機(jī)械密封常見(jiàn)的損壞形式主要有腐蝕損壞、熱損壞和機(jī)械損壞。其中腐蝕損壞危害性較大，由于機(jī)械密封特殊的結(jié)構(gòu)形式及工作環(huán)境和條件不同，腐蝕損壞的形態(tài)也多種多樣。一．金屬環(huán)腐蝕1，表面均勻腐蝕。如果金屬環(huán)表面接觸腐蝕介質(zhì)，而金屬本身又不耐腐蝕，就會(huì)產(chǎn)生表面腐蝕，其現(xiàn)象是泄漏、早期磨損、破壞、發(fā)聲等。金屬表面均勻腐蝕有成膜和無(wú)膜兩種形態(tài)，無(wú)膜的金屬腐蝕很危險(xiǎn)，腐蝕過(guò)程以一定的速度進(jìn)行，這主要是選材錯(cuò)誤造成的。成膜的腐蝕，其鈍化膜通常具有保護(hù)作用的特性，但金屬密封環(huán)所用的材料，如不銹鋼、鈷、鉻合金等其表面的鈍化膜在端面磨擦中破壞，在缺氧條件下新膜很難生成，使電偶腐蝕加劇。2，應(yīng)力腐蝕破裂。金屬在腐蝕和拉應(yīng)力的同時(shí)作用下，首先在薄弱區(qū)產(chǎn)生裂縫，進(jìn)而向縱深發(fā)展，產(chǎn)生破裂，稱(chēng)為應(yīng)力腐蝕破裂，選用堆焊硬質(zhì)合金及鑄鐵、碳化鎢、碳化鈦等密封環(huán)，容易出現(xiàn)應(yīng)力腐蝕破裂。密封環(huán)裂紋一般是徑向發(fā)散型的，可以是一條或多條。這些裂縫溝通了整個(gè)密封端面，加速了端面的磨損，使泄漏量增加。二．非金屬環(huán)腐蝕1，石墨環(huán)腐蝕。用樹(shù)脂浸漬的不透性石墨環(huán)，它的腐蝕有三個(gè)原因：一是當(dāng)端面過(guò)熱，溫度大于180度時(shí)，浸漬的樹(shù)脂要折離石墨環(huán)。沈陽(yáng)DG25-30凱泉泵用機(jī)械密封DG46-30凱泉泵用機(jī)械密封。</p><div

迷宮密封效果很好。但在實(shí)際應(yīng)用中，因此而產(chǎn)生的化工泵泄漏卻很多，所以在化工泵密封中不常用，分析其原因主要有：1、密封副(如軸和軸承壓蓋)配合間隙太大，而此間隙與密封效果成反比。配合面粗糙，明顯的螺旋狀車(chē)刀痕在有些情況下也加大了化工泵泄漏趨勢(shì)。2、化工泵軸承室內(nèi)潤(rùn)滑油注入量太多，其溢出壓力超過(guò)了密封阻力。3、油窗或油位計(jì)安裝位置有誤，誤導(dǎo)了人們對(duì)油室內(nèi)潤(rùn)滑油量的正確判斷.4、運(yùn)轉(zhuǎn)中油溫的升高使其粘度降低，增加了化工泵泄漏的可能。5、回油槽或回油孔尺寸偏小，或受到其它障礙，使被阻滯的液體不能順利返回而造成泄漏?；け盟槿〉慕橘|(zhì)有腐蝕、揮發(fā)、等危險(xiǎn)性的存在，對(duì)泵體的密封性能要求，要比其他種類(lèi)的泵高很多。使用迷宮密封，就加大了化工泵輸送物料泄漏的危險(xiǎn)度。所以，化工泵一般不采用此種密封方法?；け妹芊獾倪x擇化工泵經(jīng)常輸送的是具有腐蝕性，或是有毒揮發(fā)的介質(zhì)，因此其密封性能是衡量化工泵好與壞的標(biāo)準(zhǔn)之一。在選擇化工泵時(shí)，應(yīng)參考如下標(biāo)準(zhǔn)。1、密封形式有靜密封與動(dòng)密封之分。對(duì)于靜密封，通常只采用密封圈和密封墊兩種密封形式，而在密封圈中又以O(shè)型圈的應(yīng)用性廣；對(duì)于動(dòng)密封，很少采用填料密封。</p><p> 軸的旋轉(zhuǎn)標(biāo)的目的從右向左看為順時(shí)針標(biāo)的目的,則液體介質(zhì)與殼體的摩擦力為逆時(shí)針標(biāo)的目的,而摩擦力F在該右螺紋的螺旋線上的分力向右,故液體介質(zhì)猶如螺母沿螺桿松退環(huán)境一樣,將液體推向右方。跟著容量的不斷縮小,壓頭逐步增高,這樣,建立起的密封壓力與被密封流體的壓力相平衡,從而阻止了泄漏。設(shè)計(jì)螺旋密封裝置時(shí),對(duì)于螺旋的趕油標(biāo)的目的要出格注意,若把標(biāo)的目的弄錯(cuò)了,不單不能密封,相反,卻把液體趕向漏出標(biāo)的目的,使得泄漏量大為增加。顯然,螺旋密封亦是一種動(dòng)力密封,在停車(chē)或低速環(huán)境下將掉去密封功能,因而往往要匡助以停車(chē)密封,這使裝置復(fù)雜化,且要求有足夠的軸向尺寸。五、機(jī)械密封目前采用耐腐蝕的四氟機(jī)械密封件可以有效的防止液體的泄漏。任何形式的密封都要防止化工離心泵的空轉(zhuǎn)，一旦空轉(zhuǎn)密封就有可能燒毀機(jī)械密封的原理機(jī)械密封又叫端面密封,它是一種旋轉(zhuǎn)機(jī)械的軸封裝置,指由至少一對(duì)垂直于旋轉(zhuǎn)軸線的的端面在液體壓力和補(bǔ)償機(jī)構(gòu)彈力的作用以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置。它的主要功用將易泄漏的軸向密封改變?yōu)檩^難泄漏的端面密封。它應(yīng)用于泵、釜、壓縮機(jī)及其類(lèi)似設(shè)備的旋轉(zhuǎn)軸的密封。機(jī)械密封通常由動(dòng)環(huán),靜環(huán)。KQDP25-2S凱泉泵用機(jī)械密封。</p><div
