增加了化工泵泄漏的可能?；赜筒刍蚧赜涂壮叽缙。蚴艿狡渌系K，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，哈爾濱4660.412飛力水泵機(jī)械密封。6填料密封化工泵填料密封是將富有壓縮性和回彈性的填料放入填料函內(nèi)，依靠壓蓋的軸向壓緊力轉(zhuǎn)化為徑向密封力，從而起到密封作用，哈爾濱4660.412飛力水泵機(jī)械密封。這種密封方法稱為填料密封，這種填料稱為密封填料。由于填料密封結(jié)構(gòu)形式簡(jiǎn)單，更換方便、價(jià)格低廉、適應(yīng)轉(zhuǎn)速、壓力、介質(zhì)寬泛而在化工泵的設(shè)計(jì)中得到普遍采用。填料密封的原理:在機(jī)械行業(yè)中填料密封主要用作動(dòng)密封，常用作離心泵、壓縮機(jī)、真空泵、攪拌機(jī)的轉(zhuǎn)軸密封。填料裝入填料腔以后，經(jīng)壓蓋螺絲對(duì)它作軸向壓縮。當(dāng)軸與填料有相對(duì)運(yùn)動(dòng)時(shí)，由于填料的塑性，使它產(chǎn)生徑向力，并與軸緊密接觸。與此同時(shí),填料中浸漬的潤(rùn)滑劑被擠出，在接觸面之間形成油膜。由于接觸狀態(tài)并不是特別均勻的，哈爾濱4660.412飛力水泵機(jī)械密封，接觸部位便出現(xiàn)。邊界潤(rùn)滑狀態(tài)，稱為”軸承效應(yīng)”；而未接觸的凹部形成小油槽，有較厚的油膜，接觸部位與非接觸部位組成一道不規(guī)則的迷宮。飛力水泵機(jī)械密封FS-S-L90。哈爾濱4660.412飛力水泵機(jī)械密封</p><div

因此能密封含有固相雜質(zhì)的介質(zhì)，磨損小，壽命長(zhǎng)，設(shè)計(jì)合理可以做到零泄漏。但是克服壓差的能力低，功率消耗大，甚至可達(dá)泵有用功率的l/3。此外，由于它是一種動(dòng)力密封，所以一停車立即喪掉密封能力，為此必須輔以停車密封。（2）螺旋動(dòng)力密封螺旋動(dòng)力密封的工作原理相當(dāng)于一個(gè)螺桿容量泵，設(shè)軸上切出右螺旋（或在殼體上、在兩者都刻有螺旋槽），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，在停車或低速環(huán)境下將掉去密封功能，因而往往要匡助以停車密封，這使裝置復(fù)雜化，且要求有足夠的軸向尺寸。8機(jī)械密封現(xiàn)在化工泵行業(yè)使用***的密封形式，由于機(jī)械密封具有泄漏量少和壽命長(zhǎng)等優(yōu)點(diǎn)。哈爾濱7045飛力水泵機(jī)械密封飛力水泵機(jī)械密封FS-l-L28。</p><div

原因四、缺水運(yùn)行造成干磨損壞。此現(xiàn)象多見(jiàn)于底閥式安裝形式進(jìn)口處負(fù)壓，進(jìn)水管有空氣，泵腔內(nèi)有空氣，泵開(kāi)機(jī)后，機(jī)封的磨擦高速運(yùn)轉(zhuǎn)時(shí)產(chǎn)生高溫，無(wú)法得到冷卻，檢查機(jī)封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開(kāi)裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機(jī)械密封。原因五、氣蝕。氣蝕主要產(chǎn)生于熱水泵。由于介質(zhì)是熱水，水溫過(guò)高產(chǎn)生蒸汽，管道內(nèi)的汽體進(jìn)入泵腔內(nèi)高處，這部份的汽體無(wú)法排除，從而造成缺水運(yùn)行，機(jī)封干磨失效，氣蝕裝自動(dòng)排氣閥，更換機(jī)封。原因六、裝配問(wèn)題。安裝泵蓋時(shí)，可能?有裝平，造成軸與泵蓋不垂直造成動(dòng)靜平面不能吻合，開(kāi)機(jī)時(shí)間不長(zhǎng)，造成單邊磨損而滲水。也有可能在安裝動(dòng)靜環(huán)時(shí)，將橡膠件損壞，或動(dòng)靜環(huán)表面碰傷。處理辦法：拆除重裝，檢查泵蓋是否裝平。2機(jī)械密封處滲?水的第二種可能性是機(jī)械密封膠失效。機(jī)械密封膠失效的原因：橡膠件老橡膠件的老化、變形，主要是熱水泵中的化、變形。機(jī)械密封膠失效表現(xiàn)的現(xiàn)象為水溫過(guò)高，介質(zhì)溶解橡膠。從外觀上看橡膠件表面疏松、?糙，失去彈性，從而使橡膠失效。處理辦法：更換適合的橡膠材料。3機(jī)械密封處滲?水的第三種可能性是泵蓋靜環(huán)室造成。主要原因是靜環(huán)室內(nèi)孔加工尺寸誤差大。</p><p> 盡量減小變形,可采用硬質(zhì)合金、陶瓷等耐壓強(qiáng)度高的材料,并加強(qiáng)冷卻的潤(rùn)滑措施,選用可*的傳動(dòng)方式,如鍵、銷等。(2)真空狀態(tài)運(yùn)行造成的機(jī)械密封滲漏泵在起動(dòng)、停機(jī)過(guò)程中,由于泵進(jìn)口堵塞,抽送介質(zhì)中含有氣體等原因,有可能使密封腔出現(xiàn)負(fù)壓,密封腔內(nèi)若是負(fù)壓,會(huì)引起密封端面干摩擦,內(nèi)裝式機(jī)械密封會(huì)產(chǎn)生漏氣(水)現(xiàn)象,真空密封與正壓密封的不同點(diǎn)在于密封對(duì)象的方向性差異,而且機(jī)械密封也有其某一方向的適應(yīng)性。對(duì)策:采用雙端面機(jī)械密封,這樣有助于改善潤(rùn)滑條件,提高密封性能。三、由于介質(zhì)引起的滲漏(1)大多數(shù)潛污泵機(jī)械密封拆解后,靜環(huán)和動(dòng)環(huán)的輔助密封件無(wú)彈性,有的已經(jīng)腐爛,造成了機(jī)封的大量滲漏甚至有磨軸的現(xiàn)象。由于高溫、污水中的弱酸、弱堿對(duì)靜環(huán)和動(dòng)環(huán)輔助橡膠密封件的腐蝕作用,造成了機(jī)械滲漏過(guò)大,動(dòng)、靜環(huán)橡膠密封圈材料為丁腈—40,不耐高溫,不耐酸堿,當(dāng)污水為酸性堿性時(shí)易腐蝕。對(duì)策:對(duì)腐蝕性介質(zhì),橡膠件應(yīng)選用耐高溫、耐弱酸、弱堿的氟橡膠。(2)固體顆粒雜質(zhì)引起的機(jī)械密封滲漏如果固體顆粒進(jìn)入密封端面,將會(huì)劃傷或加快密封端面的磨損,水垢和油污在軸(套)表面的堆積速度超過(guò)摩擦副的磨損速度,致使動(dòng)環(huán)不能補(bǔ)償磨耗位移。飛力水泵機(jī)械密封FS-O-L45。</p><div
