但密封效果較差。2、曲折式迷宮密封曲折式迷宮密封也分整體和鑲片兩種結(jié)構(gòu)，這種迷宮密封的結(jié)構(gòu)特點，是密封齒的伸出高度不一樣，而且高低齒相間排列，與之相配的軸表面，是特制的凹凸溝槽，這種高低齒與凹凸槽相配合的結(jié)構(gòu)，使平滑的密封間隙變成了曲折式，因此，增加了流動阻力，提高了密封效能。但只能用在有水平剖分面的缸體或隔板中，并且密封體也要作成水平剖分型。3、階梯式迷宮密封階梯式迷宮密封從結(jié)構(gòu)上分析它類似于平滑式迷宮密封，而密封效果卻與曲折式迷宮密封近似，常用于葉輪蓋板和平衡盤處。4、蜂窩式迷宮密封蜂窩式迷宮密封的密封齒片焊成蜂窩狀，以形成復(fù)雜形狀的膨脹室，它的密封性能優(yōu)于一般密封形式，適用于壓力差較大的場合，如離心式壓縮機的平衡盤密封。蜂窩式迷宮密封制造工藝復(fù)雜，密封片強度高，密封效果較好。五，撫州神通博格曼機械密封件DTM、油封密封油封密封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，撫州神通博格曼機械密封件DTM，成本低廉，維護方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對磨損有一定的補償能力，但不耐高壓，撫州神通博格曼機械密封件DTM，所以一般用在低壓場合的化工泵上。六、動力密封化工泵在與運轉(zhuǎn)時，副葉輪所產(chǎn)生的壓頭平衡了主葉輪出口高壓液體，從而實現(xiàn)密封。湖北神通博格曼機械密封件。撫州神通博格曼機械密封件DTM</p><div

三是安裝、拆卸困難，極易損壞靜環(huán)。誤區(qū)四：葉輪鎖母越緊越好？！機械密封泄漏中，軸套與軸之間的泄漏(軸間泄漏)是比較常見的。一般認(rèn)為，軸間泄漏就是葉輪鎖母沒鎖緊，其實導(dǎo)致軸間泄漏的因素較多，如軸間墊失效，偏移，軸間內(nèi)有雜質(zhì)，軸與軸套配合處有較大的形位誤差，接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長等都會導(dǎo)致軸間泄漏。鎖母鎖緊過度只會導(dǎo)致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運轉(zhuǎn)中鎖母會自動適時鎖緊，使軸間始終處于良好的密封狀態(tài)。誤區(qū)五：新的比舊的好？！相對而言，使用新機械密封的效果好于舊的，但新機械密封的質(zhì)量或材質(zhì)選擇不當(dāng)時，配合尺寸誤差較大會影響密封效果；在聚合性和滲透性介質(zhì)中，靜環(huán)如無過度磨損，還是不更換為好。因為靜環(huán)在靜環(huán)座中長時間處于靜止?fàn)顟B(tài)，使聚合物和雜質(zhì)沉積為一體，起到了較好的密封作用。誤區(qū)六：拆修總比不拆好？！一旦出現(xiàn)機械密封泄漏便急于拆修，其實，有時密封并沒有損壞，只需調(diào)整工況或適當(dāng)調(diào)整密封就可消除泄漏。這樣既避免浪費又可以驗證自己的故障判斷能力，積累維修經(jīng)驗提高檢修質(zhì)量。撫州神通博格曼機械密封件204B河南神通博格曼機械密封件。</p><div

4.使用環(huán)節(jié)中的漏油現(xiàn)象1）壓力造成滲漏。使用中當(dāng)密封腔內(nèi)壓力>3MPa時，可能導(dǎo)致端面比壓過大，液膜難以成，密封端面磨損嚴(yán)重，發(fā)熱量增多，造成密封面熱變形。而泵在啟動、停機過程中，由于泵進口堵塞，抽送介質(zhì)中含有氣體等原因，可能使密封腔出現(xiàn)負(fù)壓，繼而引起密封端面干摩擦，內(nèi)裝式機械密封會產(chǎn)生漏油現(xiàn)象。2）介質(zhì)問題。首先，由于密封圈等輔助元件常采用不耐酸堿和高溫的有機材料，當(dāng)介質(zhì)中含有弱酸、弱堿時，長期的使用會使其失去彈性甚至腐爛；而介質(zhì)中出現(xiàn)固體顆粒等物質(zhì)時，也會劃傷端面造成磨損，同時油垢、油污等也可能在軸表面造成堆積。此外，油溫超標(biāo)也是導(dǎo)致機械密封性能下降的主要原因，因此當(dāng)熱交換器的冷卻能力不足時，密封的使用壽命常會**縮短。3）旋動環(huán)和靜止環(huán)疲勞損壞。給油泵軸線不一致或者軸承間隙調(diào)整不當(dāng)都會引起給油泵的振動，而振動會導(dǎo)致機械密封組件中的動靜部分發(fā)生摩擦，即使其接觸面的油膜發(fā)生破壞，導(dǎo)致其失去油膜潤滑而損壞。4）生產(chǎn)管理缺失。機組工作中未按操作規(guī)程進行，開停機不當(dāng)或人為操作錯誤導(dǎo)致供電波動使油泵倒轉(zhuǎn)等都可能引起密封發(fā)生泄漏。5）缺油運行造成干磨損壞。這種現(xiàn)象多見于底閥式安裝形式進口處負(fù)壓。撫州神通博格曼機械密封件DTM</p><p
