂直度、同心度、表面粗糙度、配合尺寸和對泵的聯(lián)軸節(jié)要求等.(1)軸向串量:要求不超過，一般在，軸向串量過大，使機械密封彈簧比壓不穩(wěn)定，引起密封端面過全磨損或泄漏，由于軸的抖動而使密封破損，這在石墨環(huán)更為明顯二此外，因軸向串童過大，還會使機械密封與軸(或軸套)的接觸處局部腐蝕、侵蝕或磨損，在這方面，聚四氛乙烯密封圈因彈性不及橡膠密封圈，其所受影響更大.因此，軸向串量從原要求±，可以減輕因軸向串量過大而引起的危害，另一方面，如軸向串量過小，如低于m時，則對軸承產(chǎn)生不良影響.實際上，軸向串全還與軸的轉(zhuǎn)速有關(guān)，圖9-1是軸向串量允許值與轉(zhuǎn)速關(guān)系，可供安裝時參考。聯(lián)軸節(jié)對中要求的檢查應該在所有管線接頭安裝以后進行，否則找正工作就不徹底。關(guān)于兩個半聯(lián)軸節(jié)連接后端面間的間晾，可參照有關(guān)規(guī)定，一般端面間隙略大于軸向串量。因為聯(lián)軸節(jié)的種類很多。南通109-20機械密封件。</p><div

以防突然啟動而造成軟環(huán)破裂.2.正常使用前先進行常琢運轉(zhuǎn)，觀察密封部位的溫升是否正常.如有輕徽泄漏，可跑合一段時間，使端面貼合更加均勻，直到泄漏童逐漸減少至正常為止.如運轉(zhuǎn)1~3小時泄漏量仍不減少，則需停車檢查.3.升壓、升溫運轉(zhuǎn):經(jīng)過常壓運轉(zhuǎn)考驗的機械密封應及時做與操作條件相同的升壓、升溫運轉(zhuǎn).升壓、升溫可分別進行.升的過程應緩慢，注意升壓(或升溫)過程中可能發(fā)生的變化，如機件有無碰撞，端面是否脫開，摩擦發(fā)熱是否過快，防轉(zhuǎn)銷有無脫開或損壞，壓力是否穩(wěn)定(要求壓力波動不大于±)以及密封圈處和密封端面處有無泄漏等，如果一切正常，即可投人生產(chǎn)。機械密封故障的產(chǎn)生原因及處理措施一、機械密封故降的產(chǎn)生原因機械密封故障的產(chǎn)生原因主要有以下幾個方面:1.機械密封本身不良造成的故障;2.主機問題造成的故障;3.機械密封的選擇和應用不當所造成的故障;4.安裝和操作不當以及管理不善所造成的故障;5.輔助裝置不良或?qū)o助裝置認識不夠造成的故障.機械密封的故障現(xiàn)象有:端面磨損、密封環(huán)熱裂、變形、腐蝕、彈贊失去彈性或折斷、輔助密封圈損壞等.國外有人對三百套機械密封在五年間所發(fā)生的故障進行統(tǒng)計分析，其結(jié)果如表9-4所示。由表9-4可見。江陰109-50機械密封件。聊城機械密封件</p><p
