隨著水泵工作狀態(tài)時刻變化和工作周期的增長，填料的磨損程度逐漸加大，即填料與軸的間隙越來越大，從而導(dǎo)致軟填料密封的泄漏增加，因此總是通過人工調(diào)節(jié)壓蓋螺栓來調(diào)節(jié)填料的預(yù)緊力。為了增大軟填料密封的壽命，經(jīng)過仔細的實驗研究得出如下三種改進方法：種就是將金屬環(huán)，軟填料環(huán)，圓柱形彈簧交替組合安裝，通過分別調(diào)節(jié)各層軟填料環(huán)的壓縮力，從而得到佳的徑向應(yīng)力分布。為此在制作填料時往往需要浸漬填充各種潤滑劑和填充劑第二種是將一組軟填料環(huán)安裝在一個可以軸向移動的金屬套筒中，將圓柱形彈簧安裝在壓蓋螺栓內(nèi)，通過調(diào)節(jié)壓蓋螺栓來調(diào)節(jié)預(yù)緊力。第三種是將金屬環(huán)和填料環(huán)做成不同規(guī)格，使金屬環(huán)和軟填料沿填料涵底方向逐漸減小，從而在壓蓋的作用力下，軟填料的徑向應(yīng)力相應(yīng)逐漸增加，使得徑向應(yīng)力獲得合理分布。②關(guān)于軟填料環(huán)的圈數(shù)設(shè)計問題，一般其圈數(shù)在至圈為宜。③軟填料的材質(zhì)選擇問題，其原則是：一是有一定的彈塑性，當水泵填料受軸向壓緊時能有一定的補償能力追隨性;二是有一定的強度，使水泵填料不至于在未磨損前先損壞;三是化學(xué)穩(wěn)定性高，不被流體介質(zhì)腐蝕和溶脹，同時也不污染介質(zhì);四是不滲透性好，對填料的組織結(jié)構(gòu)致密性要求高。江蘇CLS40959-733231格蘭富機械密封件漳州格蘭富機械密封件。</p><div

依賴輔助密封的配合與另一端保持貼合，并相對滑動，從而防止流體泄漏。四、機械密封常用材料的選用清水，常溫：（動）9Cr18，1Cr13堆焊鈷鉻鎢，鑄鐵；（靜）浸樹脂石墨，青銅，酚醛塑料。河水（含泥沙），常溫：（動）碳化鎢，（靜）碳化鎢。海水，常溫：（動）碳化鎢，1Cr13堆焊鈷鉻鎢，鑄鐵；（靜）浸樹脂石墨，碳化鎢，金屬陶瓷。過熱水100度：（動）碳化鎢，1Cr13堆焊鈷鉻鎢，鑄鐵；（靜）浸樹脂石墨，碳化鎢，金屬陶瓷。汽油，潤滑油，液態(tài)烴，常溫：（動）碳化鎢，1Cr13堆焊鈷鉻鎢，鑄鐵；（靜）浸樹脂或錫銻合金石墨，酚醛塑料。汽油，潤滑油，液態(tài)烴，100度：（動）碳化鎢，1Cr13堆焊鈷鉻鎢；（靜）浸青銅或樹脂石墨。汽油，潤滑油，液態(tài)烴，含顆粒：（動）碳化鎢；（靜）碳化鎢。五、密封材料的種類及用途密封材料應(yīng)滿足密封功能的要求。由于被密封的介質(zhì)不同，以及設(shè)備的工作條件不同，要求密封材料的具有不同的適應(yīng)性。對密封材料的要求一般是：1）材料致密性好，不易泄露介質(zhì)。2）有適當?shù)臋C械強度和硬度。3）壓縮性和回彈性好，變形小。4）高溫下不軟化，不分解，低溫下不硬化，不脆裂。5）抗腐蝕性能好，在酸，堿，油等介質(zhì)中能長期工作。</p><p> 動環(huán)和靜環(huán)的端面組成一對摩擦副，動環(huán)靠密封室中液體的壓力使其端面壓緊在靜環(huán)端面上，并在兩環(huán)端面上產(chǎn)生適當?shù)谋葔汉捅３忠粚訕O薄的液體膜而達到密封的目的。壓緊元件產(chǎn)生壓力，可使泵在不運轉(zhuǎn)狀態(tài)下，也保持端面貼合，保證密封介質(zhì)不外漏，并防止雜質(zhì)進入密封端面。密封圈起密封動環(huán)與軸的間隙、靜環(huán)與壓蓋的間隙的作用，同時對泵的振動、沖擊起緩沖作用。機械密封在實際運行中不是一個孤立的部件，它是與泵的其它零部件一起組合起來運行的。三、機械密封的輔助設(shè)施—沖洗裝置沖洗裝置是機械密封主要的輔助設(shè)施，泵在運轉(zhuǎn)過程中，密封腔中沉積或形成雜質(zhì)，必須進行沖洗。否則會因結(jié)晶的析出、顆粒雜質(zhì)的沉淀，使機械密封動、靜環(huán)失去浮動性，彈簧失靈。更嚴重的是顆粒磨損、雜質(zhì)進入摩擦副會加劇磨損，導(dǎo)致機械密封迅速失效。所以，一般情況下泵用機械密封均應(yīng)進行沖洗。四、機械密封泄漏的原因分析新安裝(或更換)的機械密封投入運轉(zhuǎn)時泄漏量應(yīng)在允許范圍內(nèi)。如果密封本身的結(jié)構(gòu)、制造質(zhì)量、安裝和使用等方面都無問題，其壽命要超過8000h。實際工作中，不少密封的使用壽命遠沒有達到該值前就失效了，這是由于工藝條件、設(shè)備運行狀況和操作存在一定的問題造成的。昌平區(qū)格蘭富機械密封件。</p><div
